In the life field, there is information one after another, and all the gatherers are paying attention to this matter, because a member of the race will have to go far away from them to a very far place, and even the light will have to walk for five years to reach the distance, and the total distance that the entire race has taken from nothing may not be as long as the journey that this race will embark on.

Because of this, the gatherers are doing everything they can to play a little bit of their part for the individual, the individual is giving everything for the group, and the group is also feeding back to the individual, so as to achieve a balance, about the risks that this sub-light journey may encounter, and what to do, and some mission requirements to use this sub-light speed travel to benefit the group, etc., this information fills the entire channel.

Temporarily at the end of the sub-light railgun's circum-equatorial sector, the navigator who is the protagonist of the sub-light voyage patiently listens to the messages delivered by his fellow people in the channel.

"When you go over there, you should be careful, the radiation energy of different stars will be different, you are new there, the available resources are very scarce, so you should pay special attention to this......"

Some collectors remind that although stars are all nuclear fusion reactions, there are significant differences between them, and the reason is that the difference in mass is caused by the difference in mass, stars with small masses, such as red dwarfs, will become very slow in fusion reactions, and the consumption of reaction materials will also slow down, resulting in a long lifespan, while stars with large masses are on the contrary, the fusion reaction is increased due to strong gravity, and the life span of stars is reduced in disguise.

The difference in fusion reaction causes the difference in energy release, and light is the most direct carrier of energy, so with the difference in the mass caused by the difference in the star leads to the difference in the output energy per unit time, and the energy level naturally affects the frequency of the electromagnetic wave that the star can release, and the two are closely related.

This is a very serious problem, different electromagnetic waves show different properties, so if it is a defense against low-frequency electromagnetic waves, when encountering high-frequency electromagnetic waves, the effect is not very good, and so on, for high-frequency electromagnetic wave defense, in the face of higher frequency electromagnetic waves, the performance effect will be unsatisfactory.

This is a problem that many sailors must be aware of, but in addition to......

"Don't worry about nutrient supply, a few years is for us onlookers, due to the shrinkage effect, the faster the speed, the slower the flow of time, so the subjective time of the sub-light speed sailing individual will not pass for a long time, it may only be a few minutes or hours, or a few days ......"

Some collectors explained what they might encounter after sub-light speed, although this was the first time they had never experienced sub-light travel, but mathematics does not lie, and the problems that may be encountered after sub-light speed travel can be obtained by putting forward hypotheses and deducing the logical relationships within the event.

The subsequent gatherer of information echoed the individual who illustrated the 'shrinkage effect' and supplemented it to deduce a possible danger scenario for sub-light travel.

"Yes, there is no need to worry about nutrients, but there are other problems, although sub-light speed navigation is the safest method of navigation known so far, but this method is still extremely risky, and the slowdown of the flow of time makes it impossible for the sailing individual to have enough time to deal with the unexpected situation encountered during the voyage......"

According to the theory of relativity, it can be known that the faster the speed, the greater the moving mass, and the matter itself slows down the passage of time because it reaches close to the speed of light, and this slowdown is a phenomenon caused by the distortion of space-time.

The direct manifestation of this is a phenomenon similar to the one in heaven and one year on earth described in ancient Chinese mythology.

However, unlike the Eastern Heavenly Court, sub-light objects and conventional velocity matter are still interconnected in space, so the interaction and interaction of matter still exists, which leads to the occurrence of a situation in which all material changes in the outside world are accelerating, from chemistry to physics.

Imagine that the observer himself stands still and watches a turtle crawling slowly and arduously in front of him, and when the observer accelerates to sub-light speed, he sees the slow turtle racing around at a speed of more than Mach 1,000 and is able to turn at an acute angle regardless of physical momentum, which is the effect of time slowdown.

And that's not all, the collector then explained, this time about radar detection.

"That's right, especially when the speed of light is reached, the radar effect will weaken the detection ability due to the constant speed of light, and if there is an obstacle in front of the route, such as an interstellar dust cloud, it will be a very serious disaster......"

No matter what kind of reference the speed of light is, it is maintained at a fixed value, even if there is a substance that can accelerate to the speed of light, the speed of light will not increase, this is the principle of constant speed of light, if an object is raised to the speed of light, the microwaves released by the object itself will be piled up in front of the object at the speed of light, until the object decelerates will be released.

The speed of sublight is not faster than the speed of light, so there will be no such accumulation, but the upper limit of the detection speed of the radar is also the speed of light, which also causes the distance that the radar wave can detect will become very short, so short that it is negligible, and by the time the radar feedback that there is an obstacle ahead, it is already too late, and it is impossible for the sub-light speed navigator to dodge it.

"Another thing you have to remember is that you are not alone, the community will always be your backing, if you encounter unsolvable difficulties, find a way to send a signal for help, we will find a way to help you, the community will not abandon any individual, unity makes us omnipotent."

……

Time passed minute by minute, but the information in the channel showed no sign of decreasing, and everyone was concerned about this fellow who was about to embark on a long and dangerous journey, but this goodbye should also be over.

Si shouted to the whole clan in the channel.

"Okay, it's all quiet, say goodbye here, don't waste time, the sub-light orbit segments have been warmed up, and the final preparations for the launch can begin."

Obviously, Si's words were very effective, and the channel was silent for an instant, and there was no superfluous information, except for the data collation and report of this sub-light speed voyage.

"Start Proofreading Route Parameter ......"

"Eliminate distractions ......"

"Introduction of Stellar Wind Interference Factor ......"

"Estimated Dangerous ......"

Every corner of the planet is releasing electricity, which is transported from all over the world through superconductors to charge the huge sub-light orbitgun, and the strong magnetic field accelerating around the equator even triggers magnetic storms that occur all over the world.

But that's not a problem for today's gatherers.
