The universe is expanding in another dimension?
The entire Universe as we know it is in a bubble and expanding in another extra dimension, according to researchers at Uppsala University. A concept proposed by the researchers could help solve the dark energy puzzle.
We have known for several decades now that the Universe is expanding at an accelerating rate. Researchers believe that a mysterious cosmic force is responsible, ktora acts in opposition to gravity – dark energy. Understanding the nature of this force is one of the greatest puzzles wspomodern physics.
Part theoristow believed that the mystery would be explained by string theory. According to it, all matter is composed of tiny, vibrating, string-like objectsow. All particles are one-dimensional chains, ktorych vibrations determine properties such as mass and charge.
The theory assumes roalso the existence of more dimensionsoin spatial dimensions than the three we have known since elementary school, and how these additional dimensions are configured determines the characteristics of the Universe, whichory we perceive. These extra dimensions are inaccessible and elude our experience, so we cannot observe them. String theory also allows for the existence of many unique universesow, w ktorym our particular is only a small part of a larger whole.
For a long time, string theory was a majorown candidate for the theory of everything, whichora in spojny wayob would describe all physical phenomena, whichore we observe. Over the years, more and more new models of string theory have appeared, whichore would take into account and explain the mystery of dark energy. However, according to someoers researchers, none of the models proposed so far are true.
Proposed by scientistow from Uppsala University the solution may helpoc explain the mystery of dark energy. The concept of the Swedish researchers assumes that our Universe is in a bubble, or rather at the edge of this bubble, whichora expands into another, additional dimension. Going further, all the matter we observe is made up of endsowek strings, ktore extend along this extra dimension.
In other words, we are living within the confines of one of many expanding bubbles, and dark energy is being induced in subtle waysob by the interaction between the walls of these bubbles and other dimensions of the. Big Bang, in whichohe birth of our Universe is when our bubble began to expand. Matter in our reality is endowkami strings extending into extra dimensions.
– It is increasingly clear that the models proposed so far in string theory to describe dark energy suffer from a problemoin math – said Ulf Danielsson of Uppsala University, wspopublication router. The basic problem, according to the researcher, is that the rowations governing string theory mobinds that any universe with our version of dark energy should quickly disintegrate and disappear.
Scientist modelow from Uppsala provides a new and different picture of the origin and future fate of our Universe. Could pave the way for methods to test string theory.
