Q&A 146: Could We Even Comprehend Aliens... as Aliens? And More..

In this week's questions show, I explain why we'd be able to recognize aliens, even if they were vastly more technologically advanced than us. Why I don't do any promotional ads on my videos, and if we have any examples of energy turning into matter.
