The conversation, which is a science media, published a very interesting article by physicist Neil Turok on October 24, this article is titled “cosmic inflation, the primitive cosmos expanded in size, a mirror universe that goes back in time may be an explanation simpler", because of course this cosmic inflation is a headache for scientists and Neil Turok and his colleague what they proposed is that there is a mirror universe where all those things prohibited in ours would exist and that would go, time would go backwards, but other things would also go contrary to what happens in our time and in this way we could square the mathematical problems and problems that give or what we are seeing what we are observing about the expansion of the universe and inflation as well as other problems.
According to Turok, the dominant theoretical approach to explain the current universe is the combination of String theory with a powerful mathematical framework and that at the moment works quite well, adding the issue of cosmic infringement, it helps us for the moment, we know that there are little problems , there are things that are squeaky, but at the moment it is the best we have to explain what we are seeing and it is to explain how the universe works.
In combination, string theory and inflation predict that the cosmos will be incredibly complex on tiny scales and completely chaotic on very large scales, the nature of the expected complexity could thus take a bewildering variety of forms and despite the absence of evidence, many theorists promote the idea of the existence of a multiverse, we have no evidence but there are theories about the possible existence of a Cosmos, understood as a Cosmos as an uncontrolled and unpredictable ocean where a multitude of bubbles of universes would be, each with completely different physical properties and laws different.
Some would be uninhabitable, they would be radiation soups, others may have physical laws more appropriate for life and if there were beings there they would be practically like gods compared to us, but so far observations indicate exactly the opposite; What should we do with this discrepancy, one possibility that these two researchers point out is to simplify the universe.
Simplify the universe and reduce the range of scales that we can explore today or put another way we see what we can see, but there is much more that we cannot grasp and when observations and experiments reach small enough scales in the subatomic world or large enough in the cosmic world because these researchers believe that the supposed complexity of the universe will begin to reveal itself.
Another possibility is that the universe is really very simple and predictable on both the largest and smallest scales. I wish it could be like that, it must be like that, there must be something that we still haven't finished fine-tuning, according to string theory. basic components of the universe are tiny vibrating loops and pieces of subatomic strings, and it is a theory that works at least it explains quite well what we know about the universe, this does not mean that it is the definitive theory but for now it works quite well.
As understood, this theory only works if there are more dimensions of space than the three we experience, so string theory theorists assume that the reason we don't see more dimensions is because they are tiny and coiled up. , supposedly when the big bang began those dimensions did not unwind and remained in the subatomic world, unfortunately this makes the String theory very difficult to prove, because we reached as far as our observation teams go and verify those dimensions rolled up is very complicated because they are on a very small scale.
