"Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic fabric reveals deeper mysteries about existence, change, and the very nature of reality."(ScitechDaily, Does Space-Time Really Exist?)

Does spacetime exist? Does the space have time? We know the thing. Called material time. That time is seen in material evaporation. Because of the expansion of the universe. That thing causes an effect that all material turns into a wave movement. 

In the five-dimensional cosmological model, there are three spatial dimensions. And two dimensions in time.  Those two dimensions are time that goes forward and time that travels backward. In that model, time is one of the fundamental interactions. The idea in the spacetime model is that the Big Bang released material in time. Or it separated time and material. In this case. We talk about material evaporation. The model goes like this. The universe formed from a so-called Kugelblitz black hole. When the whirl started to collect energy in the proto-universe, it formed the black hole. Straight from that energy field that condensed into the black hole. When that black hole evaporated or detonated. That formed an event called the Big Bang. 

That means there is space formed between superstrings that will form the first particles. In that model, the superstring is an extremely thin energy field that turns into fermions and bosons. Superstrings are not single things. They are complicated internal structures. And in black holes, those superstrings are in such a tight form that they have no space to oscillate. That space caused an effect that those superstrings started to send sub-waves. When a superstring oscillates, it sends part of itself into its environment. This event would be similar to the material evaporation. 

When there is no energy that can resist the superstring, it sends the sub-string. In the same way as material, the existence, thickness, or number of structures in a superstring depends on the field that resists the superstring. The ten-dimensional superstring model explains the universe and space as an endless number of superstrings. The density or number of those superstrings in the space determines the strength of the field. When there are lots of strings in a small area, that means the field is strong. 

The main question in time dilation is this: Does that effect only push energy into particles? Or, does that affect cause a situation where the particle travels in time? 

Above: The 2D model of the gravity center. The gravity center packs energy fields around it. That forms a denser energy area. The gravity makes a pothole, but it also packs energy fields around the gravitational center. 

This denser, or higher energy area causes the effect that energy transfer to the environment slows down. And that slows material evaporation. If the difference between energy levels in the material and the environment is high. The energy level around the particle is very low. That raises the speed of energy flow out from the particle. The same effect can cause superstrings to decay just as matter. 

And that means the superstring model tells us that the spacetime should exist. When a gravity field forms, the gravity center rolls the field of those superstrings to the gravitational center. That effect is seen as a whirl in the universe. Those whirls can be extremely large. And all spiral galaxies are whirls that form around the supermassive black holes. Those whirls pull back, and without them, the black hole in the center of the galaxy will be detonated. 

And then we go to the spacetime. The idea in spacetime is this: energy fields or wave movement are everywhere. Those energy fields can condense into material. Because of the Schwinger effect. The Schwinger effect forms elementary particles, fermions. And bosons. In a similar way. The Schwinger effect explains the Kugelblitz black hole as a structure. Where the whirl will collect the energy fields or strings into one point. When there is enough field. Packed into one point. It creates a strong gravity effect that pulls everything into it. Without that whirl, the energy that is stored in a black hole is released. The whirl is the thing. That keeps the black hole in its form. 

We can think that when time moves from the past to the future, that thing looks a little bit like a superstring. When those time strings or “arrows of time”, or “time arrows” (Time’s arrow)move, they push time back around them. So when the arrow of time moves forward, that moves other arrows backward. If one of the arrows of time moves faster than the other arrow of time. That faster time arrow slows the slower arrows of time. The reason for that is that the time arrow moves energy into those other arrows of time. 

The arrow of time, along with Einstein’s Theory of Relativity, explains that when gravity turns so strong that the escape velocity turns higher than the speed of light. That means time starts to travel backward. The black holes will pump energy into the past if that model is right. And that energy is released at the point where a black hole forms. But the question is, does that thing really happen? Or does the black hole only store information and release it when it evaporates? This is the thing. That makes supernovae interesting. 

Theoretically, it is possible to decode the information that the black hole released. And there is a possibility. A black hole drives information straight into the point where. The black hole formed, and that point is the supernova explosion. Where the black hole got its beginning.

About scientific theories

  About scientific theories

All scientific theories that we have must be based on some kind of knowledge. Or they should be based on the best available knowledge. We get our knowledge using instruments like telescopes. And that is one of the things that makes science living. Our view of the world is changing all the time, because we get new and more effective instruments to do research. That means things like JWST telescopes bring new and fundamental views into our knowledge. And still, we are looking at precisely the same things that ancient philosophers researched and thought. We know more particles than ancient philosophers. But we still look for the ultimate part of materia. 

That part is the thing that we cannot decay. This is the thing in modern science. We find smaller and smaller structures, but we cannot find the ultimate part that cannot decay anymore. We can discuss things like God. And then we can see that those questions are too hard for people. Sometimes scientists don’t talk about religion because they are afraid of anger. But the other thing is this. Some people say that God is a member of a species that visited a long time ago. That means if a person believes in God, that person believes in other extraterrestrial civilizations. 

And those things are somehow very sensitive things in science. When we talk about the SETI program, we must realize that things like species on other planets were science fiction or pseudoscience a couple of decades ago. In the 1980s, people claimed that there were no other solar systems. And today we know many other solar systems. But we don’t know any other civilization. There was one promising exoplanet where there could be phosphine and methane in its atmosphere. But then the checks deleted those observations. 

The JWST telescope is the first instrument that can research exoplanets' atmospheres. The water planets can host lifeforms like primitive algae. But can there be intelligent and technically advanced lifeforms? The answer can be something that we don’t want to find out. Maybe primitive life is quite a common thing in the universe. But intelligent and technically advanced civilizations are less common. Nobody actually knows if there is some algae in the distant waterworld's oceans until we can fly to those exoplanets. Those algae don’t make any contact with other civilizations. But if we face another intelligent species from another solar system, there is always the possibility that the contact is hostile. 

And then we must remember the dark forest hypothesis. The universe is like a dark forest. We think that we are alone. We can yell and ask if there is somebody. But we cannot know what kind of thing is in the darkness. There can be some kind of bandit waiting for the right moment to strike. And that’s why we should think carefully, if we want to make contact with other civilizations that we don’t know. 

The thing is this. We don’t know anything about the aliens. We have many hypotheses. But those hypothesis bases are in our own culture. There are no officially confirmed alien contacts. That means all our “knowledge” of the other intelligent species is purely hypothetical, or its base is in imagination. And the imagination continues until we get in contact. 

Maybe that contact comes tomorrow, maybe after 1000 years. Maybe it will ever come. The problem is that nobody can predict when the contact will come. Or maybe someday in the distant future, when the Sun turns into a white dwarf, the human civilization moves to another solar system. In that case, our species turns into many other species. When the Sun uses its fuel, humans or our descendants must leave the solar system or face extinction. But those things happen in the distant future.
