Scientists Update Course Of Asteroid Headed Towards Earth
Posted by Quinn Sena in categories: asteroid/comet impacts, existential risks, military
While it may seem a bit silly to think about an asteroid hitting the planet in 2052, the 2021 QM1 hitting Earth would be devastating. The asteroid is said to be 50 meters or 150 feet in diameter. Should it impact, it would have a force of six tons of TNT. To put that in perspective, it would be 400 times more powerful than the atomic bombs that had been dropped on Hiroshima. That would certainly be enough to destroy a large city and much more. There had been a 12-megaton asteroid that hit Earth over a remote part of the Siberia region. The impact flattened over 830 miles of forest, and three people were said to have died because of the impact. However, if that impact happened anywhere that was populated, that entire city, town, or state would essentially have been wiped off the map.
The 2021 QM1 had initially been discovered in August of 2021 at the Mount Lemmon observatory. It was discovered along with a dozen other asteroids. However, during Asteroid Day 2022 which took place in June of 2022, the ESA (European Space Agency) deemed that the 2021 QM1 asteroid would be completely safe and not strike the earth. Another asteroid by the name 2022, AE1, was also said to be on a collision course with the planet before it was recently deemed safe as well. The 70-meter asteroid is said to strike the moon before it would hit our planet. That might not seem like good news, considering the moon being destroyed might cause significant other damage to the planet, but it’s still good news.
Thankfully, there are scientists and astronomers that revolve their lives around studying the trajectory of rogue asteroids. They are meant to alert the planet should we be in any imminent danger. However, would the public go a bit crazy if they knew a giant asteroid was catapulting straight to Earth? Hopefully, they would not. Mass hysteria is always something to think about when there is a credible threat that cannot be vanquished by our modern technology.

Scientists Found Never-Before-Seen Crystals in Dust From The Chelyabinsk Meteorite
Posted by Quinn Sena in categories: asteroid/comet impacts, existential risks
Researchers have discovered never-before-seen types of crystal hidden in tiny grains of perfectly preserved meteorite dust. The dust was left behind by a massive space rock that exploded over Chelyabinsk, Russia, nine years ago.
On 15 Feb 2013, an asteroid measuring 59 feet (18 meters) across and weighing 12,125 tons (11,000 metric tons) entered Earth’s atmosphere at around 41,600 mph (66,950 km/h).

The Fermi Paradox: Multiverse

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
The Fermi Paradox contemplates the weirdness of our galaxy seemingly being devoid of intelligent alien life, but Many Worlds Theory, Multiverses, Parallel Universe, and Alternate Realities may radically alter our thinking on Aliens & SETI.

Anything not forbidden is mandatory quote by TH white once and future king.
An exploration of the notion that extinction by unforeseen means is a solution to the Fermi Paradox and that all civilizations in the universe blunder into extinction without seeing it coming.
