In some scientific beliefs, the possibility exists that a parallel universe coincides with our own. An experiment in Antarctica may have yielded results that suggest there’s at least an alternate reality out there or more.
The Antarctica Impulsive Transient Antenna (ANITA) experiment, which is a collaboration of several universities and funded by National Aeronautics and Space Administration (NASA), is designed to detect and study high-energy particles. Without going into too much detail, it basically involves flying a helium balloon high above the Antarctic ice sheet and suspending radio antennas from the balloon to record radio pulses.
But while scientists behind the experiment anticipated pulses coming from outer space, they were surprised to find pulses, along with the neutrinos producing these pulses, coming from the ground.
Conventional understanding of physics has been unable so far to explain the phenomenon, which led to some to hypothesize that a universe opposite to ours could explain what’s otherwise seemingly impossible.
Imagine a different universe in which time goes backwards and whose particles have opposing charges as ours. Perhaps that’s where those odd signals came from. A parallel universe would be hard to prove, given that humanity’s present-day technology can only observe within the confines of our own universe, not beyond it.
Others are pointing towards undiscovered physics that has yet to become part of the Standard Model of particle physics. Or, it’s also possible the experiment has made an error, and further testing may prove that to be the case. Nevertheless, it’s still fun to wonder about the possibilities.
