Haven't heard from that one yet, but what did you mean, "Go cold". Just, disappear, or what?
It's better known as the Big Freeze. It's basically looking at the universe as a whole as one big closed system and as a closed system the second law of thermodynamics applies. So the entropy of the universe will continue to increase and eventually reach a heat death. Of course we are a very long way off from this happening if the theory is correct.
The amount of space around our universe is infinite, although our universe itself is finite. Thanks to our friend dark energy, the universe is expanding outwards perpetually, but most likely not regularly. A Smithsonian magazine article on dark energy I read has some really good information on dark energy.
Second law of Thermal Dynamics states that matter cannot be created nor destroyed. Based on this, we can assume that it has always been here, and what we have we have forever more.
Google antimatter. Also during an atomic explosion the weight of the atoms goes down.
Isn't the universe finite but like infinitely expanding? Idk if i said that right lol.
Like i've heard the theory/metaphor that the universe is like a giant soap bubble...wait i lost my train of thought...dang it i forget where i was going with that...something with how the bubble is expanding? i forget i'm sorry haha
The universe doesn't go on forever, although (technically speaking) there is a theory that the universe "loops" back on itself. It says that if you travel in a straight line on and on, eventually, you would arrive at the same spot because of that loop that goes in every direction.
(@IcyGryphon) "Finite" is a word, as it turns out, just a lesser known one. I asked myself the same question not too long ago.
Isn't the universe finite but like infinitely expanding?
Well, yes, but not infinitely. Scientists are now saying that the universe is expanding slower and slower [url=http://map.gsfc.nasa.gov/universe/uni_expansion.html].
It might be infinite, but I won't call it that; I think its just ever expanding. It might stop expanding eventually.
What do you mean? I can't quite get what you're trying to say. The universe can't expand forever, eventually, the force from the Big Bang will eventually be overcome by the force of gravity.
