The tantalizing possibility of a sci-fi-style warp drive is right on the edge of known physics. The physics of general relativity seem to allow it, but other physics just gets in the way. What are the challenges we would have to face when we build one, and what are the benefits?
0:00 Intro
1:54 Breaking the Speed of Light
7:41 Life in the Warp Bubble
12:19 The Energy Conditions
18:02 Warp Factor 9
24:17 Outro

What’s floating around in space between all the stuff? Are there any truly empty places in the universe? What is the “fabric” of spacetime? I discuss these questions and more in today’s Ask a Spaceman!
Keep those questions about space, science, astronomy, astrophysics, and cosmology coming to #AskASpaceman for COMPLETE KNOWLEDGE OF TIME AND SPACE!")
