The last 30 years of his life were spent on a fruitless search for a unified field theory, but as John Ellis explains, Einstein put this "holy grail" of modern physics on the theoretical map. The ...

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework built ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

In the present paper are introduced generalized Einstein spaces. Einstein type tensors are represented in the generalized Einstein spaces. Some relations of Einstein type tensors of the first and the ...

Albert Einstein on a bill of 5 Israeli Pounds. A truly spectacular unpublished autograph manuscript produced by German physicist Albert Einstein (1879-1955) and exploring his celebrated Unified Field ...

A Google Deep Mind researcher and physics expert, Adam Brown, discusses what an AI Einstein would be like. Einstein coming up with General Relativity required coming up with new notation. Einstein’s ...
