Thread: Matter of The Universe Hypothesis.

Well, im an 8th grader in Advanced Physical Science, and this may be a stupid question , but its been nagging at me for months now.

As im sure you all know the law of conservation states that, "Matter cannot be created nor destroyed." But as i go over this i seem to think. How can that be possible if the big bang created time and space? While i thought this something clicked, and my mind said , "That isnt right." So i go on thinking. Now I have a few ideas as to how this could come to be.

1. A few days ago I saw, "The Universe" on the history channel i believe, and one theory said that , in many many cosmological decades that the universe's matter will start to contract together and eventually become at a molecular level , just extremely dense, and explode as another big bang. So, i have a hypothesis that would say something to the effect of , There has been more than one big bang, But The Matter in the universe cannot be created nor destroyed. so. where did that come from?


2. Another part of this law that I've heard is that matter cannot be created nor destroyed as long as energy remains in the system . So, my thought is perhaps energy somehow from some other, Time Space Continuum , entered ours and therefore created matter. BUT! how that energy was created is a mystery to me.



-Edit- Sorry To the Admins for the mispost. Im new

Yay more pseudoscience/trash! Or just plain stupidity. I'd much prefer it be moved to /trash/ in that case.

Wince.

But as i go over this i seem to think [...]

I doubt that.

How can that be possible if the big bang created time and space? While i thought this something clicked, and my mind said , "That isnt right." So i go on thinking. Now I have a few ideas as to how this could come to be.

Few things. First, the consensus is that the big bang CREATED our present universal laws. This includes entropy.

Second, there are some ideas regarding it being a forever-recurring singularity with no end or beginning (fits thermodynamics just fine).

There has been more than one big bang, But The Matter in the universe cannot be created nor destroyed. so. where did that come from?

That's more of a philosophical question most prefer to answer with "It doesn't require a beginning", so instead it has just been eternally recurring. God anyone? Aharhar.

Another part of this law that I've heard is that matter cannot be created nor destroyed as long as energy remains in the system. So, my thought is perhaps energy somehow from some other, Time Space Continuum , entered ours and therefore created matter. BUT! how that energy was created is a mystery to me.

...You, good sir, need to consider a career in bagging groceries. Matter was not created. It has always existed, just in different forms.

How does this foster discussion? The poster is perhaps 13 of 14 years old, so it is only natural that s/he'll lack a lot of knowledge. It is possible to point out mistakes without resorting to sarcasm or mockery.

Sarcasm or mockery is more effective. Also, are you going to continue to battle me relentlessly EVERYWHERE I POST?

At what? Making new people go away and never come back?

I'm sure you're posting in lots of subforums. I'm replying to you in two. You're the fella with the self-appointed mission to label all the new threads in NH. Sure you don't want a moderator job here?

There is actually a cosmological model which considers this. Each cycle the universe would big bang outwards, and then contract inwards. However, current data suggests that the universe isn't headed for a Big Curnch. The expansion is actually accelerating, so instead we're likely headed for a heat death where everything is the same temperature and no useful work can be extracted anywhere in the universe.

But The Matter in the universe cannot be created nor destroyed. so. where did that come from?

Matter can be turned in to energy, and vice versa. That's that famous [urlhttp://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence]equation[/url] you've probably heard about. In the very early universe, there was only energy. After the universe expanded far enough it cooled and the energy "condensed" into matter like electrons and protons and neutrons to make matter as we know it.

So the better question is where did all the initial energy come from? One guess I read about is that the current universe is the inside of a black hole in another universe. The early energy was matter which had become massive enough to form a black hole. Once the black hole had formed in this parent universe, inside the black hole the space was infinitely stretched to produce our own big bang.

But at this point it's not even a proper hypothesis. Just wild speculation. So feel free to come up with your own wild speculation to explain where it all came from.
