What? You forgot your car keys. And you’re taking help of your family to find the key! Think about how many people were needed to find a thing which is many more trillions of miles away from us.
On April 4th, 2017, a privileged group of telescopes on mountains across the planet switched on at the same time. For the next week, they danced in unison, collecting radio waves dispatched from the center of our Milky Way galaxy and from the galaxy m87. Together they make up the event horizon telescope, a global project to capture the first ever picture of a black hole.

You ever saw the image of Blackhole was nothing but a delusion and description made by us. Ever since physicists first conceived of black holes centuries ago, every image of one from our textbooks and our space agencies, they’re all illustrations.
For centuries, physicists have theorized that an object with enough mass and density could trap even light in its gravitational field, just as you have to travel faster to leave Earth than you do to leave the Moon, there could be a place where you’d have to travel faster than the speed of light to escape.
Einstein always thought that there must be some physical mechanism that prevents stars from collapsing to an infinitely small point, which is actually pretty reasonable. I mean, because it sounds madcap.
Ultimately, scientists began to see things that only made sense if black holes were real, like the orbits of these stars around the center of the Milky Way galaxy.
You see these stars just slingshotting around an invisible point and a black hole is the most likely explanation for putting that amount of mass in that
small space, for something that’s completely dark.
The picture we see this week is made of scraps and bits of light that’s been traveling across the universe and collected by these, you know, aluminum dishes on top of mountaintops and then combined in a supercomputer to make this image.
Yes, it’s just the image, but this is nothing less than a milestone for us.
