Last year, rapper B.o.B. made headlines for his statements about earth being flat and insisting that he was right and the 'earth being spherical' thing was all a big conspiracy.

It led to an argument with astrophysicist Neil deGrasse Tyson, but still the 28-year-old Georgia rapper refused to back down on his views.

Now, he's at it again - this time, claiming that the total solar eclipse that was visible across the US yesterday doesn't necessarily disprove his 'flat earth' theory because the moon apparently generates its own light.

He had an exchange with several people on Twitter who tried to reason with him - with one saying "So you're telling me there are light bulbs in the moon? How the hell does it generate light? It's a rock. Is it flat to you too?"
