Scientists may have found what is believed to be evidence of the concept of a “twin universe” also born during the Big Bang.

In a recent experiment, NASA’s team of scientists found high energy particles which seemed to come “up” out of Earth, the Daily Star reported.

“We’re left with the most exciting or most boring possibilities,” said Ibrahim Safa, one of the scientists who worked on the experiment as quoted by the Daily Star .

The experiment was done to identify high energy particles using NASA’s Antarctic Impulsive Transient Antenna (ANITA), a balloon that can carry delicate electronic antennas above the frozen wastes of Antarctica.

ANITA reached a height where there was next to no radio noise to distort the findings owing to the frigid air provided the perfect environment.

At that height, there is a constant “wind’ of high-energy particles coming down from space. The low energy particles, neutrinos can pass through without interacting with the substance of our planet at all. High energy particles on the other end are stopped by the solid matter of Earth according to a New Scientist report.

According to this, the high-energy particles detected by the device can only come “down” from space. However, the particles detected by ANITA seem to be travelling up.

This indicates that the particles are travelling back in time suggesting the existence of a parallel universe that travels back in time.

Principal ANITA investigator Peter Gorham, of the University of Hawaii, said that the only way for a particle to behave this way is if it had changed its nature before entering the Earth and then changed back again, the report said.

Although several news outlets have already jumped to conclusions penning down sensational titles claiming that parallel universes have been found, the truth is far from that.

The idea that other universes similar to ours exist is nothing new. The multiverse theory has been on for several decades and sci-fi lovers have known about the concept for over 50 years.

In fact, back in the 1950s, a quantum scientist called Erwin Schrödinger suggested that there could be other multiverses out there, although the idea at the time sounded a bit absurd. However, fast forward half a century and you have new technology and new methods that help us peer deeper into the universe than ever before.

Now, cosmic ray detectors may just have come across a set of particles that may very well come from a cosmos different to ours, where, among other things, time as we know it runs backward.

In Antarctica, NASA has set up an experiment called ANITA, which is short for Antarctic Impulsive Transient Antenna. Essentially, it is a massive balloon that transports a set of extremely sensible antennas high above the Antarctic frozen landscape. There, at higher altitudes, the antennas are free from radio noise and distortions that may interrupt their search.

The antennas strapped to the gigantic balloon look from high-energy particles that originate deep in outer space, and some of these particles are millions of times more powerful than anything we are able to produce here on Earth.

Certain particles, like neutrinos, can “transit” through our planet, avoiding interacting with the matter that makes up Earth. However, scientists have found that higher energy articles are essentially met with a wall when struck against the solid matter that makes up Earth.
