Cheap Astronomy - Dear CA Ep. 127: Mystery Physics

Hosted by Steve Nerlich. Well… Cheap Astronomy confirms some mysteries are still mysteries! Dear Cheap Astronomy – Is warp drive looking any more possible? Well, no, insofar as it looks about as possible as it ever did, which is to say, it's probably impossible, but at the same time, it's best to never say never. As we've covered before, the nature of space-time precludes the possibility of faster than light travel simply because light travels as fast as it is possible to travel in space-time.   Dear Cheap Astronomy – What is X-17? X-17 is a mysterious and somewhat hypothetical particle. Somewhat hypothetical means there is a bit of evidence for its existence, although it's more a case of there being evidence of something unusual, rather than definitive evidence of a new particle that does something unusual.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
