Every time you wink the stars move.

At whose sight all the stars hide their diminish'd heads.

God is not worn out running the galaxy. He's not taxed at all guiding every dust particle all the time.

In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down.

for the fluctuations in the background. However, within a few years we should know whether we can believe that we live in a universe that is completely self-contained and without beginning or end.

Eventually, however, the star will run out of its hydrogen and other nuclear fuels. Paradoxically, the more fuel a star starts off with, the sooner it runs out. This is because the more massive the star is, the hotter it needs to be to balance its gravitational attraction.

You can call the universe many things — awesome, beautiful, violent — but one thing you can't call it is cramped.

the universe is not infinite in space, but neither does space have any boundary.

If information is lost in macroscopic black holes it should also be lost in processes in which microscopic, virtual black holes appear because of quantum fluctuations of the metric. One could imagine that particles and information could fall into these holes and get lost. Maybe that is where all those odd socks went.

We are all of us stars, and we deserve to twinkle.

I believe that everyone, regardless of their beliefs, deserves the dignity of being called by their name.

Even Hubble hasn't found yet the end of this universe, and we don't know that it has any end.
