Well, we got a selfie. Next – the film.
They will try to expand the number of telescopes on the Earth’s surface so that they have another opportunity to reflect this black hole in more detail and others in sufficient detail to capture motion.
Basically, the exposure time was long enough for the movement around it, the gas spinning around this black hole was blurred. It’s like shooting a waterfall in a temporary exposure.
So, having a few more telescopes on the Earth’s surface, they should be able to freeze the action and make movies. And then, perhaps someday, they hope, we will be able to put interferometers, such paired telescopes, into space, which of course will be much farther apart and which will create a much larger lens practically, and who knows what we will let’s find out then.
