Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into the basic laws of physics but instead emerges from gravity’s effect on heat ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

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

A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

These universal constants include the speed of light in a vacuum, Newton’s gravitational constant, Planck’s constant (the scale at which quantum effects begin), and the masses of the fundamental ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

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 ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...
