Asteroid impacts create diamond materials with exceptionally complex structures

Posted by in categories: asteroid/comet impacts, energy, engineering, existential risks

Shockwaves caused by asteroids colliding with Earth create materials with a range of complex carbon structures, which could be used for advancing future engineering applications, according to an international study led by UCL and Hungarian scientists.

Published today in Proceedings of the National Academy of Sciences, the team of researchers has found that formed during a high-energy shock wave from an around 50,000 years ago have unique and exceptional properties, caused by the short-term high temperatures and extreme pressure.

The researchers say that these structures can be targeted for advanced mechanical and electronic applications, giving us the ability to design materials that are not only ultra-hard but also malleable with tunable electronic properties.

Universities have an urgent mission: Make lying wrong again

Posted by in categories: education, existential risks

The potential to disseminate disinformation on a large scale and undermine scientifically established facts represents an existential risk to humanity. While vigorously defending the right to freedom of expression everywhere, higher education institutions must also develop the capacity to reach a shared, empirically backed consensus based on facts, science and established knowledge.

Why Is NYC Preparing Its Citizens for a Nuclear Attack?

Posted by in category: existential risks

Has New York City gone too far with this public service announcement? The city’s office of Emergency Management released this ad, telling residents what to do in the event of a nuclear attack. The host tells people to take cover indoors immediately. If you’re outside when the strike occurs, residents are advised to shower, bag their clothes. Then, pay attention to local media for information and next steps. Inside Edition Digital’s Mara Montalbano has more.

The Last Human — A Glimpse Into The Far Future

Posted by in categories: asteroid/comet impacts, climatology, existential risks, sustainability

The Last Human – A Glimpse Into The Far Future.

German animation and design studio, Kurzgesagt, explores the far future of humanity and how our population may change over the aeons.

Given the numerous global threats we face during this century and beyond – from climate change to nuclear war, asteroid impacts and killer viruses – many of us are concerned that humans could go extinct. But there are reasons to be optimistic, according to this latest video from Kurzgesagt. Rather than approaching the end of human history, we may actually be living at the dawn of our species; the mere prelude for a vast and exciting future that lies ahead.

Scientists Update Course Of Asteroid Headed Towards Earth

Posted by 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.

NYC Prepares for the ‘Big One’ With Nuclear Attack PSA Video

Posted by in category: existential risks

In the event of a nuclear disaster, would you know what to do? If you’re a New York City resident, there’s a YouTube video for that.

The city’s Department of Emergency Management released a public service announcement video outlining the three steps that residents should take in case of a nuclear attack.
