white dwarf stars(The Last Light Before Eternal Darkness)

The universe is a vast place. No one knows where the universe began or where it ends, and even the Supreme Buddha preached that searching the universe was futile. However, our universe has composed of galaxies that are the size of sand on Earth. If a star of great mass, the hydrogen and helium reactions in it are over, the giant super-nova will explode, eventually turning the star into a black hole.

So if you count the number of stars in these galaxies, it will be too much for the person to count on in his all life.

 keep in mind that even these stars do not last forever, they are also impermanent.

star of great mass, the hydrogen and helium reactions in it are over, the giant super-nova will explode, eventually turning the star into a black hole. stars, that not enough mass to be a black hole turning in to neutron stars.

Then others?

white dwarfs

The vast majority of stars in the universe are white dwarf and red dwarf stars. According to scientists, there are many red dwarf stars in the universe. A white dwarf star is one of the most enduring things in the universe. A white dwarf star is a star that is not massive enough to be a black hole or a neutron star after its death.

How a star becomes a white dwarfs

Let’s try to illustrate this with our sun.

Our Sun is a medium-sized star. According to NASA’s official website, the sun is one of the smallest stars in the universe. One day all of our sun’s hydrogen will be depleted, and the sun will burn helium, producing very strong and heavy elements, which will then result in a massive expansion of the outer layer of our sun.

Our sun will be so large that the sun will expand to the orbit of Mars. Then our planet will be gone. However, eventually, the sun will expand and explode. But remember that it is not a supernova explosion but a very small explosion. However, the Sun has to be about 20 times larger than the Sun to make a Super Nova explosion to become a black hole, according to NASA’s official website.

All that is left is the central part of the sun that previously produced the hydrogen. It is a very small part of it, approximately a size smaller than the Earth. In the end, this surviving center could be called a white dwarf star. It is also known as star corpses. Because it is a small star, if it had a planet near it, the star would look like the moon in the night sky. Because the light of a white dwarf is so low.

The gravity of a white dwarf

And when a star becomes a white dwarf, it shows great gravity. If we ever get on a spacecraft, our plane will squeeze like a noodle. Speaking of mass, our weight can feel 4 or 5 times greater. You will not be able to go near that star and wear at least one suit. Because of the strong mass, you can die from the weight of your asthma. For example, a sandbag can make you feel tons of it.

Interesting facts about white dwarfs

Planets may also exist near a white dwarf. There may also be living organisms. Scientists have said that a number of Earth-like planets have been discovered, some of which are near super-white dwarfs. Also, seven stars have been found around a star called Trappist 1.

White dwarf stars are the hottest object in the universe. It is 40 to 50 times hotter than a normal star. But the temperature of these objects does not come out, because its temperature is located inside the outside, only the outside layer. So a white dwarf star is going to die a lot. However, the light of the white dwarf is also the last light in the universe.
