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 ...

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

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

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

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

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science — one that shaped quantum mechanics, redefined human understanding of ...

One of the fundamental challenges of physics is the reconciliation of Einstein's theory of relativity and quantum mechanics. The necessity to critically question these two pillars of modern physics ...

Teaching relativity to a dog may sound like a hopeless mental exercise, but physics professor Chad Orzel says it actually makes the job of teaching relativity to humans easier. "It makes the whole ...
