Hundreds of years ago, after tens of thousands of years of development, human civilization finally entered the road of technological development. With the help of science and technology, mankind has also begun to explore the mysteries of all things and the nature of things. In the eyes of scientists, the universe is the ultimate goal of human exploration. Only when the mystery of the universe is revealed can human beings truly become the gods of the universe.
There are many mysteries of the universe, and the nature that interests scientists the most is the origin of the universe. Scientists have different views on the origin of the universe. In the 20th century, there were two main theories about the origin of the universe, one is the steady-state theory and the other is the big bang theory.
The so-called steady-state theory is that scientists believe that the universe is a static and stable environment, but with the continuous development of science and technology, scientists have discovered many mysteries about the universe, which are difficult to explain with the steady-state theory. Instead, the Big Bang theory can explain many cosmic mysteries, so in the end the Big Bang of the singularity became the mainstream theory of the origin of the universe in the scientific community.
Although we have no direct evidence to prove that the universe originated from the Big Bang, scientists have discovered through a large number of universe observations that many cosmic phenomena can be explained by the Big Bang theory, such as the phenomenon of universe expansion. Scientists have discovered through a large number of observations that the distance between galaxies is expanding, which means that the universe is expanding rapidly.
The theory of cosmic expansion can be said to be the most powerful support for the theory of the big bang, and now more and more people agree with the big bang theory of singularity. This theory tells us that the universe originated from the singularity big bang 13.8 billion years ago. A mysterious singularity gathered infinite energy, and then under strong pressure, the big bang occurred, and our universe was born.
If the universe came from the Big Bang of a singularity, then many people will have this question: How did this singularity come from? I believe that many people want to understand this. The singularity is described by modern science. It is an infinite mass and infinitely small energy collection.
Such a small thing gathers the energy of the entire universe. We all know that according to Einstein’s mass-energy equation, energy and matter can actually be transformed into each other. Before the universe was born, no matter existed, only this singularity, and when the singularity big bang occurred, super powerful energy was released instantly, and this energy began to continuously transform into various basic substances, and finally these basic substances Then it evolves step by step into everything in the universe.
In the early days, the temperature of the universe was very high, which should be above 10 billion degrees. Of course, the density of the universe at that time was also very high. But the universe at that time was relatively simple, with only a few basic tiny particles, such as neutrons, electrons, and neutrinos. As the universe continues to expand, the temperature also continues to drop. When the temperature of the universe drops, some chemical elements, such as hydrogen and helium, also appear.
Hydrogen and helium formed early stars, and stars refined hydrogen and helium through nuclear fusion to form various other elemental materials. After the stellar life reaches the end, a supernova explosion occurs, which is also a process of evolving elemental matter, and heavier elements appear in the supernova explosion.
With these rich elements and substances, the colorful space of the universe has been continuously formed. So where did this mysterious singularity in the singularity big bang come from? In fact, no one can give a definite answer to this. Nothing can be made out of nothing. This is the case in the universe and so is the singularity.
The universe comes from the big bang of a singularity, so this singularity must also have a place, and there may be a deeper cosmic mystery involved here. Someone once proposed the theory of cosmic reincarnation that the universe has a lifespan like stars. After the Big Bang, its expansion may not be infinite. When it expands to a certain extent, the universe begins to shrink. This is When the universe enters the countdown to life.
As the universe continues to collapse inward, the celestial bodies and matter of the universe will continue to collapse and re-transform into various elementary particles. As the universe continues to collapse, these elementary particles will return to their energy state again, and the temperature will get higher and higher. Finally, everything in the universe will be compressed into something that is as small as infinite. This thing is the singularity.
If the universe does have such a cycle, it means that our universe may be a continuation of the last universe, and the singularity is also condensed after the destruction of the last universe. As its volume continues to shrink, the pressure becomes greater and greater, and finally There will be another big explosion. In this way, a new universe was born, and a new round of cosmic reincarnation began.
In addition to this, there is another possible source of the singularity, which is man-made. Some people may say that when the singularity exists, our universe has not yet been born, how can anyone create a singularity? In fact, the man made by the editor does not refer to the advanced civilization of our universe, but refers to the advanced civilization from other universes.
I believe that many of my friends have heard of the theory of multiverse, which is also a conjecture put forward by scientists. Some scientists have speculated that the universe may be diverse. There is a broader and mysterious space outside our universe, and there are countless various universes in this space.
The birth time of different universes is naturally different. Some universes may have just been born late, and some universes may have been born millions of years, tens of millions of years. Those powerful civilizations in the ancient universe have scientific and technological strength far beyond our imagination. It is possible that they have already understood the nature of the universe and the ultimate mystery of the universe.
I believe many friends know that the power of science and technology is infinite. As long as science and technology are strong enough, it is not impossible to create all things, create life and even create the universe. It is possible that powerful civilizations in the ancient universe outside the universe have carried out a universe creation universe, created a singularity, and then detonated in the vast space outside the universe, thus giving birth to a new universe.
Although this conjecture is considered nonsense by many people, there is no permanent truth on the road of science. No one knows how powerful the technology will be when it reaches the end, and it may really be a role equivalent to the god of creation.
If the universe can really be created, then the origin of our universe needs us to rethink. Of course, these are too far away from us. For human beings, the first thing we must strive to achieve is interstellar civilization. Only with the ability of interstellar shuttle exploration can one hope to unravel the mystery of the universe step by step and finally understand what the universe is?
