At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

A groundbreaking quantum experiment conducted by MIT physicists has turned a major page in the long-standing debate between ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

(via Sabine Hossenfelder) Einstein completed his theory of general relativity in 1915 when he was 37 years old. What did he do for the remaining 40 years of his life? He continued developing his ...

Albert Einstein's theory of general relativity, which suggests that gravity is due to the curvature of space and time, is more than 100 years old. And it's holding up as researchers analyze the ...

Rather than tweaking Einstein’s theory to fit into quantum rules, they suggest flipping the script. Their model, called a “postquantum theory of classical gravity,” aims to rethink the deep ...

Therefore, Einstein’s gravity cannot be the ultimate theory of gravity. Indeed, it was not long after the introduction of general relativity by Einstein in 1915 that Arthur Eddington, best known for ...

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 ...

When so much of anything accretes into one small place in space, it may all eventually collapse in on itself creating cosmic ...

Was Einstein Right? Putting General Relativity to the Test. Clifford Will. Basic Books. New York, 1986. 296 pp., illus. $18.95. Einstein's theory of general relativity holds a unique position in ...

In his 1986 book, Was Einstein Right? Prof. Clifford Will, physics, Washington University in St. Louis, declared anyone who questioned Albert Einstein’s special theory of relativity to be a ...
