B.o.b. would like to check and then double check again with you: Is the Earth really flat?

The cities in the background are approx. 16miles apart... where is the curve ? please explain this pic.twitter.com/YCJVBdOWX7 — B.o.B (@bobatl) January 25, 2016

Early Sunday night, the rapper and Twitter power user — with more than 2.29M followers — strongly hinted that the earth may be flat as a frikkin' pancake.

B.o.b., whose real name is Bobby Simmons Jr., harnessed the power of some of the Internet's strongest resources — Google Earth screen grabs and some pulls from an unnamed textbook — to state his space case.

have u been to the edge ? or is that what your science book told you https://t.co/61qaI5xx5f — B.o.B (@bobatl) January 25, 2016

No matter how high in elevation you are... the horizon is always eye level ... sorry cadets... I didn't wanna believe it either. — B.o.B (@bobatl) January 25, 2016

Twitter tried its best to offer guidance and counterarguments, but B.o.b. seemed to have an answer for everything. Users on the social media site tried using both inflammatory comments and good ol' physics to reason with the rapper, but nothing seemed to stick.

y'all be like... "you're not high enough to see the curve...keep going" pic.twitter.com/dzgYpIIao3 — B.o.B (@bobatl) January 25, 2016

It's probably safe to say that B.o.b. is one opinionated guy. Plus, if you lived it, you do tend to believe it.

don't try to back me into the "conspiracy theorist" corner... don't be fooled. I speak from personal experience. — B.o.B (@bobatl) January 22, 2016

Recently, the Strange Clouds singer made enough waves on Twitter to attract the attention of another heavy hitter: Neil deGrasse Tyson. The learned astrophysicist did not hold back from throwing down some factual knowledge. And B.o.b. did not hesitate to fire back either:

@bobatl Polaris is gone by 1.5 deg S. Latitude. You’ve never been south of Earth’s Equator, or if so, you've never looked up. — Neil deGrasse Tyson (@neiltyson) January 25, 2016

@bobatl Flat Earth is a problem only when people in charge think that way. No law stops you from regressively basking in it. — Neil deGrasse Tyson (@neiltyson) January 25, 2016

@neiltyson why can't the curvature of the earth be measured anywhere in nature? why does only NASA have photos of the curve ? r u a mason? — B.o.B (@bobatl) January 25, 2016

Oh, and one last thing, for science's sake — what's your take on the whole "moonwalk" thing, Bobby?
