Physicists find it staggering, however, there are many somebody globally whom undoubtedly believe our planet was flat. Rachel Brazil examines as to why such views is actually increasingly bringing keep and you may how the physics neighborhood should finest act
Inside 2017 the united states rap artist B.o.B (real identity Bobby Beam Simmons Jr) come a crowd-financial support campaign to help you launch a great satellite. The new rap artist, a vocal proponent regarding “flat-Environment principle”, desired to seek research our entire world is actually a disc, perhaps not a globe.

Brand new rapper’s trip appears like bull crap or visibility stunt. Actually, there is currently no research one B.o.B raised far money otherwise got anywhere near their objective. not, over the last lifetime there has been a surprising rise on amount of people whom, such as for example B.o.B, believe in apartment-Environment ideas.
