Unveiling the first-ever image of a black hole [video]
Good video that correctly predicted the image and describes why it looks the way it does [1].<p>TL; DR The dark area is the entire surface of the event horizon, including the side facing away from us, plus some more due to photons missing the event horizon &quot;directly&quot; being drawn in. One side is brighter due to its being Doppler boosted.<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=zUyH3XhpLTo" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=zUyH3XhpLTo</a>
