Is there zero gravity on the ISS? Here's how it works

Photos and videos of astronauts on the ISS show them floating around, but saying there's zero gravity isn't fully accurate.

Alternative gravity theory offers possible explanation for dark energy changing over time

For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is ...

Emergent gravity may be a dead idea, but it’s not a bad one

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...

Scientists observe Einstein’s gravity in the quantum world for the first time

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s ...

Gravity: the well of spacetimeliness

Ever since Newton published his universal law of gravitation in 1687, anyone with a slide rule and a half decent education could calculate the force of gravity on a falling body or a planet in orbit.

Einstein’s equations offer new clues to extreme gravity and space-time behavior

A theoretical study describes how gravitational field structures could change their connections, drawing on methods used in ...

Gravity and quantum information linked through a derivation of Einstein's equations

Recent research shows that gravity and quantum information are deeply connected and that the shape of spacetime can be traced back to the way information is stored in quantum fields. Einstein's theory ...
