Their observations line up with what Einstein's theory of general relativity predicts. Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter ...

The Dark Energy Spectroscopic Instrument (DESI) has made significant contributions to understanding the universe's structure over the past 11 billion years, confirming Einstein's theory of general ...

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

Albert Einstein’s prediction about how gravity behaves has been tested on a cosmic scale. Albert Einstein’s prediction about ...

A recent study in Physical Review Letters explores quantum effects on black hole thermodynamics and geometry, focusing on ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

The findings hint at limitations in explaining the Universe's accelerating expansion. Albert Einstein's general relativity theory has been a pillar of contemporary physics for more than a century.

At a singularity, the laws of physics as we know them suffer a complete breakdown. So such objects really shouldn’t exist.

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