Eventually, the Sun will swell to occupy the entire sky as its expansion subsumes the orbit of earth. Earth's surface temperature will rise until it matches the 3,000-degree rarified outer layers of the expanded Sun.... But not to worry. We will surely go extinct for some other reason long before this scenario unfolds.

I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.

I see myself in pop culture. I listen to pop music, I do pop things, and I'm also a scientist.

I love being wrong because that means in that instant, I learned something new that day.

How many times have you heard a person in a workplace say, "I wasn't trained for this!" That's an impossible reaction from a physicist, who would say, instead, "Cool. A problem I've never seen before. Let's see how I can figure out how to solve it!"

God is an ever receding pocket of scientific ignorance.

In five billion years, the sun will expand and engulf our orbit as the charred ember that was once Earth vaporizes. Have a nice day
