I know, I know - time travel is everyone's favorite dream. Whether in sci-fi movies (Tenet, Primer), TV shows (Star Trek, Doctor Who), or books (End of Eternity, Kindred), we've all dreamed of time-traveling to the future, of partaking in a completely-changed version of our universe. Unfortunately, though, today's episode is here to crush your hopes and dreams: we'll talk about why time travel is (mostly) a bust, and why most common time travel solutions (wormholes, Einstein-Rosen bridges, etc) are unlikely to occur. So grab your tissues, get grounded on Earth, and get ready to have a good cry - let's talk about the truth behind time travel today.
