Scientists Found Never-Before-Seen Crystals in Dust From The Chelyabinsk Meteorite

Posted by 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

Posted by in categories: alien life, existential risks

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.

World’s first full-scale planetary defense test against potential asteroid impacts

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

A giant asteroid’s impact is considered the likely cause of the mass extinction of the dinosaurs almost 66 million years ago.

While there is no potential harm from an asteroid on the Earth at present, it is still important to keep our defense system ready in order to prevent catastrophic consequences such as impacts by deflecting trajectories of asteroids if one is ever discovered.

With this aim, NASA launched the Double Asteroid Redirection Test (DART) mission, the world’s first planetary defense test mission, last November. DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact. In summary, it is to collide with an asteroid and deflect it from its orbit in order to provide valuable information for the development of such a planetary defense system.

Can We Genetically Engineer Humans for Space?

Posted by in categories: alien life, existential risks, genetics, habitats

Traveling far distances in space is difficult, but advances in jet propulsion and genetics are making it possible. Trace is joined by Dr. Kiki Sanford to discuss how by altering the genes in our own bodies, we can make ourselves more fit to survive on other planets!
