Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

This video summarizes quantum gravity, highlighting the conflict between general relativity and quantum mechanics. It examines how gravity is described by Einstein’s theory at large scales, while ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be ...

Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest ...

Researchers at the Indian Institute of Technology Bombay have proposed a new test to measure the “quantumness” of gravity after finding that conventional “quantum entanglement-based” tests may be ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating ...

The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...
