is hard to imagine a world different from the three spatial dimensions we know. It might seem that it was always like that, but at some point our universe had to "decide" the appropriate number of dimensions. In addition, we also had to choose between the number of ordinary size and curled (superstring theory). And this decision had a direct impact on the way then was to submit its texture in the makeup of the quantum of action. The
special configuration between regular and compacted spatial dimensions determined that the "tiles" that make up the universe consisted of action, ie the time-energy product. The least action - called by Max Planck h -, is the smallest tile universe, you can not chop and remain stable at a time. Unlike our home soil, "soil" stable universe can only consist of full tiles.
The value of the quantum of action is extremely small, allowing us to see our everyday world with a continuous appearance, the texture of a film with very fine grain. Thus we can distinguish between properties macroscopic matter, which govern our common life, and the microscopic or quantum that determine the behavior of corpuscular world, and we build, every day, and everyday devices for the world as transistors (circuit boards) , electron microscopes and scanning tunneling, superconductors, cryptography and quantum computing, etc.. If the value was much higher as our life would change radically and be governed by the "mysterious" laws of quantum mechanics: corpuscular-wave duality and indeterminacy.
would cease to exist the classic location of an object as well as entities separate consideration of wave and concrete objects. A soccer ball could diffract a light beam, but at the same time would be difficult to clearly identify a site or another. The associated wave would be large enough to influence their behavior as object wave.
The magnitude of the quantum of action was determining the type and magnitude of the warping of space-time dimensions linked to (Weyl and Ricci tensors) at the crucial moment. Similar to how they are interrelated, any material, deformation capacity, its inner structure and its basic form (a wire, an iron or a compact).
geometry has much to do with our world, understood as some form of symmetry, simplicity and elegance, the beauty that Paul Dirac was referring (pictured). The mass warps space-time as a weight deforms the membrane that holds it (general relativity). The modification of the geometry (shape) of any force field incident on the associated load, immersed in it, and the reverse. The number and the manner in which the dimensions were organized at first determined the magnitude and nature of quantification, and its own mysterious laws governing quantum mechanics.
