When gravity—an invisible yet ubiquitous force—bends and distorts light from distant galaxies, Earthbound observers get a ...

A strange “Einstein Cross” with an extra, impossible fifth image has revealed the hidden presence of a massive dark matter ...

We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even this formidable mind was perplexed by a grand scientific problem, one that ...

For more than two decades, astronomers have wrestled with one of the biggest mysteries in science: what is driving the ...

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

Astronomers have made a discovery that looks like something out of science fiction: a rare “Einstein Cross” with an extra ...

Ten years ago, science confirmed one of Albert Einstein’s most elusive predictions: the existence of gravitational waves. Now ...

Einstein’s theory of special relativity tells us that for a moving object, time passes more slowly than for a stationary ...

A team of international astronomers have identified a cosmic oddity unlike anything seen before: a galaxy bent by gravity into an Einstein Cross with not four but five distinct images.

From early experiments with lanterns to Einstein’s revelations about space and time, the speed of light has proven to be far ...

In a landmark achievement, astronomers have noticed light bending in an unexpected manner, one that doesn’t align with the predictions made by Albert Einstein’s theory of general relativity. This ...

Future gravitational wave observations will allow us to test more exotic scientific theories, and maybe even probe the ...
