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

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

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 ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

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

Time seems simple, but modern physics suggests it may behave in ways we barely understand. From relativity to strange experimental results, scientists continue exploring whether time always flows the ...

Without AI computing power support and the Congzi equation, human consciousness uploading will completely lose technical feasibility and continuity guarantee, becoming an inoperable "digital relic".

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist Dan Kasen. Kasen and his colleagues hypothesized that at least some ...

Interstellar travel captures the imagination, but the laws of physics impose severe limits on what is possible. Einstein’s theory of relativity sets a cosmic speed limit that prevents anything from ...
