Yes, there are still people who believe the Earth is flat. One of those people might be B.o.B.

The Atlanta rapper took to Twitter and posted a photo with a pretty deep inquiry about how the distance between two cities were 16 miles apart, so he asked: “where is the curve?”

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

Relying on his savvy followers, they shared their own explanations to Bobby Ray's question. Some sound logical, others sound pretty troll-y. Even famed scientist Neil deGrasse Tyson is going in on Bobby Ray.

@Sam_Prudence @bobatl There is no edge, bro! That's because it's a ball, not round like a sphere but a ball with imperfect surface. — Bijou BAKSON (@BijouBAKSON) January 25, 2016

@bobatl 16 miles is 0.06% of the earth's circumference, you can't expect to see the curvature of earth in that distance — Sam Prudence (@Sam_Prudence) January 25, 2016

@bobatl you're a flat-earther? You know you can just observe shadows casted at the same time in different locations to prove earth is round. — Keize Montoya (@KeizeMontoya) January 25, 2016

@bobatl Keep spreading the truth B.o.B., I love it. People must know the truth, sick of lies and deceit taught to us for centuries. — ijcsly (@ilovemppb) January 25, 2016

@bobatl Eveybody is lying to us. The planet is not an actual planet. It's a giant potato. — Rafael Vazquez (@RafaelV702) January 25, 2016

B.o.B isn't quite convinced, though. He's trying really hard to prove to us that the Earth is flat, bringing up all sorts of research and photos to back up his point.

Time-lapse photos of stars form perfect circles... how is this possible ? pic.twitter.com/d9d1sJja8z — B.o.B (@bobatl) January 25, 2016

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

The ONE thing every country can agree on : restricted access to the poles ... Here's to the UN... we believe you pic.twitter.com/gBzDk23VWp — B.o.B (@bobatl) January 25, 2016

Are you still with him?

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

He's still going.

so u can see stars without light pollution , during sunset... but not from space ?😂😂 pic.twitter.com/MoMGwXelaC — B.o.B (@bobatl) January 25, 2016

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

In these tweets, he's referring to the Red Bull Stratos in 2012, a space diving project where skydiver Felix Baumgartner jumped from a space capsule above the Earth and free-falled until he parachuted and landed on his feet. He claims while on a flight he was at the same altitude as Baumgartner.

I was on a plane the SAME time the Red Bull jump happened. The pilot told us to lookout the window.. 5 miles to the left was the balloon — B.o.B (@bobatl) January 25, 2016

We were flying at the SAME altitude as the guy who did the red bull jump... NO curve... even tho their footage shows otherwise — B.o.B (@bobatl) January 25, 2016

So, is B.o.B right and science is wrong? And did he just announce himself as the newest member of the Flat Earth Society?

You can regurgitate force fed information all day... still doesn't change physics. — B.o.B (@bobatl) January 25, 2016
