Our universe is full of surprises, maybe that's why JBS Belden said "The universe is not as mysterious as you think, but it is more mysterious than you can imagine." Consciousness is staring in wonder at the starry sky above him. Its vastness plays an important role in making our universe mysterious. If the universe were not vast and had no different scenes, we would probably get used to it soon. If the wonders of the universe are mentioned, then black holes appear at the forefront. Research has shown that when a star has reached its physical age, the hydrogen in its core has produced iron through a nuclear fusion reaction, which is the death knell for it. After which the star explodes with a powerful explosion. Meanwhile, the light/energy emitted by this star is equal to billions of stars.
Super this process Nova (Supernova) is called. There are two types of forces in a star. One force is the pressure of the gases, which tries to expand the star due to the nuclear reactions at the core. While the second force is gravity which is pulling the star inwards. For billions of years, these two forces compete with each other, but after a supernova, the gas pressure force disappears and only the star's gravity remains, causing the star to begin pulling its material inward. Is. Due to this process, the density of the star begins to increase and eventually the star becomes infinitely dirty.
The center I collect Time and space become singularitycreates a severe bend in the sheet, due to which The star takes the form of a black hole.
There is a common misconception that black holes are so intense Gravitation is the pulling of any object from a distance However, this is not the case, but rather when a star black hole takes the form of , then its gravity is the same as when it
There was a star. The only difference would be that now there will be a circle around it ,It is called the Event Horizon
A black hole doesn't leave an object that comes in, even if it does
Why is there no light? Objects outside this point are called black holes
The stars are pulled by gravity. Black at this point
Time stops due to the extreme gravity of the pool. Because experiences
They also point out that gravity affects time, so it's accurate
You may spend a few months on the Event Horizon while on Earth
On arrival, you meet some old people and you are surprised
Stay when you realize that the old people in front of you are actually your grandchildren and great-grandchildren, while you yourself will be young at the time. This will be because the few months you spend on the event horizon are equivalent to decades to Earthlings. You can better understand this phenomenon by watching the science fiction movie "Interstellar". You can also think of an event horizon as a waterfall. Water is a medium for fish, so fish are not out of water can do
can come If a fish swims with the water of a waterfall
If it tumbles down with it, enough to get it back to the height
The speed must be such that it can resist the gravity of the earth. Absolutely
Similarly, the event horizon is the cosmic waterfall. Everything in the universe
Floating on the sheet of time and space. An item from Event Horizon
When a black hole falls in, it interacts with the entire universe
goes The speed of light to make it back into the cosmic ocean
Needs to be faster than that.
Black holes are beasts that defy our scientific laws
Appears to be scattered. This is why upon reaching the event horizon
Our scientific laws become helpless.
There are three types of black holes.
To the first type of black holes
They are called miniature black holes, because they are black holes the size of atoms
There are bowls. Scientists estimate that shortly after the Big Bang
Our universe
I had these tiny black holes, rather amazing
The thing is that we have made these black holes in the laboratory as well. Here
It is extremely important that the black balls are as small as possible
They go away (i.e. evaporate). That's why it's small
Black holes formed in the laboratory for billionths of a second and
Ended. After these small black holes came the turn of the stellar black hole
Is. These medium-sized black holes would have been thirty times larger than our Sun
Yes, there could be millions of such black balls in a galaxy
There are, because black holes form after stars larger than the Sun are destroyed
They change in the same way. After them the third type of black
Bolls are called Supermassive Black Bolls. This is ours
The most dangerous beasts of the universe from their birth to now
They have become extremely large by devouring everything around them
The most massive black hole in the universe at the moment is from our sun
billion times larger, which is contained in a quasar called TON618. every
Such a black hole exists in the center of the galaxy. Our galaxy
At its center is a supermassive black hole called Sagittarius A,
its 4 million times bigger than earth's son.
How amazing that in 1783, when John Mathilde
A black hole is predicted by the equations of then black hole
We did not have any signs and evidence. This is an imaginary object
was For this reason, black holes have been a source of curiosity for humans for hundreds of years. But in April 2019, for the first time, scientists were able to image a giant black hole at the center of a galaxy called 87 Massier. To image this black hole, 720 million times larger than the Sun, 8 large radio telescopes on different sides of the Earth were pointed at the black hole for 11 days, collecting 5.2 million gigabytes of data, which 200 scientists Interferometry by day and night for 2 years
Combined by technique and the first black hole in human history
Succeeded in making a picture.
| Our universe is an ocean of abundance, from every corner of it Facts come in front of us, which makes us wonder. As we descend into the ocean of the universe with the intention of exploring, so does our thirst increase. Currently, black balls are the inhabitants of the universe that continue to defy our scientific principles, but scientists are hopeful that we will soon discover scientific principles by which we can control them.
