The Origin of All

Any person questioned and interrogated for a few minutes to ask themselves how it happened the beginning of everything: The Origin.

On what was the origin of the super-sensible world, as would say dear good Aristotle, recalling his precise analysis on the unmoved mover.

What we have learned so far and rebuild is pretty much. We discovered that the universe expands: imagine that we have as a reference point two galaxies, pretty far apart. But still quite close, comparing their current position due to lower density.

The universe – as we know it – begins to refrigerate, and this primary condition allows atoms to take place in its subject, in its infinite textures, creating protons, neutrons and electrons to form atoms; not yet linked. But gravity do sense its presence.

Gravity starts to work in silence, with methodical precision for hundreds of millions of years after the Big Bang, moving the first hydrogen clouds that purchasing power will heat up and starting inside them nuclear fusion reactions that will ignite the stars.

The bis great-grandmothers of the stars of our knowledge, before becoming white dwarfs (though they were very sociable in the collapse along with other stars) and / or blacks holes imploding on itself, were formed by the unique elements then available: hydrogen and helium.

Since the helium burning will begin producing other elements, such as carbon and oxygen. And when finished helium, it drew nucleus by compression effected by gravity power to let other reactions take place: the burning carbon producing neon. Since neon is passed magnesium, and by magnesium to sodium in order to produce the twenty-six elements of the periodic table: including iron. The whole process arrived at this stage, and having its nucleus formed only by iron, the reactions were no longer able to continue beyond. The star became a super nova, collapsing cheerfully, and happy to release some of its elements to nearby stars, and in the adjoining space, allowing the formation of new stars.

At this point in our galaxy – the Milky Way – something very interesting was happening: a part of the larger cloud (as a cluster of planets and stars) had begun to supply workers to increase their density. The Milky Way seemed to play the willingness to envelop, and to take the form of disc, perhaps due to the whirling rotation of the atoms.

Millions of years pass, and the swelling of atoms compresses and heats up to become a star. Meanwhile in the disk where this star orbited we have to imagine tons of small grains of dust (a little clumsy) tended to collide with each other, forming then larger clumps.

They were sketches of current planets (in astronomical jargon the “planetesimals”) that in Milky Way‘s orbit managed to become giant balls of gas…Our wonderful Earth was one of them, and the gas once amassed created chemical compounds that allow us to be living matter, capable of transforming the energy through the body.

Every atom in our bodies originated from a star that is no more, starting by an explosion or by a change of elementary substances. To say that we are stardust, it is a quote goes beyond a marvelous poetic license, and the “sublime” attitude in science that drives beings to observe the particular into the universal.

This is a tangible truth, inherent in the chemical elements and physical forces that have made us capable of being as we are now. Indeed to be there, in the ‘here and now‘, as some familiar voice of contemporary “cultural landscape” would say:

All the matter we are made of was built by stars, all the elements from hydrogen to uranium have been made in nuclear reactions in supernovae, namely the stars much bigger than the Sun that at the end of their lives explode, and scatter into space the result of all nuclear reactions occurring within them. So we are truly children of the stars.
(Margherita Hack)

Every atom in your body came from a star that exploded. And the atoms in your left hand are probably from a different star from the corresponding one at your right hand. It is the most poetic thing I know of physics: you are stardust.
(Lawrence Maxwell Krauss)

We started to understand our origins, we are star stuff that meditates on the stars
(Carl Sagan)

Actually we are looking for the Origin of Life, to open ourselves to the universe and the universal presence of his own material in detail.
