The concept of a parallel universe has been around since the early 1960s because of sci-fi TV shows, comics, and imaginary movies, but now, the concept is no longer a concept.

A cosmic ray detection experiment has found particles that could be from a parallel universe that was born with our universe in the Big Bang.

Experts used a giant balloon to carry NASA’s Antarctic Impulsive Transient Antenna, or ANITA, high above Antarctica, where the frigid dry air provided the perfect environment with little to no radio noise to distort what it found.

A constant wind of high-energy particles constantly arrives on our planet from the space outside our world.

These low-energy, subatomic neutrinos with a mass that is close to nil are capable of passing through our planet, but higher-energy objects are stopped by the solid matters that are present on our planet.

Keeping that in mind, this also means that high-energy particles can only be detected when they are coming down from outer space.

However, the team of ANITA detected much heavier particles, which are known as tau neutrinos, which come up out of the Earth.

The finding implies that these particles are actually traveling backwards in time.

Woah, let’s take a deep breath first.

Okay, let’s continue.

That finding suggests that there is a possibility of having a parallel universe.

Peter Gorham, the Principal ANITA Investigator, who is also 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 it passed through the Earth and then back again.

Gorham, who is a lead author on a Cornell University paper, said that he and his fellow researchers had seen a number of these events, which they call should be impossible to occur.

Not only that, Dr. Gorham said:

Not everyone was comfortable with the hypothesis.

Here is a simpler explanation for this nearly impossible phenomenon.

So around 13.8 billion years ago, the Big Bang occurred, and when our universe was created, another was formed.

Ours run forward in time, but the other one runs reverse with time going backward.

There is no proof for this, but the fact that they found particles in such way opens a new world of possibilities about the fact that there are 2 versions of us or something running back in time instead of going forward.
