Title: Space expansion and shrinkage
Inventor: KOBORI SHIZU
IPC: 00000/00
Filed: 2012-04-21
Abstract: PROBLEM TO BE SOLVED: To clarify the problems of the behavior of space when assuming to continuously expand, or that when shrinking, and of a range of an age possible to exist in a cylindrical state when continuously expanding, and of the possibility of generating inflation again when assuming to shrink.SOLUTION: A problem of a behavior of space is clarified by considering dividing the formula of an orbital energy of space into three types. A first type is a case where a current orbital energy is continued, a second type is a case where the orbital energy becomes 10 times (or 1/10), and a third type is a case where 10solar mass of a central black hole changes. By the formula of the orbital energy, the orbital energy (attractive force) of orbital radius of the age, and velocity are figured out. By determining that the orbital energy (attractive force) of a galactic end is the attractive force gravitating to the black hole, the space is made to be a range enabling existence in a cylindrical state until such orbital energy. When assuming the orbital energy of (light velocity)to be inflation, the orbital energy lessens and exists in the space center because the energy of inflation is confined to the space center.
