The more crucial a physical law is, the more important it is to keep testing it. One of the most important laws formulated in the last century or so is Albert Einstein's principle of invariance, which ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The greatest scientific legacy that Albert Einstein left us is this: ...

Lorentz invariance is fundamental to the special theory of relativity and the Standard Model of particle physics. The principle of Lorentz invariance states that the result of an experiment is ...

In 1887 one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of the Earth by comparing the speed of light in ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light moves through space at a constant speed has supported some of physics’ most ...

The concept of Lorentz symmetry underpins much of contemporary physics, serving as a central pillar in both the Standard Model and general relativity. The Standard Model Extension (SME) is a ...

BERLIN, Sept. 15 (UPI) --The speed of light is a constant. A new test -- the most precise test of a photon's speed -- confirms it. The results of the test support the concept of Lorentz symmetry, the ...

Where were we? Ah yes, spontaneous symmetry breaking. When some field takes on a nonzero value even in empty space, and that field is affected by some symmetry transformation, the resulting symmetry ...

A new generation of super accurate clocks are proving that Einstein’s idea that time is not absolute is correct. This is not great news for anyone looking for a unifying theory for everything from ...
