(via Sabine Hossenfelder) Physicists recently published a new paper noting that tachyons, particles that move faster than the speed of light, can exist after all. Is this just more hype over nothing, ...

About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with ...

Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

A team of Concordia researchers has developed the first micromotors capable of moving through the air using only light as their power source. These tiny, pollen-shaped particles measure about 12 ...

Reproducing the primordial universe When two atomic nuclei collide at near-light speeds, they generate temperatures more than 1,000 times higher than those at the center of the sun. These collisions ...
