Science is not perfect. It's often misused; it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.

We live on a mote of dust suspended in a sunbeam

Every thinking person fears nuclear war, and every technological state plans for it. Everyone knows it is madness, and every nation has an excuse

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

The price we pay for anticipation of the future is anxiety about it

The cosmos is all there is, all there ever was, and all there ever will be.

We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.
