That's what Hubble can do for us. It can tell us whether the universe is expanding forever or if one day it's going to come back together.

Hubble knows there is interesting stuff out there, but Hubble isn't quite big enough.

I wondered had I really oversold the Hubble. I have to admit that, since, I have been convinced that I didn't.

For almost a century, the Universe has been known to be expanding as a consequence of the Big Bang about 14 billion years ago. However, the discovery that this expansion is accelerating is astounding. If the expansion will continue to speed up, the Universe will end in ice.

When my father died, those years when he was working on the Hubble came back to me, and it seemed fitting to imagine him as having somehow merged with the large mystery that the universe represents.

This is the way the world ends, not with a bang, but a whimper.

If the universe is running down like a clock, the clock must have been wound up at a date which we could name if we knew it. The world, if it is to have an end in time, must have had a beginning in time.

I think the end is endless. It's either a big black hole or a big white light or both together. But it's totally meaningless, because even if someone would explain it, I wouldn't understand it.

When we see what the universe has to show us, we can go no further.

Everything has an end.
