A breakthrough wormhole simulation could unite quantum physics and general relativity

Scientists have developed a quantum experiment that allows them to study the dynamics of wormholes, theoretical entities of space-time from Albert Einstein’s theory of gravity in 1915, or general relativity. Rather than creating an actual wormhole, a rip in time and space that is theorized to bridge one distant region of space with another, the …

The cosmic test of general relativity disagrees with Einstein

Leave a Comment / Outer space / By admin

A new large-scale test of Einstein’s “general relativity theory” has raised questions about this cornerstone of modern physics. “General relativity” provides a powerful predictive framework for one of nature’s fundamental forces: gravity. The theory is remarkably successful in describing gravity when talking about stars and planets. But different physical scales present challenges for Einstein’s theory. …

Scientists Tested Einstein’s Relativity on a Cosmic Scale and Found Something Strange

Everything in the Universe has gravity – and feels it too. Yet this most common fundamental force is also the one that poses the greatest challenges to physicists. Albert Einstein’s theory of general relativity was remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly to all scales. …
