Chapter 1: Gamma-ray bursts
Leaving aside the purely theoretical conjecture of the Big Bang, the most terrifying ultra-high-energy Big Bang ever observed in the universe is undoubtedly a gamma-ray burst.
This is the most violent Big Bang in the universe, it is real, and it occurs intensively in the vast cosmic space, constantly threatening the existence of life.
Just because the gamma rays it emits are enough to kill all life in its path, the huge amount of energy released in a short period of time is comparable to the energy released by hundreds of suns in a lifetime.
Even if it emits a single photon, the energy is often hundreds of thousands of times that of sunlight.
This energy, which was born from the brief explosion of a huge star when it ran out of fuel, is the enemy of life and the strongest killer in the universe.
Gamma-ray bursts occur almost every day in the universe and in random directions, and if a planet with life is unfortunate enough to be in the path of a gamma-ray burst, then life on that celestial body will be wiped out. Because it happens so frequently, about 1 in 10 million objects are swept by gamma-ray bursts.
Earth, once a member of the 'Gamma Ray Burst Victim List', suffered a mass extinction, but it stubbornly survived, and in the long desolation, life and civilization were born again.
On April 1, 2017, the lovely earth will usher in the second visit of the 'Grim Reaper'.
A very dense neutron star from billions of light-years away hits another neutron star, and a terrifying burst of gamma-rays is released like never before.
The explosion only emitted for forty-two seconds, but the energy evaporated many stars in its path, rushed all the way out of the river system, and traveled through the dark interstellar space for billions of years.
Like a randomly fired 'Grim Reaper stray bullet', no one wants to be 'shot'.
Of course, life hopes that this unprecedented gamma-ray burst will always exhaust its last energy in interstellar space, and never enter the next river system.
However, contrary to expectations, there was a spiral galaxy that happened to be on the trajectory of the 'stray bomb', and the super energy burrowed into this river system with a diameter of more than 100,000 light-years.
It is the unlucky galaxy, which has ushered in a second lottery after the baptism of baptism 500 million years ago.
Of course, compared with the vastness of the universe, the propagation path of gamma-ray bursts is not very wide, if possible, gamma-ray bursts can completely sweep away some galaxies, and finally enter the galactic black hole to be swallowed, which is the best result, and it is also a common result. After all, on the scale of the Milky Way, this level of energy is nothing, and the galactic black hole can be swallowed up and devoured in its entirety.
The only thing that really kills this is life.
Unfortunately, a galaxy that gave birth to a planet of life happened to be in its path, and the civilization on it became the 'first prize' winner.
And because the gamma-ray burst hits the speed of light, the civilization on the planet of life will not realize that it has won the lottery until it is destroyed.
The 'lucky one' is the earth.
A super gamma-ray burst cut in from a unique angle, and before it could evaporate the sun, it crashed into the Earth first.
This one is no more powerful than the one 500 million years ago, and although it consumes too much energy in the process of propagation, it is enough to make the earth no longer able to support life, and it will be in an extreme environment until the end of its life.
Lore, life on Earth will not react in any way, and the moment it goes through all this, it will end in an instant.
However, nature played a big joke in this second, and the universe itself is an infinite coincidence, with countless unknowns and miracles.
The terrifying gamma-ray burst disappeared the moment it reached the earth's surface and crashed into the atmosphere.
Not to mention life on the surface, even the atmosphere itself has not been damaged much, and the energy that is so big that the sun can only tremble is directly gone, as if there is an invisible space that swallows it all at this moment.
......
The first to detect this gamma-ray burst was the Spitzer Space Observatory.
It was in a deep-space orbit at the second Lagrange point, on the other side of the Earth at the time of the gamma burst, but it was not attacked until an hour later that it detected the residual anomalous visible light and radiation background in space.
A large amount of observation data was transmitted to the ground, which directly caused the panic of NASA, the US space agency.
"Gamma-ray bursts, visible light found in orbit around the planet Earth, so close?"
"Not only that, but the energy level is very high! According to the residues, the propagation time has exceeded that of the 1999 observation by about ten times!"
"What! God, are we alive?"
In 1999, a distant super gamma-ray burst was observed on Earth, with an emergy equivalent to the total amount of energy released in the entire Milky Way galaxy over a period of 2,000 years.
It was already the largest gamma-ray burst ever observed, and now they have seen a bigger one, breaking the record.
The energy index is comparable to the total energy release of the entire galaxy in 20,000 years!
The terrifying astronomical figures, of course, are the pinnacle of the location of the radiation site, after billions of years of transmission and attenuation, when they reach the earth, it is no longer enough to destroy the earth's molecular structure, but radiation alone is enough to destroy the earth's ecological environment and turn it into hell.
At this moment, the society on the earth is still running smoothly as if nothing has happened. Even during this time, there were no space station docking missions, and there were no casualties in the various space station laboratories. Otherwise, when the gamma-ray burst comes, as long as there are people in the Tiangong-2 and other space stations in low-earth orbit, they will bear the brunt of the attack, and they will never be spared.
This bizarre phenomenon has confused the staff of various space agencies.
The staff of the various national observatories who observed the remnants of 'Afterglow' were all frightened, and all of them turned pale and muttered to themselves in fear.
"Why aren't we dead yet?"
Several of the Chinese and European aerospace engineers could not stand still, leaning softly against the nearest place, their lips trembling.
This is so lucky, so lucky that it is unscientific and unreasonable!
It can only be explained by coincidence, an unknown coincidence, perhaps the extreme complexity of the underworld, and the survival of the earth.
The bizarre survival of the Earth alone is enough for all human aerospace experts to study for the next few decades, if not hundreds of years.
Within a few hours of the incident, a joint research team was set up in the global space field, and experts and engineers from China, Europe and the United States shared data with each other to study and verify the 'doubts about the fact that the earth was spared'.
The first step in their research was to deny the fact that gamma-ray bursts had visited the Earth, and once there was a scientific basis to deny this, it would be reasonable for the Earth to be spared if the afterglow of space was nothing more than an astronomical illusion.
However, the iron-like data suggests that all this cannot be any optical artifact, because too much material in outer space has been subjected to severe gamma ray impact, and many space observation satellites that have been impacted have been scrapped.
"Is the Earth really in its path?
"No...... No, it's just hitting the earth...... The direction of the source is biased towards the North Pole, and there is no passage by the Sun or Jupiter in its path. Look, this is a visible map of the afterglow of a gamma burst, and it's all too obvious that if you tilt into the ecliptic plane, you hit the Earth!
"It's unbelievable that a gamma-ray burst has passed through the Earth and we're still unscathed?"
"No, no, no...... Nor is it traversing!you see! The path of propagation until the Earth comes to an abrupt end, and there is no radiation left on the other side, which means that the gamma-ray burst is ...... when it reaches the Earth. Gone!"
"Gone...... What does that mean? absorbed by the Earth, or refracted by the atmosphere?"
Do you know how much energy it takes to destroy the earth? In equivalents, it only takes seventy tons of TNT!"
It is 10,000 jing, and the power of 10 to the twentieth power is a huge quantity unit.
But so many tons of TNT explosive equivalents are nothing for the total energy value of gamma-ray bursts.
The physicist said: "The energy released by the sun in a day is equivalent to 80 tons of TNT, which is enough to blow up the earth once! If it is doubled tenfold on this basis, the energy is enough to bomb the earth to dust and fly all the debris out of the solar system." ”
"You can imagine what the total energy of the sun is for 10 billion years. ”
Another physicist said, "I've done the math, it's about 1.8 times ten to the power of forty-eight joules." Enough to destroy the earth...... To the twenty-fifth power of ten...... Return. ”
"Yes, and that's nothing more than the energy released by a gamma-ray burst for 0.0002 seconds. Now, do you think the earth is qualified to absorb this energy? And refraction...... Even if there is a coincidence in our atmosphere that we can't understand, miraculously refracting that energy, where does it go?"
"We only observed the afterglow of a gamma-ray burst...... But there is no sign of its departure...... Is it all ......"
"God's protection?"
After that, everyone fell silent.
With their knowledge, they are helpless against this mystery, and they feel very ignorant.
Although they are extremely happy to be alive, as scientists, they are extremely sad to find that there is no reasonable explanation for the luck of human beings.
The result of the first meeting of the joint research team was only the name of the gamma-ray burst 'Gentle Grim Reaper'.
The day is April 1st, and in the city, it may be April Fool's Day. But in the aerospace field of various countries, high-end scholars will not regard it as April Fool's Day, but as a lucky day for mankind.
For the time being, countries have not planned to make this incident public, but it is not long before many private organizations in society will observe the afterglow of the 'Grim Reaper'.
Experts and scholars who have countless doubts about this have no idea that at the moment when the 'gentle death' descends and disappears.
In a small, fourth-tier inland city in China, a young man fell to the ground, unconscious.
He was just a passer-by on the street, walking on his front feet in high spirits, and the next second he felt like he had been knocked unconscious by something.
Although it didn't seem to have any external injuries, there were still well-meaning bystanders who came forward to check on them.
After discovering that he really fainted, he hurriedly called 120 and sent him to the hospital for emergency treatment.
The whole process is just a trivial thing in the city, not even news.
No one thinks this will have any far-reaching impact.
