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 states that the universe was formed because of a big bang.
  1. What is the origin of matter?

To explain what the origin of matter is, it is necessary to go back to the currently accepted theories regarding the origin of the universe, since given the established laws of physics, the amount of matter and energy in the universe must be constant.

This theory about the origin of what exists is that of the so-called Big Bang ( The Great Explosion n ), and explains that the universe was originally a part A hyperconcentrated molecule that contained all the energy and matter that we know very densely accumulated.

This point was already tremendously unstable and 13, 798 million years ago there was a gigantic explosion that released a huge amount of heat (estimated at 1032 C) que and that the process began expanding, and therefore cooling, of the universe.

As the temperature decreased, the different known elements began to form, at the root of the subatomic particles we know: protons, neutrons and electrons, which began to combine to build volumes.

It is estimated that the first appeared around 3 minutes 20 seconds after the explosion, when the temperature of the universe had dropped to 1000 million degrees Celsius.

Initially, the only elements created were hydrogen and helium, the simplest known, in gigantic clouds of gas suspended in the emptiness. The atoms began to attract each other due to the gravity of their own mass, and increasingly dense clouds of gas were formed, whose weight and internal pressure began to rise, at such a point that its atomic nuclei began to fuse, releasing gigantic amounts of energy, just as it happened with the atomic bombs or inside the nuclear reactors, but at much larger scale. So the first stars were born.

Inside these stars, a massive nuclear reaction that emits a lot of light and a lot of heat was produced (already produced), and that by merging the atomic nuclei of the elements that constituted them, gives rise to new, more complex elements.

These stars were massive (between 3 and 16 times the size of the Sun), so their massive gravity was enough to force the atomic nuclei, increasing (and therefore with greater electrical charge), to merge despite of the repulsive forces that drive them away, generating more and more energy and heat.

That same gravity is what prevents the stars from dissipating in their own explosion, keeping together the material generated in a large ball of space fire.

Thus were born oxygen, nitrogen or carbon, and subsequently even heavier elements. Eventually there were so many that began to be organized in layers, the densest sinking into the star, giving rise to even more complex elements, almost reaching the total of the known elements.

Eventually these original stars fulfilled their life cycle and exploded in large supernovae, after burning all their fuel or reaching dangerous levels of matter that interrupted the cycle of nuclear reactions.

Then the elements enclosed in its interior spread at full speed through the universe, with a force such that many underwent changes and combinations along the way, thus giving rise to the heaviest and final elements of the periodic table.

These different elements, scattered throughout space, would eventually begin to gather and cool, combining with each other to form no longer new atoms, but complex molecules and chemicals.

These clusters of complex matter later would be planets, asteroids and all the astral bodies we know, including the planet Earth and also new, young suns, like ours.

This matter is also that which inside our planet would be combined in increasingly complex substances and eventually in chains of molecules that would start life itself .
