The thought that actual experiments could determine the existence of matter we cannot see or feel seems unreal, but physicist Latham Boyle went there. What makes this particular (hypothetical) type of neutrino so intriguing is that it supposedly behaves like dark matter, and if it can be detected, minds will be blown. That something is a subatomic particle known as a neutrino. A new theory suggests the universe we live in has a sort of anti-universe running backwards in time, and it only gets weirder from there, because its existence could mean something floating around in this universe would make it possible to detect dark matter. This goes beyond just a mirror universe - try an anti-universe. Is there such a thing as a mirror universe, and, if there is, what would we see in the mirror?
