In mathematics, model theory is the study of (classes of) mathematical structures such as groups, fields, graphs, or even universes of set theory, using tools from mathematical logic. A structure that gives meaning to the sentences of a formal language is called a model for the language. If a model for a language moreover satisfies a particular sentence or theory (set of sentences), it is called a model of the sentence or theory. Model theory has close ties to algebra and universal algebra. This article focuses on finitary first order model theory of infinite structures. Finite model theory, which concentrates on finite structures, diverges significantly from the study of infinite structures in both the problems studied and the techniques used. Model theory in higher-order logics or infinitary logics is hampered by the fact that completeness does not in general hold for these logics. However, a great deal of study has also been done in such languages. From Wikipedia under the

That is why not all galaxies flow in the predicted pattern of an outward expansion from the point of origin. That is because the contradicting galaxies are from a different points of origin, a different big bang. Each big bang creates a sphereical cluster of galaxies that can sometimes overlap in this infinite universe of galaxy "bubbles". The Big bang is the start of a new galaxy "bubble" but also the death of a black hole. The black holes are vacuum cleaners that suck up and stores matter, when they collide or when they reach crittical mass, they explode in a big bang creating a new galaxy bubble. There is no "Big crunch" just black holes. Is this model not more plausible then the "Big… [cont.] Asked by Dead Inside - Tue Jul 10 12:34:37 2007 - - 3 Answers - 0 Comments A. All of these theories (yours included) are shots in the dark. We know nothing, nothing. We seem to need to convince ourselves that we've got a handle on things, but it's not true.

Q. thanks:) Asked by soccerfan_001 - Sun Oct 4 00:04:15 2009 - - 1 Answers - 0 Comments A. An economic model uses an economic theory as a framework to build the mathematical relationship among economic variables simultaneously.
