The basic idea here is that there's a curvature in everyday sense as in bend a sheet into a cylinder, ... space(-time) fabric that the photon in Path A has to travel along, for a brief amount of time.

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe ...

“In the moment that you carve the space-time, you can play with that curvature to make the time come in a circle and make a time machine,” Alonso-Serrano told USA TODAY.

Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the ...

Space-time curvature around a black hole might sound abstract, but understanding it is crucial to grasp the nature of these cosmic giants. Using the Schwarzschild metric, we can model how gravity ...

Earlier this year, new research suggested a potential solution to one of the most troubling aspects of modern physics — that "singularities" seem to exist at the hearts of black holes. The idea of the ...

An artist's impression of Earth's gravity well. The idea that gravity is the result of the curvature of space-time is a core principle of Einstein's theory of general relativity.

Albert Einstein curved space-time to describe gravity, and despite still-open questions about dark matter or dark energy, it seems, today, to be the best method of analyzing the past and future of ...

Space-time is described by Albert Einstein's famous equations for general relativity. ... Wormholes could take advantage of that curvature of space, connecting different curved parts of space-time.
