I have yet to see a successful prediction about the physical world that was inferred or extrapolated from the content of any religions document.

Curiously, light-loving green plants reject the Sun's green light, reflecting it back at you, which is why they look green.

A supernova is one of the most powerful explosions in the universe. It's so luminous, it can be seen across billions of light years. It releases as much energy in an instant as our sun will produce over its 10-billion-year lifetime.

My only hope is that every other alien civilization isn't doing exactly what we are doing because then everybody would be listening, nobody would be receiving, and we would collectively conclude that there is no other intelligent life in the universe.

Revelation replaced investigation.

A successful day for me is when I teach people something. They become enlightened by an idea and learn how to think about it, so that later on when someone says, "Tell me about x, y, z," they don't have to say, "I know this because Tyson told me." No, they'll say, "Here's why it's true because I know and understand it."

It is in the best interests of civilization and our economy and our nation to understand what objective truths are as revealed by the methods and tools of science.
