Felix Baumgartner's supersonic feat of high-altitude skydiving may be more than just an impressive accomplishment. Is it a signpost on the way to a future in which we are all Baumgartners?
Hosts Phil Bowermaster and Stephen Gordon discuss how balloons in space, cardboard bicycles, underground parks, and other developments show us a world of nearly limitless possibilities: one in which our own amazing feats may be limited only by...our own imaginations.
Plus: Scientific proof that we're living in a computer simulation?
And: A voyage to Alpha Centauri.
