does this boggle your mind, or is it just mine? when the outcome of our universe comes, whether it be the "big crunch" (where all the galaxies are compressd together forming a giant black hole), or whether the galaxies keep moving away from each other, which will result in all the stars dying out making it a cold and dark place. what will happen to the human race? will there be nothing? someone please help me understand this..

That is billions of years away and by that time we will have evolved beyond the need for physical existence.

It has been known for some time that the Universe is expanding. This lead to the question, will it eventually slow down, stop, and then begin to contract(the big crunch)? Or will it just keep on expanding forever?
Astronomers have recently discovered that, not only is the Universe expanding, but that the rate of expansion is accelerating! At present, there is no known explanation for why this should be happening. With all the gravity containing within it, we would intuit that it would eventually slow and contract. But that is not the case. Not only is it not slowing, the rate of expansion is accelerating. At this time, we can only speculate about why this is so. Some have postulated the existence of some form of matter that we do not yet know about or understand, and that this matter(often referred to as 'dark matter') is exerting some sort of repelling force that is counteracting the gravitational force that we know exists.
Whatever the reason, the expansion of the Universe IS accelerating. This suggests that there will never be a 'big crunch', but that the Universe will expand forever. We don't need to worry about this much though. The Universe won't expand enough for anyone to begin to notice for at least a few 100 million years.

Long before the Universe dies, our sun will exhaust its hydrogen supply and be extinguished. Unless humans (if you mean earthlings) have discovered the means of space travel at speeds approaching that of light or have overcome the laws of physics in order to emigrate to distant planets which may support life, while being unpopulated, our race will not survive the extinction of the sun. Whether or not the Universe's fate is eternal expansion as you describe it or collapse is apparently dependent upon the amount of so-called "dark matter" present in the cosmos: the greater its quantity the more likely the great crunch will transpire.

Im not sure if ill help you understand better but ill tell you what i think.
Im pretty sure that the universe will end the Big Crunch style. I dont know why and i definitely dont know when, but its the most reasonabele theory, in my opinion because if the Universe keeps expanding, i dont think itll end it will just get bigger..

know one knows, christians don't know the whole truth, atheist don't know the whole truth, so basically what ever you want to happen is the truth b/c they've already proved the first second of the evolution theory wrong. and unless you have faith (by your question I'm asuming not) then you cant be a christian. So believe what you want that's the only choice you have left!

I think we're doomed either way, but we might not even last that long anyway. The Earth will be long gone before either one occurs.
This will explain a lot

The human race will be gone eons before that happens, so don't worry about it.
