Researchers of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, used a calcium ion to simulate a relativistic quantum particle, demonstrating a phenomenon that ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

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 ...

UPTON, NY--The 20th year of particle collisions is underway at the Relativistic Heavy Ion Collider](RHIC), a U.S. Department of Energy Office of Science user facility for nuclear physics research at ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

DURHAM, N.C. -- One of the tiniest building blocks of the universe has a weigh-in problem, and Ashutosh Kotwal is determined to get to the bottom of it. For nearly 30 years, the Duke physicist has led ...
