Cool Science thread

Gamma ray burst we're all dead in short order, so NBD, really. But a big CME destroying almost every electrical circuit on Earth and every satellite in orbit? Now shit's getting real.

In my mind, the archaeological discovery of ancient populated areas being destroyed by something like a cosmic airburst is random. They likely had research questions at the start of their excavations.

[abraham]

I took that to mean two cities destroyed, not megaton-scale airbursts. Presumably there have been a lot more of the latter. We certainly know about every single one that has happened since the dawn of the nuclear age.

Airburst wouldn't create a tsunami, I assume. It is interesting to wonder how many oceanic impacts may have happened that created locally- or regionally-significant tsunamis but didn't create global effects.

There was another settlement in the middle east that likely was destroyed the same way 13,000 years ago. https://www.nature.com/articles/s41598-020-60867-w

And then there's Tunguska 100 years ago.

Yeah, that why I said "two" cities. We can be pretty confident that a Tunguska-scale event has not happened since Tunguska, even if it happened in the middle of the Pacific. We've been listening for atmospheric nuclear explosions since the dawn of the nuclear age, and megaton-scale blasts are easy to hear.

That Sodoma y Gomorrah research might be have to be enjoyed with a pillar of salt...
Doubts & critique of the methodology etc.

I can’t believe there’s been no references to the 70's film Sodom and Gomorrah - the last 7 days. I was young and only remember the gherkin scene....

If that's what it takes to finally vanquish the universe of humanity's scourge that is TikTok, then I'm game. Bring it!!!

Wow, great link.

That video about Earth’s 2nd moon was fascinating. Complete nerd, but the guy had great graphics and made it very easy to understand. Blown away by this link.

This is fascinating. From the event, to the analyses, to the conclusions, to the potential oral tradition that was recorded in the Bible to the reminder of the intensity and length of dense human occupation in some areas of the world.

I’m also very interested in the period, but this article is getting ripped apart by the archaeological and earth science communities.

Yeah. Numberphile, Computerphile and Sixty Symbols have really interesting stuff to watch.
Add to that the man with the funny hair, Periodic Videos, and one has the weekend sorted...

Wow, prehistoric skis still with the bindings. Were they mounted on the line?

How do you ski those switch to the road?

I'm glad this woman is no longer suicidal, happy even, but this is basically the premise of The Terminal Man. Hopefully MDMA/psilocybin-assisted therapy gets approved soon because it seems to get similar results without having to implant a device inside the patient's skull.

There is no evidence that prehistoric norsemen ever skied switch. Skiing backwards is yet one more way in which modern humankind has lost its connection to the natural world. Are you aware of any species that move backwards as a main form of locomotion? Didn't think so. There are crabs that reportedly move sideways, but that's it.

pood. yep.

Yes. I find that interesting.

Yes. I find that interesting.

I came across it because I follow Mark Boslough. His threads had most of the hard science. He’s admittedly not an archeologist. This explains a lot of the background:

Crayfish swim backwards?

Cool info about one of Saturn’s moons. Discovered in 1671 by Cassini himself, and we still don’t understand what the fuck is going on.

I don't know where else to post this but NE WA, N ID and Canada mags should go outside and look to the north. The aurora is out and pretty impressive.
