origin of matter
We explain everything about the origin of matter, the currently accepted theories and its process until the formation of life.
The Big Bang establishes that the universe was formed by a great explosion.
What is the origin of matter?
To explain the origin of matter, it is necessary to go back to the currently accepted theories regarding the origin of matter.universe, since given the laws of the physical, the amount of matter Y Energy in the universe it must be constant.
This theory about the origin of what exists is called "big Bang”(The Big Bang), and explains that the universe was originally a hyper-concentrated particle that contained all the energy and matter that we know very densely accumulated.
This point was in itself tremendously unstable and 13.798 million years ago a gigantic explosion occurred there, releasing an enormous amount of heat (which is estimated at 1032 ° C) and that started the process of expansion and, therefore, the cooling of the universe.
It is estimated that the first appeared around 3 minutes 20 seconds after the explosion, when the temperature of the universe had dropped to 1 billion degrees Celsius.
Initially, the only elements created were hydrogen and helium, the simplest known elements, in gigantic clouds of gas suspended in a vacuum. The atoms began to attract each other due to the gravity of its own mass and increasingly dense clouds of gas formed whose weight Y Pressure The internal nucleus began to rise to the point where their atomic nuclei began to fuse, releasing gigantic amounts of energy, as happened with atomic bombs or inside nuclear reactors, but on a much larger scale. This is how the first stars.
Inside the stars there was (and still is) a massive nuclear reaction that emits much light and a lot of heat, and that by fusing the atomic nuclei of the elements that constituted them, it gives rise to new, more complex elements.
These stars were massive (between 3 and 16 times the size of Sun), so that its enormous gravity was enough to force the atomic nuclei, each time larger (and therefore with a greater electrical charge), to merge despite the repulsive forces that push them away, generating more and more energy. And heat.
That same gravity is what prevents the stars from dissipating in their own explosion, holding together the material generated in a great ball of space fire.
Thus were born oxygen, nitrogen or carbon and, later, even heavier elements. Eventually there were so many that they began to be organized in layers, the densest ones sinking towards the interior of the star, giving rise to even more complex elements, almost reaching the total of the known elements.
Eventually these original stars completed their life cycle and exploded into large supernovae, after burning all their fuel or reaching levels of matter that interrupted the cycle of nuclear reactions.
Then the elements enclosed in its interior scattered at full speed throughout the universe, with such a force that many underwent changes and combinations along the way, thus giving rise to the heaviest and final elements of the universe. periodic table.
These different elements, scattered throughout space, would eventually begin to come together and cool, combining with each other to form no longer new atoms, but molecules and complex chemicals.
