What is the universe made of and what is its origin?
30
May
Greek philosophers from the 6th century BC
believed that the four elements of all nature were: fire, earth, water and air, Pythagoras proposed a practically religious school that everything was numbers while Democritus proposed the atom and that they would have rounded, smooth, irregular shapes and smooth, being able to form an infinity of elements, but until the end of the Middle Ages it was believed that fire was composed of one of these particles: the firegist, we owe the chemical table to Dimitri Mendelev who in 1869 organized his chemical elements, previously the alchemist Henning Brad discovered that phosphorus heated with urine residue caused flames and Antoine Lavoisier in 1789 organized some elements into simple, metallic, non-metallic and non-metallic.
Current standard physics has established 7 elements: neutrinos, electron, quarks, photon, graviton, gluon and weak force boson, but there is a more mysterious quantum world that of superstrings, it seems frightening or using the physicists’ word ghostly (Einstein used it the first time realizing that there is a third state in quantum physics in which the element is neither nor is it, later called the Included Third).
The most convincing theory of the universe until recently was that of the Big Bang and an expanding universe, entropy, Stephen Hawking was its great theorist, although this theory already existed before, and thus proposed an “arrow of time” in his most important book. famous “A brief history of time” (1988), but James Webb’s discoveries called into question when he found galaxies and celestial bodies at the edge of the universe that shouldn’t be there, now even the arrow of time is questioned.
The important thing when looking at the universe is to understand where everything came from and whether this whole thing and intelligent life, which for now we only find on our planet Earth, had a beginning and more importantly, had an intention.
The biblical “fiat lux” seems to agree so much with the Big Bang theory, before atoms there were waves or “strings” created in the first 10−44 seconds (Planck time) and then subatomic elements were created, in the case of strings, everything It is initially formed by one-dimensional strings that would be divided into “open” strings (linear) and “closed” strings (in loop strength), vibrating at different frequencies that would give rise not only to the 7 elements, but also the molecules that initiate life.
Be that as it may, there was an initial moment, and the form of this “being” must have been preceded by a creative “being”, the paleontologist and Christian theologian Teilhard Chardin proposed that the entire universe would be the body of this supreme “Being” of the “being”, thus he should have a divine and a material (human) reality, thus he proposed that the universe is Christocentric.
It is not possible for the All to have emerged from nothing, and if there is an original form of the All, of some “element” the physical world is composed, thus there is a “Corpus” of this All, with the difference that He is the creator and all the rest created, but created with some substrate of its own Supreme Being, of course the theory for this is more elaborate, but its understanding is simple, we are part of a body, of a group that communicates, the idea of the individuation of the universe is not plausible, because at the beginning we were one thing: a small cosmic corpuscle, a set of vibrating strings (we could even think of a choir making a song), but there was a moment of creation. and Someone created it.
The information paradox in the cosmos
14
Mar
The issue of information with black holes is that
any object that falls there and you will never see it or have any information about what happened, even the merger of two black holes is impossible to undo, you cannot separate them and what happens?
Black holes just don’t seem to preserve any information.
Throughout the history of science, our scientific laws were written based on quantifiable observations, this information is certain measurable physical properties of matter and energy. A molecule or particle, such as a proton or an electron, for example, contains a mass value, an electric charge, a spin and several other quantum properties (number of baryons, leptons, hypercharges, etc.).
However, there was the famous Higgs or “God” particle, something that attributed mass to others and an experiment at the Large Particle Collider (hadrons) managed to detect it, in a black hole that absorbs a certain amount of particles, matter and energy throughout of time, itself is made up of particles with unique properties, and so it should contain a significant amount of information, but where is it?
The right question is where did this amount of information go? In theory, a black hole made from the collapse of a normal star, where the emerging black hole can be observed, has completely different encoded information than a black hole made from the collapse of an antimatter star (considering it possible), for example.
This is not a violation of Newtonian physical laws, but rather quantum theory itself, because when Stephen Hawking applied the rules of quantum mechanics to black holes he discovered (or supposed) that isolated systems would emit a form of radiation, called radiation. Hawking, which would be independent of the initial state of the black hole and would depend only on its mass, electric charge and angular momentum.
If information is not preserved or evaporates entirely through Hawking radiation, there is a paradox: among the most accepted hypotheses currently is string theory, the main candidate for a new unified theory of nature, which accepts that information really escapes from a black hole.
So if you jump into a black hole, you won’t necessarily be gone forever; Instead, information from your body may emerge, particle by particle, to reconstitute you in some way from these small waves, called “strings”.
Observations from the James Webb super space laboratory and continuous studies into the frontiers of thought will take us even further, towards the confines and enigmas of the Cosmos.
Globalism or Universalism, a new period
05
Jan
The current crisis clearly points to a civilizational
crisis, Eurocentric and Enlightenment visions already showed their exhaustion in previous periods, by thinkers such as Nietzsche and Shopenhauer who sought elements in Western philosophy, but quantum physics and studies on an era called “anthropocene ” such as the transdisciplinary studies of Anna Tsing, founder of AURA (Arhus University Research on the Anthropocene) and one of the editors of the Feral Atlas (feralatlas.org) published by Stanford University Press.
Thus, the theories of globalism and NWO (New World Order) are nothing more than conspiracy theories, although the political forces at play may also have influences from various political organizations that desire new forms of imperialism and population control.
Simply looking at an increasingly complex universe in which old Copernican and Newtonian paradigms, of great influence on Western thought, die, show a much more complex reality, such as string theory pointed out by Michio Kaku as one of the few alternatives to explain the universe as we now see it through megatelescopes.
Even Einstein’s idea of understanding the mind of God is very far from what a theory of Everything and the Whole really means, where it is almost impossible not to think of a Being with an unimaginable intelligence who created everything, a simple energy or chance is simplistic Too many and even theoretical physicists such as Albert Einstein, Stephen Hawking and Michio Kaku have admitted this hypothesis.
However, it is difficult to imagine a mega-intelligent consciousness in the face of such primary reasoning that involves the majority of Christian thinkers, figures such as Augustine of Hippo, Thomas Aquinas, Duns Scottus and Boethius, these last two are considered saints by Catholics, seem to be overshadowed by a fundamentalist primarism that ignores the complex universe we live in and which still reveals itself to be incomprehensible within human limits.
For serious religious people, it would be enough to examine the visit of the wise (see youtube) men (people from other beliefs and cultures) who came to worship the newborn in Bethlehem to become aware that God is universal and is not limited to human dictates and customs, but there is a lot of false prophecy.
The limit of a true Christianity should be as Augustine of Hippo said: “the limit of Love is to love without limits”, this should be essential to a true God of Love.

The mystery of black holes
04
Jan
The center of the Milky Way, the galaxy where our
solar system inhabits, is formed by a disk with spiral arms and a dense, yellowish central region known as the “bulge” and there are around ten billion stars orbiting the colossal object that is its center called the supermassive black hole Sagittrius A*.
So, if in the past geocentrism (the Earth as the center) was a naive idea, now Heliocentrism (the sun as the center) is also a provincial and outdated idea, but what black holes are, it was not Einstein but Karl Schwarzschild who was the first to propose its existence.
Steven S. Gubser’s book “The Little Book of Black Holes”, deals in a simple way, as much as possible, explains Einstein’s special and general relativity and Schwarzschild’s equations that gave rise to the topic, black holes are one of the strong themes in current astronomy and one of the sources of research for the James Webb mega-telescope.
The book begins by recounting an experiment carried out on September 14, 2015, almost a hundred years after Einstein announced his theory of general relativity, two massive detectors, one in Louisiana and the other in Washington, were carrying out a gravitational wave experiment when they detected an audible signal, such as a serious knock and five months later they announced that they had detected two colliding black holes forming a larger one, the discovery was spectacular.
Both black holes and gravitational waves were predicted in Einstein’s Theory. In this theory, the black hole is a region of space-time (the notion of absolute time and space has already been overcome) where all nearby matter is attracted and is impossible to escape.
There is a popular saying that everything that goes up must come down, says the author, however the idea of the Schwarzschild equations is that nothing can go up, only come down and in the case of black holes where does that which must come down go, that is, what happens to what is attracted to the black hole.
We know the story of the apple that would have inspired Newton’s law of universal gravitation, the author of the book then suggests an apple falling into a black hole.
An apple outside the black hole events everything is static, at the horizon of these events everything is dynamic, flowing towards an all-encompassing singularity (where space-time changes dynamically in an extraordinary way, there two dimensions compress and the third is stretched.
Stephen Hawking, famous for proposing Big Bang equations, speculated that black holes are not actually black, they have their color (in fact, outside our visual range of colors from violet to red) determined by temperature, energy and entropy of its surface (if we can call the two dimensions that, since it is space-time).
This simplified introduction is developed over seven chapters of the book, in astronomical details and their equations, which requires some more specific knowledge of physics.

Physics and the mind of God
03
Jan
The basic original question of man is language,
but when searching for information man was forced to look at the universe and try to understand its enigmas, geocentrism (the earth as the center of everything), heliocentrism (the sun as the center of everything) dominated human language and thought for millennia, throughout this time anthropocentrism dominated human conception and with this the attempt to dominate all of nature grew.
However, nature is indomitable, modernity was an attempt to dominate the forces of nature and assert anthropocentrism over it, but it has its own logic, and when looking more deeply the universe that had a mythological explanation moved to a more focused focus. clear of eschatological inquiry: where did we come from and where are we going.
The book by theoretical physicist Michio Kaku: “The God equation” takes a deep dive into this issue from contemporary physics and cosmology, the physicist is the great theorist of string physics (Hyperspace is one of his books), professor at Harvard and host of programs on Discovery Channel.
In his book he explains the quest of physicists such as Stephen Hawking and Albert Einstein to try to explain all the forces of the cosmos, what is called the theory of everything, and which in its current formulation is called the Standard Physics Theory, the discovery of quantum forces of particles, including the Higgs boson, the vision of the photon with a particle of zero mass, the particles of terrestrial magnetism helped this unification, but that’s not all.
Many physicists have failed, the quantum explanation breaks with the idea of “thing” that some dualist authors continue to have, the “quantum” is something beyond it has a third state, called in physics the “third included” where a particle is between the Being and Non-Being and is not dual.
If this state of quantum physics is already a reality, what the particles actually are is still a mystery, and the “most promising candidate (and, in my opinion, the only candidate) is string theory, which says that the universe it is not made of point particles, but rather of tiny vibrating strings, where each mode of vibration corresponds to a subatomic particle” (Kaku, 2022).
We would need a microscope powerful enough to see electrons, quarks, neutrinos, etc. they are nothing more than vibrations of tiny loops, similar to rubber bands. If we put these elastic bands to vibrate countless times and in different ways, we will eventually be able to create all the subatomic particles in the universe, and this means that the laws of physics are summarized in these modes of vibration of the small strings.
Kaku says in the introduction to his book: “chemistry is a set of melodies that we can play with them. The universe is a symphony. The mind of God, which Einstein eloquently referred to, is a cosmic music that spreads across space-time” (Kaku, 2022).

Chardin’s universal vision
28
Dec
For a certain time, Chardin’s vision of a universe
formed from a divine intention, its evolution within a geosphere, then a biosphere and finally the current stage that is a noosphere (noon – spirit) was considered heretical, but at the time few were changing, many philosophers and theologians began to study him, his works were being published and acceptance by the church was being considered, to the point of even thinking about his beatification.
One can think in the current controversies, without serious doctrinal meaning in my opinion, that this is due to a certain heretical “modernization” of the church, but the most diverse theological thoughts within the church reflect on the validity of this vision that updates Christian thinking and gives a great opening to what modern man has discovered and continues to discover about human life on earth and the cosmos.
In a homily by Pope Benedict XVI, on July 24, 2009, in a homily in Aosta, Benedict XVI quotes Teilhard de Chardin, as a positive illumination: «The function of the priesthood is to consecrate the world so that it becomes a living host, so that the world becomes liturgy: that liturgy does not pass by the reality of the world, but that the world itself becomes a living host, becomes liturgy. This is the great vision that was later also that of Teilhard de Chardin: in the end, we will have a true cosmic liturgy in which the cosmos becomes a living host.”
And this is not a new doctrine, although Chardin brought it closer to Science, the Second Vatican Council in the Constitution Gaudium et Spes (nº 5), in fact, declares: «In short, the human race passes from a basically static notion of the order of things to a more dynamic and evolutionary conception: this gives rise to a huge new problem that requires new analyzes and new syntheses.”
And in the Catechism of the Catholic Church (n. 310), we read: «God freely wanted to create a world “in a state of progress” towards its ultimate perfection and Jesus will come in his glory, after wars, pestilences and other civilizational difficulties, to save him, says eschatology.
Thus, not only does original sin, the expulsion from paradise and the human future open up to a new perspective consistent with the doctrine, but it also clarifies controversial points historically, we would say due to the Copernican revolution, man and the world are neither geocentric nor heliocentric, at the center of the galaxy is a black hole, so we could say that it is noocentric,

Terrestrial identity and the black hole
01
Nov
Chapter 2 of Edgar Morin’s book is “The
Terrestrial Identity Card” where he states that after the discoveries of astrophysics, biology, paleontology, ideas about the life of the universe, the nature of the Earth and man’s own life were “subverted in the 1950s-1970s” and we still didn’t have James Webb and the discovery of the ties between homo sapiens and Neanderthals.
“Afterwards, with Copernicus, Kepler, Galileo, the Earth stopped being the center of the universe and became a round planet around the Sun, like the other planets” (page 43) and seemed to “witness the perfection of its divine creator” for order and regularity, until an expanding universe was discovered based on Hubble’s observations of the separation of stars in 1923, the astrophysicist would later give his name to the famous telescope already surpassed by James Web.
At the beginning of the 19th century, “Laplace expelled the Creator God from a self-sufficient universe that had become a perfect machine for all eternity” (pg. 44) and not cited there, but also in a Mathematics Conference at the beginning of the 19th century. . XX Hilbert proposes some last problems not solved by mathematics, to say that everything is logical and mathematical.
In 1965, Arno Penzias and Harold Wilson would give facts for this expansion of the universe as an “isotropic radiation originating from all horizons of the universe” and this “cosmological background noise” a kind of “fossil residue” from the initial deflagration of the initial explosion that would confirm the famous Big Bang theory, today the new data casts doubt on this, but something remained from this period, which is the conception of anti-matter and the investigation of black holes.
The 1960s, when Penzias and Wilson won a Nobel Prize, would bring new celestial bodies among them: “quasars (1963), pulsars (1968) (pg. 44), then black holes, and astrophysicists’ calculations suggest that we only know 10% of the matter, 90% of which is still invisible to our detection instruments” and that James Web is only now looking at.
The center of our galaxy is no longer the sun, but a black hole, and in it unfolds a whole new vision of the universe as “in its beginning the Unknown, the Unfathomable and the Inconceivable” (pg. 44), here we are now in a galaxy 8 billion years after “the birth of the world, and which, with its neighbors, seems attracted to a huge invisible mass called the “great Attractor” “ (idem), which is a black hole.
And we, a small planet, created 4 billion years ago, discover that it has a history, “and takes shape in the 19th century” and on the threshold of the 20th century, the German Alfred Wegener elaborates the theory of continental drift, despite the initial resistance, proven later.
After its initial long periods of cooling, the formation of the first microorganisms, and finally man appears, “the last and deviant branch of the tree of life, appears within the biosphere, which, linking ecosystems to ecosystems, now involves the entire planet”, This early birth, in recent discovery also unites Neanderthals and homo sapiens.
If “Bacon, Descartes, Buffon, Marx make it their mission to dominate nature and reign over the universe” (pg. 54), “from Rousseau onwards, romanticism will umbilically link the human being to Mother Nature” and thus, having a mother, man can be born and inhabit this Mother Earth.

Eclipses of the civilizing process
13
Oct
Harmony between peoples, acceptance and
tolerance of differences, dialogue and diplomacy on conflicting issues seem to be further away than ever, like an annular eclipse, it obscures the light and lets only a ring of fire pass through, and as they are There are several points of light sources, there are also regions of shadows that will be confused, looking like night.
Various research shows that this happens to birds when faced with an eclipse, they see that it is getting dark and they behave as they do at dusk, they reduce their activities, withdraw and almost go to sleep, as the eclipse is quick, then they return to normal activities.
These are civilizing processes, there are periods of darkness and it seems like it could be an endless night, but after this moment seeing the mistake of “sleep” during the twilight, they rediscover life and return to normal activities, in the human case with a new perspective of Peace and tolerance, of course, always leave terrible marks: innocent deaths, destruction and misery.
We could have prepared a party, a concert and harmony between peoples, there was no shortage of educators, prophets and futurists who tried to design this scenario, but men always have free will, in our case, we can choose between the eclipse and the twilight and the day.
Eclipse because whether by natural forces or by divine intervention, those who believe desire and wait for this day, even if millions of innocent people perish, the desire for the triumph of good, common sense and peace among men is always an irreversible path, even if they suffer.
There is a biblical parable that depicts this scenario well, a man was preparing a party and as the guests did not come (they chose other paths), he sent for men on the street, but among them there was also one with inappropriate attire (anti-party attitudes) and asked to be removed, says the reading (Matthew 22, 10-12):
“Then the servants went out into the paths and gathered together everyone they found, both bad and good. And the party room was full of guests. When the king entered to see his guests, he noticed a man who was not wearing a party attire and asked him: ‘Friend, how did you come in here without your party attire?’ “.
“Then the servants went out into the paths and gathered together everyone they found, both bad and good. And the party room was full of guests. When the king entered to see his guests, he noticed a man who was not wearing a party attire and asked him: ‘Friend, how did you come in here without your party attire?’ .
The civilizing process is like this, whoever will win a conflict situation, everyone will lose and in the end those who were on the margins of the conflict process will prepare a new path

Eclipse, shadow and twilight
12
Oct
We have seen historical and mystical aspects of
the annular Eclipse, now let us focus only on the phenomenon.
The Eclipse is a natural phenomenon that occurs when a body is within a region of shadow caused by another body that has enough light to reduce the luminosity. In the case of a solar eclipse, the Sun is the luminous star and the Moon is positioned between the Sun and Earth, producing a shadow on Earth.
For the Moon to cast a shadow on the Earth, it must be in the New Moon phase, which is when it is between the Sun and the Earth and has a slight semi-arc on one of its edges.
To better understand how eclipses occur, we need to know the concepts of shadow and twilight.
A shadow is when from a point source of light (that is, its dimensions can be neglected as if it were a single point) it is projected onto a smaller intermediate object that will produce a shadow on the larger object, this shadow can also be called an umbra.
In the penumbra there is an extensive source of light, which must be taken into account when the light source is very large or is close to the object, in the case of the Sun it is large enough to produce, from the light on the Moon, a shadow and a penumbra over the Earth (figure).
Thus, the rays of light do not come from a single point, due to the size of the Sun, but from several points, so there will be a region in which it produces a shadow, but others with partial lighting that produce some shades of twilight.
In the figure, the shield disk is the Moon and the larger disk is the Earth. For educational purposes, only one region of shadow was produced, but they are diverse and weaken as they move away from the shadow region.
The phenomenon of the lunar eclipse next Saturday (10/14) is special because an arc around the Sun becomes visible and is therefore called an Annular Eclipse (in the form of a ring).
Eclipse, the Theory of Relativity and town Sobral
11
Oct
In addition to mystical and historical factors,
the eclipse helped the development of both physics and astronomy, there is a curious relationship between an eclipse, the Theory of Relativity and the Brazilian city in the State of Ceará: Sobral.
On May 29, 1919, the sky over the city of Sobral, a city in the interior of State Ceará, Brazil, dawned cloudy (photo taken by the National Observatory in 1919) and the effort of the delegation of astronomers who went there to observe the eclipse and prove their ideas Albert Einstein’s revolutionary ideas would be in vain.
Fortunately, at nine o’clock in the morning a space opened between the clouds and it was possible to make the desired observations.
Einstein’s ideas were that there would be a distortion in the space-time dimensions and that this would be linked to the proximity of massive bodies, stated as follows:
“The trajectory of light can be distorted if there is a massive body distorting space-time in its trajectory, so it appears that the source that emitted that light is in a different position.”
With sensitive equipment, it was possible to make this comparison in the positions during the eclipse and after it, which occurred in May 1919. In December, after months of studying the observations, it was announced that Einstein’s theory was correct, and this is a fact which made the theory of absolute space and time obsolete.
The observation took place thanks to intense collaboration between Brazil and England, including the famous English astronomer Arthur Eddington, from the Royal Astronomical Society and the Brazilian Henrique Morize, then director of the National Observatory (ON), and Sobral was chosen because it had better visibility. of the eclipse.
One hundred years after the event, in 2019 the Brazil-United Kingdom partnership in Science and Innovation was celebrated, Brazilian physicist Anelise Pacheco, director of MAST (Brazilian Astronomical and Sciences Related Museum) declared at the time: “Without cooperation, there is no science”, this also applies to the days of today.
