No one guess. Scientists have told what shape our universe has

The universe is really huge, but scientists have evidence of what shape it really is.

Due to the fact that it is difficult for a person to imagine the size of the Universe, which is actually infinite, it may seem that it does not have any form. But she still has a form, scientists say, although their findings may surprise, writes Live Science.

The most important indicators, such as the cosmic microwave background radiation left after the Big Bang, the expansion rate of the Universe in different places, etc. , how it “looks” from different angles, indicates that in fact the universe not only has no boundaries, but it is also flat.

Astrophysicist David Spergel of Princeton University, USA, has been studying the shape of the universe for many decades. He managed to find out that the cosmic background radiation, which remained after the Big Bang, has a non-uniform nature.

According to the scientist, the amount of positive and negative energy in a flat universe is exactly the same and, therefore, compensate each other. If the universe had curvature or bends, then one type of energy would be greater than the other, but this is not observed. Accordingly, CMB measurements have shown that the Universe is both infinite and flat at the same time.

“Although I admit that there are some uncertainties in the calculations, but if there is some curvature, then it is practically equal to zero,” says Spergel.

Another proof that the Universe is flat lies in the concept of critical density. For example, scientists from the Swinburne University of Technology, Australia, believe that if the universe is flat, then having a critical density, it would stop expanding only after an unimaginable amount of time. That is, there is a certain density limit that does not allow the Universe to be curved and take the form of a sphere. If it had such a shape, then under the influence of its gravity it would simply shrink to its original state or would disappear altogether. Such a theory, by the way, is called the “Big Crunch” and those who adhere to it believe that our Universe is waiting for just such an end.

But scientists, based on measurements, found out that our Universe has a density slightly below the critical value, which means that it is still flat, and besides, it will expand indefinitely. Also, some researchers have suggested that the evidence for the flatness of the universe is that it “looks” the same from any angle.

The results of other studies show that the universe is exactly flat, although the error in the calculations may be as low as 0.2 %. That is, within the limits of statistical error, our Universe is flat and limitless.

Focus already wrote about a new study in which scientists tried to test Albert Einstein's theory of relativity on the scale of the Universe. It turned out that there are some non-coinciding moments that are difficult to explain.

As Focus already wrote, in space there are objects and phenomena that can be deadly, both for the Earth and and for all mankind. Some of them can easily wipe our civilization off the face of the planet.
