Carl Sagan's accurate prediction of the future

[SCantiGOP]

3. and Arthur C Clarke

Famous story about him being visited by government agents about a story he wrote in the 40s when the Manhattan Project was the most secret thing going on. His story involved using nuclear technology as a weapon, except in his case he had Soviet airplanes dusting our Air Force planes with highly radioactive dust so they were rendered unusable.
They realized that he was merely making predictions based on the current understanding of nuclear physics of that day.

We should listen to very smart people. It is not a coincidence that almost all of them are appalled by the Trump/evangelical/Tea Party nonsense going on in this country.
