A recent article on Space.com caught our attention, so this episode we're talking with the author of that article, Our Milky Way Will Crash into a Neighbor Galaxy Sooner Than You Think , Dr. Michael Wall . He's a senior writer for Space.com and also author of the book Out There: A Scientific Guide to Alien Life, Antimatter, and Human Space Travel (For the Cosmically Curious) , so you know he had a lot to talk about with Dean Regas and Anna Hehman.
