A group of faster-than-light organisms developed by amoeba depart from the neighboring stars of the group's parent star and end up in the home star system where Twilight is located.

The faster-than-light state is not the same as the sub-luminal state, and there is no star rainbow phenomenon, because at this moment, the relative speed of the creatures has exceeded the speed of light, and they catch up with the light emitted earlier than before departure, so it will have the effect of 'time rewinding', and intuitively speaking, it seems that the entire universe is moving away from faster-than-light organisms.

This kind of 'time rewinding' is not really going back in time, but just browsing the information of the past.

The situation is different from that at sub-light speeds, but there are similarities, that is, as in sub-light speeds, you are still 'blind' in the sailing state.

Although you can see the information of the past, the space-time of the universe is always expanding, so this information will be distorted by space-time, and the stars in the sky seen by faster-than-light creatures are showing a 'contracting' trend, and considering the movement of various celestial bodies, the risk of using past information as a reference coordinate is undoubtedly very high.

As shown in science fiction movies and television, faster-than-light creatures suddenly appear in the parent star system in the way of 'teleportation', accompanied by waves of ripples in time and space.

It's not really teleportation, it's just that after exceeding the speed of light, the light that the faster-than-light creatures themselves scattered can't catch up with the faster-light creatures, and reach their destination before those lights.

In the parent star system, the Hogu were waiting for the return of the faster-than-light creatures, and this time the experiment was to have them swarm the nearest star system in front of them, and then return from there.

Through radar waves and the active broadcast of information by the tachyon creatures, the Hogu were the first to learn of the location of the tachyon creatures.

After entering the parent star system, the faster-than-light creatures poured out a large amount of negative matter, leaving only a small amount of negative matter, and continued to travel towards twilight at a low speed of light with the help of universal repulsion.

Yes, the way to distort space-time is not to travel only faster than the speed of light, but also below the speed of light, and it does not require any propellant to be consumed, so the specific impulse formula is meaningless.

Looking at the radio messages transmitted back by the faster-than-light creatures, Twilight couldn't help but admire.

To put it more realistically, it's like magic.

If you don't delve into the principle, it's just a simple accident, and the faster-than-light creatures are like getting a huge amount of energy out of thin air to carry out 'faster-than-light displacement' and 'instantaneous deceleration without inertia'.

The momentum of matter seems to be placed or taken by an invisible hand of God, subverting the three views of the masters of classical mechanics 100%.

"Yes, the movement of living organisms no longer requires matter to carry out, so there is no longer a need to carry a large amount of propellant, and even the energy consumption is negligible, which is a real non-working fluid propulsion."

"I used to think that the real sense of non-working fluid propulsion is just a myth that is difficult to realize, and deep space navigation always needs material as a medium."

From the primitive to the high-temperature jet of a chemical rocket, to the pulse tail flame released by the annihilation of positive and antimatter, in essence, they all follow the third law of mechanics - the action and reaction forces between two interacting objects are always equal in magnitude and opposite directions, acting in the same straight line.

Following the third law of mechanics, the spacecraft ejects material backwards, thus obtaining a propulsion force of equal magnitude and opposite direction in the same straight line as the ejected material.

It is too difficult to jump out of this framework, if it were not for the gatherers who unearthed the relics of the Hui civilization and confirmed the existence of negative matter, I am afraid that amoeba would have a long detour to take.

Hogu's unscrupulous statement drew Twilight's correction, but Twilight still had her own doubts.

About the tachyon creatures encountering obstacles during their voyages

"It is not like this, the speed of light is the space-time around the organism, the speed of light limit of space-time to matter has not changed, and the matter encountered when traveling faster than light is equivalent to being dragged by the gravitational force of the gravitational ring in front of it and impacting, which is very powerful, but at least it will not exceed the energy release of the sub-light speed collision."

"Of course, it will be disconnected, the rope as a static mass object, it is impossible to move faster than the speed of light, and the displacement speed of organisms in distorted space-time is indeed faster than the speed of light, this difference is equivalent to the rope is bearing the tearing force caused by the expansion of space-time, the rope can withstand it, the displacement of the organism cannot exceed the speed of light, the rope can not withstand the disconnection, and the organism can carry out the speed of light."

Hogu explained its understanding of faster-than-light, and then it noticed something different about the faster-than-light creatures that they had set off.

The organisms are arranged in a quadrangular pyramidal structure, which is hollow and only thin on the inside.

"Why do you stay in this formation?" Hogu asked.

"Will, our radio communication scheme is wrong, we have actually tried, and we cannot establish any communication with our fellow clan in the direction of 180 degrees of the length of the central axis of our keel."

"Isn't it the same direction and the same speed?" Huo Gu was stunned.

"It is the same direction and the same velocity, which should be relatively stationary, but we still mistakenly substitute the inertial frame, and after the electromagnetic waves exceed the distorted space-time, they cannot catch up with the same family that is speeding faster than light."

Huo Gu came to his senses, "So this is your solution?" ”

"Yes, with such a quadrangular pyramid array, the individuals in the head can relay radio messages to their peers in the rear to ensure the transmission of information."

"But how can individuals in the rear carry information to the front?"

Group communication is necessary, especially for interstellar travel, and if you encounter difficulties in a complex environment, you need to brainstorm more comprehensively, so that you can consider the problem more comprehensively.

Collectors have their solutions.
