Neil deGrasse Tyson Slams B.o.B For Insisting The World Is Actually Flat

Neil deGrasse Tyson used a mysterious power source called "facts" to shut down a rapper who believes the Earth is flat.

Over the weekend, Atlanta-based rapper B.o.B tweeted several observations to purport the claim the Earth cannot be round, largely because of the way the outside world is perceived by the human eye.

His tweets continued this morning.

One of the first tweets, which has since been deleted, asked why there doesn't seem to be a curve when you look out into the ocean.

B.o.B reportedly wrote,

How do you explain the horizon always being at eye level?

He then questioned why Philadelphia is visible from New Jersey.

He had the same questions about New York City and upstate New York.

He also wanted to know why you can always see the North Star.

Why don't planes end up in space when they go straight?

Rather than completely dismiss him (as many would be tempted to do), astrophysicist Neil deGrasse Tyson countered the rapper's claims with some simple facts about the locations in question.

Tyson corrected B.o.B's remark about New York City...

...before asking him to check his eyesight next time he's way down South.

Tyson then admitted B.o.B's opinions are legal...

...and, apparently, they can still get along just fine.

B.o.B's response to Tyson's last tweet, however, shows he still refuses to conform.

He asked,

Why does only NASA have photos of the curve?
