For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny ...

An analytical overview of recent studies suggesting that tiny, quantum-scale wormholes may be responsible for the universe’s ...

Instead of the big bang, some physicists have suggested that our universe may have come from a big bounce following another ...

Two decades ago, scientists found that the Universe’s expansion is accelerating. This was the complete opposite of what had been expected: the expansion should be slowing down due to gravity ...

A theoretical physicist in England has won a prestigious award for her work on the theory of massive gravity, which could explain why gravity hasn’t constrained the rapid expansion of the ...

Space.com: A physicist says a "leakage" of gravity over cosmic proportions could well explain the mysteriously accelerating expansion of the universe.

In a new study, the team describes how the space-time curvature — in effect, gravity — provided the stability needed for the universe to survive expansion in that early period.

Gravity-lensed supernova magnifies understanding of universe The new supernova is a Type Ia specimen. This supernova remnant, found in the Milky Way and called G299, is what was left over after a ...

The theory that the accelerated expansion of the universe is caused by mysterious "dark energy" is being challenged by New York University physicist Georgi Dvali. He thinks there's just a gravity ...

Measurements of the universe's expansion created by measuring the redshifted light of type Ia supernovas have resulted in a Hubble constant value of 73.2 kilometers per second per megaparsec.
