Loop Quantum Cosmology (LQC) applies the non-perturbative techniques of loop quantum gravity to homogeneous cosmological models, yielding a quantum replacement of the classical big-bang singularity by ...

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 ...

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

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 ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein's general relativity. One explains the tiny world of particles; the other describes ...

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 ...

ABHAY ASHTEKAR remembers his reaction the first time he saw the universe bounce. “I was taken aback,” he says. He was watching a simulation of the universe rewind towards the big bang. Mostly the ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...
