Recently you may have seen headlines about an "upside-down cosmic ray shower" that could serve as evidence of a parallel universe in which time moves backward.
I truly need an expert to explain this to me like I'm 5, but I'll do my best to break down in elementary school terms what I've read repeatedly: So, a giant balloon was used to carry NASA's Antarctic Impulsive Transient Antenna (aka ANITA) high above.
It seems that researchers were looking for "high-energy particles arriving from space." In the process, they found a high-energy particle "exploding out of the ground." Researchers said this isn't standard and could be a physics phenomenon, which quickly turned into: THERE'S A PARALLEL UNIVERSE WHERE TIME MOVES BACKWARD AND IT'S 100% CONFIRMED.
As the tweet below from a quoted researcher indicates, things were blown out of proportion. Personally, I LOVE all theories regarding aliens, parallel universes, and astrophysics, and so did a lot of folks on Twitter, who fired off these quality jokes about the newly "discovered" parallel universe.
