I was recently questioned about an infinite universe. I like the math definition of infinity as increases without bound/end. I think that is how it is used in math equations. That is, the concept merely fills in an unknown in an equation. In physics it becomes a cop-out for have no model. (perhaps, this is a bit harsh.) SO, I ask what part in physics does the concept of “infinity” play in forming predictions and useful to humanity concepts?
