Göbekli Tepe

Carbon dating shows that the complex is 12 ka old. Stonehenge was built around 2000–2500 BC. Gobekli Tepe hails from a part of human history that is unimaginably distant, right back in our hunter-gatherer past.

There is no doubt gobekli tepe is an enormously important archaeological discovery: at 12 ka, it is far far older than any other advanced manmade structure. together with evidence that the first grains are from the same area, this may well be the birth of civilization.

Göbekli Tepe suggests a reversal of that scenario: The construction of a massive temple by a group of foragers is evidence that organized religion could have come before the rise of agriculture and other aspects of civilization. It suggests that the human impulse to gather for sacred rituals arose as humans shifted from seeing themselves as part of the natural world to seeking mastery over it. When foragers began settling down in villages, they unavoidably created a divide between the human realm—a fixed huddle of homes with 100s of inhabitants—and the dangerous land beyond the campfire, populated by lethal beasts.

2022-05-20: The area might be even older and is far more widespread:

Archaeologists in southeastern Turkey are digging up a wild, grand, artistically coherent, implausibly strange, hitherto-unknown-to-us religious civilization, which has been buried in Mesopotamia for 10 ka. And it was all buried deliberately. Karahan Tepe is stupefyingly big. ‘So far We have dug up maybe 1% of the site. That’s probably another megalith right there, waiting to be excavated. I reckon there are probably 1000s more of them, all around us. We are only at the beginning. And there could be 10s more Tas Tepeler we have not yet found, spread over 100s of kilometres.’

Underground city

Manhattan will be gone, Los Angeles gone, Cape Canaveral flooded and covered with seaweed, London dissolving into post-Britannic muck, the Great Wall of China merely an undetectable line of minerals blowing across an abandoned landscape – but there, beneath the porous surface of Turkey, carved directly into tuff, there will still be underground cities.

truly a wonder of the world. glimpses at things like cappadocia really make you wonder what was going on in ancient times. it often feels like we got the sanitized version, the kids stuff.

Sagalassos

The last inhabitants finally abandoned the crumbling civic center around the middle of the 7th century AD, when the socio-economic network of the town was shattered by another major earthquake, new epidemics and the first Arab raids. The transition from a farming society to pastoralism, mainly that of goats, eventually resulted in a massive erosion which covered the ruins of the abandoned city. As a result, Sagalassos, which was never looted in later periods, remained one of the best preserved ancient urban sites in the Mediterranean.

Nuclear Weapons

Broken pipes and rusty fences. If that ain’t scary, few things are.

The main entrances to Los Alamos are only marginally better defended than TA-33’s land. The military-like guards keeping watch at these points certainly look fierce in camouflage paints and black bulletproof vests. But there’s little to back up the image. Their belts have gun holsters, but no guns to fill them. Around facilities like the biology lab, where anthrax and other biotoxins have been handled, no sentries stand guard at all. Nor is there any kind of fence to keep the curious and the malicious away — not even a piece of string.

2006-10-09: Might it all be posturing?

The United States Geological Survey is now reporting the magnitude of the claimed North Korean nuclear test as 4.2. This seems to be curiously low. Now, estimating explosive yield from the body magnitude of a seismic event is a tricky business, and requires knowledge of details such as the depth of the detonation and the geological properties of the surroundings, but a magnitude around 4.2 is what you’d expect for a detonation of 1 kiloton. The “natural size” of a crude fission bomb is in excess of 10 kilotons, from which you’d expect a magnitude closer to 5. It is very unlikely that a low kiloton yield device would be used in an initial test.

2008-06-28: Man-made nuclear explosions in the 1940s and 1950s released isotopes into the environment that do not occur naturally, allowing the dating of works of art.

2010-11-25: Nuke Detector. Turn a supertanker into an antineutrino detector by kitting it out with the necessary photon detectors and filling it with 10^34 protons. Then station it off the coast of suspicious countries and submerge it.
2013-11-26: India nuclear assassinations and the Indian government is mum about it. Nuclear scientists have very high mortality in Iran too, but the government there is making a huge ruckus about it.

Indian nuclear scientists haven’t had an easy time of it over the past 10 years. Not only has the scientific community been plagued by “suicides,” unexplained deaths, and sabotage, but those incidents have gone mostly underreported in the country—diluting public interest and leaving the cases quickly cast off by police.

2014-02-05: Nuclear backpacks

during the Cold War, the United States did deploy man-portable nuclear destruction. If Warsaw Pact forces ever bolted toward Western Europe, they could resort to nukes to delay the advance long enough for reinforcements to arrive. These “small” weapons, many of them more powerful than the Hiroshima bomb, would have obliterated any battlefield and irradiated much of the surrounding area.

2014-11-15: X-Ray Man

In 1957, a young man named Darrell Robertson enlisted in the US Army and participated in a secret training program in the middle of the Nevada desert. He and his fellow recruits were sworn to secrecy and, for decades, told no one of their experiences. In 1996, the US government declassified the project and Robertson was finally able to tell his story. In X-Ray Man, Robertson recalls training exercises in which the Department of Defense used him and other soldiers in nuclear tests more than 10 years after the horrors of Hiroshima and Nagasaki were already well known. Kerri Yost’s powerful short documentary is an account of how Cold War-era fears allowed for shocking treatment not just of supposed enemies, but also of those enlisted to fight against them. Though cancer has attacked his body, Robertson, supported by his wife, remains stoic and dignified, offering the quiet but forceful observation that ‘any person in the military becomes part of military science’.

2015-09-09: Nuclear wars for SETI. Nuclear explosions might be the first thing we see of other life at interstellar distances. Gamma rays are much easier to detect than radio waves, but would only last a few days at most. You’d have to be extremely lucky to catch that, but then we can spot GRB like that all the time.
2016-07-17: The H-Bombs in Turkey

Among the many questions still unanswered following Friday’s coup attempt in Turkey is one that has national-security implications for the United States and for the rest of the world: How secure are the American hydrogen bombs stored at a Turkish airbase?

2021-02-20: $100b nuclear deterrence

To avoid being destroyed and rendered useless—their silos provide no real protection against a direct Russian nuclear strike—they would be “launched on warning,” that is, as soon as the Pentagon got wind of an incoming nuclear attack. Because an error could have disastrous consequences, James Mattis testified to the Senate Armed Services Committee in 2015 that getting rid of America’s land-based nuclear missiles “would reduce the false alarm danger.” Whereas a bomber can be turned around even on approach to its target, a nuclear missile launched by mistake can’t be recalled.
