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 ...

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

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 ...

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 ...

General relativity describes gravity not as a force but as the curvature of spacetime produced by mass and energy. Matter tells spacetime how to curve, and this curved geometry guides the motion of ...

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 ...

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 ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...
