The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as ...

In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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.

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 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron. Reading time 2 minutes Physicists have placed a new limit on how big the elusive ...

For decades, physicists have suspected an interloper. A reclusive, hypothetical subatomic particle might be creeping into studies of neutrinos, nearly massless particles with no electric charge. A new ...

Behold, the world’s fastest microscope: it works at such an astounding speed that it’s the first-ever device capable of capturing a clear image of moving electrons. This is a potentially ...
