NASA scientists are claiming they detected a parallel universe where the rules of physics are the opposite of this universe.

The reported discovery was made while NASA scientists were working on an experiment in Antarctica to detect cosmic rays. The scientists noted they found particles that could stem from a parallel universe that was also formed during the Big Bang. NASA used an antenna named ANITA (Antarctic Impulsive Transient Antenna) via a giant balloon to detect “high-energy particles” that only be detected coming down from space. However, ANITA reportedly discovered a heavier particle that comes from “up” out of the Earth. The findings from the NASA scientists are saying the particle is traveling backward in time, which suggests a parallel universe. Scientist Ibrahim Safa spoke on the experiment and the results, saying, “We’re left with the most exciting or most boring possibilities.”
