Humanity is missing, luckily I have billions of clones.

Chapter 97 Bright Nebula

The long voyage continues.

This acceleration of only 1 centimeter per square second lasted for more than 90 days until the fleet's speed increased to 80 kilometers per second.

We can't accelerate any further. Accelerating further will consume more fuel, and decelerating in the future will also consume more fuel. By then, we might need to use emergency fuel reserves.

The acceleration that had lasted for more than three months came to a halt, and the entire fleet completely lost gravity.

Because of this acceleration of 0.01 meters per square second, the cabin of each spacecraft has remained extremely stable during this period of time, which is approximately equivalent to one thousandth of the gravity on Earth.

At this moment, the acceleration stops and the vehicle enters the state of inertial navigation, so even this little bit of gravity disappears.

Everything was no longer placed stably in its original position, and all unfixed objects were suspended in the air.

Including clones.

Among these 1500 million clones, except for the 50 clones who are on duty in the fleet and maintain daily navigation, the remaining 1450 million clones lie on densely packed beds all day long with nothing to do to rest.

There is only one hour a day, and Li Qingsong will control them to move around to prevent the degeneration of their muscles and body functions.

Originally they could still lie down, but now without gravity, they can only float.

Not only them, but the entire fleet is also suspended at this moment, suspended in this endless sea of stars.

No matter which clone's perspective Li Qingsong switched to, no matter which porthole Li Qingsong looked out from, he saw almost the same starry sky.

In the past hour, day, or even month, the external environment has hardly changed.

Sometimes he couldn't help but doubt emotionally whether he was moving at a speed of 80 kilometers per second or was really standing still.

Of course, every time, his reason told him that he was indeed moving forward at an unprecedented speed.

It’s just that the starry sky is too vast and there is no reference object, so no matter how fast you fly, it seems like you are standing still.

The fleet sailed as if it were stationary.

The fleet had limited supplies and was unable to conduct any scientific experiments or research. However, this did not prevent Li Qingsong from manipulating the clones' brains to think.

Anyway, idle is idle.

Therefore, many problems accumulated during the long research period finally had the opportunity to be solved during this voyage.

More than ten million brains are thinking about these problems at the same time, looking for inspiration to solve them. They sleep when they are sleepy, eat when they are hungry, and continue thinking when they wake up, repeating this process.

At the same time, Li Qingsong took advantage of the free time and the opportunity that the fleet's speed and course had stabilized to take out all the space optical telescopes, radio telescopes, etc., and threw them directly into the starry sky, allowing them to start a new round of sky observations.

Li Qingsong doesn't even need to fix these space observation equipment.

Place them about 1000 kilometers away from the fleet, adjust their initial state to be stationary, and then you don't need to worry about them anymore. They will always stay there and maintain a fixed distance from the fleet.

Of course, it looked like they were stationary, but in reality, these devices and fleets were all moving towards the inner solar system at a speed of 80 kilometers per second. It was just that their speed and course were exactly the same, so it looked as if they were all stationary.

Dozens of space optical telescopes and dozens of space radio telescopes were each aimed at a piece of the sky, conducting observations day and night.

As a result, a large number of strange astronomical events that Li Qingsong had never seen before came into his sight.

Black holes, neutron stars, white dwarfs, nebulae and star clusters, extragalactic galaxies, quasars...

Etc., etc.

Li Qingsong knew that when science and technology developed to a certain level, if it wanted to continue to improve, it would be inseparable from astronomical observation.

There are too many basic physics theories that need to be proven from astronomical events.

It's just that over the past few hundred years, I've been busy with lower-level development and haven't paid much attention to space. These past few years have been a good time to make up for it.

So, time slowly passed by in the long observation and thinking, the review of the theoretical knowledge that had been mastered, and the speculation and conjecture about the knowledge that had not been mastered.

In front of us, the brightness of the sun has increased from only being able to cast a dim shadow on Luoshen to now being as bright as the moon seen from Earth.

Of course, it's just brightness, not size.

In fact, the sun that Li Qingsong saw at this moment was still just a small dot of light, without any disk-like structure at all.

This seemed to be the only visible change during the years of sailing. Everything else remained unchanged.

At least not noticeable to the naked eye.

"We'll be crossing Pluto's orbit in another month. We're finally almost there."

One day during the long voyage, Li Qingsong was filled with emotion, feeling the vastness of the universe and the length of the journey.

The journey from the edge of the solar system to the inner solar system is already so long.

The distance between the sun and the nearest star is about 4.2 light years.

This number is about 2500 times the voyage he is currently on.

It was only a 2500/ voyage, but I had already tried my best.

The vastness of the universe cannot be measured by one thousand or ten thousand 4.2 light-years.

"I don't know when I can truly travel in this vast universe."

Li Qingsong yearned and sighed.

Hundreds of telescopes are still suspended around the fleet, exploring outer space non-stop.

During this exploration, Li Qingsong suddenly discovered a slightly strange celestial body.

Judging from its shape, it should be a nebula.

A nebula is a cloud of matter formed by the gathering of interstellar dust, hydrogen, helium, and other plasmas.

Nebulae are ubiquitous in interstellar space and are extremely numerous, ranging in size from large to small. Large nebulae can nurture thousands or even tens of thousands of stars, while smaller ones are obscure and almost invisible to humans.

Nebulae can be roughly classified into bright nebulae and dark nebulae according to whether they emit light.

At this moment, what Li Qingsong saw was a bright nebula.

In visible light, the nebula emits a hazy glow.

But Li Qingsong remembered clearly that the last time his space telescope observed this direction, he saw nothing.

But a nebula cannot travel such a long distance in such a short time. It is unlikely that it flew from somewhere else in just a few years.

Then there is only one possibility left.

There must be some reason that caused it to change from a dark nebula to the bright nebula it is today.

What could be the reason?
"This small nebula is only five or six light-years away from the solar system, very close.

This direction... is the direction where the Gliese 625 galaxy is located."

The Gliese 625 galaxy is also called the Bluetook Galaxy by the Bluetook people.
