A jarring divide cleaves modern physics. On one side lies quantum theory, which portrays subatomic particles as probabilistic waves. On the other lies general relativity, Einstein’s theory that space ...

Fundamental physics faces a stubborn paradox: the current impossibility of reconciling the rules of the quantum world with those of gravity, despite a century of efforts. This theoretical ...

A team of physicists has reimagined one of science’s most iconic experiments—but in the dimension of time. Researchers at Imperial College London have taken the classic double-slit test and turned it ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

As with many branches of physics and engineering, a common point of debate and research is: Under what conditions do the classical laws and theories of physics break down and quantum theories are ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Let me tell you about my book "Fields and Their Quanta: Making Sense of Quantum Foundations," published last year by Springer. It's technical, but I'll describe it in English. Scientists agree the ...

Sometimes, science doesn't result in new gadgets or medical breakthroughs, it simply helps us understand how truly strange our universe is. That was the case when physicist Lu Li and his team of ...

Batteries could charge up by relying on a quantum effect known as indefinite causal order, whereby the laws of cause and effect are scrambled and power can move through the system quicker. When you ...
