Dispatches from the Birth of the Universe

 Dispatches from the Birth of the Universe

In fact, we know little about the universe in which we live, that we know more about the last episode of it than we do about the first episode.

Rather, we might not know if he had a first episode in the first place or not?

Imagine, dear reader, that the whole world is watching a series, and is waiting to know, will the hero live or die in the last episode, but we must know whether the hero is born or not?

Generally such questions have been and still baffle cosmologists.

The universe is made of a net

In the 1920s, the great scientist Albert Einstein, General Relativity Theory, this theory describes the universe made of a network, and it is this network that produces the phenomenon of gravity.

(Contrary to what is rumored, there is nothing that attracts anything else, the planet Earth is not what attracts us, but there is a network of spacetime that shrinks from being mass, and makes things fall on it)

This discovery was great, but I want you to imagine with me, if everything on the network has a mass, then the network will fall. In other words, if the universe is made of a network, it will begin to collapse on itself.

But if I told you that this idea did not like Einstein and began to think and think and then put what is called a cosmogical constant and put them in equations that support the universe and reflect that contraction of existence due to gravity, in fact then Einstein is one of his biggest mistakes, then he will discover that it is correct Discovering the dark energie.

The universe changed, not fixed

Russian physicist Alexander Freidmann and physicist georges lemaitre. They believed that equations that were of concern to the universe allowed a number of scenarios.

• The universe can shrink upon itself and get smaller
• It is also possible that if he was a beginner in the first of a fast expansion state, then if the universe grows even if the gravity is inverted, for example, when you want to throw a tennis ball upward, the gravity will bring it back down to your hand, but the more powerful the throw, the more gravity it takes so that You return it, and if you throw it fast enough as it falls for missiles and its throwing satellites it will win gravity and will not return to your hand, and so on ...

From the perspective of Freidmann and Lemaitre, the universe is always in a state of change, either it is expanding and expanding, or it is shrinking and reducing. But it cannot be stable.

So they see Einstein's theory that the universe is fixed. Wrong and unfounded.

studied the light coming from distant galaxies

Until Edwin Hubble and other astronomers studied the light coming from distant galaxies, when we disassemble that light into colors by analyzing the spectra, we find that the color very simply tends to red a lot, the meaning of these words is important and dangerous.

Especially since all colors were tending to red, and the idea here is that the color that we see is a wavelength of the eye for electromagnetic waves, the shorter the wavelength we find the light tends to blue and the longer the wave the more red.

Imagine, reader, if the light wave is leaders from a distant galaxy, if the universe is expanding and expanding, the wave will expand and extend on its way to us, until it reaches us, so it will be more red than the color it was launched with.

The further the wave is, the longer the wave takes on its way to us, and the more red it becomes and the more it expands.

So the relative equations that were. Correct without cosmogical constant and without any modifications.

So the dynamic universe is a variable that expands and expands throughout

Conclusion

In this article, I tried to explain whether the universe is fixed or variable with a simple explanation of gravity. Follow the second part in which I will explain how the universe began in detail.
