The wider lateral perspective enabled by such a lens would take us a little further back into relatively recent pre-history. Since events of the past do not normally repeat themselves (except man-made wars), researchers seem to combine ancient folklore with relevant modern scientific investigations, in order to reach speculative and tentative conclusions.
Such a conclusion by Firestone, West, and Warwick-Smith is set out in ‘The cycle of cosmic catastrophes: flood, fire and famine in the history of civilization.’ While unappetising, the information provided is challenging, yet absorbing. Their thesis is that, 41,000 years ago, a supernova exploded soundlessly, yet produced a colossal frighteningly visible flash, and terrible consequences for life on Earth.
The consequences were: a burst of invisible radiation, causing widespread extinctions in Australia and south-east Asia; the first shock wave then arrived unnoticed 34,000 years ago, with an increase in harmful radiation in the main; 16,000 years ago the third wave of “supernova stuff” in the form of “enormous dustballs” bombarded Earth; and 13,000 years ago, the debris wave arrived, with “multiple impacts of comet-like objects” in the northern hemisphere, viz. North America, Europe, and northern Asia. The consequences were horrendous.
Cosmic impacts, however infrequent, do have terrible consequences. Yet the authors conclude that “such massive impacts are nature’s way of cleaning house … “
So, is there purpose in the Cosmos, comparable (possibly) to the alleged operation of Gaia protecting Earth from the habits of humans?
