There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life’s final extinction will occur.

NASA Reveals How It Would Warn World of Impending Asteroid Disaster
When the Chicxulub impactor, a six-mile-wide asteroid, struck Earth 66 million years ago, the dinosaurs had no warning.
If an asteroid that size hit Earth today, a shock wave two million times more powerful than a hydrogen bomb would flatten forests and trigger tsunamis. A seismic pulse equal to a magnitude 10 earthquake would crumble cities.
And long after the impact, a cloud of hot dust, ash, and steam would blot out the sun, plunging the Earth into freezing cold.
Oppenheimer’s Grandson Signs Letter Saying AI Threatens “Life on Earth”
J. Robert Oppenheimer’s grandson is among the star-studded signatories of a new open letter about the dangers artificial intelligence poses to the planet.
The letter, which was issued by the Nelson Mandela-founded group The Elders in conjunction with the Future of Life Institute, calls on global decisionmakers to “show long-view leadership on existential threats,” including “ungoverned AI” and nuclear weapons.
Charles Oppenheimer, who founded the Oppenheimer Project to continue his grandfather’s mission of tempering scientific progress with “international cooperation and unity,” was joined by hundreds of others, including British billionaire Richard Branson, AI pioneer Geoffrey Hinton, writer and Carl Sagan widow Ann Druyan, and musician Peter Gabriel. In it, they warn that the world “is in grave danger” as we face down the perils of AI.
Fermi Paradox: The Impossible Earth hypothesis
The aliens haven’t contacted us because they have uploaded themselves into digital information where they live forever anf create simulated universes that they live in or they upload themselves into femto tech level computational substrates and they could surround us.

Asteroid Impact Near Berlin Reveals Rare Aubrite Treasures
Jenniskens’ collaborators at the Museum für Naturkunde officially announced that the first examinations of one of these pieces with an electron beam microprobe prove the typical mineralogy and chemical composition of an achondrite of the aubrite type.
The official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called “aubrites.”
“They were devilishly difficult to find because, from a distance, they look like other rocks on Earth,” said SETI Institute meteor astronomer Dr. Peter Jenniskens. “Close up, not so much.”
Would We Want to Live Forever?
More deathism from Mr Tyson. Really I’m a big fan but I dislike this sort of thinking. I commented on the vid.
What if we could live forever? Neil deGrasse Tyson takes us through life and death: if we could live forever what would life really mean? We explore why fresh flowers have meaning and why dogs make every day count. Learn about the Cretaceous-Tertiary Event, The Permian-Triassic Extinction, The Holocene Epoc, and how Earth is one killing machine.

Inside secret Bond-style Alpine vault ‘backing up Earth’ in case of WW3
Some recent progress on our backup of civilization project …
A SECRET project to back-up planet Earth in the event of apocalypse is underway in a James Bond-style villain bunker in the Swiss Alps.
As a hotbed of conflict explodes around the globe with fears of all-out World War Three mounting, a US firm has installed a British-designed “superman” memory disk containing a compendium of human history.
Located deep inside a mountain vault near Flums, Switzerland, the futuristic quartz disk — designed by boffins at Southampton University’s Optoelectronics Lab — holds 60 million microscopic pages of human knowledge.
