These high-energy particles are a million times more powerful than anything we can create here on Earth
Nasa scientists have detected evidence of a parallel universe, right next to ours, where all the rules of physics seem to be operating in reverse.
An experiment in the frozen wastes of Antarctica has revealed evidence of a universe born in the same Big Bang as ours – but with rules of physics that are completely the opposite
In the theory of parallel universes, when the Big Bang happened, two universes were formed. Although it remains a mystery, it's a popular concept in films and TV series.
In a report by the UK-based tabloid newspaper the Daily Star, a cosmic ray detection experiment conducted by several Nasa scientists found particles that might be from outside our own universe.
The group of experts was working with Nasa's Antarctic Impulsive Transient Antenna (ANITA).
They used a giant balloon to haul the device high above Antarctica, where there is cold, dry air, which provides the excellent condition to use it as there is little to no radio noise that could distort its findings.
ANITA is an instrument that detects ultra-high energy cosmic-ray neutrinos.
These high-energy particles are a million times more powerful than anything we can create here on Earth, and these neutrinos have become a great interest to astrophysicists as they are the only ones that can reach Earth unattenuated.
According to the news outlet, low-energy neutrinos can pass by our planet with no problem, barely interacting with anything.
Nevertheless, high-energy particles will be stopped by our planet's solid matter, which is why these high-energy particles are detected coming "down" from space.
However, the team's ANITA detected a tau neutrino or a heavier particle coming from "up" out of the Earth in 2016, which means that these particles are traveling back in time and could be evidence of a parallel universe.
The bizarre phenomenon was reported by the Nasa scientists, led by Peter Gorham, an experimental particle physicist from the University of Hawaii, as well as the principal investigator of the ANITA.
Even the discovery of the tau neutrino happened by accident, as Gorham and his team decided to investigate signals that have been dismissed as noise in the first two flights of the device, as noted by New Scientist.
