Abstract
This part treats about paradoxes that arise when the human thought see itself in a vicious circle of reasoning. Such paradoxes arise from questions confined to the beginning and ends of all things.
Drops of Quantum Time 2
Antinomies
Despite the short time of our lives, has someone observed apparent movement of stars? If we could travel at light speed, we would see the Moon in a second pass to our side, and the Sun approaching precipitously from our bow, but in about eight minutes we would see already in our rear. From there, we would be hanging in a void amazing, the distant stars would appear yet quite, and perhaps only the star Alpha Centauri which is about 3.4 light years (one light year is about 9.5 trillion kilometers) from Earth would seem to us to move a little, or maybe not.
The distances within our Universe are almost immeasurable. For the reader to have an idea, our galaxy, the Milky Way, has a larger diameter 100,000 light- years, and contain about 200 or 300 billion stars that vary in size up to colossal dimensions (red giants) in relation to our Sun which is a medium size star. The Milky Way is part of a group of galaxies called the Local Group in which highlight the Large Magellanic Cloud and the Andromeda Galaxy. For our scale lifetime this galaxy is at unimaginable distance, about 2.9 million light- years from Earth and is larger than the Milky Way. For now let's go back to Alpha Centauri. According calculations made by writer science fiction and biochemist Isaac Asimov (1920-1992), would take about one million years to go near that star, taking into account the maximum speed (about 27,000 km / h) that we currently reach with our satellites orbiting around the Earth. This means that we would have to get there from Earth when we were hominids, that is, when we had just descended from the trees, according to the Theory of Evolution. What do you conclude, even partially?
And beyond the Andromeda galaxy? According to observations of the Hubble Space Telescope already have been observed around 100 billion galaxies approximately 12 billion light years from Earth. Near close would be at the beginning of time according to the standard model of Big Bang, that is, about 13.5 billion light- years.
Remember that in the conventional model of the origin of the Universe, Big Bang, space, matter and time emerge from this big explosion. Still does not make two or three decades, physicists have said it made no sense to ask what existed before Big Bang. Already with string theory the time had no beginning or end. Well, if so, it is good to fit these concepts into what philosophers regard as antinomies of human thought. Look:
'The antinomies are insoluble dilemmas arising from a science that seeks to transcend the experience. Thus, for example, when one take notice know whether, in space, the world is finite or infinite, the thought repels any of these assumptions: beyond any limit we are led to conceive of something more remote and so on indefinitely, and yet the infinite is inconceivable. Otherwise: The world had a beginning in time? We can not conceive eternity, but we can also devise a starting point in the past, without understanding, incontinent, that before that point there was already something. Had the chain of causes that science studies, a beginning, a First Cause? Yes, because we can not conceive an infinite chain, and also not because a first uncaused cause is equally inconceivable '(Histria da Filosofia, Will James Durante, 1885-1981, 7th edition translated from the original, The Story of Philosophy , Companhia Editora Nacional, Brazil, 1948).
So, wants to give rise to the time or not, you get to insoluble contradictions. But look at Einstein's thought: 'I am convinced that philosophers have caused an adverse effect on the progress of scientific thinking in removing certain fundamental concepts of the domain of empiricism, where they are under our control, to the intangible heights of the a priori. 'Or: People ordinarily are used to study geometry divorced from any relationship between their concepts and experience. There are advantages to isolate what is purely logical and independent of what it is, in principle, incomplete empiricism. This is satisfactory to the pure mathematician. He is satisfied if he can deduce their theorems from axioms correctly, ie, no errors in logic. The question about whether Euclidean geometry is true or false does not concern him. But for our purposes it is necessary to combine the fundamental concepts of geometry to natural objects; without such association, the geometry is of no value to the physicist(The Meaning of Relativity, Albert Einstein, Princeton University, 1955).
