Recently, the weirdest beef in recorded history happened: rapper B.o.B. and astrophysicist Neil deGrasse Tyson went toe to toe after B.o.B. made claims on Twitter that the Earth is flat.
Tyson, one of the most recognizable scientists in the world, actually took the time to explain to B.o.B. why he was mistaken. Unfortunately, the lesson wasn't well-received and the rapper actually released a diss track about Tyson. The song, titled "Flatline," has since been deleted from Soundcloud but still exists on YouTube.
Tyson's nephew struck back with his own track called "Flat To Fact," a parody of "Back To Back," the Grammy-nominated diss track by Drake directed at Meek Mill. Tyson also came at B.o.B. hard on The Nightly Show, dropping knowledge and his mic.
While it seems unreal that there are still actual people in 2016 who not only believe the Earth is flat, but they're somehow allowed to talk and vote and have a driver's license, it was once accepted as truth.
Because the Earth feels more or less flat while you're walking around on it, it seemed pretty obvious. However, once scientists really started paying attention, there were irrefutable signs that our world was, indeed, round.
The latest DNews video breaks down the history of how scientists came to understand this truth and how they were able to make some incredible calculations without the use of computers or calculators.
