"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

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

One of the most impressive things about Einstein's 1915 theory of gravity, general relativity, is just how many incredible cosmic objects its central equations have predicted.

Since the beginning of the 20th century, Einstein's theory of general relativity has been the best description we have of how gravity works. However, right around when Einstein came up with ...

Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency ...

Score one more for Einstein. A new study has confirmed histheory of general relativity works on extremely large scales. The study was one of the first rigorous tests of this theoryof gravity ...

If general relativity matched LIGO's measurements when pi was not close to its true figure, that would be a sign that the theory was only half-baked.

And yet his famous equations struggle to fully explain such objects. While general relativity says a strong source of gravity — like the sun — will warp the fabric of space, bend light from a ...

One might wonder why, exactly, a theory of gravity is called a “general theory of relativity.” Well, Einstein began to use this title before the theory was complete.

According to the modified gravity theory, an offshoot of MOND, a black hole's shadow should be ten times larger compared to what general relativity predicts. The Event Horizon Telescope aims to image ...
