Science is not there for you to cherry pick ... You can decide whether or not to believe in it but that doesn’t change the reality of an emergent scientific truth.

During the 1970s and 1980s, the popular television soap opera As The World Turns portrayed sunrise during the opening credits and sunset during the closing credits... The soap-opera sunrise showed the sun moving toward the left as it rose rather than to the right. They obviously had gotten a piece of film showing a sunset and played it in reverse... Had they called their local astrophysicists, any one of us might have recommended that if they needed to save money, they could have shown the sunset in a mirror before they showed it running backward.

The only accounting we had of the origins and the structure of nature was Biblical Genesis.

I don't require that the main guest [of StarTalk] have any science knowledge or background at all. It's just, I have a conversation with them, it's long and winding, and we find out what parts of what we learn about the person lend themselves to further scientific discussion with an expert who is brought into the studio. So that's how that comes together.

But my vote for Venus's most peculiar feature is the presence of craters that are all relatively young and uniformly distributed over its surface. This innocuous-sounding feature implicates a single planetwide catastrophe that reset the cratering clock... turning Venus's entire surface into the American automotive dream-a totally paved planet.

I've accomplished enough in life so that I do not fear death.
