Is infinity rational or irrational ? Is infinity abstract or real ? Actual infinity or potential infinity ? Effectively infinite or passive infinite ? Bad, unreasonable infinite or reasonable infinite ? ==. Again and again Infinity appears in many physical and mathematical problems. I don’t say about mathematical infinity, I say about physical infinity. Does Physical Infinity exist ? If it exist then: 1) What is connection between the infinity and the concreteness ? 2) What is connection between infinity and quality ? 3) How to explain the inconsistent character between the infinity and the concreteness ? ===. # Part Physics: Theoretical applications of physical infinity . ==. This point of view does not mean that infinity cannot be used in physics . . . . . . In quantum field theory infinities arise which need to be interpreted in such a way as to lead to a physically meaningful result, a process called renormalization .
However, there are some theoretical circumstances where the end result is infinity. One example is the singularity in the description of black holes. Some solutions of the equations of the general theory of relativity allow for finite mass distributions of zero size, and thus infinite density. This is an example of what is called a mathematical singularity, or a point where a physical theory breaks down. This does not necessarily mean that physical infinities exist; it may mean simply that the theory is incapable of describing the situation properly. Two other examples occur in inverse-square force laws of the gravitational force equation of Newtonian gravity and Coulomb's law of electrostatics. At r=0 these equations evaluate to infinities. / Part Physics: Theoretical applications of physical infinity . http://en.wikipedia.org/wiki/Infinity / ================. -- You received this message because you are subscribed to the Google Groups "Epistemology" group.
