The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

The detection of gravitational waves in 2015, caused by the merging of a pair of black holes 1.4 billion light years away, reminded us of the strength of Einstein’s theory of general relativity, which ...

Quantum cosmology and loop quantum gravity constitute two intertwined pillars in the quest for a quantum theory of gravity. Quantum cosmology applies the principles of quantum mechanics to the entire ...

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 ...

We do not live in the real world. This is the hard lesson that quantum theory would teach us. It is a theory that, to our way of thinking, makes no sense. Einstein was deeply suspicious of it – as he ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ongoing quest for quantum gravity. These findings, which involve the behavior ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...
