Cannikin In 1971, the United States conducted the Cannikin test, in Alaska. The largest underground nuclear weapons test in American history. The 5-megaton bomb (about 400 times more powerful than the one dropped on Hiroshima) was detonated at a depth of approximately 1,790 meters below the island's surface. The detonation produced a seismic shock of magnitude 7.0 on the Richter scale, causing the ground to lift by about 6 meters, followed by subsidence that created a crater lake over 1 mile wide and about 12 meters deep. Reports indicate that the environmental effects were significantly greater than those predicted by the Atomic Energy Commission.

On November 6, 1971, this nuclear test shook the entire Earth.. On November 6, 1971, the United States conducted Cannikin, the largest underground nuclear test in history, on Amchitka Island, Alaska. Detonated nearly a mile beneath the surface, the blast had a yield of nearly 5 megatons—over 300 times the power of the Hiroshima bomb. The explosion was so immense that it lifted the ground above several meters and sent seismic waves equivalent to a magnitude 7.0 earthquake rippling through the region. Shockwaves were felt across Alaska, and the Earth itself literally “rang” from the force. Despite widespread fears of tsunamis and geological devastation, the government declared the test a technical success. Cannikin stands as a stark symbol of Cold War nuclear ambition—a moment when humanity unleashed weapons powerful enough to move the planet itself.

🚨BREAKING: US TESTS DOOMSDAY MISSILE CAPABLE OF NUCLEAR WARHEADS 20X MORE POWERFUL THAN HIROSHIMA BOMB The United States has test-launched a Minuteman III intercontinental ballistic missile also known as Doomsday missile, from California, according to New York Post. The missile lifted off from Vandenberg Space Force Base near Santa Barbara. Launch time was reported around 11 p.m. local time. The system is reportedly capable of carrying nuclear warheads that are 20 times stronger than Hiroshima’s bomb. The unarmed missile traveled across the Pacific Ocean. It struck its designated target near the Marshall Islands. Officials say the test verified readiness, accuracy and system performance.

Wow. China just compieted an in-flight abort test of their crewed Moon spacecraft. This was the last major milestone before the agency can conduct an uncrewed orbital flight to their space station at the end of 2026. Mengzhou can carry a crew of 7 to orbit or 3 to the Moon.

On November 6, 1971, the United States carried out Cannikin, the largest underground nuclear explosion ever recorded, on Amchitka Island in Alaska. The device, buried nearly a mile underground, unleashed a force of almost 5 megatons making it more than 300 times stronger than the bomb dropped on Hiroshima. The detonation was so powerful it raised the earth above the test site by several meters and sent shockwaves through the ground, producing tremors equal to a magnitude 7.0 earthquake. The seismic impact was felt throughout Alaska, and the force was strong enough to make the planet "ring." While concerns about tsunamis and severe geological damage circulated, officials ultimately deemed the test a technical success. Cannikin remains a vivid reminder of the lengths pursued during the Cold War era, when nuclear tests reached a scale that could literally shake the world.

On this day in 1919, Germany signed the Treaty of Versailles, agreeing to pay 132 billion gold marks in war reparations, roughly $33 billion at the time. The burden equaled more than twice Germany's annual GDP. John Maynard Keynes resigned from the British delegation in protest and published "The Economic Consequences of the Peace," warning that the terms would destabilize all of Europe. To meet the payments, the Weimar government printed money at a catastrophic pace: by November 1923, a single U.S. dollar bought 4.2 trillion marks, and the resulting hyperinflation wiped out the savings of an entire generation of Germans. Germany didn't finish paying off the debt until October 2010, when it made a final $94 million installment, 91 years after the treaty was signed.

Skeptical about my theory?Take a look at the Pokémon LegendsZA logo,the letters are…pink👀 And you know what could be a perfect already existing Rakurium counterpart of the in-game(Z-A)lore? …The crystal that the sundial is made of. That crystal could be the same rock that Rayquaza ate that made it develop the mikado organ. The sundial and the rocks Rayquaza ate, both originated from space, and both cause mega evolution in their own ways. Also this is more of a loose connection but we technically don’t know what the material of the crystal-looking-pieces of the ultimate weapon are made of either🤔 They could all be the same gemstone/meteorite, rich in infinity energy and that came from outer space.

Today in 1946, the U.S. carries out the famous "Baker" nuclear test at Bikini Atoll in the northern Marshall Islands. The 23-kiloton blast engulfs a fleet of 95 surplus warships, including the carrier Saratoga, Yamamoto's flagship the Nagato and the German cruiser Prinz Eugen. (ODD SIDEBAR: Hundreds of goats and pigs were placed aboard the vessels to measure the effects of a nuclear blast upon ships' crews. The vast majority of animals perished in the explosion; a handful of surviving animals died later of radiation sickness. Incredibly, one baby pig, known only as #311, somehow survived after suffering minor radiation exposure. She was taken back to the U.S. for further study where she recovered. The animal became a popular Washington D.C. zoo attraction and lived another four years.)

July 16, 1945. At 5:29 in the morning, in a stretch of New Mexico desert so brutal the Spanish had named it the Journey of the Dead Man, the United States detonated the first nuclear weapon in history. They called the test Trinity and they called the bomb itself the Gadget. Nobody was totally sure what would happen. Scientists had a betting pool going on the yield, and a couple of them had quietly worried whether the thing might ignite the atmosphere itself. They went ahead anyway. The flash lit up the mountains brighter than the sun. People felt it 100 miles away, windows rattled in distant towns, and the heat fused the desert sand into a weird green glass that scientists later named trinitite. The Army put out a cover story that an ammunition dump had exploded. Robert Oppenheimer later said that watching it, he thought of a line from Hindu scripture. Now I am become Death, the destroyer of worlds. Another physicist there put it more bluntly and said now we are all sons of bitches. Three weeks later Hiroshima was gone. The world changed at dawn in a desert on this day.
