Gamma-ray bursts are the most violent explosions in the universe, and can be as short as thousandths of a second to several hours, releasing enormous amounts of energy in a short period of time. Pen? Interesting? Pavilion wWw. ｂiquge。 If it is compared to the sun, it releases as much energy in a few minutes as trillion years of sunlight combined, and the energy emitted by a single photon is often hundreds of thousands of times that of typical sunlight.

Because gamma-ray bursts are so bright, they can still be seen even from a long distance and over a long period of time. Scientists have even observed gamma-ray bursts about 13 billion light-years away when the first stars formed in the universe exploded and died.

On December 14, 1997, astronomers observed a gamma-ray burst at a distance of 12 billion light-years from Earth (a long enough distance to be considered 8,000 light-years away), which emitted gamma-ray energy in 50 seconds equivalent to the total radiation energy of the entire Milky Way in 200 years. This gamma-ray burst lasted for a second or two, and its brightness was as bright as the entire universe outside of it. In its vicinity, the high temperature and high density of one thousandth of a second after the Big Bang were reproduced.

On January 23, 1999, astronomers observed a gamma-ray burst emitting ten times more energy than in 1997, and a gamma-ray burst on April 1, 2036, is three times more powerful than the 1999 one, making it the most powerful gamma-ray burst known to date.

Gamma-ray bursts occur almost every day in the universe, and the direction is uncertain, if a planet with life is unfortunate enough to be in the path of a gamma-ray burst, then life on this celestial body will be wiped out.

In the long time of the universe, most of the alien life that could not be discovered, escaped, and could not defend against the sudden attack of gamma-ray bursts has been swept away.

According to the model, scientists have found that since the birth of the universe, gamma-ray bursts may have cleared more than 90% of the galaxy space, especially in the early days when the universe began to expand, and the distance between stars was much closer than now, and any gamma-ray burst would affect countless surrounding galaxies. It is conceivable how the cosmic civilization born at that time was so calamitous and miserable.

If a gamma-ray burst appears in the Milky Way, humans on Earth could be in big trouble. If the eruption is close enough, a gamma-ray burst can destroy life on Earth in an instant without warning.

Then, this time the dazzling cosmic fireworks show is the turn of the solar system and the earth.

......

This is a typical long gamma-ray burst, which forms from the most violent death process in the universe - a supernova explosion, and the entire gamma-ray burst lasts for about 1 minute.

As predicted by the Planet Exploration Alliance's crisis research team, this time the gamma burst is more like a sniper rifle than a shotgun. If it is not too close to the ballistic, it will not be directly strangled.

But the whole Earth, the whole solar system, impartial, very coincidentally, is located right on a ballistic trajectory!

When this long-planned gamma-ray burst reached the solar system thousands of light-years away, it immediately devastated the entire solar system like a tidal wave.

The first is the core of the solar system, where the brightness of the sun's surface suddenly jumps by several levels within one second of the gamma-ray burst arrives, and it continues to glow brightly for the entire minute of the outbreak. In the deep darkness of the universe, the sun suddenly began to twinkle irregularly, and the side facing the gamma-ray burst was several orders brighter than the backside.

The star WR104 is 125 times larger than the Sun, and this gamma-ray burst is like a big brother slapping the sun brother when he is dying.

Of course, this slap in the face that gamma-ray bursts are not capable of threatening the life of a star in the prime of life, and the Sun's reaction during the attack is like the intense anger it expresses, nothing more.

It wasn't until four years later that the interstellar immigrant camp in the Alpha Centauri system saw the Sun being impacted through a supertelescope.

However, the other planets in the solar system are not as tough as their big brothers.

Several planets with atmospheres, within 0.001 seconds of being raided, the atmospheres instantly burst into intense, brilliant colors similar to auroras, regardless of how thin they are.

If someone on Earth happens to be looking up at the sky at this moment, and his eyes have a high-speed camera function, he will see the magnificent scene that appears in the sky for a very short time, and then the brightness of the sky will begin to rise sharply, and his eyes can be blinded in an instant, and then the brightness of the sky will jump another level, which is the result of the destruction of the atmosphere in front of the Earth by gamma-ray bursts.

In the end, the person who looked up at the sky was instantly killed on the spot, and was reduced to a pile of bones by the continuously arriving beams of gamma energy. The whole process didn't even take more than a second. This means that the intensity of this gamma-ray burst has far exceeded the expected level.

Although the brilliant cosmic fireworks show only lasted about a minute, the entire solar system had already turned into a purgatory.

The eight planets of the solar system, numerous moons, and other asteroids have not escaped the ravages of powerful gamma-ray bursts.

On Earth, after billions of years of arduous journey, many lives that were born were ruthlessly harvested in less than a second.

Since gamma rays are electromagnetic waves with a wavelength shorter than 0.01 angstroms, they are extremely penetrating. Destroying the frontal atmosphere, countless high-energy gamma rays began to bombard the surface of the earth and the oceans continuously, and their terrifying penetrating power penetrated the ground without mercy and without leaving behind.

All the plants were gradually turned black, and the animals that lived comfortably on the surface were killed in an instant, and then slowly turned to bones, and the life in the ocean was also doomed. However, plants and animals are luckier than humans, because the process from birth to death is just a thought. Until the moment of death, they never knew that the apocalyptic calamity was coming, so they never experienced mental torment.

When the gamma-ray burst lasted for 10 seconds, even the ocean began to boil, and a large amount of water vapor rose into the sky, and was bombarded into space by the subsequent gamma rays, the scene can no longer be described in words.

Powerful radiation has begun to spread to the entire earth at an extremely high rate, the ozone layer has completely disappeared, and the remaining atmosphere is full of harmful gases such as carbon monoxide.

On the other side of the earth's surface, they had been completely reduced to hell, and countless humans and animals began to wail bitterly, and although the intense radiation and harsh environment did not immediately deprive them of their lives, the Grim Reaper had already wielded a huge and sharp scythe, standing beside them grinding their teeth and sucking blood.

Although, most of the elderly people wait quietly at home to die, or end their lives early in other, more drastic ways after saying goodbye to their loved ones.

However, many of the people who survived were driven by the instinct to survive to become more and more crazy, and at the entrance of each underground city, residents from the surrounding areas gathered, and they frantically slapped the entrance of the underground city that was as closed as ice for ten thousand years.

However, until they slapped their hands and revealed their bones and blood, they still did not get any feedback......

In less than five minutes, the whole world was in a dead calm.

ps: A book that I recommend to friends, it is also a wonderful original science fiction article, the title of the book is "Intelligent Mechanical Crisis: Advanced War", friends who like science fiction can go and see it! (To be continued.) )
