Black hole

One of the biggest puzzles in outer space and the most destructive objects in the universe .. What do you think that could swallow the sun, which represents the center of our solar system and the earth at this moment is only a grain of sand swallowed by the black hole with the sun

Black is a region in space that contains a large mass in a small size called the critical size of this mass

The black hole is formed after the life of the stars, when it explodes, and it passes, in turn, eventually turning into a black hole

But what determines the fate of the star after its explosion is what is called the "Chandrasekhar limit". This limit is the amount of mass (1.4 solar masses) that if the star does not exceed it will turn into a white dwarf, and if it exceeds it turns into either a neutron star or a black hole

The sun is impossible to turn into a black hole because of its small size, it will turn into a white dwarf

The black hole absorbs the light passing by it by the action of gravity, and it appears to those who observe it from the outside as if it is an area of ​​nothingness since no signal, wave, or particle can escape from its influence until the light is faster in existence to escape from it, so it appears black

To turn the globe into a black hole, this necessitates its transformation into a ball with a radius of 0.9 cm and the mass of the same mass of the present earth, meaning the compression of its material to make it without interstitial voids in its atoms and between the particles of the nuclei of its atoms, which makes it small like a table ball in size and its huge weight remains the same


If you see that I really deserve support from here
