Exsistance before the speed of light hits- question for you.

Click For Summary

Discussion Overview

The discussion revolves around the philosophical and physical implications of existence in relation to the speed of light. Participants explore whether objects exist independently of light and how our perception of existence is influenced by light and other senses. The scope includes philosophical inquiries, conceptual clarifications, and some technical reasoning related to physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the validity of existence before light interacts with an object, pondering if an object exists if it cannot be seen.
  • Another participant argues that existence is independent of light, using the example of throwing a baseball in the dark to illustrate that something can exist even if it is not visible.
  • A different viewpoint suggests that existence can be considered on a quantum level, proposing that the universe can expand faster than the speed of light, implying that existence may precede light's arrival.
  • Some participants discuss the limitations of self-study in physics and express a desire for more structured learning and guidance from professors.
  • Concerns are raised about the oversimplification of complex physics concepts and the importance of using proper academic resources for learning.
  • One participant challenges the assumption that light is the only means of knowing existence, emphasizing that other senses also contribute to our understanding of reality.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the relationship between light and existence, with no consensus reached on the philosophical implications of the question. The discussion remains unresolved, with differing opinions on whether existence is contingent upon light.

Contextual Notes

Some participants note the limitations of their understanding and the need for further exploration of physics to address philosophical questions. There is also mention of the potential for confusion between physics and philosophy in this context.

Who May Find This Useful

This discussion may be of interest to individuals exploring the intersections of philosophy and physics, particularly those curious about the nature of existence and perception. It may also appeal to self-learners in the fields of physics and cosmology seeking to deepen their understanding.

::EDIT::

crap, i think i posted this in the wrong place...i think. I am reposting it in general physics.

Still new here...cant seem to find the line between physics and philosophy in my question. Pardon me.

(just incase i had it right the first time, here is my post)

(just a tad of back ground so i don't seem completely clueless) as a child, i showed more interest in the arts rather than science and math, so my father, though dissapointed, full nutured my artistic side. This resulted in me attending arts/dance magnet schools, so i was never able to explore or learn indepth about the sciences. I got older and my long desire to be involved in physics/cosmology got the best of me and i began to self study. Though i do mostly understand what is being said and taught, due to the lack of exposure I am still baffled at questions/theories that i read or think about. So please, excuse me if i may seem a tad naive with the question i ask.

While reading and studying about the speed of light, time travel and Einsteins theorys, a question i have seemed to keep me baffled. Everytime i try to figure it out, the artsy philosophy side kicks in and i usually just end up confusing myself.

after much pondering and not coming to a conclusion, I've decided to break down , embarrass myself and ask for help.

This is one of the question that plauges my mind.

Light travels at a set speed, nothing can go faster than light. This i fully understand, but what of the validity of exsistance?

Ok, light is how we know things exsist, light rays bouncing off an object is how we recognize its exsistance. But what about that object before the light rays hit it and bounce off? Does the object still exsist?

Is this situation anything remotely similar (philosophically or not) to going faster than the speed of light?

This question seems like something i should be able to figure out, like the answer is there but I am just not reaching far enough.

Can someone please help me out?

(i may have not explained my question well enough. Its a lot easier to think about when its in your head, but getting it out and trying to make it make sense is a different story. Just let me know if i need to explain more, i will try my best)

Thanks so much!

it really has nothing to do with the philosophy of light because there is a simple explanation. Go into a dark room with a friend and a baseball, throw the baseball at your friend, does it hurt? Of course. Just because you can't see it doesn't mean it doesn't exist. I mean something must have hit your friend :).

We observe things in many different ways, light is only one of them.
 
there can be existence without light... example... what if a black hole is alone in the universe? there is no light being emitted, just extreme gravitical forces. I'm not a physics expert, but philosophy is my thing. I think this is an "easy" answer to your question... since i don't have any real answers, i'll just do my best to try and explain wha i understand... although the true question would still be, could that black hole have ever formed in the first place without some form of light bearing body/material/etc? If you truly wish to find out these answers i'd suggest you get a bit more involved in physics.. it can get fun. It's how i got started, had many philosophical questions, and realized everytime i asked one, i never really received the answers i was looking for. Sometimes you have to search it yourself.

i think he's referring to existence on a quantum universal level... he's almost implying the question of... can anything exist before light gets there? Which can be answered as a yes... since the universe has been seen expanding at faster than the speed of light. I know you're searching for a deeper and more intricate answer, i'll ponder it for a couple nights.
 
This makes sence.
The only physics/astronomy/cosmology I've been involved in is self study. Serious self study. I have and read many published papers, journals, books and even textbooks. Though i guess there is no substitute for hands on learning and help from professors.

Im not in college at the moment, for I am putting that off until I am finnished with my ballet career. (yes, i am a girl :-p ) You only have from when your 16 to about 25 to be a professional dancer...had to take that chance when i could.

What are things i can do to get more involved with above mentioned studies without having to entroll in university? Dont get me wrong, university is 100% in my plans for the near future, but i just don't have the time for full or part time enrollment. What are other things i can do to help with my quest?

Thanks so much.

Textbooks... and none of this paperback barnes and noble/borders crap either. People who do that, in my opinion of course, have terrible understandings of physics. They all seem to have this ability to apply things where they shouldn't be applied and use terms that make no sense in context... etc etc. I mean you get one of these people that think its "so obvious" that you can surpass the speed of light using simple constant acceleration and no matter how much modern physics and equations you toss at them, they will still go back towards the philisophical/incredibly basic view of physics where accelerations just add on forever.

Sorry, just a rant :)

Go to a university and talk to one of the professors and ask them what textbooks to start out with and go basic-> advanced. They will most likely even have the books on hand so you will know exactly what to buy. They do tend to cost a lot of money however... my introductory 3-semester series cost $120.

Please note that cross posting is NOT allowed on here. If you wish this to be a physics question, I will have to delete your thread in the Philosophy forum.

Zz.

Edit: I've merged the two threads and deleted duplicate posts. Still, there may be some strange continuity. Note that if this turns out to be more of a philosophical discussion than a physics issue, it will be moved to the philosophy forum.

Where did you get the idea that " light is how we know things exsist, light rays bouncing off an object is how we recognize its exsistance"?

You can hear things, you can touch them. Vision is ONE sense. It certainly is not the only way we can "know things exist". Even worse, you seem to jump from "know things exist" to "light is what makes things exist"!
