Physicists find they incredible, but there are numerous somebody globally just who certainly believe our planet was apartment. Rachel Brazil explores why for example viewpoints are much more delivering keep and you will how physics neighborhood is better react
Inside the 2017 the us rap artist B.o.B (real label Bobby Beam Simmons Jr) started a crowd-money campaign to discharge a good satellite.

The rapper’s trip may seem like a joke otherwise coverage stunt. In fact, you will find already no facts that B.o.B elevated much money or got anywhere near their mission.
