Voyage of the Stars.

Chapter 865 Where is the Theory of Everything?

Now humans do not know whether the way level-five civilization obtains energy will change, but one thing is certain, that is, level-six civilization will also use stellar energy, or in other words, at the level of level-six civilization, stellar energy will still be the most easily obtained energy in the universe.

Otherwise, the pioneers would not have stuffed so many red dwarfs into the small universe. If this is the case for a level 6 civilization, then a level 5 civilization certainly cannot do without stars.

In this case, the Dyson cloud or Dyson sphere still has its value, but the Star Alliance will have to work on this project for a very long time. After all, there is no rush now, so they can just wander and build at the same time. Antimatter can also use heavy nuclear fusion as energy anyway, and heavy nuclear fusion only needs stones to burn. Almost every normal star system in the universe has a large amount of rocks, which can be wasted at will.

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

Just like that, when the Lyra returned to space and entered warp speed again, it also marked that mankind had taken the entire Covenant away, where the Deep Blue people could not see.

As for the next destination, humans have no specific purpose. It is probably to stop at a random star system when the fuel is almost used up, replenish antimatter fuel, and then continue their interstellar voyage.

We will stop and go, and if there is a chance, we will find out about the murderer who destroyed the solar system. Of course, the most important thing at this stage is to make a breakthrough in basic theory.

That is the theory of everything, or the theory of everything. This is the theory that humans must master to advance again, and it is the hallmark theory of the fifth-level civilization. Human civilization is no longer a mediocre one. After coming into contact with many civilizations, humans have come to know that the power foundation of almost all fifth-level civilization applied technology is the theory of everything.

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

After reaching the fourth level of civilization, humans have been conducting research and exploration in this area, but from the initial stage to the top stage of the fourth level of civilization, they still have no clue, and gravity is still as stubborn as before.

The grand unified theory mastered by the fourth-level civilization does not include gravity, but it can achieve warp travel through a certain equivalent effect in the form of a grand unified force field. However, no matter how powerful the force field is, the warp speed always has a maximum value, which is 38.941 times the speed of light. Humans have been able to break through this with the help of the pioneers' unique technology, but it is only 50 times the speed of light.

There is no possibility of going any further, as this is not something that the grand unified force field can achieve.

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

Basic theory is different from applied technology. After all, most applied technologies have a direction. As long as you have perseverance and persistence to keep trying and making mistakes, you will figure it out 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 the discovery of new particles.

It is largely accidental, but also relies heavily on the subjective initiative of intelligent life.

As a result, 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 in the past. Sometimes they are about to doubt themselves, but suddenly they realize that it simply does not make sense.

The situation now is similar to what it was then, or even worse.

For many years, human scientists have been working on 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, which is to include gravity in the four fundamental forces system for unification, build a super particle collider, use the most violent method to collide the energy level environment, and then analyze the super collider collision results to reverse the principle based on the experimental results.

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

The second is the quantization of gravity. Scientists try to find a way to quantize gravity by expanding loop quantum gravity theory, so as to find the theory of everything. String theory is the most successful force in quantizing gravity theory, which also involves many related theories, such as supersymmetric gravity theory, microscopic extra dimension theory, hyperspace, general relativity, quantum field theory, etc.
But the point is, if we cannot innovate, then the probability of humans finding the theory of everything is zero, because at the fourth level of civilization, the previous theories on Earth are no longer up to date. Although some ideas are still advanced and can still be used, they are no longer available when it comes to specific mathematical processes.

In other words, the various theories of the early Earth era only pointed humans in a general direction. If they want to achieve it, they still 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 undergone symmetry breaking. This is as impossible to achieve as the first point of view, so the scientists who proposed 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. Scientists believe that finding primordial gravitational waves may help human civilization trace back to the extremely short period of extreme expansion at the beginning of the universe.

So how do we find primordial gravitational waves? Scientists have proposed two solutions: one is to find them through observations of the cosmic microwave background radiation, and the other is to find primordial black holes.

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

Scientists believe that if they can find even a tiny clue, it may be possible for humans to deduce a theory of everything.

Yes, they all said "maybe, possibly, perhaps", and no one dared to say it with certainty.

This method may indeed be able to find the answer, but the conditions are also very harsh. In such a vast universe, who knows where the so-called clues are, and no one can guarantee that the current universe or the Milky Way still has natural clues from the beginning of the Big Bang.

There is no need to think about going outside the Milky Way. 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 was in a singularity state. This is a point with infinitely small volume, infinite density, and infinitely high temperature. At this moment, there is no difference between space and time.

At the moment of singularity, all physical properties and 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, 5.391 times 10^-44 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, photons were not born, and the radius of the universe at this moment was about 1 Planck length.
