In this week\'s live Questions and Answers show, I explain how a more powerful rocket could reduce the need of a heat shield, if we could detect objects beyond the edge of the observable Universe through their gravity, and what are the largest objects (or spacecraft) that could hang out at a Lagrange Point?
