Parth G's video: Parallel Universe: Has NASA Really Discovered One and Does Time Run Backwards In It

Has NASA found a parallel universe where time runs backwards? Hey guys, I'm back with another video. I'm on a roll, I've posted weekly for 3 weeks in a row now! Pretty proud of myself lol. In this video, I wanted to address the stories that have been going around regarding the discovery of parallel universes. These stories claim that the ANtarctic Impulsive Transient Antenna (ANITA) that is partially funded by NASA, has found evidence for the existence of parallel universes. Unfortunately, this is not really what's happening here. Basically, ANITA is a large balloon about 35ish km above the surface of the Earth. As its name suggests, it's situated over Antarctica. It is a detector designed to look for particles known as neutrinos, coming from outer space. Now normally, neutrinos are very unreactive particles, passing through atoms very easily. In fact, physicists estimate that there are millions of neutrinos passing through every square centimetre of our skin, every second. However, if the neutrinos have high enough energies, then they do interact with matter. Instead of passing straight through everything, they smash into atoms. This collision produces particles that ANITA detects. The types of particles produced tells ANITA that a neutrino must have generated them, and the direction in which they move tell ANITA something about the direction in which the neutrino would have been moving before the collision occurred in the first place. Now ANITA was put up above Antarctica to study neutrinos coming from high-energy events occurring in outer space. And it's doing that brilliantly. However, it did also spot a couple of neutrinos that seemed to be coming from below - through the Earth, and up to ANITA. This is highly unusual. High-energy neutrinos, which is what ANITA is calibrated to look for, are highly unlikely to come all the way through the Earth and reach the other side. So once scientists confirmed that these measurements were not due to some sort of error in the technology or experimental method and setup, they had to find a way to explain them. One hypothesis suggested that there was a large Neutrino source on the other side of the Earth, emitting lots of high-energy neutrinos. If this were the case, then it would be reasonable for a couple of them to make it all the way through the Earth and be detected by ANITA. However, another neutrino observatory in Antarctica, the IceCube Neutrino Observatory (run by CERN), has found that this is not the case. From what I can tell, every possible explanation based on physics that we already know about, has been found to be untrue. (I am not 100% sure about this, so please do check the sources I will link below). But if that is the case, then scientists have to delve into the realm of new physics. One possible explanation of this is that a parallel universe exists where time runs backwards and these neutrinos coming through the Earth are just neutrinos from outer space running backwards in time. However, this hypothesis is just that - a hypothesis. It's not thoroughly developed, and it's certainly not the only explanation for what's going on. Most importantly, the discovery of these anomalous neutrinos is not automatically evidence for the existence of parallel universes. Unfortunately though, the idea of a parallel universe is exciting to read about, so it's been making the headlines - and this is another case of a scientific discovery being blown out of both context, and proportion.
