He isn't explaining why the blackhole would look like a fuzzy coffee mug stain. He's explaining why the _picture_ of the blackhole will look like a fuzzy coffee mug stain.

To your point, it's like taking a picture of Uranus with film and waiting for it to develop. People familiar with the matter can guess what the _image_ will look like not what Uranus actually looks like.

This is all very clear in the first 25 seconds of the video if you actually listen to what he's saying.

The first 25 seconds of this video actually does not have sound. The 25 seconds after he begins talking is him talking about Einstein and history.

Unless I'm misunderstanding your intentions and you just meant that as a condescending insult?

You're ranting about Saturn and Jupiter for some reason. Why don't you calm down and look at page eight of the paper that Veritasium video was based on: https://ve42.co/luminet "Image of a spherical black hole with thin accretion disk Astronomy and Astrophysics, vol. 75, no. 1-2, May 1979, p. 228-235"

Look at that last image, and squint at it until it gets fuzzy. Lo and behold, a fuzzy coffee mug stain!

Perhaps it was a mistake for him to make the focus of the video on the physics of black holes, rather than the limitations of state of the art radio interferometry... but I don't think so.

Really awesome link, thanks for that! It's always interesting to see theory that is decades out in front of experimental confirmation, and then proves to be dead right.

Yeah, I did a double-take when I saw that was published in 1979. I think that's really cool.

You truly believe that all of the downvotes on all of your comments are the work of one account?

Mate, you insulted me first, and have just repeated that insult again. I've tried to be charitable with you.

How did you come to the conclusion that I "insulted you first?"
