The universe is vast, with countless stars, planets and other mysterious celestial bodies. When people walk out of the earth and see the vast universe, the first thing they think about is the origin of the universe. How did such a vast universe come from? Later, scientists put forward the big bang theory that the universe originated from a singularity big bang 13.8 billion years ago.
After the big bang, the expanding universe came into being. If the universe came from the big bang, what was it like before the big bang? Scientists have no definite answer to this question. It is far more complicated and mysterious than the origin of the universe.
However, when scientists observed and studied the cosmic microwave background radiation, they found stars older than the present universe. We need to know that our universe has a lifetime of only 13.8 billion years. If there are stars older than the universe, where do these stars come from? They can’t have been formed after the big bang.
Scientists are very excited after observing and discovering stars older than the universe, which may open a very important mystery about the universe, about what it might have looked like before the big bang. When scientists study the cosmic microwave background radiation, in addition to the discovery of ancient stars, they also find some huge residues which are completely inconsistent with the existing cosmic physics. Where do these residues come from?
Scientists are very excited about these discoveries, which brings us a step closer to revealing the truth of the universe. Scientists have a hunch that a new cognition will appear, which will overturn our existing view of the universe. In this regard, scientists put forward two possible new views of the universe.
The first view of the universe, that our universe is a cycle, infinite cycle. Just as there is a civilization cycle on the earth, human beings may be the intelligent life of the fifth era. Before human beings, there may have been other intelligent civilizations of four periods on the earth, but later these civilizations disappeared. This may be the civilization cycle.
The universe may and will not be immortal, it will not exist forever, but there is also a cycle. We all know that the universe has been expanding rapidly since the big bang. Will this expansion continue? Scientists believe that the expansion of the universe may not go on all the time. It also has a limit. When the expansion reaches the limit, the universe begins to collapse inward. Finally, the Big Bang will happen again, the old universe will be destroyed, and a new universe will be born.
According to this point of view, our universe is actually evolved from the last universe, such as white dwarfs, neutron stars and black holes evolved from the death of stars. When the last universe died, most of the celestial bodies and matter would be destroyed, but still some of them would enter the new universe with the big bang. The stars and remnants older than the age of the universe discovered by scientists may have originated from the last universe.
Different universes have different rules. The physical laws of the new universe may be quite different from those of the previous one. Therefore, scientists have discovered that there are substances in our existing universe that do not conform to the existing physics. They are the products of the previous universe.
The second is that the universe is not unique, but pluralistic. Scientists have long put forward the theory of multivariate cosmology. We believe that beyond our universe is a more vast space. There are many bubbles in this space. Our universe is only one of them.
Some scientists believe that the universe we live in may have had a violent collision with other universes in the early days. The collision between the two universes caused some matter from other universes to be impacted into our universe and preserved. Those ancient stars may have been squeezed into our universe when they collided with other universes.
If so, it can also explain why there are older stars in the universe. If the universe is pluralistic and has countless different universes, then the age of the universe is naturally different. Our universe is 13.8 billion years old, which may be just a universe of one age. In the world outside the universe, there may be many ancient universes that are far older than our universe.
In fact, the multi cosmology theory has been supported by more scientists. Now the scientific community has basically formed a consensus on the multi cosmos. Although it is still a conjecture, scientists have looked for some evidence in the universe. Ancient stars are only one aspect. If other universes have really collided with our universe, it will inevitably leave some problems As long as we find such traces, we can basically prove the correctness of the multiverse.
However, it is not easy to find such collision traces. Such traces probably only exist at the edge of the universe. If the universe really collided with other universes in the early days, most of the matter that other universes collided with our universe will also exist at the edge of the universe. The reason why scientists have been able to find some ancient stars may also be that they happen to have ancient stars on the edge of the universe and unexpectedly appear within the scope of human observable universe.
You know, stars are not fixed, there are also many stray stars in the universe. Moreover, when our universe collides in other universes, the movement and stillness must be quite large, and the energy generated is also enormous. After the stars of other universes collide with our universe, they may also produce huge kinetic energy. With huge energy, the lost stars will quickly move forward to the inner universe, and enter the universe that can be observed by human beings after a long time.
Of course, these are just some conjectures of scientists. What was it like before the big bang and whether the multiverse existed still need scientists’ continuous research and exploration in the future. To solve these mysteries, we need to one day be able to really observe the edge of the universe or reach the edge of the universe. Only when we can observe the edge of the universe, can we really uncover the mystery of the universe.
At the edge of the universe, there are early born celestial bodies. With the continuous expansion of the universe, they come to the edge of the universe. Only by standing on the edge of the universe can we really understand what the world outside the universe is like. One day, when we can go to the edge of the universe or even walk out of the universe, we may really see what our universe is like. It’s just like when human beings walk out of the earth, they know that the earth is a sphere and one of the countless planets in the universe.
It is possible that when we go out of the universe, we will also see countless celestial bodies floating in the world outside the universe, and these celestial bodies are all in the universe, our universe is just one of them, a dust in the world outside the universe.
