Light has energy this is true. It can travel to new places.

What is causing the expansion is kind of at the forefront of cosmology. That's the big question. I don't know if it has a limit.

Umm, no universe? I don't know, but there is something called the heat death of the universe. Look up the 5 ages of the universe

You are of no good in science.
Since all you do is answer the questions you think you know because you read something in a book that talked about it, and you dodge all other questions and ideas.
You don't create anything on your own, or opine with your own ideas.

You know science and evolution comes out of discussing about what we don't know, creating creative ideas and opinions using our own logic and imaginative sense.

Stay in history cause science is not for you.

What do you mean? There were two questions I had no answer for: one is at the forefront of physics, and I don't have enough background in cosmology to begin discussing it intelligently. The other one makes no sense. You asked where there is no universe. The definition of where is confined to the universe.

I just wonder how can they be so sure that the universe is expanding at all. And If it's really expanding, it means matter/energy will show up in that new space.
So where does this new energy come from?
Because if the universe is unlimit expanding, then there is unlimited energy in it, created or in such a form that it also expands or multiplies out of.. Nothing.

I also wonder if this energy/matter is not just created upon our universe consciousness awareness/belief that something is there.

Well you think relativity is wrong, so I guess they can't be sure.

sorry my wording was really bad. i didnt mean a plane-ray. what i meant was why would it be infinite on the x, y axis but finite on the z axis

wow this thread has gone way away from the topic question



really? light comes from the nuclear reaction of stars its not a mystery at all

and the universe is expanding fast than light, the prevailing theory is because of dark energy. someone posted a while ago an alternate theory about its because of a quantum vacuum effect





thats not an accurate picture of what the universe probably looks like



this is completely wrong

the universe is flat, but not because of any of that



people found that these supernovas were moving away from us at accelerating rate or something like that

they just won a nobel prize for it, you can google it pretty easily

and are consciousness has nothing to do with the existence of anything. you need to stop watching youtube videos and get away from that idea




as far what is dark energy, its relatively unknown

here's nasa's explanation (or part of it)

"One explanation for dark energy is that it is a property of space. Albert Einstein was the first person to realize that empty space is not nothing. Space has amazing properties, many of which are just beginning to be understood. The first property that Einstein discovered is that it is possible for more space to come into existence. Then one version of Einstein's gravity theory, the version that contains a cosmological constant, makes a second prediction: "empty space" can possess its own energy. Because this energy is a property of space itself, it would not be diluted as space expands. As more space comes into existence, more of this energy-of-space would appear. As a result, this form of energy would cause the Universe to expand faster and faster. Unfortunately, no one understands why the cosmological constant should even be there, much less why it would have exactly the right value to cause the observed acceleration of the Universe. "

also light isnt matter

and the universe almost certainly has finite matter, im pretty sure machs prinicple suggests it and the big bang

as far as the edge of the universe is concerned, when people say "the universe is expanding" it can mean two different things:

the big bang model has a finite universe, and it makes a lot of sense logically. Like it's easier to imagine a finite universe than an infinite one, you just think of the edge of the universe like a black hole where space time is curved backwards and outside of the universe edge is dimensionless

and in an infinite universe, universe expansion just applies to the expansion of matter

but evidence suggests a universe thats flat and an infinite plane. my question is why does the universe being flat suggest its an infinite plane? why cant it be a finite plane?

Oh well that's the biggest salad of non sense I've ever seen in a forum.

Do you actually know anything at all besides random old bytes from here a there that most of them dont even have any evidence?
Can you actually answer to any real questions on your own without jumping throughout quotes spaming no you're wrong?

This is what I get from your post:

No
You're wrong
That's wrong
No
That's not why
Albert Einstein said this: (insert random copy/paste from Albert Einstein delusion, which I can't explain but must be correct because it's Einstein and you know)

No you're wrong
Wrong

Google it (because I have no clue what you're talking about)
No
Light isn't matter
That's not true
No

... And finally a somewhat coherent question nonetheless, which basically is one if the things I've been talking about the whole time.

I'm not replying to any other of the random bytes with 0s and 1s of mojo the dog barking, besides to the question..

It can be finite, what makes you think it is finite?
And how/what limits its end?

You don't know this for sure. But I agree with you.



Ok so why is it flat then?
Denying a theory without an argument is like being blind and try to look at the sun.



Einstein and many others won Nobel prizes too in the past and guess what, they were wrong.



You have absolutely no clue about what you're saying here, dont even try to argue about it.
YouTube videos are not the reason people talk about it, its been known for thousand of years, but not everyone has the sense to understand it correctly, or the open mind to even think about it.
You should learn a little bit if you're gonna try to argue about this, cause to me is like teaching pigs to speak English. It really feels like that. I say "hi" they say "oin".
Already told you I know this from personal experience for a looong time, now keep living in your delusion of reality.



The nada explanation which they can't explain.
But since it was Einstein who thought about it, thats what they serve for you to eat.



Well done.
Everything is not lost.



If matter is finite than what is it filling the constant new space with the expansion of the universe?
Just light? Or is it energy that is also showing up out of nowhere as they say (Einstein)?
All of a sudden... ENERGY!!!



Was this universe formed in its entire space in an instant after the big bang?
Was the space already here before the big bang?
Or has the space expanded after the big bang to a now limited size?

..your finite theory supports one of these I guess.

Also how can you believe the universe is finite, if it all came from the big bang, its all matter and energy and the galaxies are spreading apart?
How can you relate all of this and still defend the idea of being finite?



What do you mean exactly by expansion if matter?
You just said matter was finite. How can it be expanding?
Particles size?
Atoms size?
If matter is expanding dont you think earth would be expanding too, and you and me and everything you see cause its all matter?

Or why is matter expanding only on the edge of the universe and not everywhere else? If this is case.

- See, this is what I keep telling to everyone, you accept what Nobel prizes guys say and what random you read imply, as being true.
When in most situations nine of their theories and concepts about different stuff support each other on their possible co-existence, as in they are contradictory.
And now in the middle of that big mixed salad of banans and strawberries you want to rationalize an answer to your own question.
You need to start thinking for yourself and sont just accept any random quote as truth, try to match it first and make sure it supports all other ideas that you have, if not then deny it and try to reason it.

A book means shit
A Nobel prize means another shit
Einstein smoked weed
Newton was a drunk bastard

k both the last 3 posts were very long lol

i believe that space is always there. and i consider the universe just to be objects that occupy the space. was trying to answer one of the questions =3

another one i think was about why the universe is expanding, which should have an obvious answer
the big bang was an outward explosion.

btw there's no way you can say there's no center to the universe, it exploded from a point

my question is how we know the universe is expanding at an accelerated rate?

All of you stop posting, you don't know shit about cosmology and physics.
