In this week’s QA, Fraser talks about how aliens might be testing our morality, traveling faster than light to go back in time, and alternatives to the Big Bang Theory.

Fraser Cain and Isaac Arthur team up again to bring you another epic collaboration. This time, it’s a 2-part series of construction tips from an engineer from a Type 2 Civilization. In this episode, we harvest helium 3, mine the asteroids, and rearrange the Solar System.

In this week’s QA, Fraser talks about capturing comets, finding Lagrange Points around black holes, and what would happen if you crashed a whole lot of oxygen into the Sun.

Cosmologists tell us that the Universe is flat. It sure feels like 3-dimensions. What does this even mean, and how do we know it’s true?

Owning land here on Earth is nice and legal. But what about a plot of land on the Moon or Mars? When can I buy some ice on Europa?

The Big Bang was a tremendous theory, but it had a few problems. In 1980 Alan Guth developed the revolutionary theory of cosmic inflation, and astronomers have been looking for evidence to this day.

The Sun uses its enormous mass to crush hydrogen into fusion, releasing enormous energy. How long will it be until we’ve got this energy source for Earth?

In this week’s QA, Fraser proposes ways to destroy the Milky Way, wonders what might happen if a warp drive ship passes through a planet, and how you could keep a galaxy alive forever.
