In it, he suggested that gravity is not a force, as Newton had believed, but the result of a curvature of the space-time continuum -- the four dimensional world in which we live. He used a thought ...

Starting with a precise formulation of the theory, including the necessary differential geometry, the authors discuss the significance of space-time curvature and examine the properties of a number of ...

The search for quantum gravity has gone on for 100 years, but it is not the only unification challenge in physics. Many of us ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger ...

But a team of researchers has just found that the predicted curvature of space-time ... They specifically measured the distortions of space-time due to gravity wells, at four distinct epochs ...

Avi Loeb explores how experimental quantum gravity may one day help to connect the dots between quantum mechanics and general ...

Join distinguished astrophysicist Professor Luciano Rezzolla on this virtual journey into Einstein's world of gravity, with each milestone presenting ever more fascinating aspects of gravitation.

This is because when gravity warps space and time, it interacts with everything within the curvature whether it has mass or ...
