While NASA recently proved it can successfully alter the In my book Magicians of the Gods I examine the paradigm-shifting evidence for a cosmic impact 12,800 years ago, followed by further cataclysmic impacts 11,600 years ago. The argument, strongly supported by a number of leading astronomers and astrophysicists, is that both these groups of impacts originated from the same […] Every year, on average, an "automobile-sized asteroid" plummets through our sky and explodes, explains NASA. Impacts by objects around 460 feet in diameter occur every 10,000 to 20,000 years, and When the asteroid plowed into the Earth, tiny particles of rock and other debris were shot high into the air. Geologists have found these bits, called spherules, in a 1/10-inch-thick layer all When a meteor hits Earth, terrestrial rocks at the impact site can liquefy from the intense heat and then cool into glassy tektites, according to the Jackson School Museum of Earth History at The 0lfSj.
