ANITA Antarctic Hang Test/University of Hawai'i at Manoa.

In what may be called a rejig from sci-fi TV shows and comics of the early 1960s, a cosmic ray detection experiment has found particles that could be from a parallel realm that also was born in the Big Bang, the Daily Star reported.

The experts, in an experiment being carried out in Antarctica, used a giant balloon to carry NASA’s Antarctic Impulsive Transient Antenna, or ANITA, high above Antarctica, where there would be no radio noise to distort its findings.

According to Wionews, a constant “wind” of high-energy particles, however, constantly arrived on Earth from outer space.

The high-energy particles can only be detected coming “down” from space, but the team’s ANITA detected heavier particles, so-called tau neutrinos, which come “up” out of the Earth.

The finding implies that these particles are actually traveling backward in time, suggesting evidence of a parallel universe.

Not everyone, however, was comfortable with the hypothesis.

"The simplest explanation for the phenomenon is that at the moment of the Big Bang 13.8 billion years ago, two universes were formed — ours and one that from our perspective is running in reverse with time going backwar," the report said.

And if there are any inhabitants of a possible parallel universe, they’d consider this universe the backward one.

Hypothesis by researchers

Principal ANITA investigator Peter Gorham, an experimental particle physicist at the University of Hawaii, suggested that the only way the tau neutrino could behave that way is if it changed into a different type of particle before passing through the Earth and then back again.

Gorham, lead author on a Cornell University paper describing the odd phenomenon, noted that he and his fellow researchers had seen several of these “impossible events,” which some were skeptical about.

“Not everyone was comfortable with the hypothesis,” he told New Scientist.

The simplest explanation for the phenomenon is that at the moment of the Big Bang 13.8 billion years ago, two universes were formed — ours and one that from our perspective is running in reverse with time going backward.

Of course, if there are any inhabitants of apossible parallel universe, they’d consider us the backward ones.

“We’re left with the most exciting or most boring possibilities,” said Ibrahim Safa, who also worked on the experiment.

Arguing for a multiverse

There is a large suite of scientific evidence that supports the picture of the expanding Universe and the Big Bang. The entire mass-energy of the Universe was released in an event lasting less than 10^-30 seconds in duration; the most energetic thing ever to occur in our Universe's history. NASA / GSFC.

According to Space, around 13.7 billion years ago, simply speaking, everything we know of in the cosmos was an infinitesimal singularity. Then, according to the Big Bang theory, some unknown trigger caused it to expand and inflate in three-dimensional space. As the immense energy of this initial expansion cooled, light began to shine through. Eventually, the small particles began to form into the larger pieces of matter we know today, such as galaxies, stars and planets.

One big question with this theory is: are we the only universe out there? With our current technology, we are limited to observations within this universe because the universe is curved and we are inside the fishbowl, unable to see the outside of it (if there is an outside.)
