We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

The findings resolve a long-standing problem in fundamental physics. Scientists at Hiroshima University have created a practical and highly sensitive method for detecting the Unruh effect, a ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a ...

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 ...

Ten years ago, astronomers made history when they first detected ripples in spacetime, called gravitational waves, from the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Einstein proposed and published his theories of special and general relativity in 1905 and 1915. The concepts are monumental ...
