Even more fascinating, it’s believed that the alternate realm is a true mirror of our own—with time going backward, left being right, positive being negative. “Not everyone was comfortable with the hypothesis,” says Peter Gorham, an experimental particle physicist and lead investigator for NASA’s Antarctic Impulsive Transient Antenna. While it sounds wild, this explanation is actually the simplest, though it has been met with skepticism. Researcher Ibrahim Safa explains plainly, “We’re left with the most exciting or most boring possibilities.” Read more at New Scientist.
