Earlier in 2019, an international team of over 200 scientists produced the fist image of a black hole. This was indeed groundbreaking news for science as black holes have remained a puzzle for decades which scientists have been trying to solve. This image, however, has confirmed their existence and will only result in further revelations.
So what are black holes? They are dark cosmic entities with gravitational forces so strong that no object, not even light, can escape from them. They were discovered by German Physicist Karl Schwarzschild in 1916 and have been a major subject of interest ever since.
Here are 7 amazing facts about black holes that will surely low your mind!
The Laws Governing Our Universe Do Not Apply TO Black Holes
Think of a world where the universal laws of physics don’t apply. That’s exactly what the internal region of a black hole looks like. If you were to fall into a black hole and you pass the events horizon – the boundary marking its limits and often called the point of no return – you’ll enter a world with a distorted horizon and where all the laws governing the universe no longer exist. Some scientists think that this is the end of space itself while some spiritual-minded people have presumed it to be the place we go when we die.
Yes, that’s a real word and it describes what would happen to you if you fell into a black hole. The gravitational pull in a black hole is so strong that if you ever fell into one, it will act on your body and stretch you until you resemble a strand of spaghetti and your body rips in half. Chills!
No Respecter Of Time
A common misconception about black holes is that they make time stop, yet what they actually do is slow down time.
They have hair
Before you get creeped out, black holes don’t have hair in the literal sense. John wheeler, the legendary physicist that coined the term “black hole” stated that “black holes have no hair”, meaning that they were simple in structure. Recent theories have, however, postulated that their structure is more complicated than were once believed.
The Milky Way Galaxy Has A Black Hole In Its Centre
A common phenomenon among galaxies, the Milky Way has a black hole in its centre. This black hole is called “Saggitarius A-star” and it is located about 20,000 light-years from earth.
The Largest Black Hole is 17 billion times the mass of the sun
This freak of nature is so large that it is the equivalent of 17 billion suns put together. In comparison, the Milky Way’s black hole is only equivalent to four million suns. This enormous black hole is located in the NGC 1277, a small galaxy about 250 million light-years away from earth.
Do Black Holes Die?
The answer is yes and no. Black holes radiate energy and shrink over time until they vanish completely. This phenomenon is called Hawking radiation. However, this process is so long that it will take billions and billions and billions of time, the current age of the universe for a black hole to completely disappear. This makes the death of a black hole insignificant in the grand scheme of things.
