110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

Sophia Varughese has two passions: astrophysics and music. Her senior thesis is a scholarly look at black holes and ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating black ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...

A peer-reviewed paper published in The European Physical Journal C presents a modification to Einstein’s general relativity that eliminates the singularities associated with the Big Bang and Big ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...

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 ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

A newly developed solution to the equations at the heart of Albert Einstein's most revolutionary theory suggests hypothetical stars called "nestars" could be made from stacked gravitational stars, or ...

Albert Einstein's famous relativity quote, "When you are courting a nice girl an hour seems like a second. When you sit on a ...
