With the Sun as we know it, 32,616 light-years away, is a huge stellar graveyard, the core of the Milky Way.

It is so glorious that it is impossible to look at directly, but it is full of the smell of death.

Countless red giants have spent the rest of their lives here. They danced the dance of death around the giant invisible black hole at the center of the Milky Way.

If you are not careful, the dance steps under your feet are a little slower, and you will be swallowed by the black hole, bursting out with the brightest light in your life, and then forever silent.

Or, in another universe far away, erupted by a wormhole and restarting the life of a nebula.

"Passerby 7825" is a huge ovoid object, the surface is full of protrusions and various attachments, with three long cantilevers in front and behind,

In front of it, the cantilever holds a huge ring, in which is a membrane formed by the eruption of plasma, from which half of the ring ejects and is received by the other half.

All kinds of interstellar matter in front of "Passerby 7825", if the mass is not enough for "Passerby 7825" to avoid, will be intercepted by this plasma membrane.

The second half of the "Passerby 7825" is also a parabolic membrane supported by a cantilever arm, an extremely thin and hard material, supporting a huge sail.

In the center of the sail, there are occasional bursts of light, which are bursts of energy bursts from a small annihilation reaction, hitting the sail, allowing the "Passerby 7825" to accelerate to 0.5 times the speed of light.

Fly past the interstellar dust, from the direction of the core of the Milky Way, towards the border of the Milky Way.

Between the core of the solar system and the Milky Way, near the constellation Centauri, there is a huge dark nebula, which is scattered in the cold and dead universe, blocking most of the starlight,

If the core of the Milky Way is like a giant eye, vigilantly watching the starry sky around it, then this dark nebula is like a thick cloud that absorbs most of the light.

This dark nebula is so dense and abrupt that it seems to have been created by some kind of intelligent life, consciously blocking the solar system and avoiding the gaze of the Milky Way core.

Dot, dot

Stroke, stroke, stroke...

As a polite visitor, the "Passerby 7825" continuously sends pulsed signals at the radio frequency of 1420Mhz (1420 MHz is the transition frequency of neutral hydrogen and is considered a universal cosmic channel).

For the existence of all universes, time is a basic element, energy is also a basic element, time can be measured, and it is unchanged across the universe, 2 times the time is twice the time, even if it crosses the universe.

It's not the same with energy, energy can decay, and no one can use energy to carry information. Therefore, dots, strokes (dots of twice the time) constitute the basic information encoding.

Apparently, the maker of this silver object, uses octal system.

The "Passerby 7825", which uses annihilation reactors as an energy source, has been sailing alone in space for 30,000 years. Maybe it will continue to sail for another 30,000 years.

On this day, the Kuiper Belt, 40 astronomical units from the Sun, the true frontier of the solar system, is home to a large number of frozen asteroids.

Passerby 7825 passed through the dark nebula and after a long journey approached the galaxy, which was obscured by dense fog. The 7825 turned around, aimed its sails at the sun, and began to slow down.

The Kuiper Belt is an icy asteroid formed by the primordial nebulae of the solar system that contains the earliest secrets of the galaxy.

"Passerby 7825" approached one of them, and from the cantilever, two mechanical arms were stretched out to capture the dirty snowball.

"Ingredients, hydrocarbons"

"There is a possibility that there is some kind of carbon-based life in this system"

"Passerby 7825" adjusted its direction, and the huge rings of Jupiter immediately caught the attention of observers, as a candidate sun for the solar system, Jupiter has its own large family of moons.

Callisto is the largest of these, and sensors from the Passerby 7825 have detected the presence of some sort of carbon-based liquid on Callisto.

After several days of flying. Passing over Callisto, the 7825 moon has an ocean of liquid methane, but the temperature of the moon is too harsh for life because it is too far from the sun.

The number three seems to have a unique charm. Three points are needed to support a stable plane, and Earth happens to be the third planet in the solar system. Venus is too close, the sun has baked it,

Mars is too far away for the sun to be warm enough for him to have liquid water on his surface, perhaps beneath the crust of Mars. However, "Passerby 7825" has no care about detailed detection,

A huge azure planet that attracts all the attention of "Passerby 7825".

"There are stable hydrocarbons",

"There's a lot of liquid water there"

"Oxygen content 15%"

"Carbon-based life has been discovered!"

"No signs of unnatural creation found"

"There is no sign of intelligent life"

"Passerby 7825" released all its probes, and dozens of oval flying objects left the interstellar vehicle and entered the Earth's atmosphere. The images and various data collected by them are collected in the central database of "Passerby 7825".

This is a blue planet, mainly composed of oceans, several meters high waves, so that the planet is full of vitality, the depths of the ocean, all kinds of creatures are reproducing, living or dying,

The land was occupied by dinosaurs, creatures at the top of the food chain, whose survival instinct drove them to hunt, eat, reproduce and evolve.

Even in the sky, flying dinosaurs appeared, and although their wings were so clumsy because they had no feathers, flying still made them more powerful.

"Countless beings, in order to survive, keep hunting, capturing prey or becoming prey, constantly making themselves stronger

"The naked law of nature, how many years have I not seen this scene."

Several intelligent cores of the "Passerby 7825", constantly exchanging opinions, they are the masters of this aircraft, and they vote to make decisions on the behavior of the "Passerby 7825".

"Similar to Alpha Planet 3 in Vega"

"There is a 98.75% chance of evolving a high level of maritime civilization"

"It is also quite possible to repeat their tragedy, the level of intelligence far exceeds the limits of the physical capacity, and after the high development of mental power, genocide."

"It could be a big problem"

"The probability of naturally forming intelligent life without faction attributes is close to 78.25%"

"Let's vote on the probe's action strategy"

1. Do not interfere with the course of life

2. Do not show your own existence

After a month of collecting data and collecting a large number of DNA samples, the probes returned to the mothership. The Passerby 7825 turned around, aimed its sails at the sun, and using the solar wind and a small annihilation reaction, the Passerby 7825 began to accelerate, continuing its journey that had been going on for 30,000 years.

Except for one of them.

This probe alone enters the orbit of the Earth's satellite, the Moon, and slowly descends on the far side of the Moon. Finally, land in the middle of a crater with a diameter of one kilometer,

The probe burrowed into the ground, turned off 99% of the equipment, and began to go into hibernation, with only a triangular silver antenna exposed on the surface of the moon, facing the direction of the Milky Way's core, and began a long, and most likely permanent, wait.

Let's call it Godot.
