Several Star Trek series visit the Mirror Universe at some point, but The Next Generation isn't one of them. That's not an accident, either.

Similarly, our universe differs from its mirror image. The weak force—the force that’s responsible for radioactive decay—is felt only by left-handed particles.

In looking-glass world, Alice finds all logic turned on its head: People run in order to stay in place, and they celebrate “un-birthdays” on all the days they weren’t born. Similarly, our universe ...

As Higgs Chair of Theoretical Physics at the University of Edinburgh Neil Turok explains in an essay for The Conversation, there could be a "mirror" universe that existed before the Big Bang and ...

Mirror Mirror To test if gravitational waves from black hole mergers do demonstrate a mirror-symmetry-breaking handedness, Bustillo and colleagues measured the polarization of gravitational waves ...

For this picture to be true, we don’t need the mirror universe to be real in the classical sense (just as your image in a mirror isn’t real). Quantum theory, which rules the microcosmos of atoms and ...

Our mirror hypothesis restores the symmetry of the universe. When you look in a mirror, you see your mirror image behind it: if you are left-handed, the image is right-handed and vice versa.
