| Apr 12, 2019 at 14:09 | comment | added | jormansandoval | I remind you that what we are seeing is not the hole itself ... but its shadow amplified as a result of the distortion of space time. | |
| Apr 12, 2019 at 14:08 | comment | added | jormansandoval | no Rob. I think that you think that when I talk about the ring of light it's what the image shows. no no no ... I am talking about the ring of light that is created at a distance from Schwarzschild's radius, which is exactly 1.5 radii. to that ring of light I am referring to. | |
| Apr 12, 2019 at 14:02 | comment | added | jormansandoval | that is my question. why can not you see the ring of light? | |
