Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing group of physicists is treating it as a possible glitch report from the fabric ...

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the ...

In a development at the intersection of quantum mechanics and general relativity, researchers have made significant strides toward unraveling the mysteries of quantum gravity. This work sheds new ...

In that shift, gravity stops being just a classical field and becomes a candidate “status report” from the underlying code. I see this as a subtle but important reframing: the simulation idea is no ...

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...

Gravity may not be a fundamental force of nature, but a byproduct of the universe streamlining information like a cosmic computer. Reading time 3 minutes We have long taken it for granted that gravity ...

Warp drives are staples of science fiction, and in principle could propel spaceships faster than the speed of light. Unfortunately, there are many problems with constructing them in practice, such as ...
