Post a coin with orange peripheral toning and a black center? Or post whatever you like. I just thought this was awesome.

    I saw that.....
    Really incredible !
    just as amazing is the fact that Einstein predicted it and could have never seen anything like it.

    Terrific capture. Imagine the zoom on the Event Horizon Telescope. Nothing like it.

    One small area of confusion in the Times article: interior to the event horizon, matter-energy, space-time do not vanish from existence; we simply cannot observe them.

    We know the speed of light changes with the media through which it propagates. Although we can't directly observe it, I wonder what the speed of light is within a black hole, or just interior to the event horizon? Hawking postulated information content exists at the event horizon, but we really don't understand how to interpret or retrieve it. Further, does matter-energy continue to compress as in stellar cores; are their "layers"; is a black hole actually a singularity similar to a monopole, or is there another side -- a sign saying "This Way to the Egress?"

    I wonder how many radio telescopes and all their information was processed to produce what they think they see? I think the French have a different term for the astronomical term so as not to confuse it with something else.

    One way to think of a Singularity ("inside the black hole event horizon") is not that space-time and matter-energy, and gravity and the nuclear forces and everything and everyplace "disappear" nor is it that they are merely not observable anymore, but that they all sort of collapse into themselves and each other. There is no "there and then", thus no speed (distance/time) and no light (no waves, no photons) and no organization or information.

    Black "hole" is probably an unfortunate word choice. Its not a hole: Singularity captures the concept much better when thought about as a region of practicality Infinite density.

    The EHT has resolution that could be expressed in terms of spotting the date on a Washington quarter in the grading room at PCGS in California from the steps of the Washington Monument in D.C.

    edit to add this cool GIF of a Hubble Pixel resolving to the EHT's image of the black hole.

    It is an image.
    It is composed of data from direct observations; Just not from electromagnetic waves from the visible spectrum as in this image courtesy Corey S. Powell...

    This link has the research papers from this observation, which describes all this. Beware, it is complicated! Just getting the image is complicated enough, to interpret you also have to account for the light being highly bent around the black hole in question.

    I'm sure this is a very exciting time for astronomers. And I have been active in astronomy, more the visual and historical aspects for over 40 years. A local observatory sends out broadcasts to keep the hobby at a fever pitch. Relevance?

    Well I think that black holes are an incredible awesome force of nature. And until about 2 years ago, they were really still a theoretical concept. There was evidence for them, but it was not necessarily 100% rock solid. And now we have detected gravity waves from some, and now we SEE one! (Well, around it. It bends light completely around it I think.)

    Like logger7 said, this has been an amazing few decades for astronomy. I got my degree in physics, and was always interested in deep theoretical stuff, and the great discoveries since I graduated have been in the sky.

    Don't be too disappointed the image is blurry. It did take a telescope the size of the Earth to get enough resolution to see anything at all, which seemed completely impossible not long ago. They are pushing the optical limits a bit!

  • kbbpllkbbpll Posts: 542 ✭✭✭✭

    And almost exactly 100 years since they proved Einstein's prediction of the bending of light due to the sun's gravity, during the May 29, 1919 total eclipse. Not exactly photographic plates this time, but cool to have another "photographic" verification of Einstein's General Theory, 100 years later.

    I suspect that if @JoeyCoins and @ricko were around at the time, they would not have been impressed by the first light of Galileo's telescope either. ;)

    The image is composed of radio wavelength data, not optical data.

    The picture is a symbol - an analog - for what we don't yet understand.

    For fun, the image that rocked the world 100 years ago.
