Deep in the universe.

The Milky Way, a medium-sized barred spiral galaxy, has 400 billion stars, and its mass is equivalent to 210 billion suns.

In a remote corner of the Milky Way, a very inconspicuous mini-galaxy – the Solar System.

At this time, in the inner circle of the solar system, Jiayu stood on a meteorite that was only one hundredth the size of the moon, like dust in the dust.

Dressed in a diamond-cut battle armor, Jiayu stared blankly at the almost eternal universe, and in the depths of the universe, there seemed to be earth-shattering changes brewing.

In the dark space, in addition to the two stars that can be seen by earthlings, one large and one small, in the dark sky, Jiayu saw a new star!

It was an unfamiliar red star, and after a few seconds, it began to shine brightly!

It's not that some strange star has broken into the solar system, but that there is a huge star that has entered the last glorious time of unknown light years away!

Jiayu's mind was already full of absolute shock, so shocked that he couldn't think, and the power of his breath was suppressed. All of his aura has been occupied by a cosmic vision!

"This, what's going on?"

This is a red star, and in the few seconds when Jiayu looks up, this star, which is difficult to distinguish with the naked eye, becomes the brightest star in this universe.

The Hadron Facility System confirmed the names of the newborn stars, their parameters, preliminary observations, and various data retrieved from the database after one ten-thousandth of a second.

The invisible light holographic display surrounds Jiayu, bursting out with a huge amount of text information and sounding an alarm.

"Betelgeuse, the α star of Orion!"

Jiayu looked at the subtitles, a little incredulous, "Betelgeuse? Orion α star? Isn't it the superred giant closest to the Sun? Why is it erupting at this point? ”

…………

There is no atmospheric scattering in space, and the brightness of red supergiants jumps to the magnitude of ordinary stars and gradually stabilizes.

Jiayu read the introduction of the hadron equipment system while observing the nova that appeared in the universe.

Through the hadron equipment system, Jiayu has a preliminary impression of this familiar and unfamiliar star.

Orion α star, the ancient Chinese people called it Betelgeuse after observing the sky at night.

Betelgeuse is one of the Chinese astronomical theories "Three Walls and Twenty-eight Houses", and belongs to one of the Seven Houses of the Western White Tiger.

Betelgeuse, in fact, is a part of the 88 constellations in the West, Orion. Betelgeuse is a very famous red star.

About 640 light-years from Earth, it is almost the doorstep of the solar system.

Betelgeuse is much larger than the main star of the solar system, the Sun, and its volume is not fixed, and through astronomical telescopes, Betelgeuse will be larger in a few years and smaller in a few years.

The star, which is about to explode as a supernova, is like a cosmic beast, breathing slowly and spending the last years of its life.

In the course of the annual cycle, Betelgeuse has an average volume of about 1,120 to 1,200 times that of the Sun!

Inside this red supergiant, it can fit the nine planets of the entire solar system! The Sun is only 1.6 billion in size in this superred giant!

Although Betelgeuse is large, the mass of the star is very pitiful, only 23 times the weight of the sun, it is a super large gas balloon, but the temperature on the surface of this ball is too high. Moreover, it is in a state where it can erupt at any time.

What can destroy the universe - a supernova explosion!

More than 640 years ago, when it was still the early years of the Ming Dynasty, the ninth year of Zhu Yuanzhang's reign of Hongwu, 640 light-years away, the supernova of Orion exploded, and the first beam of light rushed towards the solar system from that year.

…………

Jiayu waved her hands wildly, too excited to control herself. At this time, he realized that he was still wearing the diamond-cut battle armor, which was not a homemade Xuanwu power armor.

He cursed secretly, "Is my brain frozen?" What a missed opportunity, I'm a human sinner! What a once-in-a-lifetime opportunity! ”

All kinds of detection equipment and data acquisition equipment are installed in the basalt power armor built by Jiayu himself, and the supernova explosion, except for the recent binary neutron star merger, gravitational wave data and optical data observed by scientists around the world, human beings are rarely able to collect all the information data of any supernova explosion.

This is the first time.

Jiayu quickly analyzed, "The Earth's satellite constellation, the Watchman Satellite System, should have started on its own and made a comprehensive record, and my current command signal can't be sent at all, so I can only hope that the satellite will give power; The hadron equipment system also records first-hand information, which can be shared in the database of the Xuanwu No. 1 battle armor if there is a chance. ”

Fat Bai flashed out with a snap and nodded vigorously, indicating that the hadron equipment system had already recorded the whole process.

At this time, Jiayu breathed a sigh of relief.

But as the hadron equipment system provided more and more information, Jiayu finally discovered the anomaly.

His face changed, "What? Destroy the world? Gamma ray burst? This is funny, the house leak happened to rain overnight, and the earth is too unlucky. ”

Hadron equipment system, which sends out the highest level of early warning information.

The light arriving more than 640 light-years away is about to destroy this dusty galaxy.

…………

After the star explodes, in addition to the light of the explosion, the energy of the high-energy rays is huge, and the material produced by the supernova explosion will pass through the barren land of the solar system after hundreds of millions of years.

Scientists on Earth have long calculated that Betelgeuse's axis of rotation, which does not point to the solar system, has an error of 20 degrees.

The axis of rotation is like the muzzle of a super sniper rifle, the axis, where it is pointed, the high-energy rays, will be compressed into the strongest laser in the universe, cut to wherever it goes!

Hadron equipment system observations show that after the Big Bang of Betelgeuse supernova, the axis of rotation of the star has changed!

Under the influence of some unknown force, the supernova exploded for a few minutes, and the axis of rotation of the star was tilted in the direction of the solar system, about half a degree!

If calculated at this rate, the gamma-ray explosion produced after Betelgeuse's explosion will be very accurate, splitting the solar system in half!

Like a big knife from 640 light years away, it can easily split a small galaxy!

The earth has entered the end times, but God still doesn't let it go, and he has to make up for it......

Jiayu had a strange sense of calm, completely without the horror of the imminent destruction of the solar system, he just said to himself easily, "This knife is long enough, 640 light-years broadsword!" ”

The scale of such a galaxy apocalypse is so huge that no one has a temper and can only accept their fate.

Now it is completely impossible to build a spaceship and escape from the solar system, and the creatures of the entire earth can only wait for death.

The gamma-ray blast emitted from 640 light-years is a flame of destruction that obscures the sky and the sun, and is known as the "destroyer of all worlds" of the living planet!

Gamma rays are the highest energy of electromagnetic waves.

And gamma-ray bursts are equivalent to gathering the energy of all stars within a range of 100 million light years and releasing them in the form of "laser beams". A gamma-ray explosion of medium energy in one second is equivalent to the energy emitted by the sun over a lifetime of 10 billion years.

The speed of light, after all, is the upper limit of this cosmic speed.

Gamma rays hit the earth, and all life on the earth will die in an instant!

The ozone layer is gone, the sea water is evaporated in a matter of minutes, the land is barren, and the sand dunes are everywhere.

In ancient times, the gamma ray explosion of a star caused the Ordovician mass extinction of the earth, and 85% of life in the ocean disappeared overnight.

…………

The explosion of red superstars is a feast for the eyes and science of an astronomy enthusiast plus a science and engineering man.

What is trapped on an alien planet, what is floating in the universe, these bad news, the Ministry was thrown away by Jiayu to the clouds, he has no time to build a stable thermal insulation warehouse, he can't take care of any Kunlun, he can't take care of the mining ship, turned on the whole channel visual acceptance, and then, Jiayu began to "storm clothes"!

The diamond-faceted armor faded like water, the basaltized carbon nanotube power armor was being generated, and Jiayu was completely naked, exposed to a vacuum close to absolute zero.

"Huh? A little cold? It's over, it's over, my little brother is going to freeze away......"

The fanatical Jiayu "woke up" and shook for a moment.

Standing shirtless and naked in the cosmic space near absolute zero, Jiayu suddenly felt that it seemed to be ...... It's not very cold.

He had a very strange premonition, and he stopped the dressing procedure of the Xuanwu Power Armor.

At this time, the "gamma-ray light knife" of Betelgeuse's supernova explosion has not yet arrived, and it may be a few days or hundreds of years before a high-energy gamma-ray burst of one to two seconds crosses the galaxy.

It may still be a long time before the destruction of the entire solar system.

At least, gamma-ray bursts that can actually "slice through" the Earth and the Sun are still on the way. The Earth is "vaporized" by the strongest energy in the universe, most likely in a few hundred years, or even thousands of years.

Jiayu muttered like a dream, "After a while, put on the armor and fully measure the rate of change of Betelgeuse's axis of rotation to see how long the solar system remains." ”

In four years, the earth will be destroyed.

After his death, who cares about the flood of the solar system?

…………

Gamma rays, which are the highest level of electromagnetic wave energy, "Light Man" Jiayu, are now limited to the evolutionary level of the underground, and cannot be seen yet, and can only look for traces of the Blade of Destruction through the trajectory formed by the rays and the cosmic gas nebula matter.

Jiayu didn't think about any epic questions about the future of the solar system at this time, he just wanted to fully record the astronomical wonders that would only appear in hundreds of millions of years.

He began to prepare to restart the dress routine for the Xuanwu Power Armor.

At this time, he suddenly froze!

He rubbed his eyes vigorously and shouted in his heart, "I, what did I see?" I'll go! ”

Indeed, he "saw" it!

At this moment, under the glow of the supernova Big Bang, Jiayu captured the almost infinite light of the universe.

At this very moment, the cosmic clock stands still, and time stops!
