"But in order to produce effects like the ones seen in the tree rings, such a supernova would have had to have been within 100 light years or so. Such an event would have been blindingly bright in the sky, much brighter than a full moon. It would have been bright like that for months and could not have failed to be noted by every civilization on Earth. Being so close, there would be remnants of the explosion visible today, still expanding. Something so close could not have been missed."Velikovsky, amongst others, from accounts of austensibly drunk shaman and wild eyed witch doctors long before his and our time noted MANY such phenomena in the heavens. Along with a good deal of contemporaneous nastiness on earth. Were they all a bunch of Neanderthal twits??? The arrogance of today's scientific community™ is their belief that earlier humans couldn't tell the difference between the sun and a large campfire.
I may be missing something here but from what I've been able to gather from the little reading I've done re gamma ray bursts is that the part we SEE that could affect us can last from fractions of a second to several minutes; then they're gone. Like they were never even there??? The author(s) may be assuming that every supernova explosion leaves a lasting impression. Maybe they do; maybe they don't...
That being said, our sun very likely produces some spectacular, even devastating fireworks from time to time.
Yes, and we’re about due for another “Carrington event”...and our idiots in the Senate voted down the bill that would have mandated hardening of the electrical grid.
By the way, have you watched David Talbot’s “Symbols of an Alien Sky” videos? Check him out on YouTube if you haven’t already.
