Physicists Detect Mysterious X Particles in ‘Primordial Soup’ For The First Time

by

A mysterious particle thought to have existed briefly just after the Big Bang has now been detected for the first time in the ‘primordial soup’. Specifically, in a medium called the quark-gluon plasma, generated in the Large Hadron Collider by colliding lead ions. There, amid the trillions of particles produced by these collisions, physicists managed … Read more

Weird structures near Earth’s core may be scars from a primordial interplanetary collision

by

A group of mysterious, ultradense structures just outside Earth’s core may be the remnants of an ancient interplanetary collision, new research suggests. These strange structures are known as ultralow-velocity zones (ULVZs), because seismic waves generated by earthquakes travel about 50% more slowly through these zones than through the surrounding mantle. That means the ULVZs are … Read more

Bits of asteroid Ryugu are among ‘most primordial’ materials ever examined

by

Tiny particles of rock gathered from the asteroid Ryugu are some of the most primordial bits of material ever examined on Earth and could give us a glimpse into the origins of the solar system. Asteroid 162173 Ryugu measures about 2,953 feet (900 meters) in diameter and orbits the sun between Earth and Mars, occasionally … Read more

Exciting New Paper Tests a Dark Matter And Black Hole Prediction Made by Hawking

by

The Universe is too heavy. According to our measurements of the normal matter in the Universe, there’s not nearly enough of it to account for the strength of the gravitational effects we can see.   Whatever is making up the rest of the mass is nothing we can detect directly, and the quest to figure … Read more
