Don't get me wrong. I am not saying it is not legit.
I am just saying that they have made a big show which is misleading. The discovery may be very significant for the scientific community who have the background to understand and interpret but they made a big show to present it to the general public and it is misleading because the general public has no idea of the meaning of any of all this. Most people on the street will think that is what a black hole actually looks like.
The purpose of this presentation and all the fanfare surrounding it is to gain exposure for themselves and their work and garner support and funding.
Pretty much like the launch of any Apple product: carefully anticipated and choreographed so as to get max exposure in the news.
But that is what a black hole actually looks like. In fact, from what I have read of one physicist who does simulations regarding how a black hole would look like if you could just look at it, it was almost a bit of a let-down because the simulations, based on general relativity and all that, are apparently so spot-on. I.E., the image didn't show them anything they didn't already know as far as knowledge of current physics, just confirmed it. They didn't go, "Oh wow, now this is something new, we didn't know that THIS is how black holes actually look," instead it was, "Yeah, that's EXACTLY how the simulations we run say it should look." The team that produced the image consisted of multiple separate teams that utilized different methods so that there would be no confirmation bias, and they all got the same result. Then they tried to find ways to "break" the image produced, if-you-will, and couldn't do it.
A black hole looks like a sphere of blackness, with the sphere's shape warped somewhat due to the force of gravity and how it bends the light as it travels. That is exactly how this black hole came out. Normally they are very hard to see because space is generally dark where they are, but this one was of a black hole earlier in its life with a lot of light around it, thus allowing them to be able to image it.
