Gee, you're really getting more input now that you moved it to this section.

Unreal. Imagine just how fast we'd have to go to find intelligent life. If the stories about aliens from another galaxy are true, imagine how advanced they must be to get here from there. Maybe our concept of a "lifetime" is just meaningless ot them, and they live millions of years? Mind boggling.

The galaxy is 100000 light years across. The record for hitchhiking this distance is five years, though you don't get to see much along the way.

But at least you know the answer is 42. And hey, if it isn't, there's always the possibility that you aren't asking the right question.

Yeah... the Universe is stranger than you know, and quite possibly stranger than you CAN know.

I study things that are very small. The universe is an infinity of the large and small. Think of atoms, they are mostly empty space. There aren't that many atoms in the whole universe relative to it's size, which means the universe is pretty much made of nothing.

Oh, and dark matter. And vacuum energy.
Cosmology is

I always hear that the universe is constantly expanding due to some unfathomable amount of energy. What happens when that energy is expended? There will be no force to expand any further, but there may be no force to hold it together either. All that expansion would collapse on itself, resulting in one infinitely dense molecule just like before the Big Bang.
