Voyage of the Stars

Now humans don’t know whether the energy acquisition method of level 5 civilization will change, but one thing is certain, that is, level 6 civilization also needs to use stellar energy, or in other words, at the level of level 6 civilization, stellar energy is still the easiest energy to obtain in the universe.

Otherwise, the pioneers would not have stuffed so many red dwarfs into the small universe. If level 6 civilization is like this, level 5 civilization must also be inseparable from stars.

In this case, Dyson Cloud or Dyson Sphere still has its value, but this project will take a long time for the Star Alliance to do. After all, there is no rush now, so they will build while wandering. Anyway, antimatter can also use heavy nuclear fusion as energy, and heavy nuclear fusion only needs stones to burn. Almost every normal star system in the universe has a lot of rocks, which can be squandered at will.

Of course, the acquisition efficiency and convenience are definitely not as high as the mobile Dyson Cloud and Dyson Sphere.

In this way, when the Lyra returned to space again and entered the warp speed, it also marked that humans took the entire Star Alliance away, in a place where the Deep Blue Stars could not see.

As for the next destination, humans have no specific purpose. It is probably to find a star system to stop when the fuel is almost enough, replenish antimatter fuel, and then continue to embark on interstellar voyage.

Stop and go, if there is a chance, find out about the murderer who destroyed the solar system. Of course, the most important thing at this stage is the breakthrough of basic theory.

That is the theory of everything, which is the theory that humans must master to improve again. It is the symbolic theory of level 5 civilization. Human civilization is no longer Wuxia Amon. After contacting many civilizations, humans have known that the power foundation of almost all level 5 civilization applied technology is the theory of everything.

That is the theory that truly unifies the four fundamental forces.

After reaching level 4 civilization, humans have been doing research and exploration in this area, but from the primary stage of level 4 civilization to the top stage, there is still no clue, and gravity is still so stubborn.

The grand unified theory mastered by the fourth-level civilization does not include gravity, but it can travel at warp speed in the form of a grand unified force field through some equivalent effect. However, no matter how powerful the force field is, such a warp speed always has a maximum value, that is, 38.941 times the speed of light. Humans have been able to break through it by relying on the special technology of pioneers, but it is only 50 times the speed of light.

There is no possibility of going further, which is not something that the grand unified force field can do.

So there is only one way out for civilization, that is, the theory of everything.

Basic theory is different from applied technology. After all, most applied technologies still have a direction. As long as you use perseverance and perseverance to keep trying and making mistakes, you will be able to find it one day, but basic theory is not like this. Sometimes it only needs mathematical deduction to make progress, and sometimes it requires real progress in basic physics, such as discovering new particles.

It is also very accidental and relies heavily on the subjective initiative of intelligent life.

So there will be a situation where many civilizations cannot find new power no matter how hard they try, just like the technological barriers that humans have encountered time and time again. Sometimes they are about to doubt themselves, but suddenly they find it, which is simply unreasonable.

The current situation is similar to that of the past, or even worse.

For many years, human scientists have been committed to this and have proposed many ideas for realizing the theory of everything. They have always had several ideas.

One is the old way, just like the grand unified theory, to include gravity in the four fundamental forces system for unification, build a super invincible particle collider, use the most violent way to collide the environment of that energy level, and then analyze the super collider collision results, and reverse the principle based on the experimental results.

Obviously, this method does not work. Not to mention humans, even a level 6 civilization does not have the ability to build a collider billions of light years long.

The second is the quantization of gravity. Scientists try to find a way to quantize gravity by expanding the loop quantum gravity theory, so as to find the theory of everything. String theory is the most successful force in quantizing gravity, which also involves many related theories, such as supersymmetric gravity, microscopic extra dimension theory, hyperspace, general relativity, quantum field theory, etc.

But that is to say, if we cannot innovate, then the probability of human beings finding the theory of everything is equal to zero, because at the fourth level of civilization, the previous theories on Earth can no longer keep up. Although some ideas are still advanced and can still be used, they are no longer involved in specific mathematical processes.

In other words, the various theories of the Earth era only pointed out a general direction for humans. If you want to realize it, you have to keep groping in the dark.

The third is the creation experiment, which is to create an environment in which the four fundamental forces have not yet broken their symmetry. This is just as unrealizable as the first point of view, so the scientists who put forward this point of view changed their thinking. They believe that finding primordial gravitational waves is the same.

Primordial gravity is the afterglow of the Big Bang of Genesis. Scientists believe that finding primordial gravitational waves may help human civilization trace back to the extremely short and extremely rapid expansion period at the beginning of the creation of the universe.

So how to find primordial gravitational waves? Scientists have proposed two solutions: one is to look for it through observation of cosmic microwave background radiation, and the other is to look for primordial black holes.

After the period when the four fundamental forces were unified, the universe expanded by 10 to the 26th power in only about 10 to the negative 33th power seconds, and the temperature instantly dropped to one hundred thousandth of the previous temperature.

Scientists believe that as long as they can find a trace of clues, it is possible to help humans deduce the theory of everything.

Yes, they are all "possible, possible, or perhaps", and no one dares to say it with certainty.

This method is indeed possible to find, but the conditions are also very harsh. God knows where the so-called clues are in such a vast universe, and no one dares to guarantee that the current universe or the Milky Way still has natural clues at the beginning of the Big Bang.

There is no need to think about outside the Milky Way, as humans at this stage will definitely not be able to get out.

But where are these clues!

According to the Big Bang theory, at the beginning of time, the universe is in a singularity state. This is a point with infinitely small volume, infinite density, and infinitely high temperature. There is no difference between space and time at this moment.

At the moment of the singularity, all physical properties and physical theories such as general relativity, quantum mechanics, and even the concept of rules are not applicable.

The period from the singularity to 10^-43 seconds is called the Planck period. That is, 5.344 seconds, which is the smallest unit of time defined by quantum mechanics. The distance a photon travels in one Planck time is one Planck length. But it is worth mentioning that at this moment, the photon has not yet been born, and the radius of the universe at this moment is about 1 Planck length.
