Without the black holes, our universe would probably be completely different. It is even possible that the formation of galaxies is due to black holes.


The fact that the black holes do not allow the light to come out makes them difficult to observe. Scientists are looking for a ring of light around a dark area that is a real black hole.

The stars disintegrate or merge with each other. Their mass condenses at only one point with extremely strong gravity. The end result is a black hole.


Maybe you didn’t know this but even the Milky Way has a black hole. Scientists believe that there are such in every galaxy. When two galaxies get close enough to each other and combine into one, the black holes merge. A spectacular collision.

Is this process going on indefinitely? A question we can only answer theoretically.

How do we know that black holes exist?

Unlike planets and stars, black holes have no shape or surface. Rather, they are gigantic spaces, engulfing everything in their vicinity. Black holes divert light and stars from their orbits, squeezing them, lubricating them, pulling any matter, and engulfing it like a vortex in its dark abyss.

Scientists can measure these deviations. And they know that these are black holes of incredible size and immeasurable power.


How do they form?

Black holes occur in many different ways. For example, in stellar explosions, called by scientists Supernova. Black holes can also occur in the collision and subsequent fusion of two stars. If the mass is particularly large, this new star can collapse and turn into a black hole.

In addition, there are the so-called supermassive black holes. They are the largest type of black hole and weigh between hundreds of thousands and billions of solar masses. Most galaxies, including the Milky Way, are thought to have a supermassive black hole at their center. Scientists still don’t know exactly how supermassive black holes came into being.

Which black holes are of particular importance to us?

Two black holes are especially important to us. They have been observed since 2017 by scientists from the international research project EHT.

One is called Sagittarius A – a supermassive black hole located in the center of the Milky Way. It is 26,000 light-years from Earth and weighs over 4 million solar masses.

The other black hole observed is the supermassive black hole in the giant galaxy M87 in the constellation Virgo. It is 55 million light-years from Earth and weighs 6.6 billion solar masses. It can be seen in the first photo of a black hole in history.

We have discussed black holes in previous articles, then why again now? This particular piece was influenced by an old video from 2014 which I found on YouTube. Simply said, it shows how massive black holes really are.


What makes it significant is the way this information is presented. The creator used attractive and interactive methods to give useful information in an understandable way using places and objects from our daily life.

If you thought that some regular things in life are scary, wait until you see how impressively powerful and eerie black holes are. Trust me and take 4 minutes of your time to watch this incredible video.
