I believe you must have misread my post.

I disagree with Wikipedia. A fundamental particle is described by a set of both quantum numbers and a mass, that is not quantized, or at least not known to be quantized.Openeye said:"In particle physics, an elementary particle or fundamental particle is a particle believed not to have substructure; that is, it is believed not to be made up of smaller particles."
-Wikipedia
How did they scientifically conclude that any particle is elementary? And was it the same process in which we've found ATOMS to be 'elementary'?
pallidin said:The concept of infinity IS a fundamental consideration in physics.
We see it all over the place: In mathematics we have pi, in cosmology we have a universe that we can not comprehend as having an end.
"Infinity" is not being ignored at all, it's just that it's not understood.

kaksmet said:Hey there. I must admit that I do not have the time to read all of the posts in this thread so forgive me if some of my comments have already been mentioned before. However,
I will try to discuss some of the issues and concerns you raise..
kaksmet said:Energy can be created, and it can be destroyed. In fact, that happens all the time and everywhere around us. What can happen is that for a short time energy can be created, notably particle/anti-particle pairs forming from the vacuum.
kaksmet said:Also, the notion of particles, i.e. how we understand the word in ordinary life does not apply at small enough scales. At very small scales, experiments in physics show that the "particles" have some properties which is similar to our ordinary notion of particles, and other properties which they share with what we usually call waves.
kaksmet said:However, this does not mean that we should not continue the discussion, only that we sometimes have to be careful and remember that thinking about them as ordinary particles is not entirely justified.
kaksmet said:No, that something cannot be broken apart does NOT mean that it is indestructible.
kaksmet said:To explain this with an example we can imagine for a second that water is the most fundamental thing (off course not true, but let's imagine), without destroying water we can change the form of it, it can be solid, liquid or gas.
Going back to the case in particle physics, the particles consist of mass which is one form of energy, when they collide they have momentum which is another manifestation of energy. The energy of the colliding particles can then be transformed into some other form of energy, for example, other new particles.
kaksmet said:With composite particles, such as the atom, proton and so on so forth, collide with each other one observes a specific scaling with energy, i.e. a difference in the probabilities for interactions to take place. Today, we have been colliding quarks and the likes inside protons for many years, but no such scaling have been observed for the quarks. What I mean is, that long before one have enough energy to smash the particles, one can observe indications of the composite nature. Since that has not been seen, there is at least more ground than before to believe that the particles might truly be elementary.
kaksmet said:What happens at CERN (at least the colliding particle part) happens all the time in the universe, it happens inside stars, it happens in the "empty space" around our galaxy, it happens in our atmosphere, inside Earth and even in our own bodies. Yes, some of them are of a type which cannot survive alone and hence they must quickly transform, others can survive, perhaps forever.
kaksmet said:This is quite right, the particles named elementary in the Standard Model are thought to be without size. The electron take up zero volume and is only a point, which is quite like saying that it is 'infinitely small'.
ZapperZ said:It is one thing to ask question. It is another when you're PROPOSING something that is based on ignorance. We welcome the former, we do not allow the latter.
ZapperZ said:Please note that you have, implicitly, accepted what we accept to be true.
ZapperZ said:Your very use of modern electronics (at least, that's what I deduced by your ability to post on the internet) testifies clearly to that! You just were not aware of your acceptance.
ZapperZ said:It is one thing to ask question. It is another when you're PROPOSING something that is based on ignorance.
ZapperZ said:You might want to consider if what you're questioning is really about "elementary particles" or really science in general. Do you also study medicine inside out before you accept medical advice?
ZapperZ said:Do you meticulously study aerodynamics and engineering before you buy a plane ticket?
ZapperZ said:If not, why this focus on something that you clearly have a huge gap in understanding the basics-elementary particles? Are you questioning it based on an intimate knowledge of it, or simply based on superficial understanding of what it is?

These numbers found stuck-together in the process of measuring them. And so when these numbers are stuck-together, its called a particle. And when these numbers are stuck-together, in the simplest manner that can be discerned, they are called a fundamental particle.
Openeye said:What am I proposing? I don't get it...
Openeye said:"In particle physics, an elementary particle or fundamental particle is a particle believed not to have substructure; that is, it is believed not to be made up of smaller particles."
-WikipediaHow does someone ever possibly (LOGICALLY) conclude that a particle is not made up of smaller particles? Especially when the way in which they discover particles is by bashing them together which would CREATE smaller particles (not really create, but through division) if they didn't exist before.
Surely when we fail to break open the next smallest particle, it's always going to be a question of whether or not we can build greater technology to bash them open, yes ?
If a particle can NOT be smashed/broken apart into pieces, then it is truly indestructible... yes?
HOW do we get away with assuming there is such a thing as an indestructible particle... when there is absolutely no evidence anywhere that anything physical is indestructible and can not be broken into more pieces? Where is the evidence? That's what scientific theory is supposed to be based on yes... not blind faith?
We even have evidence of "elementary" or "fundamental"particles being proven not to be so:
"Historically, the hadrons (mesons and baryons such as the proton and neutron) and even whole atoms were once regarded as elementary particles."
To me it seems we have much more evidence of this logic being illogical, than we do to suggest that there is such a thing as an indestructible particle. Why is this persisting?
1. First WANT to try to make sense of my line of thinking (NOT to accept it as 'truth' or 'valid'... but to understand WHY I'm thinking it so we can communicate most effectively)
and
2. translate what they know into language that they believe makes sense to me.
And what difference does that really make what my context is when I'm coming here to understand what YOU'RE ('accepted science') saying? I'm amazed at how many times people are chiming into basically say the same thing about me, that I have an 'agenda' or almost paranoid about my intentions/motives like I'm trying to break the walls of their house down. If you think I'm trying to do that then why'd you come into the thread I created?
Did you intend to help me with your communication here? Can we call upon a moderator so I can know once and for all whether or not I'm really violating any rules here?
Is that what it means to be a mentor? Are you a mod? I just read the rules and I'm not observing any lines that I'm crossing by asking these questions... please be specific if you're going to say I'm breaking rules, I don't know what you mean.
Thanks, and sorry for the ignorance you've observed in me. :P
That's why I'm here, actually. Again, if I'm really a bother, please can you direct me to a physics forum that is more allowing of freedom of speech/ideas/logic being openly discussed and questioned for various people's interpretation? I haven't yet grown attached to anyone here, and I don't think any here has of me... so... it's not like I'll be heartbroken :P
ZapperZ said:Fine, let's look JUST at your first post, shall we?
If you were to JUST ask "How can we know something is an elementary particle when we can smash them to produce other particles?", you would have been given a lot of answers. But nooooo. It appears that you can't wait to get the answer to such a question, but rather proceeded question the "logic" in what we currently call as "elementary particles". It is as if a bunch of physicists simply threw out any kind of logic and ignore the most obvious part of the history of physics by calling something as "elementary particles". This is why you got the type of reaction that you got!
ZapperZ said:But again, this is exactly my point. It appears that you question all of what is accepted in science, not just what is accepted as elementary particles. So the "debate" here isn't about elementary particles, but rather how do we know what we accept to be valid is really valid? To be, that appears to be your central principle. So rather than tackle what is obviously merely an example of the application of that principle, it would have been more fruitful to tackle that central principle and see where it breaks down! But before that can happen, there must be that realization that you are using some central principle. If not, if you only pick on fundamental particles while ignoring the fact that you don't have a problem elsewhere, then this is highly inconsistent! Which was why I was curious on why you only picked on "elementary particles".

Openeye said:Like I've previously stated. Until something makes sense to me I don't accept it. Is that really a problem? And is it a problem for me to ask questions in attempt to understand how it makes sense? Just because a thousand people or however many it actually was collectively came together to provide these theories, doesn't make them 'the way'... it makes it 'THIS way'. The elementary particles may have just been the catalyst for me to reach the information I need. Is that ok? I agree that this topic has taken a shift in direction since this realization, hence that's why I asked in a previous post if I should start a new thread (and on multiple occasions have been asking where to do so).
I don't blame you for not reading all of what I'm saying... it's a lot of text... and who am I? I'm not speaking in the ways you most clearly understand. That's why I only want people to read if they want to :P Again, I figured that's what people would do anyway... seeing as we seem to have free-will in a sense, and all.
Thanks for your input :)

ZapperZ said:It is fine to want to have things "make sense". However, I can also do what you did by point out that what used to "make sense" no longer does, and what used to not make sense is now common place! The consequences of Special Relativity, for example, used to not make sense, not just to ordinary people, but also to physicists, so much so that they didn't award Einstein the Nobel Prize for Relativity. So relying on "common sense" has been shown to be faulty, the same way that we used to think that baryons were elementary.
ZapperZ said:The way science works is that at any point in time, the state of knowledge of what's known and verified is the best that we can know at that time.
ZapperZ said:So as far as we know, the set of elementary particles that we have are just that until we can know more. All the physics that we have done in the study of, say, electrons have indicated that it has no structure.
ZapperZ said:But we all know that things could change, and this is where it is crucial to understand on how such change can come about.
ZapperZ said:One either produce empirical evidence whereby what we observed just simply doesn't quite match our current understanding, or one produce a new theoretical description that differs from our current understanding that can be empirically tested and verified. There's nothing here that relies solely on "common sense".
ZapperZ said:In fact, producing empirical evidence and verifiable theories are definitely stricter criteria and requirement than simply using "common sense", and that is how it should be. This is not, say, politics where one can simply try to convince another person of something simply by appealing to "common sense" that can be faulty.

Drakkith said:Yes. I don't understand how a computer works at the most basic level, but I use it everyday and since it DOES work I have no choice but to accept it. The fact that it is working and I am using it is the evidence that the science behind it is correct.
Drakkith said:Sure. THIS is the way we look at it now. However, there are no contradictary things happening that make us believe that there is another way other than THIS way.
Drakkith said:You've been missing the whole point this entire thread. Even if you don't understand HOW or WHY something is the way it is, it does NOT make it ok to simply say you don't think it's correct and then try to tell everyone it isn't.
Drakkith said:Now, it seems to me that no one here can provide you with the answers you seek. Every time someone has given you an answer you question it and then want us to provide evidence for it. That is not what we are here for. If you cannot accept the things that we are trying to teach you, then this forum is not for you.
Drakkith said:Please, don't apologize to me or try to say it's just because you don't speak the language, or whatever. This has nothing to do with the lingo or anything else like that, but simply that you cannot accept what doesn't make sense to you. If so, then fine. So be it. But instead of coming here and trying to make us see your point of view, have you tried picking up a book? Or going to wikipedia? Or taking a class? Or anything else like that? I have several books on things like Quantum Physics and Relativity and such and they usually explain very well why exactly everything is the way it is and also provide the evidence for it.
Drakkith said:I have NO problem if you want to learn and ask questions here. Thats fine. But if you just tell us that we are wrong (Yes, that's what you have been doing this whole time) then we aren't going to help you.
This makes sense as to how it could be concluded. Personally, I feel this is still a HUGE assumption... so I leave it open as surely possible... but currently see no reason to use that as a reason to aim my focus to the idea of elementary, because infinity is admittedly mis-understood/not agreed upon completely.
