For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...

On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.

How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light moves through space at a constant speed has supported some of physics’ most ...

While SpaceX’s Falcon family continues to demonstrate reliable reuse of its first stages and fairings, other launch providers are actively developing competitors. One such rocket in work is Relativity ...

The e-discovery company also moved to open up its gen AI aiR suite to user customization, and integrate with more data sources. E-discovery company Relativity announced Wednesday the upcoming launch ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

A research team proposes utilizing numerical relativity, a computational technique for solving Einstein's equations in high-gravity environments, to investigate the universe's origin. The approach ...
