The silence of infinite spaces

Is the universe finite or infinite? TXT answers the question by reviewing all related cosmological theories, Tycho Brahe at the Big Bang theory.
Since ancient times, it sest asked. The Greeks not too naimait the idea of ​​infinity. But if the universe is finite, can be asked as Archytas of Tarentum (428-347) who reasoned thus: "Suppose that the universe has an edge. If I am close to this edge, can I extend the hand beyond this edge? And, if I can, there must be a space beyond the limits of the universe. There must therefore be a new space, beyond the outer sphere of the stars. And sil is still a new area beyond the edge, space must sétendre indefinitely. "? Sil is infinite, that infinity is it "current" as suggested by Aristotle, or is it strictly "potential" denying him any physical existence to confine the mathematical sphere?
Cantor failed in his demonstration of his hypothesis of a actual infinity, Paul Cohen explains why she wasnt in the state demonstrable from the axioms of set theory, confirmed by dincomplétude Gödel's theorem that the consistency of a system can not be demonstrated solely on the basis of the axioms hereon and it takes out to find the right.
But if the universe is infinite, why is the dark night? For Kepler, which rejected the idea of ​​a boundless universe, it's black, otherwise we would have been in daylight and darkness of the night would have been incomprehensible since linfinité star should emit continuous light. In this it is mistaken, and Edgar Poe, for a brilliant poetic intuition, anticipating the Big Bang theory explaining the dark night that the universe is still expanding and that there is no enough of stars still to fill light sky. However, the Big Bang theory in an inflationary universe leaves in dombrés areas. In making the content of the census universe (0.5% of luminous matter, 4.5% of ordinary dark matter, 24% dark matter and exotic black 71% of energy), we discovered that the universe sest just the critical density, its geometry is flat and its curvature zero. This means that the universe may be as well finished quinfini. Everything depends on its topology. Sil is infinite, and as there are only a finite number of particles of matter, their combinations must eventually repeat itself in an infinite universe, there would be, as Nietzsche foresaw washed and Blanqui, an infinite number of lookalikes of us in parallel worlds as the paradox of the eternal return.
Linfini took an even more dizzying twist with the introduction in quantum mechanics parallel universe branching off, as in the novel by Borges, but also the inflationary multiverse containing an infinity dunivers- bubbles, with world-branes, and with that of the universe holographic. But these theories suffer from the defect never be verifiable, and may pour into metaphysics. According to the Vedas, this is Brahman who dreamed universe, and every breath is the duration of a dexistence universe from its birth to its destruction, thus providing a troubling analogy universe-branes, each collision gives rise to a world.
A reading that is breathtaking.
