It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? PBS Space Time is available to ...

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

At Aalto University in Finland, two physicists believe they may have cracked a puzzle that has defied generations of scientists: how to reconcile the physics of the very big with the physics of the ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

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 ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

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 ...
