Chapter 476 (1/2)

Sure enough, as Zhang Heng looked at the source of the sound with his empty eyes, he saw a ball of light twisted beyond description approaching in the sky. At the moment of the other party's appearance, those dark shadows outside the spaceship seemed to have encountered natural enemies and retreated in panic like the tide!

It seems that the indescribable thing coming from afar is the real king of subspace. Even the most essential malice should fear each other and make way for each other!

Even, I do not know how many thousands of kilometers away that huge and strange flowers, also in this moment Susu Shuo up, then the petals quickly closed, like a frightened hedgehog, completely shrunk into a tiny flower!

”What the hell are you?”

Zhang Heng was surprised. He didn't feel flustered because the target of the other party was himself. He kept staring at the distance with his eyes open. However, in his heart, the sense of crisis became stronger and stronger. He had a feeling that the moment he saw the other party thoroughly was the moment of his death!

Thinking of this, Zhang Heng couldn't help shaking his head and taking a deep breath of airway, ”the star of dimension, return.”

Suddenly, Zhang Heng only felt a flower in front of his eyes. When he regained consciousness again, he had already left the sub space with the whole experimental spaceship and returned to the material world.

Finally, cautious, he still did not choose to take risks to face the unknown.

According to the data collected in the experiment, Zhang Heng's scientific team began to study the unknown and mysterious space. At the same time, the feasibility of sub space navigation has also been verified, followed by hundreds of large spacecraft that can cross the sub space began to enter the manufacturing stage.

These spaceships have no cockpit and are all replaced by sleeping chambers. The advantage of this is that when flying, people can spend a long voyage in the form of sleep, and there will be no tragedy similar to ”deep space amnesia” because of deep space claustrophobia. Moreover, they can also increase the carrying capacity of population by 10 times and 100 times. On the day when the curse comes, if human beings are really irresistible Each other, then these spaceships will carry tens of millions of human beings into the sky, heading for the further deep space of the universe, to pursue the vitality.

This has been Zhang Hengren's most righteous move. Originally, Zhang Heng had plans to send people to explore other stellar systems for human beings, but this plan was immediately cancelled with the calculation of a set of data by Yuehua. Even if the sub space voyage is officially put into use, it will take half a year for human beings to fly to the nearest star system Alpha Centauri, which is the closest to the solar system. If we add in the return, I'm afraid that the curse will come long before we return to earth, and the time will be too late.

However, the distance is not as simple as one plus one. In fact, the further the distance between the starting point and the destination is, the average time spent on sailing will be reduced geometrically. With the technical ability of star technology, the ordinary speed of a spacecraft is only about 100 kilometers per second. After constant acceleration, it can accelerate to thousands of kilometers per second in a day, reaching this speed After that, it costs a lot to increase the speed every time.

According to Einstein's theory of relativity, as the speed of the object increases, the mass of the object will continue to increase, and when it approaches the speed of light, the mass will be close to infinity! In other words, the faster the speed is, the higher the cost of acceleration is. The spacecraft can accelerate to 100000 km / s in one year, and can barely accelerate to the speed of infinitely close to the speed of light, that is, sublight speed in 40 or 50 years.
