Science is not religion and contrarian opinions strengthen science results. I think it's healthy to always have a dose of skepticism, and is not uncommon for astrophysics papers to be retracted or refuted.

Absolutely, but those retractions are led by other astronomers/astrophysicists, not lay people presenting straw men. I think people's priors here are out of whack -- perhaps the truth does lie somewhere in the middle, but if so, it will be much closer to ETH's version than the OP's.

  Astronomers/astrophysicists started first, by misrepresenting the process and bringing the talk of taking photos and having "visual evidence". "...We have seen, and taken a picture, of a Black Hole." https://youtu.be/lnJi0Jy692w?t=456 https://youtu.be/lnJi0Jy692w?t=456

    Yes? He’s correct.

      There we go again...If you had a photo you not would need to make the merge of the four different images achieved by the four different teams. Now the you have published the data from 2017, If I publish my own "photo", and I chose blue with spots of white, using the same library you used and the same color maps: https://github.com/liamedeiros/ehtplot/blob/docs/docs/COLORMAPS.ipynb https://github.com/liamedeiros/ehtplot/blob/docs/docs/COLORM... Why yours will be more a picture than mine in blue? Maybe I will even splint a little bit of red in there...

        I’m looking forward to reading your scientific paper.

        And I am looking forward to have many other different teams reproduce your results independently. I also would like to notice you did not explain why my blue "picture" would be less a "picture" than yours.

        A picture of a black hole would be always artificial, for color don't really exist as it's only the brain interpretation of a part of the EM spectrum heavily averaged, that's why we don't see green stars even if there are many stars whose strongest light is green, like our own sun. Taking a real picture of a black hole like with a cellphone camera would likely be just like a bright white star.
