Astronomers from the U.S. National Science Foundation have managed to observe the black hole in the center of the M87 Galaxy in a way to prove it exists. This is considered the first concrete evidence of the existence of black holes.
The black hole of M87 is 40 billion kilometers long and 53 million light-years away from our Earth. The reason why the black hole in the center of another galaxy is preferred instead of the Milky Way galaxy is because the Milky Way is much larger than the Central Sagittarius A, and therefore slower moving.
To obtain this image, telescopes were used in different parts of the Earth.
What we see in the media frequently is that images like the following were completely simulated. For the first time in evidence quality, it was a real image.
Why is this important discovery?
contrary to what we think and expect, we have seen a photograph of the Milky Way galaxy, not the black hole in the center of the Galaxy in which we are, but another black hole.
What exactly was achieved?
it is not a black hole photograph, it is a photograph where we can see the shadow created by the black hole on the accumulation disc of the event horizon.
they say,” that shadow is already the black hole itself, don’t confuse it.” no, it’s not.
if we can visualize Hawking radiation, it’il give us the black hole’s event horizon.
the shadow that appears is actually covering an area of 2.6 R greater than the black hole’s event horizon. shadow is not a black hole then. in fact, the event horizon is not a black hole. the real black hole is the singularity point in this whole system.
it’s impossible to see the singularity in the event horizon. but one day it will be possible to view the surface of the event horizon immediately. only devices that we have now are not advanced enough to detect Hawking radiation.
although this photograph is impressive, it is not one of the oldest cosmic events in history.
NASA’s WMAP project between 2001 and 2010 mapped the remnant of the Big Bang radiation, and the following data from 13.8 billion years after the Big Bang could be called the image of the oldest cosmic event in history.
