THE STATIC UNIVERSE VERSUS THE EXPANDING UNIVERSE

THE STATIC UNIVERSE VERSUS THE EXPANDING UNIVERSE

It should pay attention to the difference because it is determinant for the relativity and the Big Bang.

There are some versions about what is the static universe. For many is spatially infinite and temporarily infinite also. Albert Einstein proposed a change to be considered temporarily infinite, but spatially finite. He said relying on studies of Poincare and Helmholtz.

An expanding universe is one that constantly grows and becomes more and more big, this is, which grows into the future, which implies a continuous motion and a motor so that it drives him and go thus overcoming the present which goes toward the past. The present must be represented as a transition, a fleeting passage that greets the future, then missed in the past.

Growth of space becomes easy to understand sensory if we look as it increases the volume of a balloon is inflated.

Euclidean geometry built on the ideas of point, line and plane based on axioms is suitable for solving the problems of a flat universe. He stopped being useful, Einstein advance it in his first role, to a curvilinear universe. It is important to highlight that the axioms of Euclid are obtained, as all the axioms, nature.   A demonstration of this assertion is in  my blog, reader will find it "new thoughts" with the title "how the axioms are formed" (writted in spanish, como se forman los axiomas, en nuevos pensamientos)

 Geometry is an assembly based on Euclidean axioms, but if these axioms only respond to the presumption of a flat space, it ceases to be a reflection of reality when it is discovered that space is not only flat. It is for this reason that the geometries for flat and curved spaces were formulated, since it was thought that this was the way reality was interpreted, among which those of Riemann and Lobachevsky stand out. But it's not like that. The same arguments are valid now for an expanding universe that needs a new geometry that responds to the new physical description that suggests expansion; therefore, the Riemann geometries are inadequate, whether they are those of constant variation used in relativity or with particular curvatures, since all are valid for static universes, whether flat or curved, and should not be applied to the expanding universe. Better to rethink or at least adjust the idea that gravity is a deformation of geometry.

A new dynamic geometry must be formulated to solve the problems of figures that seem to grow with expansion. The assumption "seems" is justified because the solids show molecular cohesion in such a way that they move as they are in an expansive medium without altering their constitution, changing the coordinates of their spatio-temporal location. For the common problems of our immobile life, as far as the expansion of the universe is concerned, the current geometries are sufficient. It is didactic to think that the two classes of universes: static and expanding are well represented in the option to analyze an event based on their photographs or do so through their video.

The expansion of the universe opens the door of time of the present, past and future. The past is associated with a lower degree of expansion of the universe, this is the same as saying that the past has a physical location in which disappears. This is a transience that weren't for the memory would be soon forgotten, would go unnoticed by the man. The future is always in the field as possible.

The expansion gives us the clear message that time is different to space in nature and which has physical interpretation, of course, different from the space.

 If we persist in talking about space and time, which we have already said are not individualized, it is because we perceive them separately to put them together in the mind. This is a situation that is prone to confusion, so I'm going to expand a little. We see space in an unlimited space that is interrupted by the presence of an obstacle or by the optical insufficiency of the sense of sight that has its limitations; if we eliminate the obstacle that interrupts or we improve our capacity by means of artifices, the space continues being seen, while there is appreciable light by our visual system; but we do not see stretches of space, what we see is an unlimited reference in itself, limited by our shortcomings. Space serves to make things evident, which take shape in relation to this referent. At the time we do not perceive it directly, we deduce it little by little based on our experiences. The man has developed since childhood the ability to understand time, he has done it very slowly until about 7 years. Once the ability to understand time has been developed, it automatically gathers it in the unconscious area with the space it sees, thus it gathers the time it deduces from past experiences with space, in a function exclusive to it, which we call mind. The mind is able to reconstruct space-time by its ability, we realize that we do it leaking because it is notorious that the products of the mind come and go, so that in order to reflect on an issue we must make an effort in order to of counteracting the tendency of the issue to be undone. Obviously, the process is influenced by the organization and limitations of the brain.

 Another data deductible from the expansion is that which confirms that the conditions of the metric that solves the formulas of relativity serve for a static universe. Although relativity was conceived for a static universe, the relativity between space and time that it advocates gives a certain elasticity to the universe that bears some resemblance to expansion, it could well be said that it is an approximation.

Spacetime is not the mere union of space and time in a static universe as relativity treats it, it is rather a fusion of two elements that give birth to a different third of the components, with specific own manifestations, which contradicts some aspects of relativity. Space and time are not related, they are fused. This is understood by the human body that fuses them in the mind in what we call an inherence or union of inseparable things by their nature, which can only be separated by abstraction.

That is, the expansion of the universe makes us discard the static universe, and if we show coherence, the same discard affects relativity.

In another article I propose an explanation about the origin of the expansion
