The discovery and the sound of pulsars

04 May

Supernovae are massive explosions of stars that until 1932 did not have many explanations, although they are observed and studied by astronomers.
Walter Brade and Fritz Zwicky sought the explanation when the subatomic particle called neutron was discovered so they understood that the answer was this, a neutron star.
It is a dense nucleus, as if two suns compressed in a space of the region of the great Sao Paulo of Brazil, but the explanation does not end there.
In 1967, the doctoral student Jocelyn Bell, captured in a radio astronomy equipment a weak pulse coming from a part of the sky with extreme precision, the house 1.3 seconds it repeated, it seemed an intentional signal of somebody or of and some civilization thought his counselor, but it was the discovery of pulsars.
Two important consequences of observation: to the extent that this star collapses its rotation increases greatly, and the other, is that collapse carries along with it the magnetic field forming a dense nucleus that spurs an energy beam dense to the space as pulses.
Russian scientists, capturing the flow of 10 pulsars, have created a song that along with other sounds of the universe form a great symphony of the creation and expansion of the universe.

Neither flat nor 3D, much beyond

26 Apr

The universe contains, from that sensible world to our senses, the world modeled by a three-dimensional geometry (length, width and height) other dimensions, the fourth dimension (hormholes, earthworm) is already reassessed by physics.
Time and space are more absolute and the energy and dark matter that makes up 94% of the universe begins to be studied with black holes (actually dark matter), but there is a lot of mystery.
What is certain is that our senses that built mathematics and physics up to the 19th century begin to be dismantled and gradually our senses are clearly challenged and among their ideal forms: point, straight, plane and cube are surpassed by the hypercube and the fractals.
Daring to Know, the idealistic formula constructed models of clearly idealistic universes, and does not correspond to the real universe, served for many advances and experiments, but there are mysteries that go beyond what the senses can perceive.
The fact that the image of an immense black hole was recently made, the sound of gravitational attraction was recorded proving that it exists as particles, gravitrons, shows that we have walked a little, but we must be wary of seeing, hearing and feeling. To look at infinity and its immensity, to admit that there is something beyond infinity, that the universe is not the mechanical machine assumed by Newton and formerly set in motion by the Copernican Revolution, are both now clearly seen as insufficient to explain the universe, and we are far from explaining it.
Excited theology and exoterism try to use quantum physics to explain the existence of God, to invent magical formulas for a more comfortable path to human existence, but there is life and death in our human lives.
Dead and life in animal and vegetable life, and in the whole universe, explaining it with images and sounds that allow our senses to believe is good, only that the mystery is even greater than the explanation.
In Christian eschatology, life beyond death, resurrection can be seen within this dynamic, after all even the apostles had difficulty understanding this, and Jesus appearing to they believe at him.
In the dialogue with Thomas, a disciple who did not believe Jesus says (John 20:27): “Put your finger here and look at my hands. Put out your hand and put it by my side, “and then concludes that those who believe without seeing are happy, have a vision beyond what is sensible, and can go to what is essential.

The sound of Gravitational attraction

25 Apr

The work was announced on February 11, 2016, confirming the theory of gravitational waves predicted by Einstein’s theory of relativity, where the LIGO Laboratory (laboratory of Gravitational wave Laser interferometer) along with the project Virgo, from the town of Cascina in Italy.

“We observe the first event in absolute which a collision does not produce observable data, except through gravitational waves. It lasted a fraction of a second, but the energy emerged was enormous, equivalent to three solar masses”, Ricci added.

The two holes formed a “couple”, that is, a binary system in which one orbited around the other, and they “had a mass of 29 to 36 times higher than the sun and approached an impressive speed near the light”.

“The closer they approached, the wider and more frequent the signal was, as an acute hum” said the scientist.

The work was published in the journal Physical Review Letters and was as impressive as the black hole recently photographed, with the difference that in the case of the black hole, in fact is a mass of dark matter, as we explained in another post.

But the phenomena are related because the origin of the phenomenon is in the collision of two holes (dark matter), which occurred a billion years ago, which made it present and doubly important the discovery, to explain gravity and black holes.

The video explains the phenomenon:



Shut me up, the stones will speak

12 Apr

It is not illusionism, pure utopia (Thomas Morus’s Utopia is the desire for a world with fairness), it is about understanding and respecting the mystery, of being aware that we do not know everything. It was not Einstein, but Heisenberg who first announced the quantum theory, which inspired Dali in his Mystical Manifesto, which changed the idea of ​​science, space, and time.

The image of the real black hole is just the tip of the iceberg of a mysterious universe, which surprises us and shows us our limitation.

Much of the contemporary regression is the incomprehension of cosmology and cosmogony, which in a different way are present in all cultures and religions.

Scientism, determinism, and materialism wanted to abolish the subjective thinking of cosmogonies, but it survived, and the discovery of the black hole is the enlargement of scientific cosmogony.

Says the biblical Reading (Lk 19:40) “if they shut me up, the stones will speak,” in the passage that the religious themselves asked Jesus not to speak of his eschatology, his mission and his end in the hands of the powerful. The quantum computation is explained by Shohini Ghose in 10 minutes:



The first image of the Black Hole

11 Apr

But in reality it is much more than that, and the proof of the theory of relativity, the variation of space and time (considered absolute in modernity), with the supermacious black hole photo, in the Center of The M87 Galaxy was unveiled on Wednesday at six simultaneous press conferences in Brussels, Washington, Santiago, Shanghai, Taipei and Tokyo.
It is the result of a decade of effort, made in five countries by the members of the EHT’s Collaboration of the Horizon of Events (EHT), and the imaging was done by telescopes connected to satellites in various parts of the earth see figure) to compose the image. But a black hole does not emit light, what was the photographer then-what does the image show at all? its shadow that it causes in its bright neighborhood, these rays of light in the surroundings deviated and distorted by its intense gravitational field form the reddish tones.
At its frontier happens a horizon of events, marking the points where even the light gets sucked out of gravity, is 2.5 times smaller than the shadow projects it, and yet measures 40 billion km from one side to the other, being this called Monster.
A 29-year-old scientist was important in the team of 30 researchers who helped compose the image, she is Katherine Bouman, a postdoctoral student at the Harvard-Smithsonian Center for Astrophysics and developed the algorithm for imaging.
The explanation of black holes is in video follow:


Good trip! Passengers to space

04 Mar

Elon Musk after revolutionizing the Tesla car, here in Lisbon I got in and I’m trying to test drive, after the revolutionary solar battery (do not adopt because of the electric and diesel trusts), now the first space travel with passenger was made. 
The SpaceX spacecraft, the first of a private project whose $ 250 million cost is a quarter of NASA’s cost, and has already docked at the orbital station on a quiet trip, still no passengers.
The tourist who paid part of the project is Yusaku Maezawa, a businessman who sold some in the mail and today has a clothing sales site called Zozotown, his identity was a long time in secret, Tesla’s BRF (Big Falcon Rocket) ship is reusable and was propelled by the Falcon 9 rocket, and should return to Earth in a week.
Maezawa’s project called DearMoon involves artist he enjoys and it’s a futuristic poetry without fail to have a business side.
SpaceX plans to reach Mars in 2022.
The details of the 8 tickets bought by Maezawa and her artistic dream are:



Line art, 3D and tesseract

19 Feb

The fact that contemporary culture is based on a science, an art and also an ethical and aesthetic dimension based on geometry has built an ideal model of nature, man and society, which is purely ideal and unrealizable to man.
It seems a post-humanism, since contemporary humanism is that of the Kantian categorical imperative: “Act as if the maxim of your action should become, through your will, a universal law”, sometimes the ” through his will, “but the imperious fact remains there, to become a model for others, narcissism and pre-humanism.
All this came from the idealism and absolutism of mathematical geometric ideas, it is not abstractionism since this current in both art and mathematics itself has in fact become much more revolutionary than it seems, the Hausdorff dimension and the fractals, as well as the mathematical and physical hypotheses about entropy prove this importance.
Physics in discovering the fourth dimension refers human thought and adventure to an unthinkable space, the intergalactic voyages, begins to draw the history of the universe itself, how supernovae form, what are black holes and black matter, finally a threshold of a new time, born of quantum physics and the fourth dimension.
What this has to do with art, with technology, absolutely everything, since the human vision and sensation widen, while many get into dogmatic holes, some even redeclarate the flat earth, the dimension of the infinite, the cosmogonies and the fourth dimension emerge
All this seems theoretical, but it was Carl Sagan in his famous Cosmos series, now available online, which explained all this in a simple and accessible way to all, follows a piece of your video in which explains this: 


Navigate deeper waters

08 Feb

Is a well-known expression in the Portuguese language “navigating is necessary”, but here the connotation of navigating deep waters refers to knowledge and spirituality.I think it should lead students to curiosity, interest in culture or human growth is stagnant, now in Web browsers too.
Navigating is necessary, said Portuguese navigators, but the phrase is more ancient, it was the Roman general Pompey, who encouraged fearful sailors with the phrase: “Navigare necesse, vivere non est necesse”, Petrarca in the fourteenth century who transformed in sailing is necessary, living is not necessary.
Fernando Pessoa, to whom some credit the phrase, actually said: “I want the spirit of this phrase for me”, and now we are in time to surf the Web (the internet is only the basis of this platform), but also to look at the confines of the universe and dream of journeys in the earthworm holes, which Einstein-Rosen predicted and astrophysics discovered.
This also means going to deeper seas, in the metaphorical sense, in knowledge, in the arts and in culture, the only consistent weapon against ignorance that passes militancy, not post-truth, I would say is a post-clearing, a phase of obscurantism.
Also in the spiritual sense, the biblical reading, for example, in the gospel of Luke, when sinners already washed their nets and were discouraged from fishing, Jesus encouraged them: Lk 5:4: “Go forth into deeper waters, and cast your nets to the fishing,” Pedro believes and does.
The correct reaction in times of retreats and apparent stagnation
The best attitude is not to stand still, this can lead to laziness and complacency, is to believe and to go forward, in this case a little faith is necessary.
True spirituality goes against the current of pessimism which is not only disbelief in God, but also in humanity.

The mystery and the spiritual

06 Feb

Both physics and mathematics have already surpassed not only the ideal dimensions: the point, the line, the plane, and the cube, by introducing the fractional dimensions which belong to the fractals immersed in the Hausdorff space, but also by the adoption of the fourth dimension.
The pioneering work was done by Charles H. Hinton (post) in A New Era of Thought (1888), previous to the quantum dimension of Werner Heisenberg and the discovery of the Worm Holes in which already imagine intergalactic trips like see in the fictional film Interstellar (2014),  and the film Contact (1997, of the book of Carl Sagan).
Hinton after having a dialogue with Kantian idealism will say about the human sensorial nature: “in the instinctive and sensorial perception of man and nature, everything is hidden, what reflection then brings to consciousness. We can be conscious a little higher than each individual man when we look at men. In some, this consciousness reaches an extreme point, and becomes a religious apprehension. “, That is, it admitted the spiritual aspect (post). 
It is in this dimension above the individual that Teilhard Chardin worked his noosphere, there may be a greater awareness when people work together, that is, obvious on the human plane, but not so obvious on the spiritual plane, it does not mean just being in agreement, but admitting a spiritual sphere, a noon (spirit) sphere, the noosphere.
As it is possible to penetrate this dimension, to make men work spiritually together, this is above prayer or spiritual meditation, in which one rises individually and even today for medical treatment is commendable, but a collective spiritual action.
The interesting thing is to note that both Chardin, who thought of a kind of cosmic consciousness, which was worth a departure from Catholic dogmas (he was a priest), but also the mathematician Charles Hinton seems to be moving towards the fourth dimension, Salvador Dali also spoke of this in his Mystic Manifesto (1951) and in conversations with the mathematician Thomas Banchoff.
Like Hinton’s philosophical discourse, Chardin’s philosophical anthropology in one of his seminal works “The Human Phenomenon” seems to address aspects of the same theme, a spirituality that leads to a larger collective consciousness and to feel the Universe as a body and as part of the Noosphere, approaching that which is substantial from that which is spiritual.
The reason that both Chardin and Hinton were discarded in their time is that they sought to penetrate a mystery, which Einstein also penetrated with physicist Rosen, wormholes are also called Einstein-Rosen Bridge (figure), being consistent with the theory of relativity.
What is beyond the physical, or the metaphysical is not always contradictory to it, but may be the solution to some of the mysteries of nature, 90% of the universe is mass or dark energy, little known, and recent discoveries are huge, see the Higgs particle (incorrectly called God) and black holes with several new discoveries.


A re-reading of the three wise men

04 Jan

In times of fundamentalism and religious intolerance, a re-reading of the Magi that they have adopted and also “contemplating” the birth of Jesus is essential for dialogue.
The first necessary is that God has communicated with the “wizards” of the East, he can reopen closed hearts for reconnection (religion of the Latin verb religare which is to reconnect), for they were not even religious in the conventional sense, but
magicians and God reconnected them.
The second is that the divine communication was through stars, which means that they could understand this language and that God spoke in their human language, that is, there are forms beyond the dogmatic communication between God and men, even non-believers.
Cosmology is an ancient and fundamental part of philosophy, its evolution and composition studies the universe, and comes from antiquity, the pre-Socratics studied it, also seek the explanation of the origin and transformation of nature and the universe and build myths and divinity, creating a relationship between mortal and imortal beings.
So God is not so indiferente to this, a universal proposition should not disregard cosmology, and if one wishes to construct a cosmogony, that is the beginning and end of all life, then an eschatology is also constructed, and Christian eschatology may be
related to Is not this, after all, God the beginning and the end of everything?
Thesecond re-reading, the question about of the stars, in fact even today they are looking for cosmological evidences of
the star that the Magi followed, a star, a comet, this could help to date Christmas of a more precise date.
Theologians such as Teilhard Chardin did not fail to consider the cosmological hypothesis, and the notion of a Christ-centered universe helps a non-fundamentalist interpretation of a more complex eschatology, and so we have recourse in the previous post to St. Gregory of Nazianzen.
The third is that the magi were “contemplating” the boy-God, in addition to the active vita, Hannah Arendt also spoke of her in The Human Condition (published in 1956, with Brazilian edition of 2009), which comes from the conference Work, Work and Action (Brazilian publication of 2006), but already spoke of this question Aristotle in the bios politikos and the vita negotiosa or actuosa in Augustine, and, recently Byung Chull Han in The society of the fatigue.
But they did not come to worship only, where the element offered incense is essentially this, but also brought gold in the sense of wealth and myrrh in the sense of sacrifices offered.
Magi should signify the opening of Christianity to other languages ​​which are also an expression of the infinite, of the universe, and of the sacredly constructed life in all and in all.
