Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a ...

The search for quantum gravity has gone on for 100 years, but it is not the only unification challenge in physics. Many of us ...

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger ...

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not ...

For centuries, gravity has been one of the most captivating and puzzling forces in the universe. Thanks to the groundbreaking ...

To resolve the black hole, they used the Event Horizon Telescope, a global radio telescope array with an effective aperture ...

Extreme stars may possess mountains similar to those found on moons in our solar system, potentially creating detectable ...

The theory is a series of equations defined by Einstein. These equations combine space and time to create space-time. Gravity is explained by these equations, which are consistent with what we see ...

When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His ...

A mechanism for gravity is discussed in depth, which emerges as a quantum effect on quantum space-time within Matrix Theory. Using explicit examples and exercises, readers will develop a physical ...

Black holes have long captivated scientists and the public, embodying the mysteries of the universe. These celestial ...
