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 of general relativity — the idea that gravity is matter warping spacetime — has withstood over 100 years of scrutiny and testing, including the newest test from the Event Horizon Telescope collaboration, published today in the latest issue of Physical Review Letters.
According to the findings, Einstein’s theory just got 500 times harder to beat.
Despite its successes, Einstein’s robust theory remains mathematically irreconcilable with quantum mechanics, the scientific understanding of the subatomic world. Testing general relativity is important because the ultimate theory of the universe must encompass both gravity and quantum mechanics.
“We expect a complete theory of gravity to be different from general relativity, but there are many ways one can modify it. We found that whatever the correct theory is, it can’t be significantly different from general relativity when it comes to black holes. We really squeezed down the space of possible modifications,” said
