A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity ...

A new study published in the journal PRX Quantum demonstrates how a network of quantum computers employing optical clocks can ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings.

Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts ...

The second, integrated information theory, takes a more globalist view. The idea is that consciousness stems from a series of cause-effect reactions from the brain’s networks. With the right neural ...

Einstein's Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation of how the universe ticks.

Einstein's theory of general relativity called the weak equivalence principle, which states that all objects, regardless of their mass or composition, should free-fall the same way in a particular ...
