Where is the divine locus
10
Nov
Of course the divine locus is anti-spatial and temporal, even modern
quantum physics developed the theory of the space-time dimension as the only dimension and where there are folds in time, but it is likely that physics will still make discoveries greater than wormholes. , accelerated space travel dimensions and will change our cosmic view of space.
The latest discoveries by James Webb, the telescope that looks at the origin of creation, already sees in what astronomers call the pillars of creation, the new images (10/19) show formations that look like rocks, but which are clouds of gas and dust of astronomical dimensions, where stars and celestial bodies are formed, in a kind of nursery.
The new image, using James Webb’s infrared resource [and it is possible to better observe the dust in this region of star formation (Image from NASA above), improving the image on the left of 2014 from the Hubble telescope, the image on the right being the image by James Webb.
In terms of the eschatological cosmovision, the one that studies the beginning and end of humanity, it is possible to imagine that through a “time warp”, we are still stuck in Einstein’s physics, this cloud forms and starts a development of stars, supernovae and galaxies in the universe.
The divine plan is even broader, since the time of Jesus, men wanted to know when the “kingdom of God” would be formed, an earthly dimension in which our human condition would be elevated to a level of happiness and prosperity that would reach everyone. , “where milk and honey flow”, but the master’s answer was not very pleasing to those who wanted something more tangible.
The reading in John 1:20-21 says they wanted to know the moment of this “kingdom” and Jesus replied: “the kingdom of God does not come ostensibly, nor can it be said ‘is here or ‘is there, because the kingdom of God is among you”, that is, it must take place among men, so there will still be many changes in the human and earthly dimension until this stage.
And the passage clearly says that before this the son of man (Jesus who is a presence of God among us said above), will have to be rejected and will suffer much.
Thus, it is necessary to find spaces of solidarity and fraternity among men where these seeds of full life are developed, men understand each other and look with love for their fellow man, without contempt or exclusion.
So this kingdom is near where there is love and brotherhood and far away where there is greed and exclusion.
Wisdom and Human Mistakes
28
Sep
Wisdom is not what makes man never err, but what makes it possible to
correct the route, change course and continue the process of true and human asceticism as a result of errors.
The great scientific theory of our time, both for Karl Popper and for Thomas Kuhn, two great philosophers of science, is the possibility that there will always be a course correction in scientific methods and theories so that man knows more about himself and nature that surrounds it.
Quantum physics, for example, has its beginnings in the enunciation of Heisenberg’s uncertainty principle, which stated that it was not possible to know exactly what the position of the particles of an atom was with exactitude, Planck who did not agree, it is his statement “I do not agree may God play dice”, went to the laboratory to prove this principle.
NASA (in the photo the crash of the spacecraft colliding with Dimorphos) has just made a scientific feat which is to hit a satellite of a small meteor, which does not pose any danger of collision with Earth, just to prove that it is possible to change course some celestial body, and with that, in case of danger to Earth, change its route.
The DART project is a test for a possible future mission to deflect an asteroid from colliding with Earth, for cosmic dimensions Dimorphos is small (160 m) and orbits another larger asteroid (780 m) called Didymos and form a binary system, the spacecraft that hit it was traveling at 22.015 km/h and the image seen from a telescope in Hawaii on Monday night (26/09, see below) shows that the impact produced many fragments, the deviation from the route, however, is small.
Changing route is wise, when you admit the mistake, but it requires two steps: admitting the mistake and then having the humility to change route.

The Einstein Ring and the Spheres
08
Sep
It was the philosopher Sloterdijk who was the first to create the
relationship between man and his spheres, from the maternal womb to the planet, he is largely right, also in criticizing cynical reason, the one that justifies spherical reality is largely correct, it is a metaphor, but very good.
Let us think of the fetus, which remains within the sphere of the uterus until it leaves and looks at its ex-sphere, the mother, will still feel her dependence for a long time, it happens that this sociological, anthropological, semiotic reality has its own topological properties that are hidden in the cynical reason.
One of them is to understand that there is an immunological relationship whose primary purpose is to protect, nourish, train and immunize homo from an unknown sapiens exterior, like the baby who at birth depends on the mother, he needs her immunological protection.
The search for other spaces, inhabiting the moon (the new mission finds it difficult) and mars (astronauts think it would be horrible to live there) does not resolve the planetary spherical relationship, in crisis, it is necessary to open up to the other and leave of the hut, some psychologists speculate about the hut syndrome, which the pandemic has accelerated, not wanting to leave a sheltered, spherical environment.
The super telescope James Webb photographs Einstein’s ring in a place far away and physically unreachable by man (the image), at least under current technological conditions, and the physicist’s prediction was “photographed” (actually the instruments are of frequencies and not of “photos”) with formidable precision, one can extend Sloterdijk’s metaphor.
Gerald’s 1916 theory of Gravity revolutionized physics by creating a physics that claimed that gravity is a curvature of the space-time continuum caused by the mass of objects, almost two massive objects were perfectly aligned with the Earth this space-time would deflect the photons forming rings around the alignment of these two objects.
An English physicist named Sir Oliver Lodge suggested that this phenomenon of a massive gravitational field would not only deflect light from an object behind it, but also magnify it forming a gravitational lens, and the recent James Webb photo confirms this phenomenon.
What is the metaphor, massive immunological spheres, cultures, religions or ideologies whose purpose is to protect themselves when close (or on a collision course which makes the metaphor more complicated) not only form a strong gravitational field that draws bodies around, they do not they only distort space-time, but they are also lenses that, if carefully observed, allow us to see what is behind.
So it is time to look beyond the differences, the imperfections of the spherological models and enable a gravitational attraction that helps to better understand the civilizing process.
Difference and identity in philosophy
11
Aug
The western philosophical system opposed difference and identity
in different fields, only Leibniz tried to create something different that he called the Law of Identity of indiscernibles, while Kant, in the face of the objectivity of his thought, will say that all objects are different even if there are similarities, because they are in different places.
Modern structuralists and poststructuralists make a distinct unification, claim that difference is constitutive of meaning as much of identity, more bluntly, identity (and also personal identity) is seen in non-essentialist terms as a construct, because they only produce meaning through the interaction of differences.
But neither structuralism nor poststructuralism adequately resolves this issue, Derridá coined the term “différance”, a deliberate misspelling of différence the correct word in French, as a conceptual hook on processes of meaning in writing/language, this device intended for an essentialist ontology critique, and for its Being.
The neologism différance is thus defined as “the non-original, constituting a disruption of presence”, creating spaces, ruptures and postponing the presence of the presence of Being in its totality, since the word differ in French is both to defer and to postpone.
Someone could be confused with the quantum lapse, what the physicist Nicolescu Barsarab, using a principle of the included middle of Stéphane Lupasco, space between two “quanta”, but it is necessary to remember that neither space nor time are absolute measures in quantum physics. .
Dualism is the basis of many modern authoritarian theories, all of them under the influence of Kantian idealism and, to a certain extent, Aristotelian philosophy, where being is and non-being is not.
It justifies the exclusion of a third term, of something that is different and similar at the same time, it is an opening to “fundamentalist”, “racist” and “scientist” philosophies, origin of Manichaeism present in modern culture, in quotation marks because there is true faith and science.
Thus, for the ontology of the included middle, being is, not being is not, and a being that is not and is at the same time, the included middle T is possible.
Pre-occupation and mystery
14
Jul
As we developed the themes of last week, the clearing is the abode
of the Being, in general and within certain contexts: “what is hidden within the whole, and from where the Being must emerge” that we elaborated there, this is what enchants the first images of the James Webb observatory, within the context of the universe, to look at great mysteries and phenomena there.
Leaving the occupation and entering the mystery is thus an expansion of the Being, when we discovered a new world at the end of the Middle Ages, a set of discoveries around science were also being illuminated and they too were the beginning of a clearing, but the close link to subjectivism, the path of a materialist objectivism had once again been hidden.
Pre-occupation, meaning what occupies our mind and, consequently, our act, develops in the whirlwind of modernity in a “society of Burnout”, where pre-occupation leads at the same time to mental and social exhaustion, and a lack of contemplation, that is, our inability to “admire and think about something” in a contemplative state.
Thus, it is only possible to leave pre-occupation through a process of clearing the Being, a plunge into the mystery, an ability to “put in parentheses” our thoughts and actions (the method of the phenomenological epoché), and thus return to “breathing” and leaving the toxicity of the modern world, we do not fail to analyze and observe the serious facts of contemporaneity.
Thus, the concealment, the mystification or false “mystification” of reality is opposite to the clearing, and very different from the occultism, the example of James Webb’s images and studies are a clear vision of this plunge into the mystery, where we can always find novelties and new enigmas. .
Pre-occupation is the sameness of the contemporary world, false problems and real problems hidden in discourses and addicted ways of seeing reality, like someone with vision difficulties and not subject to the use of glasses to clarify reality.
Contemplating is a complementary act with active life, and only it allows a unity of Being, where even in dark moments there is light and serenity.
James Webb’s First 5 Images
13
Jul
The first color images of James Webb have arrived, they
are really amazing and also the tools available to users, in addition to all the internal resources of course.
A historic target was Stephan’s Quintet, the first compact group of galaxies that was discovered in 1787, it is in the constellation of Pegasus, as the name implies, there are five galaxies, four of which dance between them and two are very close.
Birth in the so-called Southern Ring, an immense cloud of gas surrounding a dying star resulted from eight explosions from an ancient sun now reduced to a white dwarf.
An authentic “nursery” of a star, the white dots inside an enormous “mystical mountain” made by elements that “feed” the formation of a star, the so-called Carina nebula.
The other equally spectacular images were the first giant exoplanet, about half the size of Jupiter, of WASP-96 b, discovered in 2014 and which was shown using internal resources the spectrum of elements present on it, that is, if it has water and other chemical elements that make it up.
And finally a fifth image was shown of the cluster of galaxies, SMACS 0723, which works as if it were a cosmic magnifying glass to see and see what other galaxies are like and this is just the first.
Using an available zoom tool allows you to choose your target (in options above, for 5 images: JWST) and take the tour by traveling millions of light years and having an experience close to scientists.
Star Wars and James Webb’s First Images
12
Jul
Russia is developing an orbital station capable of destroying
satellites in orbit, it is a clear reference to Elon Musk’s StarLink send internet signals and other satellites that scour wartime images.
In November last year Russia successfully tested the destruction of its own inoperative spacecraft “Tselina-D” which had been in orbit since 1982, the missile was launched from the ground.
According to General David Thompson, deputy head of operations for the US Space Force, in a statement to the Washington Post, US satellites suffer attacks from China and Russia “every day”, so the war already extrapolates the planet, while ground wars are prolonged.
On the other hand, today is the day of the first photos observed by the James Webb telescope, at 11 am in Brazil, one of them will be the Carina nebula (photo taken by Hubble above), located 7,600 light-years away, where the objective is to understand the birth of the suns, which in this nebula are immense and in quantity.
On one side the birth and on the other the death of stars, another James Webb image will be of the Southern Ring nebula, an immense cloud of gas that surrounds a dying star and is about 2,000 light years from Earth.
A third target is historical, it is the Stephan’s Quintet, the first compact group of galaxies that was discovered in 1787, a period still with limited telescopes and that is in the constellation of Pegasus.
Using a special spectroscopy technique, which allows you to see the chemical composition of a distant object, a giant planet called WASP-96 b, discovered in 2014 and which is 1,150 light-years from our planet.
The fifth target, not necessarily in this order, will be the use of a cluster of galaxies, SMACS 0713, which works as if it were a cosmic magnifying glass and allows us to see other galaxies behind, and which will be the most fantastic experience for astronomers.
On the one hand, imprisoned and at war on our tiny planet with threats of war, and on the other, a look at infinity that should make us open our minds and souls to a new future.
There are forces that can change the course of catastrophe
27
Jan
The idea of some imminent catastrophe to happen is in the air, it’s
not just apocalyptics, but natural scientists who see planetary depletion (glaciers, species extinction, climate change, earthquakes, etc.), political scientists about the ideological tension that returns remembering the cold war, and it would be possible to avoid or at least have a positive reaction to it, the pandemic looks like it was a training and the rehearsal doesn’t look good.
One of the recent mysterious discoveries made by astronomers is that an object in our “galactic backyard”, which means at 4 thousand light years, a space object was found, as being a neutral star or white dwarf are only hypotheses, in which this object produces powerful beams of energy, the strange object (pictured) launches the beam of powerful energy that crosses the line of sight of the earth observed by astronomers and published in the journal Nature (see in ICRAR), are something unusual in space observations.
Natasha Hurley-Walker, from Curtin University’s International Center for Radio Astronomy Research, leads the team that made the discovery and stated: “This object was appearing and disappearing for hours in our observation…. It was kind of scary for an astronomer because there is nothing known in the sky that does that.”
There are also powerful forces that act in our midst, it is not just about cheap exploitations of prayers or positive feeling that can lead to the improvement of an environment and people, a set of words and actions taken in a positive direction for a given problem can and should able to resolve or change situations where the problem or conditions are great.
In addition to the pandemic, which some want to decree the end as if it were that simple, we have the tension of an imminent war, and we should have no doubt that all people who can speak, ask, meditate or pray that an atrocity of this size does not occur. they must do it, in war only civilians, the poor and the weakest who suffer, there is no palpable or healthy solution that comes from provoked catastrophes.
Mysterious object unlike anything astronomers have seen before – ICRAR
James Webb arrives at his destination
25
Jan
Exactly one month ago, the new James Webb Space Telescope
observatory (JWST Nasa) arrived yesterday at 17:00 (Brasília time) in a region where with a minimum of fuel consumption he will be able to remain in orbit, called the Lagrange L2 point, which is actually a region between the Earth and the Sun where the centripetal (attractive) force is balanced with a centrifugal force.
In fact, they are regions and therefore called orbital islands, every planet in the solar system has Lagrange Points and as they move away from the Sun these islands are larger, the island related to the earth is about 800,000 km wide, the which in spatial terms is small, the point L2 for example is 5 million km from Earth and still very far from Mars, 57.6 million is the distance from our neighboring planet.
The observations will still take 5 months to calibrate all equipment, adjust the mirror and aim for the first targets.
Now it will be 5 months of work for Webb to send the first images on his “targets in the infrared universe”, he will not look for exoplanets or new points, but point to known points and make measurements more precise and with greater definition, Webb’s mirrors ( hexagonal) that should have a complicated and fine adjustment will have up to 5 times the power of Hubble’s mirrors, in addition to using a more sophisticated technology that is infrared, where you can “see” by observing the light strongly “deflected to the red” of distant objects and can peer through clouds of murky dust, it will be able to sift through exoplanet atmospheres identifying gases with greater precision.
More than 1,000 teams of astronomers from around the world have requested time on the Webb in its first year and 287 have already been lucky enough to be pioneers, among the questions from these teams are looking at the ice-covered oceans on Uranus’ 27 moons, the icy giants Uranus. and Neptune can explain much of the origin of galactic systems, look at black holes that are of average size and resolve conflicting measurements on the rate of expansion of the universe and generally speaking will use Webb for two dominant themes: time and distance between opposite extremes in the universe. universe: the early universe and the closest planetary systems and their dilemmas.
In addition to these great themes, a topic that arouses curiosity, although it is due to a childish aspect of aliens, is what is called biosignature, that is, real conditions of life, which in fact do not find “beings” but the conditions of past or future existence. of them are: gaseous, direct or indirect products of the metabolism of living beings, of surface, of spectral results resulting from the radiation reflected by organisms, and, temporal, which are responses related to seasonal changes in the biosphere where there is, for example, diurnal and nocturnal variation of CO2, some biosignatures can be found, beings are still left to the imagination, it is clear that some biological form can exist in such an infinite space of probabilities.
Christmas gift
24
Dec
In December 1947, right around Christmas, three Bell Telephone
engineers (William Shockley, John Bardeen and Walter Brattain) invented the transistor (TRANsfer reSISTOR) that revolutionary communication and later computing, also ICs (Integrated Circuits) have as a base the transitor.
The big event this Christmas will be the launch of the James Webb Space Observatory (jwst, James Webb Space Telescope) from the Kourou space base, in French Guiana, at 9:20 am EDT, which will be taken to the Ariane 5 spacecraft. made at the cost of $10 billion, the most expensive space project in history.
What are we going to look for in space, in addition to other puzzles, the origin of the universe in its early stage, and it’s curious why this happens this Christmas, and why it is so special.
Lights decorate cities even in attention with a possible new wave of the pandemic and also a new flu, they light up hope and make us look to the future and to the beginning of our lives, our planet and humanity.
There is no way to escape from utopians, cosmogonies and religious eschatologies, even if we can solve many enigmas, the philosophical question remains: why there is everything and not nothing.
The answer can only be ontological, there is a reason for being and there is a promising future, where there is hope if we return to the logic of Being, of dialogue and of the encounter with the Other.
The message cannot be any other than that which speaks of brotherhood and peace, both not yet fully achieved by humanity, Christmas reopens this hope.
This is the prophecy that Isaiah announces (Is 52,7 when there will be true peace: “how beautiful they are, walking on the mountains, the feet of him who proclaim and preach peace, of him who proclaims good and preaches salvation, and says to Zion, ‘Reign thy God,’” the message that believed in the coming of the Savior, the birth among men of the Messiah.
The lights in the city not only announce this light visible to the eyes, but those that open the heart to friendship and peace (Jn 1:4-5): “in her was life, and life was the light of men. And the light shines in the darkness, and the darkness could not overcome it”, because a tiny point of light already dissipates the darkness, and this is our hope.
May Christmas renew hopes for a possible and sustainable future for humanity, and may justice and peace reign in a new world.
