Gamma ray bursts are the most violent explosions born in the universe. Gamma ray bursts are as short as a thousandth of a second, or as long as a few hours, and will release huge energy in a short time. Compared with the sun, the energy it releases in a few minutes is equivalent to the sum of trillions of years of sunlight, and the energy it emits is usually hundreds of thousands of times that of typical sunlight.

Because the gamma ray burst is extremely bright, even if it is a long distance away and travels through a long time, it can still be seen by us. Scientists even observed gamma ray bursts that were produced by the first star explosions formed in the universe about 100 million light years away.

On December 14, 1997, astronomers observed a gamma-ray burst, which was 1.2 billion light-years away from the earth (this distance is far enough, so 8ooo light-years are considered very close). This time the gamma-ray energy released by the explosion in 5o seconds is equivalent to the total radiation energy of the entire Milky Way galaxy for 2o years. This gamma-ray burst lasts within one or two seconds, and its brightness is as bright as the entire universe except it. Even near it, the high temperature and dense situation of one thousandth of a second after the Big Bang was reproduced.

On January 1999, astronomers observed that the gamma ray burst emitted ten times the energy that was in 1997, and the gamma ray burst that exploded on April 1, 2o36 was three times stronger than that in 1999. This is also the most powerful gamma ray burst known to mankind to date.

Gamma ray bursts are born almost every day in the universe, and the direction is uncertain. If a planet with life is unfortunately on the release path of the gamma ray burst, then the life on this celestial body will suffer a catastrophe.

During the long universe, most of the alien lives that cannot be seen, escaped, and cannot defend against gamma ray raids have been swept to death.

According to model research, 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, the distance between stars was much closer than now, and any gamma ray burst would affect countless surrounding stellar systems. It can be imagined how disasters and tragic the universe civilization that was born at that time were extremely tragic.

If a gamma ray burst appears in the Milky Way, humans on Earth may face a big trouble. If the explosion distance is close enough, the gamma ray burst can instantly destroy life on Earth without warning.

Then, this brilliant cosmic fireworks show is time for the solar system and the earth to turn

This is a typical long gamma ray burst, which formed in the most violent death process in the universe - the Nova explosion. The entire gamma ray burst lasted for about 1 minute.

As predicted by the Interstellar Exploration Alliance crisis research team, this time the gamma-ray explosion is more like a sniper rifle than a shotgun. If it weren't too close to the ballistic, it would not be directly strangled.

However, the entire earth and the entire solar system are impartial and coincidentally located on the ballistic trajectory!

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

First, it was the core of the solar system. Within one second when the gamma ray burst arrived, the brightness of the sun's surface suddenly jumped to multiple levels, and continued to emit dazzling light within one minute of the explosion. In the dark universe, the sun suddenly began to flicker irregularly, and the brightness of the side facing the gamma ray burst was several levels higher than the back.

Star O4 is 125 times larger than the Sun. This gamma ray burst is like a big brother slapping the Sun brother hard when he was dying.

Of course, this slap, that is, a gamma ray burst, does not have the ability to pose a life threat to a star in its prime. The reaction during the attack of the sun was like the strong anger it expressed, and that's all.

It was not until four years later that the interstellar immigration camp located in the Alpha Centauri system saw the impact of the sun through a level telescope.

However, other planets in the solar system are not as tough as their elder brother.

Several planets with an atmosphere, within 1 second of the raid, no matter how thin the atmosphere is, they instantly burst into a strong and gorgeous color similar to the aurora.

If someone on Earth happens to look up at the sky at this moment and his eyes have high camera function, he will see an extremely short and magnificent scene that appears in the sky. Then, the brightness in the sky begins to rise sharply, and his eyes can be blinded in an instant. Then, the brightness of the sky will jump to a level again, which is the result of the destruction of the atmosphere on the front of the earth by a gamma ray burst.

Finally, the man who looked up at the sky was immediately killed on the spot and was turned into a pile of bones by the continuous arrival of gamma ray energy beam. The whole process did not even last for a second. This means that the power of this gamma ray burst has far exceeded the expected level.

Although the gorgeous cosmic fireworks performance lasted for only about one minute, the entire solar system had already turned into a purgatory.

As long as the second is like the year, the eight planets in the solar system, numerous satellites, and other asteroids have not escaped the destruction of powerful gamma-ray bursts.

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

Since gamma rays are electromagnetic waves with wavelengths shorter than o.o1 angstroms, they have extremely strong penetration power. Destroying the front atmosphere, countless high-energy gamma rays began to continuously bombard the surface of the earth and the ocean. Their terrifying penetration power penetrated directly down the ground without any pity and no leave.

All plants gradually turned into charred black, and the animals that lived comfortably on the surface were instantly killed, and then slowly turned into bones. Life in the ocean was also hard to escape misfortune. However, plants and animals were lucky than humans, because the process from birth to death was in a moment. Until the moment of death, they never knew the arrival of disasters in the end, so they never experienced spiritual torture.

After the gamma ray burst lasted for 10 seconds, even the ocean began to boil. A large amount of water vapor rose into the sky and was bombarded into the universe by subsequently arrived gamma rays. The scene could no longer be described in words.

The powerful radiation began to spread to the entire earth at an extremely high level, the ozone layer had completely disappeared, and the residual atmosphere was filled with harmful gases such as carbon monoxide.

On the other end of the earth's surface, it has completely become hell. Countless humans and animals began to wail in a sarcasm. Although the strong radiation and harsh environment did not immediately deprive their lives, the god of death had already waved his huge and sharp sickle and stood beside them, grinding his teeth and sucking blood.

Although, most elderly people are quietly waiting for death at home, or end their lives in advance in other more intense ways after saying goodbye to their loved ones.

However, many people who have a breath of surviving become more and more crazy driven by the instinct of survival. At the entrance of every underground city, residents from the surrounding area gathered, and they frantically beat the underground city to hold the closed entrance like thousands of years of ice.

However, until they patted their hands and exposed their bones and blood, they still received no feedback.

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