Disturbing Events that Almost Ended Humanity

The video "Disturbing Events that Almost Ended Humanity" by Visual Venture explores several historical and technological close calls that nearly led to humanity's extinction (0:39).

Here are the key events highlighted in the video:

The Day the World Almost Exploded (1:06): In 1961, a U.S. B-52 bomber carrying two nuclear bombs crashed in North Carolina due to a fuel leak (2:47). One bomb's parachute failed, and it slammed into the ground, but miraculously didn't detonate due to impact damage to its internal parts (3:57). The other bomb's parachute deployed, and it landed in a tree (3:37). Had either bomb exploded, it could have triggered a global nuclear war (5:04).

The Illness That Wiped Out a Continent (5:31): The Bubonic Plague, also known as the Black Death, arrived in Sicily in 1347 via trading ships (6:06). Carried by infected fleas on rats, the disease spread rapidly across Europe (6:38), leading to the death of an estimated 25 million people (9:20), over a third of Europe's population (9:22).

The Countdown to Doomsday (9:53): The Y2K bug was a computer glitch where older systems only stored the last two digits of a year (10:43). Programmers feared that when the year 2000 arrived, computers would interpret "00" as 1900, causing widespread system failures (11:36). This led to global panic, but extensive efforts by IT professionals to rewrite code (13:28) prevented a catastrophe (13:39).

The War That Almost Ended Civilization (13:48): World War II (1939-1945) is highlighted as the deadliest conflict in human history (13:51). The video discusses Adolf Hitler's rise to power (14:41) and the multiple failed assassination attempts against him (15:09). The use of atomic bombs on Japan in 1945 (16:31) brought the war to an end, preventing further widespread destruction and potential nuclear war (16:43).

The Year the Sun Disappeared (17:01): In 1815, the eruption of Mount Tambora in Indonesia (17:27) spewed massive amounts of ash and sulfur dioxide into the atmosphere (18:22). This blocked sunlight, leading to a "year without a summer" in 1816 (18:58). Global temperatures dropped, causing widespread crop failures (19:03), food shortages (19:15), and famine (19:19).

How One Man Saved the World (19:52): In September 1983, Soviet Lieutenant Colonel Stanislav Petrov (20:07) was monitoring an early missile warning system when it falsely indicated five U.S. missiles were heading toward the Soviet Union (21:03). Despite protocol, Petrov trusted his intuition that it was a false alarm (21:11) and reported it as such (22:08), preventing a potential nuclear retaliation (21:50) and a global nuclear war (21:57).
