Astronomers didn’t expect to see a thin disk around the supermassive black hole at the center of galaxy NGC 3147, some 130 million light-years away. They’re using Einstein’s theories of relativity to understand the velocities involved, and the intensity of black hole’s pull.

Star Orbiting Massive Black Hole Lends Support To Einstein’s Theory
Observations of light coming from a star zipping in orbit around the humongous black hole at the center of our galaxy have provided fresh evidence backing Albert Einstein’s 1915 theory of general relativity, astronomers said on Thursday. From a report: Researchers studied a star called S0-2, boasting a mass roughly 10 times larger than the sun, as it travels in an…
Einstein’s Theory of Relativity Holds Up Around a Supermassive Black Hole
Astronomers have shown that Einstein’s ideas about the warping of space and time holds true as the best description yet of how gravity works. Source: https://www.livescience.com/66031-einstein-relativity-works-around-black-hole.html
Supercomputer shows ‘Chameleon Theory’ could change how we think about gravity
Supercomputer simulations of galaxies have shown that Einstein’s theory of General Relativity might not be the only way to explain how gravity works or how galaxies form. Source: https://phys.org/news/2019-07-supercomputer-chameleon-theory-gravity.html…
Success with a new theory of gravity
Supercomputer simulations of galaxies show that Einstein’s general theory of relativity might not be the only way to explain how gravity works or how galaxies form. The new Chameleon Theory is a possible alternative. Source: https://earthsky.org/space/chameleon-theory-gravity-alternative-general-relativity…
Astrophysicist Tries Machine Learning To Generate a Black Hole Movie
One of the scientists who worked on the black hole picture is now pursuing an even more ambitious visualization, this time for the super-massive black hole at the center of our own galaxy. Long-time Slashdot reader Esther Schindler shares this report from Hewlett Packard Enterprise’s Insights blog: Lia Medeiros, a physicist, astrophysicist, and National Science Foundation fellow, is working to put…
What Is Relativity?
Albert Einstein was famous for many things, but his greatest brainchild is the theory of relativity. It forever changed our understanding of space and time. Source: https://www.livescience.com/32216-what-is-relativity.html
Today in science: Einstein’s triumph
May 29, 2019, is the 100th anniversary of a total solar eclipse, during which Sir Arthur Eddington observed the bending of light around the sun, thereby proving Einstein’s general relativity theory and catapulting Einstein into rock star fame.

Clocks, gravity and the limits of relativity
A hundred years ago today, Einstein’s theory of gravity was first put to the test when Arthur Eddington observed light “bending” around the sun during a solar eclipse. A century later, scientists are still searching for the limits of the theory. Source: https://earthsky.org/space/clocks-gravity-limits-of-relativity…
100 years ago, an eclipse proved Einstein right. Today, black holes do too — for now
In 1919, an eclipse affirmed Einstein’s famous general theory of relativity. Now scientists hope to use black holes to poke holes in that idea. Source: https://www.sciencenews.org/article/1919-eclipse-photo-einstein-black-holes4…
