The structure of the universe - good
Galaxies take on characteristics of streetlamps cluttering up neighborhoods of dark matter , linked by highways of gas that run along the shores of intergalactic nothingness. This map of the Universe was preordained, laid out in the tiniest of shivers of quantum physics moments after the Big Bang launched into an expansion of space and time some Yet exactly what those fluctuations were, and how they set in motion the physics that would see atoms pool into the massive cosmic structures we see today is still far from clear. A new mathematical analysis of the moments after a period called the inflationary epoch reveals that some kind of structure might have existed even within the seething quantum furnace that filled the infant Universe, and it could help us better understand its layout today. The scale of this kind of modelling is a little mind-blowing. We're talking about masses of up to 20 kilograms squeezed into a space barely meters across, at a time when the Universe was just seconds old. The oldest light we can still see flickering through the Universe is the Cosmic Background Radiation CMB , and the entire show had already been on the road for around , years by then. But within that faint echo of ancient radiation there are some clues on what was going on. the structure of the universe.Becau e if the univer e i finite, then it Content: In cosmology, there is still no clear answer to the question that affects the age, shape and size of the Universe, and there the structure of the universe also no consensus about its finiteness. Because if the universe is finite, then it must either contract or expand. In the event that it is infinite, many assumptions lose their meaning. Back inastronomer J. Shezo was the first to doubt that the universe is infinite: after all, if the number of stars has no boundaries, then why does the sky not sparkle and why is it dark? InG. Albes argued the existence of the boundaries of the Universe by the fact that the light coming to the Earth from distant stars should become weaker due to absorption by matter that is on their way.
But in this case, this substance itself should heat up and glow no worse than any star.

This assumption has found its confirmation in modern science, which claims that the vacuum is "nothing", but at the same time it has real physical properties. Of course, the absorption of photon energy by a vacuum leads to an increase in its temperature, which results in the fact that the vacuum becomes the structure of the universe secondary source of radiation.
Therefore, if the dimensions of the Universe are really infinite, then the light of stars that have reached the limiting distance has such a strong redshift that it begins to merge with the background secondary radiation of the vacuum.
At the same time, we can say that the dimensions of the Universe observed by mankind are finite, since the speed of light itself is also finite. The distance of 24 Gigaparsex is the boundary of the light cosmic horizon. However, due to the fact that the rate of expansion of the Universe is increasing, the end of the Universe is at a distance of 93 billion light years.
The most important result of cosmology was the fact that the universe was expanding. It was derived from redshift observations and then quantified according to Univerde law. This led scientists to conclude that the Big Bang theory is being confirmed. However, this result is possible only if it is assumed that the model underlying the analysis is correct. When using other estimation methods, completely different data are obtained.

Touching upon the structure of the Universe, one cannot but say about its form. So far, no three-dimensional figure has been found that would best represent its image. This complexity is due to the fact that it is still not known exactly whether the Universe is flat.
The second aspect is connected with the fact that it is not known for certain about unniverse multiple connections. Accordingly, if the dimensions of the Universe are spatially limited, then when moving in a straight line and in any direction, you can be at the starting point. As we can see, technological progress has not yet reached the level to accurately answer questions regarding the age, structure and size of the Universe. Until now, many theories in cosmology have not been confirmed, but have not been refuted either.]
You are not right. I am assured. Let's discuss it. Write to me in PM, we will communicate.
Completely I share your opinion. I like your idea. I suggest to take out for the general discussion.
