We still don't have proof of intelligent life beyond that on Earth.

  • One of the biggest questions is whether we are alone in the universe — could there be other intelligent life, besides us, out there? Currently, we don't have any evidence aliens exist.
  • There may have been a chance for a civilization to start billions of years before life began on Earth — one that is far more advanced, technologically speaking, than us. However, they're not making it very obvious. We have no proof of this.
  • If such an advanced civilization exists, though, it probably relies on solar energy to fuels its everyday activities.

Hey Bill Nye! What Will Happen to Earth as the Moon Drifts Away from It?

Farewell Moon, we barely knew you. Bill Nye knows the Moon is moving away from Earth 1.48 inches per year. Will it keep drifting further away, and what happens to Earth when it does?

No matter what happens to you in life, there’s one constant you can always depend on: that when night falls, the Moon will be there in the sky. Dun-dun-dun: or can you? Chris and Brendan have submitted a question to Bill Nye after discovering that the Moon is moving away from Earth 1.48 inches per year. Will it keep drifting further away, and what happens to Earth when it does?
