Not those kind of black holes
Gravitational extremes that previously we're believed to break the laws of physics and previously believed to be a singularity.
There is an angle they could have used that would produce a much clearer picture. It's not inescapable like previously believed. if you send the light/radio at the right angle it'll fling the particles/waves around and out if it's orbit far away faster than it can pull back on them.
The sling shot they used was one of the angles they should not have used as it teaches us as much as the one from interstellar gave us. For proof of concept I'll take it, but they hyped it up so much and gave us garbage they know better than to give us with that level of hype. Fail. Just admit you guys fucked up and need to try again. Half the frustration is because they're not admitting they fucked up and need to try again
The only thing it is is a proof of concept. That's it. Nothing more. It's sad they hyped up a POS test shot.
I've followed every single piece of news about this since they were talking about doing it. I've watched all the documentaries also.
The truth is they were ashamed of the photo and instead of trying again they hid it for a year and a half from us whole telling us we whole time how awesome it'll be when they finally process the data. Especially when they themselves are on camera saying that they've done test runs to make sure they could do this at all and that the only thing they need to do is bring the petabyte hard drives to one location, compile the information in one chunk, and then the image was going to be visible to the public within a few weeks.
They already were flying all the hard drives to one location at the time of the filming including showing the drives themselves on camera. The documentary came out in 2017. It's 2019 now.
