I was watching the press conference where they explained the image. They were talking about how the yellow and red parts are the super-heated matter around it, matter that is traveling close to the speed of light. Interesting point that was brought up is that the bight part at the bottom is from matter that's rotating towards us, while the dimmer parts are from matter rotating away from us. It's interesting because this let the astronomers determine the black hole is rotating clockwise.The yellow/red parts are actually from something behind it.
That would be the black hole without the accretion disc.
It's also interesting to not that even if we looked edge-on at the accretion disc, we'd still see its underside and the upper side due to the light being bended by the black hole.I was watching the press conference where they explained the image.

While I think this is a fantastic step forward for science, and a pretty neat image, given the amount of hype around this, I wholly think this is underwhelming and unspectacular.and people call that boring or unspectacular.
During the press conference, they actually addressed the resolution issue. Essentially they are planning on getting a higher resolution picture by adding some more telescopes and incorporating new techniques.I was seriously expecting something high resolution, not a smear that looks like older x-ray photos.
Well... yeah. Black holes are so much stuff crammed in so small a place that the force of gravity is overcoming other forces that keep atoms from crunching together into a mass of neutrons. It's never been considered as a literal hole in space. When they were first theorized they were much the same idea as they are now, basically a star goes nova, collapses, and if the balances of masses and various forces work out, it goes crunch and that matter that was previously the volume of a star is now a very, very tiny volume (We have no idea what size, or even if it can be said to have a size at all. This is where the problem of the incompatibility between relativity and traditional physics crops up).Lol I don't know what people were expecting, but it looks exactly as I thought it would. It's not in the middle of a belch which I think is the more interesting part. That's how most black holes were viewed is with the energy expulsion along the axis. It's pretty cool you can see the warping along the event horizon.
So it's a shadow, they say? So black holes can cast shadows? I mean, they're collapsed stars so there's a physical, perhaps tangible mass there, and there's known rogue black holes just roaming through space, but still. That means there is something in there, it's not just a giant hole in space where nothing exists. Something's in there.
It really is groundbreaking though. It has once and for all proven the existence of black holes, and has proven Einstein's theories even more so. On top of that, it proved the efficacy of using the their telescope arrangement to see things unimaginably far away at a great resolution compared to other techniques, not to mention that getting a picture of this black hole is the equivalent to trying to get a picture of an apple on the surface of the moon from the earth in terms of its size. It's impressive, especially considering that the scientists are now planning on taking measures to get an even higher resolution photo. This was just a proof of concept if anything.but it's not something that is "OMG SO GROUNDBREAKING!".
