Black holes and worldview

16 Jul

Until recently the material world comprised only the so-called baryonic matter which is 4% of the only one, which is the material that most people know, with the dark energy and mass appeared the “black holes” that are actually black bodies.
Scientists still believe from Einstein’s theory that black holes suck objects and everything around them, including light itself, now a new phenomenon can change that. This process of sucking is called accretion, so there is a hot plasma that orbits around the black hole and is sucked by accretion, but this can also occur in bodies, and now a body that resists this accretion has been sighted. of accretion body, by the junction of material around it in the process of protoplanet formation.
The GRS1915 + 105 object is actually two stars a black hole (the body whose gravity prevents anything from escaping, hence being called the hungry), and a very modest star for the proportion of the black hole, similar to the sun. If compared to the 13 billion light-years of the observable universe, it is close to the Earth, because it is 40 thousand light-years away, what intrigues is that the black star (the name looks better than a hole) is that the star -star is not sucked though called accretion.
Next to an American laboratory, the star was observed using an ESO (Southern European Observatory) telescope, forming a trio from Germany and Chile that captured the light from the companion star of the black hole and determined to ” technical “:
According to a paper published in Nature, astrophysicist Charles Bailyn of Yale University, USA, said that the calculations are still not very accurate in size, mass and energy: “It is computed using very simple observations and calculations based only on the laws of orbital motion of Kepler, who are already known and have been trusted for centuries. ”
The mass is one of the problem points, in addition to the aspect of the addition, according to Jochen Greiner of the Astrophysical Institute of Potsdam, Germany, one of the authors of the article: “I would be very surprised if the mass was so wrong that theories applied.
By that I mean that I am convinced that theories have missed the mark: “In fact it is already suspected that what we think about mass is something quite different, by the theory of the current relativity, until the particle of Highs and the existence of the black holes they seemed to confirm, since the universe copernican and newtonian were surpassed.
Now if the mass is the one that is measured, and the hole does not suck it, it means that there will be a new worldview, where mass and matter must be re-conceptued.


Earth-planetarism, a planetary worldview

09 Jul

We have already mentioned that the worldview depends on a vision of the cosmos and life itself, there is still a citizen worldview, Edgar Morin called the land-fatherland and what I call earth-planetaryism. Seeing the planet as Patria, as “common house” in the religious mystical vision, as Gaia in a mythological view, incorporate this view, for the planet itself, living beings including animals and plants and cultures that are the citizenship of living peoples in the Planet.

Broaden a cosmos-planetary view of the Earth they inhabit. In Edgar Morin’s book he traces in chapters 2 and 3 what this planetary identity would be, and at the same time reveals an exhaustion and planetary agony, there is something that involves beyond the traditions and cultural issues at stake, the worldview depends on how man sees himself as a whole, and this implies an advanced worldview, which admits the new telescopes, which made the Copernican revolution, which are now the new media.

Terraplanism is the most extreme side of this view, but attachment to an earlier view of quantum physics, black holes, the view of a multi-verse implies that the planetary cosmovision is still enlightened and idealistic, stuck to an idea of ​​citizenship , of state and of planet that already is much surpassed, and agonizes in successive crises. In the book by Morin and Anne Brigitte Kern, they point out that the key phenomenon to understand this crisis of planetary proportions is “moral, psychic and intellectual underdevelopment” (Morin and Kern, 2011, 115), including development, and the proliferation of holistic “hollow” ideals and of mutilated visions, the loss of the global, the fundamental and the responsibility “(ibid.).

Broadening this vision requires abandoning pseudo-planetary principles that are Eurocentrists, third-worldists, imperialists and neocolonizers present in the “saviors of the homeland” are left or right, generally unrelated and limited worldview.

A new planetary vision, which respects nature itself, demands a vision of an even wider universe that was thought by Copernicus, Galileo, Newton and the Enlightenment, the eternal dualism materialism x idealism, the imperial religiosity of some religions.

Lack of wisdom to the humble and humility to the wise, it is time to rethink the thought, as Edgar Morin wanted, a time of transdisciplinarity of multi-verse (several universes).

Spirit, World and unit

08 Jul

There is something in our consciousness that we can not define exactly what it is, a spirit, a mechanism of decision, a “vision of the world,” the certain thing is that what we call interiority has a deep layer that the philosophers of classical antiquity have called of “anima”, that which gives life, that animates and that is ultimately also a vision of the world.
Whether we like it or not, we have in the interior an “anima”, already the pre-Socratic philosopher Pythagoras (580-496 BC) believed in the metempsychosis that was the transmigration of the soul from one body to the other after death, and so in his worldview he believed in immortality of the soul.
Plutarch was also the author of “Consumption of the Flesh”, a theme that not only speaks of the soul, but initiates a separation between the body of the flesh and the immortal soul.
The theme is deepened by Plato in The Republic, his anima mundi (“soul of the world, from ancient Latin had another sense that was the” psyché tou pantós “), has the worldview of a shared soul or regent force of the universe by which the divine thought can manifest itself in laws that affect matter, so there is an immaterial force, which is at the same time inseparable from matter, which provides form and movement.
His doctrine was not endorsed by Aristotle, who in his work De anima, approaches more knowledge or active intellect, from which reflect from the Stoic and Neoplatonic schools, so the indirect link between Plotinus and Plato passes through Aristotle.
Plotinus will be a rare philosopher of antiquity attempting a non-dualistic concept of soul, the soul described in his work Eleades, part of the concept of the hypostasis that proceeds from the creative power, which is actually a third hypostase, a nous that generates the soul of the world.
Among the medieval thinkers who maintained the ideas of the anima mundi are Ficino, Pico dela Mirandola and Giordano Bruno with hermetic teachings, Cambridge pioneers, German vitalists Angelus Silesius, Goethe and Schelling, who had great influence on Bergson and through him Vladimir Vernadsky and Teilhard de Chardin.
Schelling wrote The Soul of the World (1798), although idealist influence guarded a worldview trying to unite organic and inorganic nature by connecting it to a continuum.

The noosphere here is the idea that a “soul-world” can cooperate with the contemporary world and a totalizing vision, the world view of the planet as a “common house” and that has a “soul-world” present and can not sustain a citizenship. Roger Scruton (75 years) is a contemporary author who tackles controversially the theme.

Cosmology, Worldview and Dialogue

04 Jul

The origin of the Greek word “kosmos” is linked to the idea of order, universe (or multiverse), beauty and harmony, also the cosmos through the position of the stars helped to organize the calendar in the origin of human history, cosmogonies and visions of the beginning and end of the uni- multiverse, of nature and of man.
The absence of a worldview also impoverishes the view of Being, Emanuel Lévinas examining the theme in his book Ethics and Infinity, a radical critique of the category of totality, typical of Western philosophy that led to the cult of Same and Neutral, absolute thought which led to tyrannies and totalizing ideologies.
In Aristotelian physics, previous to modern physics and unthinkable at that time an astrophysics of the multiverse, he elaborated a static model, of eternal flow of the becoming, submitted to an order, the Copernican revolution put everything in motion, and modern astrophysics recovered the model of “Infinite”, where matter and dark energy dominate 96% of the universe.
The cosmogonies are fundamental to understand the formation of cultures and religious thoughts of diverse peoples, legends and myths can usually be thought around a metaphysics, and the beliefs that make them possible as an explanation of the world.
The worldview is present in any form of thought, so materialism, idealism and spiritualism are cosmovisions, as a partial apprehension of the totality and the solution and encounter of the Other are made in function of this worldview.
Thus, in a dialogue of cultures, imperative for a globalizing world and the demand of a global citizenship although not recognized, it is necessary clarifications of this cosmovision, of way totalizing and while admits the infinite like mystery and becoming.
We find in the Basic Dictionary of Philosophy (Jupiassu, Marcondes, 2008) that cosmology supposes the possibility of a knowledge of the world as a system and as an expression of a discourse, the postulate of a totalization of the world, if made by knowledge, of an eventual cosmology of knowledge itself.

Uni-verse or multi-verse

03 Jul

It is not a joke with verses and poetry, we have already seen and posited that the universe is made up of frequencies that in the last instance is music, that the first energy released by the universe were frequencies that are ultimately light, now there is a new enigma and there is more than one universe, a multiverse.
Three aspects may lead to the idea of the multiverse, two are already widely studied: the idea of cosmology that comes from the Greeks and today comes the deepest subtleties of matter and dark energy, called black holes that was enlarged with the idea of inflation, second the string theory that of simple hypothesis began to be studied and verified, and the third (or first in the historical sense, began with Hubble in 1929), the idea that the universe (the multiverse we know) is expanding then one day this united, the Big Bang.
The idea of an expanding non-expanding universe led to the second point of string theory, the mathematical-physical model suggests that the fundamental blocks are not points or particles, but strings that vibrate in a kind of cosmic symphony, emerging from music that these strings can play, however with small mathematical inconsistencies. It is these inconsistencies that create the need for a fourth nonlinear dimension such as we know (height, width and depth), but a micro-dimension that delimit how these “strings” can vibrate, the analogy with music is perfect because we only hear in a delimited frequency band, and they vibrate in a delimited range.
It is in this delimited range that is the black energy, it together with black matter composes 96% of the universe, what we know as “matter” is matter and barium energy, only 4%.
The forms present in string theory (photo) can be numerous and even infinite. The question remains if one day observation could make the vision of the multiverse possible, just as in 1964 the scientists Arno Penzias and Robert Wilson captured the background radiation that came from all directions of the cosmos were the proof of the Big Bang Theory.
Scientist Brian Greene explains that the theory of cosmic inflation may someday prove the existence of the Multiverse and explains how the evidence of this theory is already present in quantum theory and in the observation of dark energy.

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:
