A star will soon zip by the Milky Way's supermassive black hole at nearly 3% the speed of light. The star, named Source 2, was recently shown to lack a binary companion, meaning it will be used to further test Einstein's Theory of General Relativity. astronomy.com/news/2018/0…

Astrophysicists have devised a way to use the shadow of a supermassive black hole to test and rule out novel theories of gravity. The shape of the first black hole image provides the most precise match yet to certain predictions from general relativity, researchers report. sciencemag.org/news/2020/…

I'm tired of playing card games with rudimentary addition and subtraction of numbers. When is Artifact going to print cards that require fourth dimensional calculus or cards to test your understanding of the general theory of relativity? I want a whole set designed around rigid body dynamics

Fking hell. Why does every card's effect gotta be +1 this or +2 that.

Only that Maelwrawn card requires multiplication.. and that too of the number 2. By itself.

🀯

I think Artifact's design caters only to casuals who've barely finished third grade..

Mensa International demands a greater challenge!!

AskScience AMA Series: We have made the first successful test of Einstein's General Relativity near a supermassive black hole. AUA!

We are an international team led by the Max Planck Institute for extraterrestrial physics (MPE) in Garching, Germany, in conjunction with collaborators around the world, at the Paris Observatory-PSL, the Universite Grenoble Alpes, CNRS, the Max Planck Institute for Astronomy, the University of Cologne, the Portuguese CENTRA - Centro de Astrofisica e Gravitacao and ESO.

Our observations are the culmination of a 26-year series of ever-more-precise observations of the centre of the Milky Way using ESO instruments. The observations have for the first time revealed the effects predicted by Einstein's general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the centre of the Milky Way. You can read more details about the discovery here: ESO Science Release

Several of the astronomers on the team will be available starting 18:30 CEST (12:30 ET, 17:30 UT). We will use the ESO account* to answer your questions. Ask Us Anything!

*ESO facilitates this session, but the answers provided during this session are the responsibility of the scientists.
