Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

Scientists propose a groundbreaking experiment using quantum computers and atomic clocks to test whether gravity alters the ...

The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would use gravity fields to precisely map the interiors and compositions of exoplanets and other celestial bodies.

Gravitational-wave detectors work (see diagram) by splitting a laser beam in twain. The two halves of the beam are then sent down separate arms, several kilometres long, that are oriented at right ...

Photons and normal, stable particles both fall as expected in a gravitational field, with Earth causing any massive particle to accelerate towards its center at 9.8 m/s 2.

Detect they did, in a first for gravitational probings at this scale. One of the golden balls (the “source mass”) was recorded wobbling the other sphere, ever so slightly. The team’s results ...

But if it falls up in a gravitational field, that changes everything. With a single experimental result, artificial gravity would suddenly become a physical possibility.

A study suggests the maximum human-survivable long-term gravitational field is approximately 4.5 times Earth's gravity, based on calculations of bone compressive strength and an Icelandic ...
