The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at ...
According to our current understanding of the universe, quarks are fundamental, point-like particles: basic building blocks ...
There has been considerable debate among physicists over the last 15 years about conflicting measurements of the charge ...
If there weren’t any planets, stars, comets, asteroids, or other cosmic debris flying around, there would be merely the ...
Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help ...
One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This "self-coupling" could help explain the evolution of the early universe and the mechanism ...
By tracing the origins of an unusual, short-lived particle, researchers have gathered some of the strongest evidence yet that ...
Scientists at the Relativistic Heavy Ion Collider have observed particles emerging directly from empty ...
Scientists have observed particles forming from the vacuum, revealing how matter may emerge from seemingly empty space.
The ALICE experiment at the world's most powerful particle accelerator, the Large Hadron Collider, has given scientists their ...
A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ (Xi-cc plus), this entity resembles the proton but has a greater mass, as ...
