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 ...

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 ...

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".

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 ...

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 ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

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 ...
