That's what happened when physicists starting in the 1930s discovered quantum mechanics, which challenged

Einstein's general theory of relativity, and which eventually morphed into string theory in the 1980s (and yes, I'm simplifying here), which harmonized general relativity and quantum mechanics.

Rezzolla said that

Einstein's general theory of relativity is the best theory of gravity we know, but it is not the only one; he added that they will use these observations to find out if black holes, one of the most cherished astrophysical objects, exist or not, asserting that finally, they have the opportunity to test gravity in a regime that until recently belonged to the realm of science fiction; it will be a turning point in modern science.

However, the only conclusion that can logically be drawn from

Einstein's General Theory of Relativity is the universe grew rapidly from an unimaginably hot, dense state that was infinitesimally tiny the essence of the "Big Bang" theory.

Because [Albert]

Einstein's general theory of relativity does not choose a time orientation, if a black hole can form from the gravitational collapse of matter through an event horizon in the future, then the reverse process is also possible.

When I was first acquainted with Smarandache geometries many years ago, I immediately started applying them, in order to extend the basic geometry of

Einstein's General Theory of Relativity.

Over the decades, the orbit's long axis has been precessing (shifting direction) only one-fourth as fast as predicted using

Einstein's general theory of relativity.

Both of these two models are mathematical extensions of

Einstein's General Theory of Relativity.

It showed that the universe must have begun with a singularity, if

Einstein's general theory of relativity is correct.

Ferris takes

Einstein's General Theory of Relativity and in a few of pages offers what journalist Charles Krauthammer has described "as intuitive an account of its essential idea - the curvature of space - as I have ever read.

Basing his theorizing on equations that were part of

Einstein's general theory of relativity, Willem de Sitter claimed in 1917 that the Universe was expanding.

the leading innovator of Ethernet Fabric switching solutions based on its patented vSCALE[TM] technology for data centers and high-performance computing (HPC) clusters, today announced that the prestigious Max Planck Institute for Gravitational Physics (Albert Einstein Institute, Hannover, Germany) is using Woven's EFX 1000 10 Gigabit Ethernet (10 GE) Fabric Switch and TRX 100 Ethernet Switch in a large HPC cluster to search for gravitational waves predicted by Albert

Einstein's General Theory of Relativity.

In

Einstein's general theory of relativity, massive objects warp the fabric of spacetime, creating a gravitational pull and slowing time nearby.

Owen Sheers' script is lyrical and clever, weaving the past with the present day and seamlessly incorporating other aspects of news from the time, from the Senghenydd colliery disaster to Albert

Einstein's general theory of relativity.

Cox said that time travel to the future is possible under Albert

Einstein's general theory of relativity.

This technique takes advantage of

Einstein's general theory of relativity, which predicts that a massive object (such as a star) can gravitationally bend the light from a more distant star.
