"Let's go, according to the plan, even the nearest spaceship to the Centauri galaxy will take at least 50 years or so to reach the Centauri galaxy, the interstellar universe is too vast."

"It's still a bit too reluctant to talk about interstellar colonization with our current technology, and it's better to be able to research the warp engine technology."

Seeing the 8 spaceships disappear from view, Qin Yi also shook his head helplessly.

Humanity has not encountered any extraterrestrial civilization until now, which does not mean that there is really only human civilization in the void of the universe.

Scientists imagine that it is more likely that the starry universe is too vast, and the long distances that are often measured in light years have seriously hindered the communication and communication between galaxies.

Before science and technology have developed to a certain stage, and before the development of powerful and advanced spaceships, no one will go to the starry universe at all.

Even the current earthlings are already a second-level cosmic civilization according to the division of civilization, and they have basically separated from Jupiter and begun to develop in the home galaxy.

Even if there is a spaceship like the 'Emperor Wu of Han' now, which has all the conditions to sail in the interstellar universe, it is still difficult to talk about colonizing the interstellar universe.

The eight unmanned spacecraft sent out this time are unmanned spacecraft, so from the very beginning, its speed has been constantly accelerating, and the problem of acceleration has not been considered at all.

According to the scientists' setting, in the end, these eight spacecraft will eventually fly towards the nearest eight galaxies in the solar system at a speed of 30,000 kilometers per second, which is one-tenth of the speed of light.

One-tenth of the speed of light, which is an extremely remarkable speed, 30,000 kilometers per second, is also an extremely terrifying speed, but in the universe, this speed is still very, very slow, just one-tenth of the speed of light, and it will take 43 years to go to the nearest Centauri galaxy.

From here, it is known that navigating the interstellar universe requires not only faster speed, but also longer lifespan.

The average lifespan of earthlings is only over 70 years now, and it takes 43 years to travel to the Centauri galaxy at one-tenth of the speed of light, which may take more than half a century if it is considered the time to accelerate and decelerate.

Such a long time is almost equivalent to most of a person's life, starting from his youth and arriving at the Centauri Galaxy, he is already in his twilight years and is old and decrepit.

And no one knows whether there will be some other problems in this interstellar universe, which may be the biggest problem of interstellar astronautics.

Speed and time!

Space and time, to be precise.

"Warp engine, the Academy of Sciences is already conducting theoretical research, and the current progress is average, and in terms of materials, we estimate that at least degenerate materials are needed to meet the needs of warp engines."

"We have already solved the energy technology, and the huge amount of energy generated by controlled nuclear fusion technology is enough, and I estimate that we will not be able to develop warp engine technology at least for half a century."

When it comes to warp engine technology, Liu Peiqiang also shook his head and said.

Qin Yi has also taken out the relevant theories of warp engine technology, and scientists are working hard to study and research, which is the premise that there is something to learn and study, and he estimates that it will take half a century.

If there is no information from Qin Yi's side, this time is really difficult to say, maybe 100 years, 500 years, or even 1000 years are possible.

"I now understand that this life is widespread in the universe, but why haven't we encountered aliens yet, because the universe is so vast."

Liu Peiqiang let out a long sigh, only when he truly understands the vastness of the universe will he understand his own insignificance, and in the face of the vast universe, human beings are still turning in circles at the origin.

"Half a century?"

When Qin Yi heard this, he smiled, and then said: "It's good to be able to study it in half a century, but the key now is to lay a good foundation." ”

"When the foundation is solid, talents are like carp crossing the river, and then our science and technology can advance by leaps and bounds."

"Right now, it's still too small."

Qin Yi turned his head to look in the direction of Mars, the azure planet stood quietly in the void, exuding a misty halo, very beautiful and moving.

Looking at the more distant void, Qin Yi tried to find the location of the earth, but the distance between the current earth and Mars was too far away, and it was impossible to see the earth with the naked eye.

Looking further into the more distant Void Universe, it was pitch black, and a few bright stars were flashing brightly, Qin Yi knew that under this seemingly dark Void Universe, if you use the powerful cosmic astronomical telescope to look at it, 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, and the light of the stars spreads through the endless void, becoming extremely faint, and it is difficult to distinguish with the naked eye.

Only the most advanced telescopes of cosmic astronomy can distinguish these faint rays of light, analyze them, and know how far away the light comes from.

It is very likely that it is just a very ordinary beam of light, which has gone through hundreds of millions of years in the vast void of the universe, and all the light from the universe that human beings see now is actually the light of many, many years ago.

From this point of view, time and space, it seems to be very contradictory, and we do not seem to live in the same time and space as everything else in the universe, because what we are seeing now is a scene that I don't know how many billions of years ago.

Everything that is happening on our side now, through the distant void, when they see it, it has been a long time of unknown years.

"Time and space~"

These two words kept wandering in Qin Yi's mind.

"Why don't we go to the New Demon City and have a look?"

"It can also be regarded as a rest, just take a walk, the first batch of earth immigrants have arrived in the new magic city, just go over and take a look."

Liu Peiqiang nodded, and then thought about it and proposed.

"Okay, let's go."

Qin Yi came back to his senses and replied with a smile.

Soon, the three spaceships left the space factory and flew directly into Mars, heading towards the new magic city at the mouth of the Yangtze River in Middle-earth.

PS: Actually, it's really 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, and some of them are even millions of years ago. So people fantasize that the world we live in is not the real world? Could it be the same, in fact, we all live in an illusory world? What we see is not its true appearance, in the face of time and space, everything is illusory and unreal.
