Yu Ze quietly returned to the balcony of the apartment.

He opened the heavy envelope, which contained an Android phone and an unsightly USB flash drive.

Yu Ze checked the Android phone first, there was no SIM card in it, and the boot also showed that it was a new mobile phone that had not been registered.

This mobile phone is obviously not used for communication, and after the mobile phone is turned on, Yu Ze inserted the USB flash drive into the mobile phone, prompting that you need to enter a password to read the USB disk.

"Password?"

Bubishi didn't tell him that he still had a password.

Yu Ze was speechless, did Bu Bishi forget?

He suddenly had an idea, and thought about entering a string of passwords, which was his Alipay payment password, a long combination of English and numbers, which had not changed for many years.

That's right!

Compared with flash letters and bank card passwords, this password is the longest and most complex password that Yu Ze remembers in his mind, and it is also the password that impresses him the most.

And after correctly relying on this string of passwords to unlock the USB flash drive, Yu Ze sighed, which seems to further prove the origin of this USB flash drive.

After operating the mobile phone to open the U disk, there was only one PDF document in it, and Yu Ze slid his finger to click to open it.

The PDF document opened instantly, revealing a dense mix of text and pictures in Chinese and English.

"It's ...... Thesis? ”

Yu Ze read the summary first, a little confused, "Alien galaxy...... An asteroid hitting the sun? ”

This paper is obviously very important, otherwise it would not be possible to send it to his hands in such a troublesome form, Yu Ze carefully browsed it, although the whole paper has a very complex calculation formula, but many summaries and conclusions can be understood.

It is precisely because I can understand it that I am inevitably surprised.

He looked at the time carefully, and the time when the paper was written was ...... October 21, 2025.

"In 2025, more than two years from now?"

Yu Ze's palms unconsciously broke out in a lot of dense cold sweat.

What is the whole paper about?

In fact, it is not complicated, it is said that the astronomical community suddenly discovered that Pluto was disturbed by abnormal gravity, causing abnormal numerical changes in its orbit, and finally through astronomical telescopes and various calculations, at the heliosphere boundary of the solar system, a dwarf planet was found at high speed towards the solar system.

This menacing dwarf planet is extremely fast, with preliminary estimates exceeding 120 km/s, which is more than 2.5 times the speed of Mercury's orbit!

Naturally, this cannot be a dwarf planet in the solar system, not only is it extremely fast, but it is at least about 2,500 km in diameter, and the diameter is still above Pluto.

Therefore, there is only one possibility, and that is that it is a wandering dwarf planet from outside the solar system.

Don't look at the planets and asteroids in the solar system are well bound by the gravitational pull of the sun, but the universe is so big that the possibility of wandering planets and asteroids is not small in theory, and a rampaging dwarf planet is nothing.

The point is, this dwarf planet is heading straight for the solar system!

This is very scary, in case it hits the earth, human civilization will be finished, no, all life in the biosphere will be finished, the whole earth will be smashed into a super fireball, all the continents will cease to exist, turn into rolling magma, and life will naturally not survive.

The good news is that, according to the paper, after months of observations and precise calculations, the dwarf planet will not hit the Earth.

The bad news is that it will hit the sun directly.

The sun is the central celestial body of the solar system, accounting for 99.86% of the total mass of the solar system, not to mention a dwarf planet, even if the earth is placed next to the sun, it is not enough to see, so a dwarf planet hitting the sun is equivalent to a mosquito hitting humans at high speed, and humans do not even perceive the impact of mosquitoes.

But for humanity, this is a catastrophe.

The escape velocity on the surface of the Sun is 617.7 km, and if this dwarf planet hits it headlong, it will also be accelerated to close to this speed, so what happens to a dwarf planet with a diameter of about 2500 km or more hitting the Sun?

Obviously, when a meteorite hits the earth, it can hit a crater dozens of times its diameter, and hit hundreds of thousands, millions of degrees Celsius, let alone a dwarf planet, even if the impact area is only tens of thousands of ten-thousandths of the sun's surface area, it is still very terrifying.

According to the supercomputer simulation calculation of the paper, the mass of the dwarf planet was roughly calculated, because the impact speed was too fast and the mass was too large, the dwarf planet could not be broken by the Loch limit in time, and the energy generated by the impact reached 2.952*10^33 joules, which is equal to 7.71 million times the sun's full power output energy, such a powerful impact kinetic energy, roughly calculated is the energy of the sun to release 89 days.

89 days of solar energy does not seem to be much, but the amount of solar energy that the earth can receive is only 1/2.2 billion, and the energy of 1/2.2 billion is regarded as a whole, and the total energy consumed by human civilization must be multiplied by 1/9886 of this whole.

Therefore, the energy released by this impact, with the total energy consumption of human civilization, is enough to provide 1.67*10^20 years of energy for 8 billion human beings, and it will not be used up until the destruction of the solar system.

And this impact energy, even if 2.2 billion of the energy is transmitted to the earth, is more than 7 million times the usual total energy, in human terms, equivalent to the solar energy transmitted to the earth for more than 20,000 years, concentrated in one day to be released.

What will happen to the Earth, you ask?

Receiving such a high intensity of gamma rays, the earth's atmosphere will definitely not exist, the surface temperature can rise to seven or eight hundred degrees Celsius in just a few minutes, and the freshwater resources and marine resources must have all been evaporated, any living thing under such a terrifying gamma ray radiation and temperature, it will definitely die, no matter what viruses and bacteria on the surface of the earth can not survive, let alone large mammals humans.

No one is spared!

This is the end of life on Earth! It's not just humans!

The earth is sunbathed, the life on the surface is all gone, and this energy release is not released in an instant and then disappears, but in the next few years, the radiation against the earth will be thousands of times stronger than usual, cockroaches will not survive, and the earth will become a purgatory like Venus.

Yu Ze was so shocked by the conclusion of the paper that he lost his ability to think, and after a long time, he relieved himself and went to drink a glass of water first, barely calming his mind.

The time of the paper is October 21, 2025, and it has been 6 months since the discovery of the dwarf planet named "Grim Reaper", that is, the astronomical community spent 6 months to demonstrate and calculate, so the time to discover this dwarf planet is around April 2025, and there is still 1 year and 6 months to go.

This is normal, because the dwarf planet is so far away from the Earth that it has already entered the solar system, and it still flies at a speed of 120 kilometers per second, and it is still not discovered until Pluto's orbit is disturbed by gravity.
