The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on a subatomic subject.

Subatomic particles, gravity wells and the beginning of the universe – these are difficult and mysterious concepts that are ...

Some cosmic rays come from the sun, some from elsewhere in our Milky Way, and others, called extragalactic cosmic rays, trace ...

To test if antimatter can be safely transported, a team of scientists loaded antiprotons into a specially prepared truck.

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

The United States' military has announced it is seeking to create powerful subatomic particle beams that would enable personnel to "see" through walls tens of yards thick and even peer deep ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a test, but rather the physical stresses that affect everyday objects.

The new study suggests that primordial black holes helped create the matter-antimatter imbalance, resulting in the formation ...
