General Relativity defines gravity like the metric of a Lorentzian manifold. Einstein formulated spacetime as quality structural of gravity, i.e, circular definition between gravity and spacetime, also Einstein denoted "Space and time are modes by which we think, not conditions under which we live" and “We denote everything but the gravitational field as matter”, therefore, spacetime is nothing and gravity in first approximation an effect of coordinates, and definitely a geometric effect. The mathematical model generates quantitative predictions coincident in high (...) grade with observations without physical meaning. Philosophy intervened: in Substantivalism, spacetime exists in itself while in Relationalism as metrical relations. But, it does not know what spacetime. The outcomes of model have supported during a century, validity of the General Relativity, interpreted arbitrarily. Einstein formulated, from quadrupoles of energy, the formation of ripples in spacetime propagating as gravitational waves abandoned, in 1938, when he said that they do not exist. LIGO announced the first detection of gravitational waves from a pair of merging black holes. They truly are waves of quantum vacuum. (shrink)

Desde la formulación geométrica de la gravedad, según la ecuaciones de Einstein-Grosmann-Hilbert, de noviembre de 1915, como el movimiento geodésico en la variedad semirimenniana de curvatura positiva, espaciotiempo, donde por ausencias de simetrías, no es posible la conservación de la energía-impulso tomando en conjunto los procesos materiales y el del campo geométrico gravitacional, sin embargo, dadas esas simetrías en el espaciotiempo plano de Minkowski, usando el modelo de De Sitter, Einstein linealizando la gravitación, por supuesto, realmente en ausencia de gravedad, (...) en 1916, depuradas de algunos errores matemáticos en 1918, introdujó las "ondas gravitacionales" como perturbaciones en la curvatura del espacio, y en ausencia de saber físicamente qué es el espaciotiempo y filosoficamente en pleito, que previamente en 1936 y definitivamente en 1937, Einstein demostró no existían. Fue por parte de los trabajos surgidos de la dinámica del discurrir académico, desde la perspectiva no de Einstein sino de Weyl, que Bondi, Pirani, Robinson y Trautman, en la década de 1950, posterior al fallecimiento de Einstein, las "ondas gravitacionales" fueron reintroducidas y motivaron que experimentalmente se buscaran. En el 2002, a partir del experimento de VLBI de Sergei Kopeikin fue establecida su supuesta velocidad, sin que obtuviera el reconocimiento unánime de la comunidad de científicos sino diviéndolos. Y fue en febrero de 2016, que la colaboración aLIGO-aVirgo anunciaran haberlas detectado por primera vez. En este trabajo se presenta la historia que conllevo a este supuesto descubrimiento y se plantea que las ondas detectadas son realmente del vacío cuántico en el cual está inmerso todo lo existente, tésis del autor expuesta inmediatamente como respuesta a ese anunció de 2016.

From the geometric formulation of gravity, according to the Einstein-Grosmann-Hilbert equations, of November 1915, as the geodesic movement in the semirimennian manifold of positive curvature, spacetime, where due to absence of symmetries, the conservation of energy-impulse is not possible taking together the material processes and that of the gravitational geometric field, however, given those symmetries in the flat Minkowski spacetime, using the De Sitter model, Einstein linearizing gravitation, of course, really in the absence of gravity, in 1916, purged of some (...) mathematical errors in 1918, he introduced "gravitational waves" as disturbances in the curvature of space, and in the absence of knowing physically what spacetime is and philosophically in dispute, that previously in 1936 and definitively in 1937, Einstein showed they did not exist. It was through the works arising from the dynamics of academic discourse, from the perspective not of Einstein but of Weyl, that Bondi, Pirani, Robinson and Trautman, in the 1950s, after Einstein's death, "gravitational waves" were reintroduced and led to experimental search. In 2002, from Sergei Kopeikin's VLBI experiment, its supposed speed was established, without obtaining unanimous recognition from the community of scientists but rather dividing them. And it was in February 2016 that the aLIGO-aVirgo collaboration announced that they had detected them for the first time. In this work, the history that led to this supposed discovery is presented and it is stated that the waves detected are really from the quantum vacuum in which everything that exists is immersed, the author's thesis exposed immediately in response to that 2016 announcement.

Based on the Russian school of Logunov and others, with the contribution of Tom van Flandern, and his previous works on space-time, gravitational waves and speed of the gravity, the author discusses the theory of the time-space fluid that results from the supposed gravitational waves that would have detected LIGO, and reaffirms the space-time as a structural geometric property of the dynamic matter (radiation, matter and quantum vacuum), now with the strong argument that without escape, in an unnatural way, (...) the physicists and philosophers of science confer the conception of the author to that ridiculous material-space-time, while depriving Matter, of the intrinsic space-time. In addition, he warns about the conceptual contradiction existing between NASA and Caltech over gravitational waves, being absurd the concept of Caltech, operator of LIGO, since gravitational waves would propagate in five non-detectable dimensions. NASA valiant and validly recognizes that they would be waves of space; therefore, there are no space-time waves that correspond to gravitational waves that, according to the great current of relativistic physicists, would exist. Finally, the author reaffirms that the quadrupole waves detected by LIGO are waves of the quantum vacuum. (shrink)

This dissertation explores the influence of time constraints on different research practices. The first two parts present case studies, which serve as a basis for discussing the epistemological and ethical implications of temporal limitations in scientific research. Part I is a case study on gravitational wave research, conducted by the LIGO Scientific Collaboration. This exemplifies fundamental research – without immediate societal applications, open-ended in terms of timeline and in terms of research goals. It is based, in part, on qualitative (...) interviews conducted with gravitational wave physicists. I show that considerations about time and speed play a role in every stage of research: goal setting, method design, and the evaluation and communication of results. Part II provides a case study on translational medicine, an approach explicitly dedicated to accelerating research in order to develop and implement new therapies. This epitomizes applied research with high social stakes, motivated by non-epistemic goals. Here, epistemic trade-offs between speed and reliability intersect with ethical trade-offs between different types of harms. In Part III, the insights from both of these case studies are used as the basis for a more general discussion concerning the pragmatic aspects of epistemic practices, especially in relation to current debates centered on the role of values in science. A particular focus is on the value of speed and the ability to generate reliable results, either via choice of methods, or via decisions about which goals to set, as well as decisions about when to stop further testing. The primary thesis of the dissertation is that pragmatic considerations stemming from limitations of resources are a necessary feature of the pursuit of epistemic aims, and that the epistemic is thus inherently pragmatic.
