Voyage of the Stars

Since the universe is very small at this moment, the quantum effect of gravity is extremely obvious, and is basically as strong as the other three forces, rather than becoming the weakest force as it is now.

At this moment, the four fundamental forces are indistinguishable from each other, so it is also called the super-force stage, which is the best cosmic environment for exploring the theory of everything. If you can be in this environment or create this environment in the laboratory, then the theory of everything can be easily derived just like humans discovered the laws of electromagnetic force and various physical laws.

The moment of grand unification is between 10^-43 seconds and 10^-36 seconds. At this time, gravity has been separated from the super-force, but the other three forces are still indistinguishable from each other.

The moment of gravity separation is the moment of the first phase change after the birth of the universe, and the symmetry breaking that leads to the generation of a positive matter universe or an antimatter universe occurs between these two moments.

Then the next is the period of 10^-332 seconds, when the universe undergoes the second phase change, and the strong force is separated from the grand unified force at this time.

This phase change manifested itself as inflation in the macroscopic universe. The inflation process lasted only 10^-33 seconds, but during this period the universe expanded 10^26 times.

The next stage after the big inflation was the quark and gluon period, which lasted from 10^-32 seconds to 10^-6 seconds. During this ultra-short period of time, the energy driving the inflation was released into space, so that the temperature before the space was heated again.

At this moment, a large number of elementary particles were formed, mainly a large number of quark and gluon plasmas, so it can also be called the quark soup period.

It was also during this period that various positive and negative particles were created in pairs and quickly annihilated, and there were also the appearance and return of tachyons.

The number of positive and negative particles in this period was equal until a certain moment later, about 10^-12 seconds later, because of some unknown reason, the weak interaction force separated from the electroweak unified force and became a short-range force. This is the third phase change of the universe, also known as the weak force symmetry breaking phase change.

At the same time, this is also the reason why the parity of weak interaction force is not conserved.

However, after understanding this, human civilization is even more troubled, because people think that they do not have the scientific and technological ability to do any Big Bang experiment. That ability is probably to master the theory of everything, and to master the theory of everything, this kind of creation experiment must be done.

It is a dead loop.

However, scientists are worthy of being scientists. They can always think of some feasible methods. They think that humans can find another way. If the Big Bang experiment cannot be done, they can start from temperature and entropy.

Temperature is a very special physical quantity. It has a minimum lower limit, that is, absolute zero, but no upper limit. But humans obviously have no way to create experiments in such an environment. Colliders will definitely not work, so scientists with this idea will focus on extreme celestial bodies.

That is a black hole.

Of course, it is not to run into a black hole, but to observe artificial black holes, understand the secrets of entropy, temperature, and time and space, and then derive the theory of everything from this. Their reason is that gravity is the most special of the four fundamental forces. It cannot even be called a force. Only gravity can create the most extreme celestial body, the black hole, in the universe.

According to the data obtained by humans from long-term observations of black holes, it is not the matter in space that is dragged to the singularity by the black hole, but also space-time itself. The other three fundamental forces all exist based on space-time. Therefore, the black hole that even drags space-time into the singularity must have dragged the basic intrinsic properties of the three forces into it, and then no one knows what happened inside, which turned into the three properties of angular momentum, mass, and charge.

Then humans only need to continuously use ion collisions to create micro black holes, and then continuously observe these micro black holes that evaporate instantly, and one day they will be able to observe the laws of the theory of everything.

It seems to make some sense, but it also seems far-fetched, and how can it be observed?

This has become a big problem facing scientists, because during this period of time, human scientists have tried, and traditional photon interference observation does not work, and neutrinos and tachyons do not work either. All the observation methods currently used by humans still cannot discover any new phenomena.

In this regard, some scientists think that the detection method is not good, and some scientists think that the observation method is wrong. At present, the scientific community of human civilization is still arguing about this issue, and there has been no conclusion.

However, such experimental research has been carried out.

Based on these views and arguments, there is also a group of older physicists who believe that humans should strive to find gravitons instead of doing creation experiments and collision experiments. They believe that they can first assume the existence of gravitons, and then build a new theory of gravity based on this. After that, they will find evidence of the existence of gravitons through observations of cosmic phenomena and various possible experiments, and thus find a theory of everything.

Another group of physicists believes that the unification of gravity should not be studied in this way, but gravity should not be regarded as a force, and the so-called theory of everything is not like the basic force that humans have unified in the past. It can be expressed by an equation, but should be a form of correlation.

Humans don't need to find any gravitons at all. They just need to regard gravity as a "basic force" that exists in a special form, or as space-time itself. In this way, they can start with tachyons. After all, tachyons have been confirmed to be a particle that is born in space-time and then returns to space-time itself.

And using this method to deduce, the final universal theory should be in the form of 3+1. That is, under the condition that the grand unified force field remains unchanged, the effect of the gravitational field is added to obtain a special super force field.

It also seems to make sense.

It is worth mentioning that this idea inspired another idea that is still in its infancy. That idea believes that humans do not have to stick to the research method based on the traditional theoretical research system, and can consider the problem from a different angle. That is: since we already know that the fifth-level civilization has the iconic energy utilization of negative energy, why not start with negative matter and follow the clues?

So how to follow the clues? Humans have no way to produce negative energy! This thing also requires mastering the universal theory, which is the same dead loop as before.

The answer given by these physicists to this question is to use the known properties of negative energy to find natural phenomena in the universe where negative energy may exist.

Well, it is still a phenomenon that exists in the natural world of the universe, isn't it the same as the previous black hole theory?

In general, human scientists have proposed various solutions and methods for a long time, but they all seem to be specious. They seem to be able to solve and seem feasible, but in fact, either the human technology level is not up to it, or we have to blindly search in the universe like looking for a needle in a haystack.
