the universe is getting larger, and could eventually be destroyed. this is becasue as the universe expands, planets and such get further apart. this means that there will be more dpace in between them so things will get colder. this could mean that things like our Sun could freeze up (thats if it hasnt already blown up like it will in 10million years). the only way of stopping this, is if all the matter in the universe produces enough gravitational strength to stop the universe expanding. this would then casue it to get smaler and go into a small ball like it was before the big bang either way, we're screwed lol. but it wont happen for millions, maybe billions of years so dont worry :wink:
