    I Black hole image: What are those "lobes"? [M87 10April2019]

    Complex rotations. Yes. All very interesting, (as are so many new scientific observations). PS I also like the Veritasium YouTube video on the subject, in case you're interested. Worth watching.

    I Black hole image: What are those "lobes"? [M87 10April2019]

    "ambient emissions" isn't a term I've heard, nor what the video describes. I'm wondering if it's something not simple? Maybe some other asymmetric blobs of matter (ya I know, that's even less of a technical term! Lol) that is emiting comparatively fewer syncrotrons? And will the orientation of...

    I Black hole image: What are those "lobes"? [M87 10April2019]

    Ok here I have highlighted the faint lobes outside the main ring ... What do you think? They are not 'nothing'... , so therefore what are they from? fascinating! Cheers.

    I Black hole image: What are those "lobes"? [M87 10April2019]

    Hi and thank you! Yes I watched the video but despite the elegant descriptions, it did not address my question about what I see in the image... I will try to attach a annotated copy of the image here. Brb...

    I Black hole image: What are those "lobes"? [M87 10April2019]

    Hmmm. R i g h t ... And what do you suppose we call a packet of energy from those “very long way below visible light wavelengths”? A photon. My paste alluded to photons. No one here thinks that we are using classical photography of visible wavelengths of photons to capture it. I do hope...

    I Black hole image: What are those "lobes"? [M87 10April2019]

    oh i understood that the ring in the image was the photon sphere, at approx 2.6 Schwarzschild radii: --paste--- The edge of the shadow is due to the photon sphere - the radius at which light goes around in closed orbits. If a light ray coming in at an oblique angle just skims the photon sphere...

    I Black hole image: What are those "lobes"? [M87 10April2019]

    Hi Jarvis, please see my reply to Dave. What I meant in my original message is that it seems unlikely that a science team of this pedigree, and with this sophisticated processing at their disposal, plus the scrutiny they surely knew the image would undergo, would leave processing artifacts or...

    I Black hole image: What are those "lobes"? [M87 10April2019]

    Hi. I should have made my question more clear. The “lobes” I’m referring to (for lack of a better term) are quite faint but not ‘zero data’. The lobes at four and eleven o’clock are actually the brighter lobes (you referred to them as “those fainter areas”). The ones at three and nine are the...

    I Black hole image: What are those "lobes"? [M87 10April2019]

    Lobes Did anyone hear an explanation of the appearance of the lobes visible in the published image? I only caught part of the Q&A. (Visible most prominently at at eleven o'clock and four o'clock positions, and to lesser degree at three and nine) Do these type of observations generate "lense...

    Light speed travel (now "understanding the difference between weight and mass")

    Mass is how much stuff is inside an object (matter). Even a "weightless" astronaut is made of matter and has mass. (Same goes for a grain of sand deep in interstellar space) If you are up there with him and you give him a shove, it requires energy, and you and he start moving apart with...
