The South American LIDAR scans they are doing now is wild! Entire civilizations. Cities with supposedly millions of people. Across much of the Amazon and S.America. Just gone. Overgrown and swallowed up by the jungle centuries ago.
Over 60,000 Mayan structures discovered!
I subscribe to it. Been wrapping up S.America: Incas, Mayans, Azteks. Their Mongol episodes are what pulled me in.
The "chambers" under the pyramids are fascinating to think about. Subterranean space under structures we'd be hard pressed to replicate with today's technology is a mind trip.
*assuming they are valid*
What is also wild is how ensconced archeologists are on their theories. Before Gobekli Tepe it was heresy to discuss civilizations that old and advanced. You'd get attacked, laughed out of the room, etc. Or the Clovis stuff. Ancient civilizations don't have to mean Star Trek - just that it's not inconceivable to think that as a species, there have been resets over the decades that fall outside the lines of a linear progression of humans as a species (or any species for that matter).
Always knew they had high levels of resistance, but this is wild:
Insects can survive radiation doses that are lethal to humans by a large factor. For example, cockroaches can tolerate 900-1000 grays, while doses of 3-6 grays can be fatal to humans.
Topics like the places above make me wonder how much credence there is with ancient civilizations? Think Younger Drays stuff. Randall Carlson, etc. We know the YD period happened. We know humanity had what many accept as a "reset" as much of the population was killed off.
Were there older civilizations with sufficient tech to construct such things as the pyramids, gobekli tepe, etc. with advancements more than simple stone tools and slave labor? 12K years ago, any metal such as iron/steel would turn to dust. Historical dates keep getting pushed back further and further with more findings of civilizations that are older and older. Cool to think about.
If a giant space rock slammed into the earth, all electronics are gone. Most of humanity dies off as they are not equipped to survive, and cities turn back into dust over a few thousand years.
I wouldn't carry one ever as he states above. I'd keep one in the safe, truck gun, etc.. I'm a massive SIG fanboy, first three pistols have been SIG's, but this is a problem.
Think Chevy/GMC 6.2L recall that can bankrupt a company type problem
If you already have a .22lr, Aguila sub-sonic ammo is the teets. Doesn't cycle in a semi, so make your shots count. Bolt gun or lever action would be optimal.
And get sued by the perps family in a civil trial, no thanks. Guy did good, albeit he was too close and holding the gun a little weird. Easy to armchair critique, but I bet his adrenaline was through the roof and he held it together.
