In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

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, ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

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 ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. When you purchase through links on our site, we may earn ...

Theoretical physicists have proposed a potential solution to one of the most puzzling problems in modern physics: the black hole singularity paradox. By modifying Einstein's theory of general ...

It might not be obvious to those of us only grappling with more mundane concerns, but for cosmologists bent on unlocking the universe’s deepest secrets, there’s no shortage of problems keeping them up ...
