First photo of a black hole supports Einstein’s theory of relativity

By Ashley Strickland | CNN | Updated 1:59 PM ET, Fri October 2, 2020 (CNN) The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein’s theory of general relativity. The new finding has suggested his theory is now 500 times harder to beat.Einstein’s theory, or the idea that gravity is matter warping space-time, has persisted for a hundred years as new astronomical discoveries have been made. Researchers from the Event Horizon Telescope collaboration, the team that imaged…

Putting the Squeeze on General Relativity

Analyzing the first image of a black hole in a nearby galaxy, researchers have provided quantitative tests of general relativity in the strongest gravitational fields yet. October 1, 2020 | Physics 13, s128 In 2019, the Event Horizon Telescope (EHT) released the first image of a giant black hole in the nearby galaxy M87. Revealing a circular shadow whose diameter was within 17% of predictions, the measurement provided a qualitative confirmation of general relativity while still leaving room for alternative theories of…

GLT Visit

In October 2019, undergraduate student Dalton Glove and Dimitrios Psaltis (Arizona) traveled to Thule, Greenland with Satoki Matsushita, Derek Kubo (ASIAA), and Nimesh Patel (SAO) to collect existing weather and radiometer data as well as install scripts to upload automatically future data on the online PIRE weather database. The ASIAA+SAO members focused on holographic measurements of the GLT surface and all worked on installing scripts for monitoring remotely the condition of the Maser on site).

4 things we’ll learn from the first closeup image of a black hole

Event Horizon Telescope data are giving scientists an image of the Milky Way’s behemoth BY LISA GROSSMAN 09:58AM, MARCH 29, 2019 We’re about to see the first close-up of a black hole. The Event Horizon Telescope, a network of eight radio observatories spanning the globe, has set its sights on a pair of behemoths: Sagittarius A*, the supermassive black hole at the Milky Way’s center, and an even more massive black hole 53.5 million light-years away in galaxy M87 (SN Online:…

Imaging black holes

01 APRIL 2018 The Event Horizon Telescope will combine data from a worldwide network of radio telescopes to image the shadow that a black hole casts on the surrounding plasma. Within months of the publication of Albert Einstein’s general relativistic field equations in 1915, Karl Schwarzschild had derived the equations’ first nontrivial solution—the black hole spacetime. Ever since then, the physics and astronomy communities have had a love–hate relationship with black holes. It took almost half a century before they…
