Are Some Physics Questions Just Impossible to Answer With Our Current Brains?

AI Thread Summary
The discussion centers around the limitations of human understanding in physics and the philosophical implications of fundamental questions about the universe. Key points include the nature of matter and energy, the concept of time, wave-particle duality, and the electromagnetic force. Participants express skepticism about whether certain questions can be answered scientifically, with some arguing that they are philosophical rather than scientific inquiries. The role of metaphysics in understanding these complex topics is debated, with some suggesting that modern physics has parallels to ancient religious paradoxes due to its inability to fully explain certain phenomena. The conversation highlights a tension between the pursuit of scientific knowledge and the inherent limitations of human cognition, questioning whether advanced concepts may always remain beyond our grasp. Overall, the dialogue reflects a blend of scientific curiosity and philosophical exploration regarding the nature of reality and our capacity to comprehend it.

I thought Feynman was being a little sarcastic or ironic when he said that; in that the statement itself was on the 'philosophy of science', and that 'philosophy of science' could be that far beyond the reach of scientists as birds trying to understand ornithology; but, the key word is 'useful'.

WOW whopper of a post! Alright, well then if those questions are not science, I would say that since scientists are usually people seeking to understand the nature of the universe, wouldn't philosophy be just as important as science regarding this stuff?

Also, wouldn't things like the theories about parallel universes and multiple dimensions also be philosophy? Because there is no way to empirically experiment to test for these things.

Going strictly by physics as a science seems to be a bit limiting in understanding the nature of things.

Regarding what would be the criterion or experiment for figuring out what the electromagnetic force actually is, well I don't know, but how do we know for sure that equipment just does not yet exist to be able to experiment in this sense? Or that our minds are just not developed enough.

To say it (electromagnetic force) is just a mathematical abstraction just seems too limiting to me. There has to be something there. Positively-charged objects do not just magically pull towards negatively-charged objects (whatever a "charge" even actually is). And similarly-charged objects/particles cannot just magically repel one another. It may be understood strictly via mathematics, and is beyond the scope of our senses and capabilities to be understood any other way, but that doesn't mean it is solely an abstraction.

Ultimately to us humans, these questions do not matter in terms of engineering and practical everyday life, but in terms of pure truth-seeking, saying they do not matter to me would be like being back in ancient Greece and pondering, "What is everything ultimately made of?" and someone saying, "WHO CARES, none of that means a bit of difference to our lifestyle."

yes, but how many of the 'things' that you're talking about are 'known' and how many are just 'accepted'? Earth was the accepted center of the universe at one time.

What I'm saying is that scientists often present what they 'know' as the 'truth' when is really just the 'accepted knowledge of the day'.

Which is why my statement was directed at Zapper and his use of the quote, and not directed at Feynman. :smile:

'Some scientists' , when they see a question with a "why does...?" or "why is...?" seem to go somewhere in their heads, and say "why is a question for philosophers"; and its bothersome to me.

Is it coming from a fear of being called or thought of as a 'philosopher' by their peers if they do answer, or has the question(s) got to a point where they know that there is no really good answer, and they pull this old saying out of the bag so they don't have to say that?

You implying that Planck anything, the Big Bang, etc can even be scientifically proven?
No, of course not, they are defined as our (current) limits of observation and measurement. They can be "hypothesized" as unobservable parameters of a mathematical model. My point is that (the current values of) these limits envelop all (currently) possible observation and measurement. In this sense, they are "proven" by our inability to see beyond them.

Good, good, your starting to get it more now. Yes, it does seem limiting to regard Physics as the be-all-end-all of universal knowledge, and thus why I have an interest in philosophy/philosophy of Science. Now, I don't claim to know all of this, or the answers, I'm just trying to clarify some thought so you can think about these things in other ways that may or may not turn out to be more fruitful. Regarding the charges repel and what not, I agree, I think there has to be some reason why they do that, and their are several ways to look at that, one being that Physically there is something out there causing these charges to attract/repel one another and we are defining it tautologically with the electromagnetic force, and there is something that it "really is" causing this to happen, and that comes more naturally I believe. The other way to thing about it (Among many more) is by examining perception and noticing how many concepts and ideas are simply a facet of sensations passing through our human minds and being categorized and defined relative to other sensations, and thus you get to one of the kind of conflicts of modern science, the reductionism vs holism and how to interpret these things idea. Meaning, is this just the way the universe as a whole functions and the charges are two sides of the same coin (one hand clapping?) and our human minds are categorizing them as different things when as a process that is simply how the universe functions. At which point you could say that this holistic argument could have been used all along and are reductionism/isolation of "individual" objects has worked very well, and that is true, though as science goes on we can't define things without reference to their interactions, system and environ.

Finally, I do not want to project the "Who cares" attitude because I do care about these issues, and I think they are interesting/important and most wouldn't consider me particularly pragmatically minded, maybe what I'm trying to say is that when you understand it more it is like asking the question of "What does God look like?" In that it is a real question, but (assuming you believe in any type of God) once you gain a better understanding regarding the nature of God,spirituality and religous experience you see that asking "What God looks like" is kind of the wrong question to ask.

Back when science and philosophy were the same thing practiced by the same people it was determined that heavier objects fall faster than lighter ones.

I like the way that some scientists say--"if we (YOU) fund this (give me money to fund MY idea), it WILL answer questions that we (I) have been wondering about for years, and help solve the (insert a 'need'/problem) crisis."

Well I certainly do not take a "who cares" attitude either to these questions. I still am not sure if I'd consider these questions philosophical questions per se though. Philosophy, to me, is stuff like what is good and evil? Do good and evil really exist or are they just constructs invented by humans? Saying, "What is the electromagnetic force?" well modern physics may be unable to answer that for all intents and purposes right now, except mathematically, but I do not see it as philosophy. The electromagnetic force is something real and tangible, just not in the normal physical sense in how we humans understand things. Same with light. But it's there.

Well heavier objects would have a greater gravitational force, thus a greater acceleration. So then shouldn't heavier objects fall faster?

Heavier force, yes. Acceleration, no.

Think of it this way. At the center of the Earth there is this strongman. He has a rope tied to a big object, and a small object, which are on the surface of Earth. He is pulling with the same rate on each object, but obviously the heavier object requires more effort, and the smaller object requires less effort.

There is a difference though.

If you have studied QED, and have dealt with the issue of field theory, etc., and then you ask "Gee, what really is an electromagnetic force beyond these description?", then I would be VERY interested in hearing what you have to say. Because if someone who has done all he/she can to understand it still have some leftover issues in trying to figure out what and why, then there's something to that.

But if all you had was an intro physics course, and then not only that, you THEN draw up the conclusion based on that level of understanding that the nature of electromagnetic force is just impossible to answer and beyond the capability of our minds, then I would dismiss that question immediately.

In the former, I don't have tell the questioner that he/she is missing a large portion of our current knowledge. In the latter, I have to not only counter the conclusion, but I may even have to spend a lot of time and effort teaching the basics first, something which that questioner should have put effort in before drawing up such conclusion. The propensity to simply draw up some conclusion without first figuring out if one has ample knowledge and information to even make an accurate conclusion is appalling.

Actually, we DO know.

For example, the question on light being "wave" or "particle" has been addressed in our FAQ. Matter and "energy" are the same ONLY if one cares about "energy accounting", and nothing else. That's like saying an apple and an orange is the same IF you only care about "fruits". And we do know about "electromagnetic force" because QED is one of the most successful theory with the highest accuracy when compared to experiment. QED has more certainty about EM fields that you know about yourself! And yes, there ARE more than 3 dimensions. There are at least 4 that we know of (3 space, and 1 time). And related to this, if time is a "concept", then so is space. If time is a "thing" then so is space.

So you do know, but on the first page you were saying things like this...
The questions being asked are based on rather an incomplete understanding of our current understanding. They are also rather vague in terms of what the question is really asking.
Were you just giving him a hard time at first? Instead of stating that those questions had answers, he was being told that his questions weren't scientific. Whatever that means.

I was thinking the more accurate way to say it is, 'Actually, we DO know a lot about them'---but everything isn't known about them--and some things are more known 'about' than others.

as in Z's:

If you have studied QED, and have dealt with the issue of field theory, etc., and then you ask "Gee, what really is an electromagnetic force beyond these description?", then I would be VERY interested in hearing what you have to say.

Until the next step of 'knowing' comes out, people/scientists won't know how much we didn't know.

So you go from the questions are unscientific to "I don't want to answer your question because it's clear you have minimal understanding?"

Here I thought that this website was designed to help those people who have minimal understanding in various subjects to gain a better understanding. Yet, here we have a mentor of the forums, a scientist himself, saying that he won't answer the question merely because it's based off a 'intro physics course'... For instance I would say I had very minimal knowledge in cosmology but when I posted my 'minimal understanding questions' they were met with answers to set my thoughts straight. No one came at me with 'LOL you do'nt even know what your talking about so I'm not going to help you understand'

Very interesting...

And again, you MISSED THE POINT, especially when I've already mentioned this stand clearly in this thread earlier on.

If the question was about wanting to understand something, fine. But it isn't. It is about wanting an answer based on an already-made conclusion about the nature of something.

If you had ALREADY DECIDED about the nature of wave-particle, and then want me to answer to your question on why it is impossible to understand such a thing, then it is futile for me to answer and correct such ignorance when it is based on limited knowledge!

Sigh... this is getting nowhere. So go ahead and draw up your own conclusion about me or this forum. After all, this is what this thread is good at, which is making up conclusions based on faulty premise.

I do know of the NATURE of the questions if I were to GUESS at what is being asked based on what has transpired. If someone were to walk to me and ask me "Do you know think we know what electromagnetic force is?", then I would certainly respond and try to explain. In fact, people HAVE asked me that since I run an outreach program often and also have welcomed the general public to our facility many times a year. I love nothing more than to answer such questions, because many members of the public do not get to interact with physicists very often, and when they do, it is understandable they have TONS of questions to ask.

But then, that isn't the question being asked, is it? I mean, look again at the original question related to the electromagnetic force and within the context and premise it was being asked. "What is an electromagnetic force?" is being asked within the premise that we really cannot understand (impossible?) it "... with our current brains"? Under THAT premise, do YOU think it is "scientific"? All I did was answer the question while completely ignoring the original premise of the OP.

I'm drawing conclusions based upon what has been stated in this thread. Questions are unscientific. Even if they ARE based upon a faulty premise that makes them no LESS scientific and it means you should CORRECT that premise. Not just brush it aside because the person only has a 'intro level physics course'.

You should feel as if it's your DUTY even, since you ARE a scientist, to make sure that the correct scientific knowledge and understanding is being tossed around on these forums. Regardless of if you're a mentor or not and regardless of if this forum is for mainstream science or crackpottery. You should always try and help those who pose questions.

There was no premise given that it is impossible to answer the questions which the OP posed. It was a question of IF we can EVER understand some questions in physics with our current 'brain' power. I would understand this to merely mean 'can we answer all questions that will come from physics given the limitations of being human. (so like how we perceive things in our universe etc.) This question can be both philosophical AND scientific.

The questions within the OP itself though are scientific, no doubt about it in my mind. As well, as far as I know, there is NO current understanding of what exactly any forces are. We know how they operate etc. but not exactly what the fundamentals are. Just because we don't know this information currently does not mean we never will and does not imply that this question is unscientific.

It seems to me that this thread has turned more into a scientist attempt at bashing philosophy more than anything else. (even though philosophy is only minimally involved and it's not even involved in the way some people are trying to present it)

And that is not how I understood the questions within the premise of the OP. And that is how I addressed it BASED on that understanding. And was answering it based MY view, not from how Russ viewed it.

I don't believe that that is what this thread is good for--first, I recognize that that is your opinion; secondly, this is a discussion; next, you're implying that the entire thread is faulty, and going nowhere, and making up conclusions.

Z, you sound frustrated. Almost as if you don't like discussions about philosophy---or being involved after you do get involved. People do have different opinions--that's what makes a discussion. This is a discussion.

Sometimes the thread title and the first post are only that, and sometimes they're over the top, like that 'blue tits' thread. Most people are coming from "an already-made conclusion" even when they do pose a question---its meant for some discussion, and getting other people's opinions.

here's my 'my, my, my...'

geez, I don't think any of us were expecting a 'correct' answer---and put on the weight on you to do it, and entirely on your shoulders to resolve the issue.

Ignorance...

Ignorance, WHAT ignorance?

you seem to like using that word and I personally think using it escalates the 'discussion' to an argument (the negative type). Are you implying that everyone who gave an answer has 'ignorance' ? and its your job to correct it? my, my, my...

I'm sure everyone, and I mean everyone is ignorant-------to some degree about something; I don't like being called it, if I was the one you were talking about, because you really didn't say, you just implied (everyone), and I don't believe most other people would like it, including yourself of being even imply of being 'ignorant'.

I thought at the beginning that this may be an interesting thread, and it is. It's a discussion about science, philosophy, and the both the science of philosophy and the philosophy of science---and the questions of the first post, and the philosophy and science of the questions of the first post (plus the rest of the thread, that includes the minor topics too).

(my, my, my...

Perhaps the question could be restated in a different way. It is an interesting idea that there may be some problems that our brains can't conceive of solutions to. Those questions the OP asked may have answers, but is there some inherent limit to what our hardware can solve for? The most obvious example of an "unanswerable" question to me is the causality paradox.

Certainly. I definitely recommend the OP reformulating those questions and asking them, one at a time, in the physics sub-forums, if he/she really wants to learn, before extrapolating and making conclusions. Get an understanding first before concluding that there are no answers to them.

  • #77
if they were put in physics sub-forums they would be different. They become 'physics' questions then.

I went back and re-read the original post. The idea of the original post isn't completely and/or exclusively concerning 'physics' questions. It doesn't belong in a 'physics sub-forum'.

The discussions like this are a way of getting a better understanding. Very few people know or do the things that you do, and for them a "Get an understanding first" to the level that you accept before they ask a question may be hard to do.

If anything, it may belong in the 'philosophy' forum, but a lot of other similar question are in general discussion and haven't been moved---



Normally when you don't like a thread, for whatever reason, they often get 'locked'---the person comes down here to complain, then that 'complaint' thread disappears---it's funny that of the ones I've looked at, the thread was somewhat diverted and the word 'ignorance' was often used.

What's interesting is that the thread was doing fine. I think we get away from Z's dislike of the thread and re-start/ re-set the discussion back to the topic.

I didn't say there are no answers to them, but I do not see how humans at the moment can for example understand the exact "what" the electromagnetic force is that causes say a proton and electron to attract one another. Sure mathematically perhaps, but that's it.

I think all your questions can be answered---maybe the answers aren't 'known' (yet). The way I see it that if we have enough talents to go to the moon and built things like the LHC, they may just come to be 'known' someday.

I've read some of the things written about Einstein (even though I don't agree with him) about his theories. Some comments about his theory were positive (protons) and some negative (electrons).

If you do read some of the things he wrote, like even the more common of his quotes, they can be more philosophical about the way things are than some (scientists) like. I can't remember if there was any in writing if he read any of the eastern religious writings, but it sounds like it.

So sorry, I am still confused though. You say, "Some comments about his theory were positive (protons) and some negative (electrons)."

How could comments about the theory be positive or negative in that sense? I mean there are positive comments (meaning approval) and negative comments (meaning disapproval) but those uses of the words "positive" and "negative" are different from referring to the electrical charges that we call "positive" (which protons are) and "negative" (which electrons are).

Well, in the case of the EM force, there are descriptions in the standard model at the quantum level that account for it. Perhaps what you mean is that at any level of complexity you can hypothetically reduce to a more basic why, and there would seem to have to be some point where you say "that's just the way it is?"
 
  • #84
You could say that, but to me what that really means is, "That's beyond our ability to understand in that sense right now."

It's like creation of the universe. Where did all this stuff come from? Has it always existed? Has time always existed? How could existence of time have a "start?" If someone created the universe, who created the creator? Those questions are again beyond our ability to understand and for all practical purposes don't matter, but I am sure there are answers to them, just beyond our reach.

This is the "causality paradox" I was referring to. This same paradox can be applied to regression of levels of complexity. I think what people were getting frustrated by was that you choose a level of complexity for which there does exist a simpler descriptive causative level. By saying that lacking an understanding of a phenomenon at all possible levels of causation is the same as having no understanding, you have eliminated all possible knowledge due to the nature of this paradox. So I understand what you are trying to say, but your point is a bit muddled, since saying we can't undertand the electromagnetic force because there is some level of causation at which are understanding cannot reduce is like saying we don't understand Newtonian mechanics, or anything else for that matter, because the same argument applies.

Well THOSE questions are more philosophical because we can not observe the creation of the universe so questions of 'where di the stuff in our universe come from' are much more philosophical than scientific. We do have very good models in cosmology of these sorts of things but they are by no means the 'answer to everything'. For all we know everything done in the field of cosmology could be completely wrong.

As well I do not think that a question of 'what is the fundamental level we can get to of what we perceive' the same as 'what is fundamental of everything in our universe.' These are two very different questions one is scientific one is philosophical. The fundamentals of say forces we possibly COULD figure out becaues we can observe them right now. The fundamentals of 'where those came from' or 'what created the fundamentals' is merely philosophy being a nuissance. Sometimes questions really do go too far and can not be answered in any way empirically or logically... so they are better left alone.

The questions you asked in the OP however I didn't take in this sort of 'creation fundamentality' but if that WAS what you were meaning then I take back everything I had said about your questions being scientific and jump on the wagon with Zapper.

I'll use Einstein for example again. Not working in the 'field', wasn't a great student, may or may not have done too much lab, and sat around wondering what it'd be like riding on a beam of light

So sorry, I am still confused though. You say, "Some comments about his theory were positive (protons) and some negative (electrons)."

How could comments about the theory be positive or negative in that sense? I mean there are positive comments (meaning approval) and negative comments (meaning disapproval) but those uses of the words "positive" and "negative" are different from referring to the electrical charges that we call "positive" (which protons are) and "negative" (which electrons are).

I was playing with words---there is the idea of positive and negative in a lot of things, and often 'things' come out of it---positron and electron, sides of a debate, questioning a theory---who know how much of some of today's theories came out of debates on earlier theories.

That's great, you can observe a beam of light and make measurements on it. What's your point again?

you're may be thinking of it in the present day---with the present knowledge...

if you were there when Einstein was not working in the 'field', wasn't a great student, may or may not have done too much lab, and sat around wondering what it'd be like riding on a beam of light, you may have thought that this line of question "really do go too far and can not be answered in any way empirically or logically... so they are better left alone."

It almost sounds like you're against theory work, because it can't be taken any farther, are you?

You're telling me that because we didn't understand what light was that we couldn't see it? That's just plain ole rediculous. Just because he took an unconventional way of looking at things which no one thought about doesn't mean he COULDN'T perceive light.

We CAN NOT perceive the creation of our own universe there ARE limits to what we can observe.

I don't where you got that from what I wrote, sorry.

You counter:

"I'll use Einstein for example again. Not working in the 'field', wasn't a great student, may or may not have done too much lab, and sat around wondering what it'd be like riding on a beam of light"

I say:

"That's great, you can observe a beam of light and make measurements on it. What's your point again?"

You say:

"if you were there... you may have thought that this line of question "really do go too far and can not be answered in any way empirically or logically... so they are better left alone.""

So I'm saying that as long as something is possible through observation it is FIRMLY in the grounds of science. Einstein was STILL conducting science when he talked about 'what it would be like to ride on a beam of light'. It's as if you think you are countering my original claim because you think that Einstein was 'outside the field' at the time. IT DOESN'T MATTER ABOUT WHAT THE FIELD DID AT THE TIME. What DOES matter is that he could use empircal DATA or justify empircal experiments to COLLECT DATA in order to seek out his answers. What the REST of the scientific world thinks DOES NOT MATTER.

Why? BECAUSE LIGHT IS OBSERVABLE. He WASN'T sitting there wondering 'where did all this light originate from?'. If he DID do this then it jumps into the realm of PHILOSOPHY. More specifically I think that the question would fall into the category of METAPHYSICS. (Which is where cosmology lies.)

there is the big bang theory, if that's what you mean (?)
What does the big bang theory have to do with the creation of the universe? (I'll tell you it's very little to nothing.)

which one is 'scientific' and which is 'philosophical'?
I wonder...

"What are the fundamental particles of matter"
VS.
"Where did ALL fundamentals come from?"

One of these questions is firmly in the realm of science, the other is firmly in the realm of metaphysics...

So does this mean things like string theory are philosophy, or does that have actual empirical experimentation to it? Or there being more than three dimensions? Or what happens when something enters a black hole (there is a battle going on about this right now, covered in the book The Black Hole War. Are all of these philosophy?

I would say a question regarding the literal "what" that is the electromagnetic force, may be philosophical in that science cannot answer it, but I do not think it is a question lacking a solid answer. Just it is beyond the capabilities of humans and science to answer it right now.

Well most of the things you talk about can be verified through experiments, that is to say they are FALSIFIABLE. As well most THEORIES are based on philosophies, mathematics AND science. They also can use each other, for instance using science to prove something philosophical. That doesn't mean that if you ask a question which can utilize science that it is automatically scientific, it may very well just be philosophy.

I can see now why Zapper and russ jumped the gun with what you asked, somehow they saw it before it even happened. But your question isn't even philosophy OR science. More of 'pseudoscience' I would say. Why? Because you are arbitrarily saying that what we know the electromagnetic force IS isn't good enough. Support this position a bit and I might reply... it kind of sucks that I was defending your questions and you come out with this :smile:. Now I do look like the ignorant type of person that ZZ was talking about.

zomg, there is absolutely nothing wrong with defending people. Heck, I sometimes defend people I disagree with, because I feel the attacker is being unfair.

What I get from Nebula's questions is, what does all this really mean? It's one thing to say that light is hv, but that's quantitative. I think he's looking for qualitative answers. For example, we can explain the EM field well with math. But could you explain it well without (much) math?

Things like string theory, there being ten dimensions, what happens in a black hole, cannot be verfied with experiments from what I understand; they are all theory.

In terms of pure knowledge-seeking, it is nowhere near good-enough. In terms of engineering, sure it is plenty good enough. But then again, in terms of chemistry, one only really needs to understand matter in terms of protons, neutrons, and electrons.

All that stuff about quarks, leptons, gluons, and all the other particles scientists keep finding are worthless for all practical purposes.

All we really "know" about the electromagnetic force is the mathematics of it and how it behaves. That is my point. No scientist can tell you exactly WHAT causes a proton and electron to attract themselves to each other. No scientist can tell you exactly WHAT a "positive" or a "negative" charge even really are.

All we know is that what we label as "positively" charged and what we label as "negatively" charged particles attract to one another.

But there is no way to really understand what causes the pull between differently charged particles, or the resistance between similarly charged particles.

Teleport yourself back to the early 1900's, and I bet you'll be one of those who will make the same complaint against the SR and QM. But besides the basic knowledge aspect of it, which we have seen throughout history to eventually find direct practical applications later on, there's also a completely lack-of-information here on all the http://www.iop.org/News/file_34737.pdf" - everything from synchrotron light centers to the x-ray machines in your doctor's office.

Here's an apple. Can you tell me WHAT an apple is? Now look at your answer and all you have is a series of characteristics and properties of an apple. If you think you "know" what an apple is, I can tell you that you don't know it as well as what physics knows about electromagnetic force.

Your response here have rather strengthened my original assertion that you have no interest in discovering if your original premise was even valid. Even in philosophy/logic, it is well known that a faulty premise can give you all kinds of ridiculous outcomes. This is going along in that direction as expected.

It is also strange that you question about the practical application and usefulness of basic knowledge, and yet this thread is edging on towards a "philosophical" discussion without you questioning the practical application of such a thing.

toward a "philosophical" discussion? This is a philosophical discussion.---and you're part of it!

Congratulations Z, you're a Philosopher!

are you trying to approach this discussion as a scientist? if you are, your approach isn't very scientific---its more from your philosophy.

that exact idea has been brought up in many other discussions/threads. Both a new debate and a new theory start out with a hypothesis usually, but the next steps can go into different paths. A theory is only a theory until it can completely be verified to some extent.

and, that's another reason why there's the idea/area/'label' of Theoretical Physics (I capitalized them to show their importance).

I think it is important for people to have a firm understanding of the science, mathematics and philosophy behind their conclusions. So Nebula go ahead and show the understanding of the principles behind your conclusion.

As well the comment you made about The Black Hole War, what exactly are you saying? That this book shows that Hawking and Susskind disagree on what happens to information when it enters a black hole? I thought the disagreement came from what happens to the information once the black hole has evaporated... (hawking says it's gone forever susskind says it's still there)

@reweb
Are you purposely attempting to be annoying? It seems to me that most of your posts in this thread have only been directed in order to get some sort of response. If you have a point make it if you don't well then... (it wouldn't hurt if you actually took in and understood what was being said. Where did I give the impression that I'm at all attempting to approach this from any particular point of view? Of course I'm not approaching it from the view of a scientist, I'm not a scientist.)

It seems to me that one thing has been forgotten about completely: mathematics. As well it seems to me that people are assuming that because something incoporates 'philosophy' that it IS philosophy. Or that because something incoporates science it IS purely scientific. This is wrong and was not what the original responses were about.

As an aside how can you completely verify something 'to an extent'? It's either it's verified to an extent or it's completely verified...
