Will the universe expand forever?
(ORDO NEWS) — The most popular hypothesis is that the universe was born in the Big Bang about 13.81 billion years ago. Space-time began its rapid expansion in all directions, and this process continues to this day.
There are billions of galaxies in outer space, among which our Milky Way “hid” too.
How did the evolution of the Universe to its observable state take place, and what can happen in the distant future?
In search of answers, a team of astrophysicists at Stanford University, led by Risa Wexler, ran computer simulations.
Modern technologies make it possible to trace how matter could form and how it influenced the Universe.
By grouping calculations and computer simulations, Wexler’s team observed a huge number of options for the formation of matter, matter and how all this gave a chance to appear massive structures in the young expanding Universe.
“When we observe the most distant galaxies, we peer so far into the past that we can predict the behavior of dark matter and dark energy, which influenced the further distribution of galaxies in the Universe at different time intervals.
Over the past decade, we have made significant progress in creating the latest cosmological model that will allow us to describe the properties of space-time.
It is likely that when we finish the work, our views on the world will seriously change,” Riza Veksler commented on the ongoing work.
The existence of dark matter and dark energy no longer arouses surprise and serious disagreement among scientists, since the evidence is generally plentiful.
The best way to observe dark matter activity is in the dwarf satellite galaxies of the Milky Way.
It is there that the gravitational forces of stars are very small and the behavior of the luminaries can be explained only by the influence of something very powerful or by something that is very much (dark matter and dark energy together make up about 95% of the entire matter of the Universe).
According to astrophysicists, it is dark energy that “inflates” the Universe from the first fraction of a second after its birth. The model created by the Wexler team demonstrates the infinite expansion of space-time.
Distances between galaxies will increase, connections between them will be lost, but the Universe will continue to generously “produce” new stars and galaxies.
Wexler’s team is convinced that our universe does not really have a “shelf life” and the processes observed today will continue over and over again.
The only question that remains unanswered for researchers is the rate of expansion of the Universe, which is constantly increasing.
It is likely that acceleration is a constant or variable property of space-time, but further research should answer this question as well.
Is it possible that the universe, having received a beginning, will never find its end?
