Neil deGrasse Tyson Debunks Santa's Existence, Sends Internet Into Meltdown

Neil deGrasse Tyson was compared to the Grinch after he said Santa would be vaporized into nothingness if he actually traveled at high speed delivering presents around the world.

The astrophysicist, 63, was clearly not in the festive spirit when he broke down what would happen to Santa if he did in fact exist, in a much-criticized tweet.

Tyson said: "For Santa to deliver gifts to all world's Christians in one night requires hypersonic speeds through Earth's lower atmosphere, vaporizing his reindeer and sleigh. Just sayin'."

Tyson's comments went over as well as a Christmas stocking filled with coal with many perceiving the astrophysicist's comments as being Scrooge-like.

British author and journalist James Felton said: "Then how do you explain all these f***ing presents, Neil?"

American MMA brawler Josh Barnett commented: "Next you'll be telling us how it's impossible for Santa to have a bag large enough to carry all those presents.

"Congrats on saying things no one cares about, that don't matter for what seems to be a masturbatory reason. F***ing buffoon."

Associate Professor at Canada's University of Waterloo Emmett Macfarlane posted: "My favourite part of these dumb tweets is that they unscientifically accept the premise that the reindeer and sleigh are *capable of flight*."

Broadcaster Brien Rea added: "Neil deGrinch Tyson. Just sayin'."

YouTuber Uche Nwaneri found himself among a small number of people praising Tyson over his comments.

He said: "Lmao [laugh my a**off] I love this man. He got folks losing they mind because he applied science to mythology (sic). Trolling at lvl [level] 99 real talk."

The tweet about Santa's demise if he were real and traveling at super-fast speeds was one of a series of posts that took aim at the Christmas icon.

In another post shared on Christmas Eve, Tyson said: "Santa doesn't know zoology: Both male and female reindeer grow antlers. But all male reindeer lose their antlers in the late fall, well before Christmas. So Santa's reindeer, which all sport antlers, are therefore all female, which means Rudolf has been misgendered."

It is not the first time Tyson has found himself at the center of a Twitter storm, having sparked a bizarre online disagreement with food company Steak-umm.

The company's feud with Tyson started after the scientist tweeted in April this year: "The good thing about science is that it's true, whether or not you believe in it."

For some reason, those behind the Steak-umm's Twitter account took issue with Tyson's comment and tweeted: "Log off bro."

Steak-umm followed up with another tweet, which read: "The irony of Neil's tweet is that by framing science itself as 'true' he's influencing people to be more skeptical of it in a time of unprecedented misinformation. Science is an ever refining process to find truth, not a dogma. No matter his intent, this message isn't helpful."
