West African Ruler Abubakari II Brought Africans to America Before Columbus
Christopher Columbus wasn’t responsible for Africans ultimately coming to America.

The Earth’s atmosphere bears precious little resemblance to what it looked like at the start of the Industrial Revolution. As radio technology has advanced and spread, the signals that transmitters produce — specifically the Very Low Frequency (VLF) variety — have changed the way that the upper atmosphere and the Van Allen Radiation Belts interact, according to a study recently published in the journal Space Science Reviews. In effect, these radio waves may be enveloping the globe like an electromagnetic comforter, protecting it from satellite-frying space radiation.
