A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Many World’s lack wavefunction collapse might be the key to the measurement problem. The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem ...

The CMS and ATLAS experiments recently detected quantum entanglement between top quarks in high-energy collisions at the LHC. What does that mean? Quantum entanglement links subatomic particles in a ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...
