In the early summer of the universe, when the flowers of the stars bloom, the bright blue petals are the shortest-lived ones. Compared with the small mass stars that shine in the long night of the universe, the life of a large mass star is like a flash in the pan, short and brilliant.

In the youth of massive stars, the energy of nuclear fusion resisted the collapse of the star's shell, like a leather ball, the gas tried to inflate the ball, and the tension of the outer skin tried to make the balloon contract, and the balance between the two could make the star's large celestial sphere stable.

So in the long night of the universe, the black curtain was inlaid with a brilliant sea blue gemstone.

The blue giant star looks like a blue ocean from afar, but its waters are not warm salt water that nurtures life, but deadly blue nuclear flames.

The deadly waters are 600 billion meters deep – equivalent to 60 million Mariana Trenches, which translates to about 2,000 light-seconds in astronomical units.

If you travel to the inner core of the blue giant, you can only end up being instantly squashed, and the atoms that make up your body will be burned into plasma and burned out by the fusion flames.

The nuclear flame resembles a giant dragon, blue light occurs in the dragon's mouth, roaring furiously, and the dragon's breath spews high-energy particle rays into space, forming a stellar wind that is thousands of times stronger than the sun, and contains enough energy to break all the genetic chains in all cells of life.

The sun burns 4 million tons of matter in one second, and one of two billionths of this energy shines on the earth to give birth to a civilization, and the energy radiating to the earth's surface is about 17 trillion kilowatts per second, which is equivalent to 35,000 times the total annual energy consumption of the world.

But for every time the mass of a star doubles, it burns ten times faster............ Blue giants with nearly 100 times the mass of the Sun tend to output millions of times the energy of the Sun!!

Such a huge amount of energy is hard for the poor brain of a human being to imagine, and the boundless expanse of energy has set off waves and waves on the surface of the blue giant.

The surface area of the Earth is 510 million square kilometers, the surface area of the Sun is 1.7 million times that of the Earth, and the surface area of blue giant stars is often millions or even tens of millions of times that of the Sun.

Such a large and vast amount of energy has set off huge waves on the surface of the ocean a trillion times the vast Pacific Ocean, and even the gravity of the star can hardly restrain this energy, and sometimes the entire mass of Jupiter will be ripped from the star......

However, the product of the fusion reaction is helium-4, and as the age of the star increases, its core produces more and more helium-4, which in turn has a greater specific gravity than hydrogen, and likes to sink to the bottom, that is, in the center of the core, and gradually, the area of the hydrogen reaction moves outward like wildfire.

The helium in the center is getting tighter and tighter, but the surrounding hydrogen is still fused. The scene is very much like a scorching stone baking a bread ball wrapped in them.

Finally, the helium in the core was ignited, and these heliums were like gasoline that had been thrown into the fire, and they burst into flames in an instant.

So the star emits a bright light, which is called a helium flash.

But helium fusion produces far less energy than hydrogen fusion, so it's just a futile struggle for the star, who later gets weaker.

The combustion of helium nuclei does not release as much energy as hydrogen, so this period is relatively short-lived. The carbon and oxygen produced by helium fusion then form a new core, which would mean the death of the star if it appeared on a celestial body like the Sun.

But the hundred-legged insect of the blue giant star died but did not stiffen, and under the terrifying temperature and tremendous pressure, the fusion advanced again and began to fuse the elements into neon, and then neon into heavier elements.

Fusion is like eating sugar cane - one section is not as sweet as the other, and as fusion progresses, less and less energy is produced, and the time for each element to hang is getting shorter and shorter.

Until the production of iron, iron does not produce energy when it is fused, but consumes energy!

As a result, the gravitational pull that once gave birth to the star also kills the star, and the core is the first to collapse. But the pressure of deterrence tries to stop the rise of the Dark Star.

Particles are usually exclusive, and they cannot occupy the same position in space. It's like a group of naughty children, if you want them to lean together, they will always push and push, and the closer they get together, the greater the force they will use, and this kind of mutual repulsion between particles is called degeneracy pressure

The electron degeneracy pressure first tries to stop the core from collapsing, and if successful, the core will collapse into a white dwarf, a teaspoon of white dwarf material weighing hundreds of tons.

But the atoms were so weak that gravity crushed them mercilessly.

Then there is neutron degeneracy pressure, which, if successful, will collapse the core into a mere neutron star, and a teaspoon of neutron star matter weighs in billions.

But the neutron is also too weak, and gravity crushes the neutron mercilessly.

Finally, there is the quark degeneracy pressure, which, if successful, will become a theoretically existing quark star, denser than a neutron star.

But the quark was still too weak, and gravity crushed the quark mercilessly.

If a white dwarf is a dense nucleus, a neutron star can be seen as a huge nucleus (neutron cluster), and a quark star is a giant neutron.

But at this point, there is no longer anything that can stop the birth of a black hole, a dark star. So a black hole was born in the heart of a star.

Time and space lose all notion here. It will devour all things with its supreme gravitational density.

Born in the center of a star, the newborn dark star craves delicious flesh. The shell that has lost its support collapses and violently hits the volumeless singularity, the black hole rotates at high speed, and the shalt material that is sucked in will form a disk, ejecting a powerful jet, and the two poles of the dead star each appear as a giant column of rays when the black hole devours the star, which is as wide as the Earth, and it breaks through the star, which is called a very supernova explosion.

The nuclear reaction was ignited for the last time, the war of fire and gravity for thousands of years was over, a gamma-ray burst had descended, life would be swept away in a few hundred light-light years, and the star had become a ray of light, enough for the entire galaxy to witness his death!

In its original place, only a black hole several times the mass of the Sun remains.

In another case, the black hole that forms inside the star rotates only slowly, and although the star also emits a weak jet, almost all of the stellar material is sucked into the black hole. This burst is called a faint supernova.

The dark star thus formed is extremely terrifying, possessing almost all the mass of the parent body, and its strength is more than ten times that of ordinary dark stars, and it is very likely that the hammerstone is such an existence.

[Human, have you ever seen a hundred billion stars, lit up by the same dawn?] We've seen it. And then we'll just ...... Extinguished. ]
