The universe will never end. The big crunch has been disproved a long time ago, so don't worry.
In a way - it will end. The only matter left will be Photons, neutrinos, electrons, and positrons and they will fly from place to place, hardly ever encountering each other. Gravitationally, the universe will be be dominated by dark matter, electrons, and positrons...
but if protons don't decay, all matter will decay into iron-56 and form stellar mass objects, cold iron stars. Billions, and trillions, and INCONCEIVABLE amounts of time later - they will collapse and either form black holes or neutron stars. These will be the only black holes/neutron stars left as old ones would of evaporated.


By this era (dark ages/era), and only very diffuse matter remaining, all activity in the universe will have tailed off dramatically (compared with previous eras), with very low energy levels and huge time scales. Electrons and positrons drifting through space will encounter one another and sometimes form positronium atoms. These structures are unstable, however, and their constituent particles must eventually annihilate . Other low-level annihilation events will also take place, but very slowly.

The universe then reaches an extremely low-energy state. But happens after this is speculative. It is possible that a Big Rip event may occur far off into the future. Also, the universe may enter a second inflationary epoch, or, assuming that the current vacuum state is actually false vacuum, the vacuum may decay into a lower-energy state., Finally, the universe may settle into this state forever, achieving true heat death...

Space will end once someone gets a nuke in MW3......

SPACE IS NOT INFINITE!

Something that has existed for a finite time cannot have a infinite amount of space.

as big as you think it is.

TTGx2Pro4You wrote My opinion is kind of cheesy. What I think is that Space does end up somewhere. I believe it ends up in a second dimension where it keeps on going and going and going. So basically everywhere it ends, it comes to a new dimension and keeps on going and going which is INFINITE.

That's weird, I thought we already had a second dimension.

When God made the Universe, Earth and everything else, he is still probably making it, adding new species of life, or as others call it, Aliens. And it never will end. Until you are dead and go up to heaven or hell(depending on what you did during your life, and also I'm NOT a christian)then ask God and see for yourself. Space is just a vast, never ending wasteland, that will never cease to exist. It will stay there forever. And also, the year since the Earth has been made, is a number of years. I say it is BILLIONS years old. But Russians say it's 7400+ and Arabs say it's about 1649, and some say 2011. But some people have other beliefs. What I process in my head is nothing compared to this guy here or Johnny over there. Just believe what you want to believe and don't let that be taken away from you.
Disregard what others say and say this: I'll believe what I want to believe.

So the tables have flipped. I'll ask you. When DOES space end?

I think its generally agreed to be constantly expanding

never said I didn't, but thanks for taking the time I guess?

Well, i think it just goes on and on forever. But thats just me.
