Everything is broken down into what makes it up. Eventually. But does it last forever?

Entropy applies to closed systems. The universe is not a closed system.

Ah, I see what you mean - that because there is no necessary limit to space, then the universe's expansion may continue forever? Is this what you mean?

Because the universe by definition encompasses all the interacting units of the system, so if it is an "open" system in that it is interacting with other universes, then they are, collectively, part of a greater knowable expanse of universes. If we cannot have empirical evidence of other "universes" outside our own, then it is closed in that respect.

Yes matter is infinite. By physics/chemistry/biology laws: Matter can never be destroyed but created.

Yes matter is infinite.

No it is finite.

Is space infinite, is probably what the OP meant.

But what about entropy? Since matter naturally moves to the state of being unorganized (pretty sure that's what entropy is) what will happen when disorganization is complete? Will entropy just stop?


I would think entropy would increase until reaching a point where it remains constant.

Yes but it is interacting with other dimesions like time, which does impact entropy.


Possibly. Though these dimensions may just be other parts of our universe that we don't normally interact with.

Also... where did the other universes come from?

It is infinite, but it is not infinitely dense.

I think matter never disappears it just reforms into different things. It is infinite because even nothing is made of something.

speaking of dimensions... one of my friends who is a physics major tried at some point to explain to me that there is a list of about 8,9,10 (or more) different dimensions acknowledged as facets of our existence/universe... I think he lost me around the time he said there were more than just length, width, and height. The jargon was beyond my vocabulary for the most part so I didn't understand all of it... and that was over a year ago so I don't remember what was said (only that it was in fact said)

From what I know there are currently 11 dimensions believed to be in existence. The eleventh is dealt with in M-Theory.

Here's a video giving a lay description of the first ten.

...>_> you and your videos... and me and my bad internets >_<

again... I'll be getting back to you. can't really afford to stay up all night and wait for the infini download time span between 2-6 b/c of my lame spring break i'm spending studying DX

It(matter)is infinite because even nothing is made of something.

What? How can nothing be made of something when it's nothing. Nothing is nothing, which means it can't be something. Nothing is an idea. So I guess even nothing isn't nothing. 0 is still a number, right? (I'm going to start another topic on that...)So nothing would be impossible.

yes all matter breaks down at a constant rate over time even at the atomic level thats a fact

exactly what i said and 0 doesn't = infinity.

and for anyone out there who is confused what he is saying is that all matter "wants" to reach its lowest possible state of energy

I'm pretty sure that this has been answered, but since nobody contested my post, I will say it again.

So, is matter infinite? Yes and no.

Matter is not infinitely dense, nor is there an infinite amount of matter in the universe. Matter can be divided infinitely.

Get it?

that last part is debatable some people contest that there is a point at which you cant split it apart any more
