A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Plus, our experts explain the downsides to driving older modelsBy Mike MonticelloMain theme: In this podcast episode, we give ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

The early growth of the gas giant carved rings that formed primitive meteorites and shaped the architecture of the inner solar system. New research from Rice University reveals that Jupiter played a ...

The Big Bang purportedly transpired 13.8 billion years ago, and even so, the universe continues to expand even today. But if that thought alone wasn’t impressive enough, scientists also believe that ...

Physicists have long assumed that the universe is pretty much the same in any direction, and now they've found a new way to test that hypothesis: by examining the shadow of a black hole. If that ...

Some questions about the universe can quickly stray away from physics and into the realms of philosophy. What was before the Big Bang? Why is there something and not nothing? Happily some of the ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

Kyoto, Japan -- Having more tools helps; having the right tools is better. Utilizing multiple dimensions may simplify difficult problems -- not only in science fiction but also in physics -- and tie ...

Astrophysicists have an idea that could help to solve two mysteries: the reason for the bizarre abundance of super-high-energy radiation shooting from the center of our galaxy and the identity of ...
