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 ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

Google claims to have achieved a verifiable quantum breakthrough with a new algorithm that outperforms the most powerful ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Quantum physics is no longer confined to cryogenic chips and vacuum chambers. It is starting to seep into the machinery of ...
