Vol 3 Chapter 5: ,time and space

"Let's go. According to the plan, even the nearest spaceship to the Centaurus galaxy, it will take at least 50 years to reach the Centaurus galaxy. The interstellar universe is really vast."
"Talking about interstellar colony with our current technology still seems a little too reluctant. It is better to study the curvature engine technology."
Qin Yi shook his head helplessly as he watched the eight spaceships disappear into view.
Humans have not encountered any alien civilization until now. This is not to say that in the cosmic void, only human civilization exists.
Scientists imagine that the greater possibility is that the starry universe is too vast, and the long and distant distances calculated in light years have seriously hindered the exchanges and interactions between galaxies.
Before science and technology have reached a certain stage and no powerful and advanced spacecraft has been developed, no one will go to the starry universe at all.
Even today's Earth people, according to the division of civilization, is already a level 2 universe civilization, basically separated from Jupiter, and began to develop in the parent galaxy.
Even if there is a spaceship like the 'Hanwu Great Emperor' now, it has all the conditions to sail in the interstellar universe, but it is still difficult to colonize the interstellar universe.
The eight unmanned spacecrafts dispatched this time are unmanned spacecrafts, so from the beginning, its speed has been continuously accelerating, and the issue of acceleration has not been considered at all.
According to the settings of the scientists, eventually these 8 spacecraft will fly towards the nearest 8 galaxies of the solar system at a speed of 30,000 kilometers per second, which is one tenth the speed of light. .
One-tenth the speed of light. This is an extremely fast speed. The speed of 30,000 kilometers per second is also extremely terrible. But in the universe, this speed is still very, very slow. This is just the speed of light. One-tenth, it takes 43 years to travel to the nearest Centaurus galaxy.
From this we can see that sailing in the interstellar universe requires not only faster speed, but also longer life.
The average life expectancy of Earth people is now only 70 years old. It takes 43 years to go to the Centaurus galaxy at one tenth the speed of light. If it is accelerated and decelerated, it may take more than half a century.
Such a long period of time is almost equal to a person's lifetime. When he left in his youth and reached the Centaurus galaxy, it was already twilight and old.
And if there are any other problems in this interstellar universe, and no one knows, this may be the biggest problem in interstellar universe navigation.
Speed ​​and time!
To be precise, it should be space and time.
"Curvature engines, the Academy of Sciences is already conducting theoretical research. The current progress is general, and in terms of materials, we estimate that at least degenerate materials are needed to meet the needs of the curvature engines."
"We have already solved the energy technology. It is enough to have the huge energy produced by controlled nuclear fusion technology. I estimate that we will not be able to study the curvature engine technology for at least half a century."
Talking about the speed engine technology, Liu Peiqiang also shook his head.
Qin Yi's relevant theories of the engine technology have also been taken out here. Scientists are working hard to learn and research. It is estimated that it will take half a century to learn and research.
If there is no information from Qin Yi, this time is really hard to say, maybe 100, 500, or even 1000 years are possible.
"I now understand that this life is widespread in the universe, but why haven't we met aliens so far, because the universe is so vast and immense."
Liu Peiqiang sighed a long time. Only by realizing the vastness of the universe can he understand his smallness. In the face of the vast universe, human beings are still circled at the origin.
"Half a century?"
Qin Yi heard it, smiled, and then said: "It is good to be able to study it for half a century. The key now is to lay the foundation."
"The foundation is solid, and talents are constantly emerging like river carps, so that our technology can advance by leaps and bounds."
"Right now, the population is too small."
Qin Yi turned his head to look at Mars. The blue planet stood quietly in the void, exuding a halo, very beautiful and moving.
Looking at the more distant void, Qin Yi tried to find the location of the earth, but now the distance between the earth and Mars is too far away, it is impossible to see the earth with the naked eye.
Looking into the more distant void universe, it is dark, and a few bright stars are shining. Qin Yi knows that under this seemingly dark void universe, if you look at it with a powerful cosmic astronomical telescope, you You will find that it is also very prosperous and bright.
Even if it is a small, very small, very dark area, it also has countless stars, but the cosmic void is too vast. The star's light has passed through the endless void, becoming extremely weak, with the naked eye. It's hard to tell at all.
Only the most advanced cosmic astronomical telescopes can distinguish these faint rays, analyze them, and then know how far away the stars come from.
It is very likely that it is just a very ordinary beam of light. It has gone through billions of years in the vast cosmic void. All the light from the universe that humans see now is actually a lot. , Many years ago.
From this point of view, time and space are very contradictory. It seems that we and everything else in the universe do not live in the same time and space, because what we are seeing now is unknown how many billion years ago Sight.
Now everything that happened on our side is separated by a distant void, and when they saw it, they had passed a long and unknown years.
"Time and space ~"
Qin Yi's mind kept lingering on these two words.
"Should we go and see in the new magic city?"
"It can also be regarded as a break ~ EbookFREE.me ~ just walk around, the first batch of earth immigrants have arrived in the new magic city, just look at it in the past."
Liu Peiqiang nodded, then thought and suggested.
"Okay, let's go."
Qin Yi turned around and smiled back.
Soon, the three spacecrafts left the space factory, flew directly into Mars, and flew towards the new magic city of the small Yangtze River estuary in Middle-earth China.
PS: It ’s actually very interesting to think about it. The sun we see now is the sun 8 minutes ago, and the starlight we see at night is the light of many years ago, some even a million years ago Light. So people imagine that the world we live in is the real world? Will it be the same, in fact, we are all living in an illusory world? What we see and see is not its true appearance. In the face of time and space, everything is unreal and unreal.
