What is a black hole?
There are many infinite mysteries in this infinite universe. Humans have so far been involved in many of these mysteries
Unseen, the most dangerous is the black hole, also known as the black hole. How dangerous this is
That is, it can easily incorporate any large planet. Return again if any black hole occurs
Will not be. He will not leave anything that has come into his path.
The black hole has so much power that it can even rotate light traveling at a speed of 3 lakh kilometers per second.
The reason a star glows brightly and releases energy is because of the hydrogen in that star. These are hydrogen atoms
Becoming helium releases excess energy and radiation. On the one hand from the energy core released like this
That is, the gravitational force on the other side of the star as it exits the center
The star emphasizes the middle part.
In this way a star is stable because the forces act against each other at the same time. A few crores
A star that has been burning like this for years will run out of hydrogen after a while. Whenever in the star
When hydrogen is depleted then no energy is released as the nuclear reaction does not take place.
SuperNova Explosion
Thus the star that is so large due to the gravitational force on the core is itself the same small balls
Changes .so the density of the star increases and the pressure increases exponentially.
Explodes. This is called the SuperNova Explosion. If the star of the explosion is small it is
Turns into a Neutron Star. This Neutron Star has tremendous density.
If the exploding star is large, it will turn into a black hole after the star explodes. To this black hole
Has the highest gravitational force in the universe. These dead stars turn into black holes.
But not all dead stars become black holes.
What is stellar black holes
For any star to become a black hole, it must be at least 20 times larger than the Sun. But
The sun has no chance of becoming a black hole.
Called stellar black holes. These Stellar black holes are very small. But also very dangerous.
These number in the millions across the galaxy.
What is supermassive black holes
These supermassive black holes form when a star a few million times larger than the Sun dies. These supermassive black holes are located in the center of the galaxy. The name of the black hole in this Milky Way that we are in
Segatarious-A-Star Its size is quite large. This means that its diameter is 4,40,00,000 km.
It is 25,640 light years away from Earth. (1 light year = 94,60,00,00,00,000) from this block hole
There is no danger because it is so far away from the earth.
