Story highlights Rapper took to Twitter to argue Earth is flat

Insisted we should see planet's curvature on horizon

Posted photographs as evidence to support his claims

(CNN) Rapper Bobby Ray Simmons (more widely known as B.o.B) has taken to Twitter, insisting the world is flat.

The man behind chart-topping hits such as "Nothin' on You" and "Airplanes" has posted a flurry of tweets and pictures telling his 2.3 million followers: "I didn't wanna believe it either."

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

B.o.B laid out his case that if the world were in fact round, it would be obvious when looking at the horizon. He says cities in the distance would not be visible as they would be obscured by the Earth's curvature.

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

He also tweeted numerous photographs taken at high altitude, which he said further supports his point that "no matter how high in elevation you are... the horizon is always eye level."

Retweets were rewarded for the few who agreed with the musician. However, anyone responding negatively to the singer was simply shut down.
