The Photography of a Black Hole

First photography of the supermassive Black Hole in the center of M87
Black Holes have finally been dragged out of the shadows.
For the first time ever, humanity has photographed one of these elusive cosmic beasts, shining light on an exotic space-time realm that had long been beyond our ken. 
"We have seen what we thought was unseeable," Sheperd Doeleman, of Harvard University and the Harvard-Smithsonian Center for Astrophysics, said today (April 10) during a press conference at the National Press Club in Washington, D.C.
I am not sure, what is supposed to have been proven by this picture?
It is a massive object and its center appears darker, but as I predicted for many years it is not black, but dark red due to the gravity-related redshift.
We know from General Relativity that time slows down in the proximity of a so called Black Hole until it comes to a complete standstill at the event horizon. From this follows that nothing can ever fall into a Black Hole, i.e. cross its event horizon, because all the time of the universe would not be enough for this to happen. This means no photon will ever reach the point of no return and disappear in it. Instead light escaping from the proximity of a Black Hole will be extremely redshifted all the way down to the lower end of the electromagnetic spectrum. And this is exactly what we see. The center of the alleged Black Hole is dark red.
Of course this effect is probably due to the low resolution of the picture, but if the resolution is too low to distinguish anything with certainty, then what are we supposed to see there?


  1. Considering the scale of the picture, I cannot see any evidence for an event horizon at all. M87 is the galaxy with the strongest magnetic field we know, so strong that it emits a jet into space far beyond the borders of this galaxy. So what we see in the pgoto is exactly what we would expect at the center of auch a atrong magnetic field. There is no hint of a Black Hole.
    And why was M87 chosen in the first place, if this was about Black Holes and not about magnetic fields? There are other super-massive Black Holes far closer to us. They are cheating the public in the interpretation of this photo. It is not the Black Hole we can see here, but ionized matter orbiting the center of a massive magnetic field, whatever it may be.

  2. Correction: I did some math to verify the claims. If the scale of the image that has been provided is correct, the dark area would have a diameter of 300 AU, which is roughly equivalent to the calculated Schwarzschild radius of 130 AU of the M87 Black Hole. Therefore the image is indeed a strong evidence that the dark area reflects the event horizon of this object.
    We cannot tell from the photo what is going on at the event horizon, but it has to be a Black-Hole-like object that we are seeing here.
