Could a reactionless, gravity-defying propulsion system actually work? A former NASA engineer says yes, but scientists are ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

A team of physicists have discovered a new approach that redefines the conception of a black hole by mapping out their ...

Getting to outer space is tough, but living there presents a whole new slew if issues. Check out how astronauts accomplish ...

Then, there's the fact that Einstein's theory of gravity won't "play nice" with quantum physics. The new framework — or "recipe" for gravity, if you will — takes the metric of spacetime from ...
