Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery quantum fields that govern particles, and gravity has stubbornly resisted ...

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team ...

Sound Judgment: “A lot of people didn’t use our products for protection, but for comfort,” says, Loop CEO Dimitri O (right) with cofounder Maarten Bodewes, “comfort that they get through control over ...

Quantum gravity seeks a consistent framework to merge the principles of quantum mechanics with general relativity, addressing the challenges of formulating a quantum field theory for the gravitational ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical. Isaac Newton was never entirely happy with his ...

File this one under "fun to think about, probably not changing your day job": a new study just dropped that suggests gravity itself might be the smoking gun that our entire universe is one big ...

A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with quantum mechanics. Physicists Mikko Partanen and Jukka Tulkki at Aalto ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

You might say it all started with a spot of hay fever. In June 1925, a young physicist named Werner Heisenberg retreated to the barren island of Helgoland in the North Sea, seeking respite from his ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...
