Did NASA Just Detect a Time-Reversing ‘Anti-Universe’ Over Antarctica?

Did scientists detect evidence for an Anti-Universe, one where time flows backwards? Or is it an overreach into unsupportable hype? I explore the data that led scientists to make claims about ghostly neutrinos that are their own anti-particles. How do scientists interpret data like these and how do physicists reveal the hidden symmetries of nature?

Stange signals were seen in recent years by a NASA-funded radio telescope flown aloft over Antarctica by a giant helium filled balloon. The device, called the Antarctic Impulsive Transient Antenna (ANITA), detects radio signals produced when high-energy particles coming from cosmic sources smash into earth’s atmosphere. Some radio signals waves skim the Earth before being detected by ANITA, and others reflect off the ice. ANITA can tell the difference and some claim their odd behavior are indicative of signals traveling backwards in time. Or are there other interpretatisn? Found out in this video!
