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 ...

Albert Einstein is arguably the most influential scientist of the 20th century. His general theory of relativity changed our understanding of space and time, becoming one of the two pillars of modern ...

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

Objects warp the fabric of spacetime like a weight resting on a trampoline, and the fabric’s curvature guides their movements. With this insight, gravity was explained. Einstein presented his general ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window into the universe’s most extreme events. These collisions not only revealed ...

Albert Einstein’s general theory of relativity has been wildly successful at describing how gravity works and how it shapes the large-scale structure of the universe. It’s summed up in a saying by the ...

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 ...

Scientists have discovered gravitational waves stemming from a black hole merger event that suggest the resultant black hole settled into a stable, spherical shape. These waves also reveal the combo ...
