In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a striking concept in a 1935 paper. In that work, they described an abstract ...

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 proposed a modified version of Einstein’s general relativity, called quadratic quantum gravity (QQG), that could eliminate the Big Bang singularity and naturally produce cosmic ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

Professional physicists, especially quantum physicists, were not much interested in the rumored coming of Einstein’s new field theory. They had made a decisive turn shortly after the Solvay Conference ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

The year 2025 marks the 100th anniversary of the birth of quantum mechanics. In the century since the field’s inception, scientists and engineers have used quantum mechanics to create technologies ...

Add Yahoo as a preferred source to see more of our stories on Google. Einstein–Rosen bridges are not wormholes but quantum links between opposite directions of time, offering new insight into black ...
