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 ...

Ever since Einstein: nothing is faster than light. In 2011, an experiment at CERN seemed to prove the opposite - until the ...

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 ...

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 ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

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 ...

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 ...
