Why this is a big deal: Testing Einstein near a supermassive black hole

It’s all about the precision of the experiment, which is a function of the instruments used and the object being investigated. I highly recommend you to check out the source link below. As they write there:

Observations made with ESO’s Very Large Telescope 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. This long-sought result represents the climax of a 26-year-long observation campaign using ESO’s telescopes in Chile.

There is a lot more actual science to be had there, so again, check it out. 🙂
