No, NASA did not discover a parallel universe where time runs backwards
“Have you heard that a NASA particle detector experiment discovered a parallel universe where time runs backwards? It’s all over social media, mostly with people making jokes questioning what else 2020 has in store for us, but it also seems to have piqued a lot of folks’ interest. I’ve had many queries asking me if the story is true. Is it? Quick answer: No. Longer answer: No, it isn’t. More detailed answer: Well, this’ll take a sec to explain. But the bottom line is this particle detector did find something really strange, but it’s not clear what it is.”
