Or maybe Takeshi Miyagi Miyazaki just fucked up in their radio analysis / interpretation of it. Also wtf do they mean by saying that the accretion disc is elongated? The EHT picture doesn't show the entire accession disc anyway.

Nope. There already already multiple independent reanalyses of the EHT data, all of the others found a result consistent with the published image. The most likely explanation is that Miyoshi fucked up his analysis, some of that is described here in that he forces to algorithm to recover structure on scales which aren't sampled. Does he show his result is repeatable with other codes? No. The EHT team did, with 3 different methods and it has been independently reproduced.

What the fuck do you think is in the picture of OP? What about the picture I just posted? It's a black hole leaving a trail of young blue stars behind it as it cruises through space. There are tons of images of gravitational lensing by black holes, x-ray ejections from blackholes, and other radiation created by them. You don't see the actual black hole because you literally can't, since the light is trapped but you can see it's effects around it.

you literally can't take pictures like this from so far away. You'd need a lens the size of the solar system. It's clear the entire thing is not real.

>>
>>16465987
>What the fuck do you think is in the picture of OP?
he still has a point. heavily inferred images are not pictures of the thing. unfortunately there is no clear dividing line between artificial and natural images; I, personally, would not even consider the false-color images of nearby objects like Mars as 'images of the thing'. an image is only something that shows what I would see with my own eyes. false-color and statistically constructed "images" are useful, but in this age of total distrust they should be called something else or at least clearly watermarked with "NOT A REAL IMAGE".
>>
>>16468332
>you don't have photos of exoplanets.
You'd be wrong then.

>>16468365
>an image is only something that shows what I would see with my own eyes.
That is a shitty definition. Your computer screen is showing you an image of this board, a completely artificial construction. It's still an image though.
What you propose would be stupid, as the information in the image file is no different if it was taken with a visible light camera or an x-ray detector. Both are stored as 2D image arrays, and can be shown graphically. They are just as real as each other.
The term you are looking for is true color.
>>
>>16456714
I was skeptical when both black holes were donuts conveniently facing us.
>>
>>16468365
So if we had the right type of sensors in our eyes to see radio waves you would be fine with it? Because it's technically possible to do. Mosquitoes see in infrared, will the images be real to them?

They need to presume it's real in order to justify their comic bookish space travel fantasy lives that were implanted in their brains by watching stupid children's cartoons and being unable to differentiate science fiction entertainment from reality.
Anyone who has passed undergrad level optics would know its fake, but that is a tiny minority of people, far less than 1% of the population. Everyone else will just 'trust the science' and presume its real just like they did with the black hole pic and the sausage pic and piltdown man and all of the other many hoaxes and lies that scientists are constantly playing on the seething masses of the uneducated general public

The retards are looking at this picture and thinking "of course there’s ring are you people blind?" They are not intellectually curious enough to find out HOW these images are generated to begin with. They imagine it’s like taking a photo of the night sky, just boost contrast / saturation with time-lapse photography to get nice colors etc. These electro telescope images aren’t "images" at all, they’re electromagnetic frequency data which are color-coded using advanced models to map frequencies to colors to generate the image. To get the OP’s image a tiny sliver of data was tweezered out of a massive jumble of background signal and the model tweaked until the desired ring was generated. Basically the image creators messed with it until the resulting image showed what they wanted it to show. The problem was that not only was signal-to-noise so low as to be no different from noise ("artifact") but also that the image creators had to break established models for color-mapping. It’s super advanced esoteric radio-imaging shit under discussion but I saw a good video on it here: https://youtu.be/ZlrTe1mi5EQ

Where did I say something wasn't real? I said it won't work, because the software is written for a totally different task. If you had the first clue what you talking about you would know that.

>>16472333
You claim to know what you're talking about but haven't even mentioned the word interferometry. You have no understanding.
>The problem was that not only was signal-to-noise so low as to be no different from noise ("artifact")
Completely false. Pick related shows the visibility amplitudes of the 2016 EHT results from 2016 as reported by Miyoshi et al., on the left is the signal to noise ratios. You can see that the different baselines have SNRs of up to a few hundred, particularly those that include ALMA. So no, it's not low.
Robitaille has no idea what he's talking about, he apparently hasn't even read the paper he's citing. He has never looked at the data, or any astronomical data, he has no idea how VLBI really works. And neither do you.
>also that the image creators had to break established models for color-mapping
Fucking lel. You don't like their colormap, stop the presses. This is proof that you are a pedestrian who has never worked in physics. Next you'll be complaining you don't like their fonts.

I think people would be SHOCKED to learn just how few actual “scientists” there are. I mean people who understand their fields from the basic theories on up to the theoretical level. The ACTUAL reason why skepticism is met with dismissal / hate instead of a response is because most people who claim to be scientists are no such thing. They have a certain baseline of knowledge but not a fundamental understanding. For example…
Skeptic claim “x”
Scientist: x has been proven wrong by experiment y where researchers tested it using the following formulation…and it also violates Whoever’s Law which was proven by z experiment in….
Scienceologist: you’re a science-denying crank
Notice that with an actual scientist and actual exploration of the issue is possible even if he is completely confident in his belief, and, in extension, is open to having his belief altered in light of new information. The Scientologist is more like a priest repeating canon law and is uninterested in debating it; to him, questioning the dogma is a moral failure.

I don't really reply or make threads anymore but Images like these have helped me out with some of the worst points of my life and even get comfortable with the inevitability of my own death. In the end we are products of this reality, I could ramble on about what makes this universe special like how matter won against anti-matter or all the unique properties that keep the universe stable enough to support us and what exactly it took for you to exist but don't forget how insignificant you and I are. Remember to be humble, It is a privilege to be alive, an unbelievable amount take existence for granted, most live day to day just completely unaware of how much they owe to just being alive. if you are feeling hurt about a girl leaving you or someone dying or maybe something made you trip in life like someone abusing you, remember that you are alive, born healthy and were born in the greatest century so far to be alive. Life is fleeting and there is a very good chance consciousness is a temporary state. Whether there is an afterlife or not both are equally terrifying. If you are ever in a rough spot remember to be kind to yourself and to others, most people will not return it but so be it. Expecting a reward through kindness defeats the purpose of kindness. remember that you are a gift not only to yourself but to others.
