A bit of hope for the black hole fallen in despair.

I wonder how that's working out for him?

 

 

 

Pretty cool video, explaining black holes relative masses and sizes.

"Even more puzzling is the prospect of taking a colour picture of an object whose gravity is so intense that not even gravity can escape."

Que?

The colors are 'fake'. They seem to be just remapping microwave radiation levels and frequencies into a false color representation. Pretty standard visualization technique for large data sets. The fact they can sense the data at the level of detail is fantastic.

I was referring to the fact that gravity can't escape. Either a misprint, or new to me.

I understand now, good catch, hopefully a misprint. From a general relativistic point of view Newtonian gravity is a "fictitious" force. Saying gravity can't escape is clearly wrong.

Yeah, I saw it too. I'm sure it's a typo. All popular articles about black holes use the very trite phrase "not even light can escape"

A new comparison of that image with earlier Event Horizon Telescope data reveals that the brightest spot on the ring changes location, due to turbulence in the violent eddy of material around the black hole,

 

A couple of dated, but very interesting short videos on this subject:

Medeiros and others developed the PRIMO modeling system, which co-developer Tod Lauer says is a "new approach to a difficult task." That system used a type of machine learning that lets computers make rules based on large sets of "training material," AIS said. In this case, they had computers look at more than 30,000 pictures of black holes taking in gas. Doing that allowed the system to essentially fill in the blanks of what was missing in the 2019 image.

From a fuzzy orange donut to a, um, less fuzzy orange donut. And fake at that.

Will miracles never cease?

I'm beginning to hate these announcements of 'faked' 'AI' data zooms and sharpening.

"it is still a theoretical expectation and not an actual photograph of the supermassive black hole"

It's an image but not a picture of any existing supermassive black hole. It's an impression of what it might look like. It's not DSP, noise reduction or image enhancement. It's generated data designed to make us see something we invented, not what we can actually see is there.
