Ep. 145: Interstellar Travel
In science fiction it’s easy to hop into your spaceship and blast off for other stars. But the true distances between stars, and the limits of relativity make interstellar travel almost impossible with our current technology. What would it really take to travel from star to star, exploring the galaxy?
Questions Show: Imaging Extrasolar Planets, Infinite Universe, Inside a Black Hole
What will we eventually be able to see on extrasolar planets? What does an infinite Universe mean? And what’s down there, inside a black hole?

Ep. 144: Space Elevators
If you want to travel into the Solar System, you have to get off the Earth. Traditionally, that meant blasting off in a rocket. But there’s another strategy for escaping the Earth’s gravity. Climb to the top of an extremely tall tower, and just jump away. That’s the idea behind space elevators. Theoretically possible, but practically unfeasible, space elevators have gotten new life thanks to new, super strong materials.
