In search of a united scientific theory, a new quantum gravity paper might have proposed an interesting aspect that made the ...

Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, scientists have demonstrated time and time again how correct these theories are.

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...

George Musser’s new book finds resonances between the science of the latest wonder materials and string theory, quantum gravity, and the origins of space and time A new short volume by veteran science ...

Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

First up, just pointing a rocket at the Sun and blasting as hard as you can would result in a wild miss. The main problem you ...
