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: ...

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 ...

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 ...

Physicists tested light speed using cosmic gamma-ray bursts. Study confirms Einstein's prediction that all light colors travel at same speed.

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

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 ...

RECENTLY, Lyttleton and Bondi 1 put forward the suggestion that the expansion of the universe is caused by the absolute values of the charges of the proton and electron not being equal, thereby giving ...

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 ...

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 ...
