The main source of energy on Earth is the Sun. We get light and heat because of the sun. Scientists have confirmed that the Sun is mostly hydrogen. About 73 percent. The remaining 25% is helium and 2% other elements. Nuclear fusion reactions are constantly taking place in the center of this star. As a result of this reaction, hydrogen becomes helium. And at this time, great power comes out.

The black hole-mystery

Hydrogen, the Sun's main fuel, is already half depleted. But the rest of the hydrogen that is in the chest of the sun, can continue for another 5 billion years. So, you have nothing to worry about. But the question comes, then what will happen to the sun?

In fact, due to the fusion reaction going on inside the sun, pressure is created on the outside. Again a force acts towards the center due to Sun's gravity. As a result, its contents cannot be spilled out, and it does not collapse and collapse on itself. remains stable. That is why the sun is round.

But when the hydrogen inside the Sun runs out, the Sun's gravitational pressure will increase compared to the pressure on the outside. The Sun will continue to contract. As a result the temperature will increase. In this situation helium will become carbon through fusion reaction. Then the size of the sun will increase again. Souradhipati will become a much, much bigger goal. Then he was in agony of death. In this condition Sun will eclipse Mercury and Venus. Even the Earth can fall into the Sun's orbit. In this way, the sun will gradually turn into a red giant or red monster star.

In this condition, the temperature of the sun will decrease slightly. After that, the remaining helium inside the Sun will gradually run out. Then the sun will continue to shrink again under the pull of gravity. At some point, the Sun's outer covering will no longer be able to hold. The outer part will be spread around as gas and dust particles. And the sun will turn into a small white dwarf or white dwarf. During this time the sun will be in an incredibly dense state. Then the size of the sun will be almost equal to the earth. How much will the size of the sun decrease? You will understand if you say the current size. Currently, the Sun is about 1.3 million times larger than the Earth.

Can the Sun turn from a white dwarf to a black hole? The simple answer is no. The Sun does not have the resources to turn into a black hole. Xavier Calmet, a physicist and black hole specialist at the University of Sussex in the UK. He said, 'The answer to this question is very simple. The sun is not heavy enough to turn into a black hole.'

Whether or not a star becomes a black hole depends on several conditions. Like star formation, rotation, mass etc. The minimum mass required for a star to become a black hole is 3 to 10 times that of our Sun. Stars that are born with so much mass can eventually become black holes. However, some massive stars do not become black holes. Explodes as a supernova. Or these stars become neutron stars. Or become a white dwarf star and spend the rest of its life as a vegetarian.

That is, our Sun does not have enough mass to become a black hole. A black hole is far away, the sun cannot even become a neutron star. This ruler of our solar system will spend the rest of its life as a silent white dwarf.
