While the ΛCDM model has been a cornerstone of cosmology, it is showing its limitations as researchers seek to explain observations beyond its scope. (CREDIT: ESO/L. Calçada/spaceengine.org) The ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

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 ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

Herman Mishkin’s 1921 photograph of Albert Einstein, signed and inscribed by Einstein (courtesy private collection) (click to enlarge) Celebrating 100 Years features a 1919 letter written by Einstein ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

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 ...

Einstein’s equations of general relativity were a wellspring from which our current view of the cosmos has flowed. That the theory continues to supply so many rich questions is part of what makes it ...

Add Yahoo as a preferred source to see more of our stories on Google. Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of ...

GENEVA - A pillar of physics - that nothing can go faster than the speed of light - appears to be smashed by an oddball subatomic particle that has apparently made a giant end run around Albert ...
