One might say science is the sum total of our knowledge of the universe, the great library of the known, but the practice of science happens at the border between the known and the unknown. Standing on the shoulders of giants, we peer into the darkness with eyes opened not in fear but in wonder.

Don't undermine the science just because you don't like the economics. That's a dangerous slope, because the problem of course is you're not undermining just that, you're undermining the basis of rational decision-making in society.

When you fall into a black hole you will be literally spaghettified.

At every stage of understanding the universe better, the benefits to civilisation have been immeasurable. None of those big leaps were made with us knowing what was going to happen.

[The 1975 Chase Econometrics] showed that for every one dollar spent on Apollo, 14 came back into the U.S. economy.

The story of the universe finally comes to an end. For the first time in its life, the universe will be permanent and unchanging. Entropy finally stops increasing because the cosmos cannot get any more disordered. Nothing happens, and it keeps not happening, forever. It's what's known as the heat-death of the universe. An era when the cosmos will remain vast and cold and desolate for the rest of time the arrow of time has simply ceased to exist. It's an inescapable fact of the universe written into the fundamental laws of physics, the entire cosmos will die.
