- What happens to the helium formed in the sun?
- The Moon and Sun are the same apparent size in the sky. The Moon is moving away from us at 3.8 centimeters/year. Isn't it improbable that we live in an epoch in which they appear the same size in the sky?
- Wait, I'm still confused why information can't travel faster than the speed of light.
- How did a transit of Venus provide astronomers with the first measurement of the Earth-Sun distance?
