How did the Big Bang occur when there was (literally) nothing to cause it?
That's fascinating. So what is the ultimate fate of the universe?
According to current scientific understanding, the ultimate fate of the universe depends on the amount of matter and energy it contains. If there is enough matter, the expansion of the universe will eventually slow down and stop, before collapsing back in on itself in a "Big Crunch." If there is not enough matter, the expansion will continue indefinitely, leading to a "Big Freeze" where the universe becomes too spread out and diffuse for life to continue.
