Are cosmic collisions common? (3)

Are cosmic cataclysms common?
“… The myth and folklore of as many as fifty different cultures around the planet tell of similar global devastations, during which humanity went through a trial by fire and flood.”
“… a cosmic chain of events began 41,000 years ago and culminated in a major global catastrophe 28,000 years later. We refer to that culmination period of 13,000 years ago as simply the ‘Event.’”

“ SUMMARY OF THE MAIN EVENT
41,000 years ago a supernova exploded close to Earth
• The burst of radiation caused widespread extinctions in Australia and Southeast Asia
• Much of the human race perished in and near Southeast Asia
• Human genetic mutations led to larger brain size, fostering art, music, and a burst of creativity
• Being shielded from the explosion, the other continents were affected very little
• For about six months, the supernova was bright enough to be a second sun or moon
34,000 years ago the first shock wave of the supernova buffeted the Earth
• Radiation increased and small ions and particles bombarded Earth
• There also were increased comet and asteroid impacts
16,000 years ago the second shock wave of the supernova arrived
• As with first shock wave, radiation increased and small ions and particles bombarded Earth
• As well, there were increased comet and asteroid impacts
13,000 years ago multiple impacts of comet-like objects hit the Northern Hemisphere”

“WHAT THE EVIDENCE SHOWS
• Many radioactive isotopes support a three-phase event at 41,000 years ago, 34,000 years ago, and 13,000 years ago
• The three phases were (1) radiation (2) an initial shock wave and (3) a debris wave
• Gulf of California cores show a beryllium peak at 41,000 and 34,000 years ago
• The gulf cores also record a major pulse of meltwater around 13,000 years ago
• The same core indicates that the supernova caused the Earth’s magnetic field to flip briefly
• In ice cores, the supernova isotopes beryllium, chlorine, and aluminium all peak at 41,000 years ago
• The timing of all three events is consistent with what we know about supernova remnants

Comment: These are extracts from Firestone, West, and Warwick-Smith’ s The cycle of cosmic catastrophes : Flood, fire, and famine in the history of civilisation.
The authors then examined how supernova radiation has affected our genes and blood type.
