Next-generation black hole imaging may help us understand gravity better

Описание: The Event Horizon Telescope has given us the first images of the environment surrounding a black hole. A team of physicists is using these images to test different theories of gravity. They are looking for subtle differences in the images that could help us understand gravity better. The next generation of telescopes may be able to detect these differences, but it won't be easy. The team used a model of gravity that allows them to vary the behavior of gravity within some limits. They found small but clear differences between the various versions of gravity, but these will be hard to detect. The researchers conclude that the next generation of telescopes might make it possible to pick some of these up, but it won't be easy. Basic variability in the black hole will cause variations that are larger than the ones seen in these models.
