There are people that can't believe the Earth is round... I can't imagine what "alternative explanation" will be made to explain a black hole...
? As you can obviously see in the image, the black hole is also flat.

#52One difference between a Tesla or Apple style event vs a staid, scientific one such as this. Starting in the evening vs 9am...
Isn't that related to the fact that it has been announced across the world at the same time? In europe it was announced at 3 pm for example. I'm sorry, I don't understand your point

#53Related video, made by Veritasium yesterday, is one of my favorite videos in a long time. He explained how the prediction of this image was made (before the image got released) and the video is great and fun to watch. https://www.youtube.com/watch?v=zUyH3XhpLTo
Note that the prediction of the light being brighter on one side did come out.
What are you basing that on? (Edit:) From one of the papers released today:
> The ring is brighter in the south than the north. This can be explained by a combination of motion in the source and Doppler beaming. As a simple example we consider a luminous, optically thin ring... Then the approaching side of the ring is Doppler boosted, and the receding side is Doppler dimmed...This sense of rotation is consistent with the sense of rotation in ionized gas at arcsecond scales ..Notice that the asymmetry of the ring is consistent with the asymmetry inferred from 43 GHz observations of the brightness ratio between the north and south sides of the jet and counter-jet

(Edit 2:) Ahh, I see your comment now says "did come out". I initially read it as "did not come out", which was either a misreading on my part (likely) or an earlier edit by you.

#54I wonder how it compares to the one from Interstellar? https://www.newscientist.com/article/dn26966-interstellars-t...
This blog post describes the stuff Interstellar mostly gets right, and the big thing it's lacking (a brightness asymmetry from the rotation of the accretion disk). http://blogs.nature.com/aviewfromthebridge/2017/03/28/imagin...
If I recall this correctly, the movie intentionally simplified the rendering of the black hole (by eliminating the Doppler shift) to make it more visually appealing.
Pity, really. Then again, there were other things that made no sense in the movie...

Does that image have a weird pulsing optical illusion for anyone else?
Some time ago I've seen a picture over the Internet where the description said the more you see it "moving" the more likely you're stressed.
As for the black hole, looking it at full screen I see it pulsating a little.

#56Any word if Einstein's predictions are correct or refuted? There was word that if the shadow looked a certain way it could mean that relativity is incomplete.
In the discussions they said that it appeared entirely consistent with GR. Presumably more specific analysis is in papers coming afterwards.

Since we're on it, there's actually a book about the science of interstellar.

#58The EU is finally learning from the US when it comes making a lot of fanfare for discoveries and other inventions.
Too bad they don't present it well. I just see self congratulating politicians and officials on some youtube stream.
Telling that it's a US organization that hosts the actual picture.
esa.int and eso.org seem to be down actually.

I don't even have to move my eyes, I stare at it and it's constantly moving away from me. I had to check that it's not actually a movie. Strangest thing.
