La vie c'est la resurection a l'envers

 

When I go from hence
let this be my parting word,
that what I have seen is unsurpassable.

I have tasted of the hidden honey of this lotus
that expands on the ocean of light,
and thus am I blessed
---let this be my parting word.

In this playhouse of infinite forms
I have had my play
and here have I caught sight of him that is formless.

My whole body and my limbs
have thrilled with his touch who is beyond touch;
and if the end comes here, let it come
---let this be my parting word."


Rabindranath Tagore

Summary:
Position: Profesor Titular en la Universidad de Guanajuato

Fields of interest:

  • Exobiology - Because intelligence increases with the extension of our actions on reality, the next step in the evolution of life passes by the conquest of space.
  • Starburst galaxies and AGNs - Consequnces of the formation and evolution of galaxies.

  • Cosmology and the formation of large scale structures:
    Unfortunately, not an advice followed today. Rashid Sunyaev: “...we should use well known physics to understand the Universe”; excerpt from Sunyaev dicourse of acceptation of the 2003 Cosmology Prize, pronounced during the opening ceremony of the 25th General assembly of the IAU.

  • The role of entropy in the formation of structures by gravitational collapse
    “If someone points out to you that your pet theory of the Universe is in disagreement with Maxwell's equations - then so much the worse for Maxwell's equations. If it is found to be contradicted by observation - well these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can offer you no hope; there is nothing for it but to collapse in deepest humiliation.”
    Sir Arthur Eddington 1929

  • The meaning of physics - a new way how to understand mathematics and physics
    In the “Feynman Lecture on Physics”, Feynman said: “if, in some cataclysm all of science knowledge were to be destroyed, and only one sentence pass on to the next generation, the statement that would contain the most information in the fewest words would be: all things is made of atoms.” However, a more complete statement would be: Matter is made of particles, and spacetime is the product of their interactions.


Ongoing research:

As Sherlock Holmes could have said:“It is easier to find something if you know what you are looking for.” (in Silver Blaze, 1892, by Conan Doyle). Below you will find a brief summary of the different working hypotheses that are guiding my research.

  • Compact groups of galaxies (CGs): CGs are the bricks from which large scale structures form; the power law of the primordial density fluctuations must have been steep (very few large structures formed), and it is flattening with time due to the dissipation of energy (and production of entropy) produced by the formation of these structures.

  • Starburst galaxies and AGN:
    -- Relation with galaxy formation:
    galaxies are the results of the cosmological process of structure formation by gravity; The Universe is young, and most field galaxies today (at low redshift) are still in construction, building a bulge and growing a supermassive black hole (SMBH) at their center.
    -- Starburst and AGN are two sides of the same process:
    the formation of a galaxy is a thermodynamical irreversible process, dominated by the formation of a SMBH at its center; tell me what SMBH grows at the center of a galaxy and I will tell you what kind of galaxy it is.

    -- Narrow-line radio galaxies vs. broad line quasars: evidence of hierarchical biased galaxy formation
    -- Low Luminosity AGN are evolving, dying QSO.

  • Cosmology:
    --
    The irreversibility principle: the formation of structures by gravitational collapse is equivalent to a thermodynamical irreversible process; the formatiojn of BH is an irreversible process, and its entropy is the entropy of entanglement of matter falling onto the BH.
    -- Connection between entanglement and non-causality:
    the BH horizon is a non-causal structures, similarly the Big Bang is a non-causal structure, then it must have been in entangelment. If entanglement implies thermalisation, then this may be one alternative to inflation. OPne can test this idea in a laboratory
    .

  • Exobiology: a definition of life based on interactions and entropy - a diagnostic diagram for exoplanets

  • Epistemology - expelling metaphysics out of physics and mathematics: A theoretical framework for physics based on the genetic epistemolology of Jean Piaget: Intelligence is the integration of the action of the subject on the object.

    Below I show a model of how intelligence works, based on Piaget's epistemology (the diagram was adapted from the definition of the role of technology developed by Lucio Russo in his book: The Forgotten Revolution: How Science Was Born in 300 BC and Why it Had to Be Reborn, 2004, Springer)


    Our knowledge of reality is not direct, because we know it only by interacting with it (action of the subject on the object). Reality (object) is not arbitrary (physical laws are not arbitrary), because the results of our actions on reality are not arbitraries. Our brain constructs (integration process) an image of reality which takes the form of a set of psychomotor patterns (ideas and concepts are patterns of actions). Logic and mathematics are the abstract forms that the connections between these psychomotor patterns take in the brain: through a trial-error process the best connections (most successful actions) are selected and consolidated. These connections allow to expand our range of possible actions on reality;knowledge = expansion of our range of actions on reality.


    As a consequence, space and time are not separated objects, but one abstract form in our brain, spacetime, outgrowing from our interactions with reality. Therefore, one can explain physics purely in terms of interactions (fundamentally, interactions between "particles", or, more objectively, events), revealing its true meaning.

    The goal of intelligence is survival, not the metaphysic quest of determining what is reality. Knowledge is an adaptation process.The duty of scientists in our society (which is unfortunately not recognized, even by those who produce science) is for them to give the most adequate description of reality, identifying the most efficient actions, in order to improve our living conditions and our chances of survival. This goal includes not just humanity, but all life on Earth, because there is only one form of life on our planet; Intelligence is universel.
