Every now and then random people in the world go bat-guana crazy about something, whether it’s about a Big Foot sighting, or believing that a trust-fund billionaire troll-bot will govern for anyone other than other billionaires, or evidence of extraterrestrials. This latter went big in 2016, moving from cow-probing theory-spinning abductees to legitimate astronomers and physicists who tried really, really hard not to sound like they were talking about E.T.
However they tried to dress it up, it was ridiculous. A star, KIC 8462852 (now known as Tabby’s Star), was showing behaviour they didn’t recognise, and the cry of “ALIENS” reverberated around the internet. Sound like a familiar argument?
In fact, the probability of contact with extraterrestrial intelligence is so tiny that there is literally no evidence compelling enough to refute the maths. I explain this here.
