SUMMARY

The discussion clarifies the concept of infinity, asserting that it is an unphysical result with no counterpart in perceptual reality. Infinity is defined as a shorthand for behavior that is unbounded, rather than a tangible entity. The conversation emphasizes that terms like "infinity of natural numbers" should be reframed to "the set of natural numbers is infinite" to maintain mathematical clarity. This perspective aligns with the notion that unphysical models lack predictive power in scientific contexts.

PREREQUISITES
  • Understanding of mathematical terminology, specifically "infinite" and "finite".
  • Basic knowledge of philosophical concepts related to existence and reality.
  • Familiarity with the distinction between physical and unphysical models in science.
  • Awareness of set theory, particularly regarding natural numbers.
NEXT STEPS
  • Research the implications of unphysical models in scientific theories.
  • Explore set theory fundamentals, focusing on infinite sets.
  • Study philosophical discussions on the nature of existence and concepts like 'nothing' and 'everything'.
  • Examine mathematical definitions and properties of infinity in various contexts.
USEFUL FOR

Philosophers, mathematicians, and scientists interested in the conceptual foundations of infinity and its implications in both mathematics and reality.

I have a few questions regarding infinity. Its pretty long so I thought of putting it up on my site instead of here, sorry about that.

The URL is: http://deydas.com/blog/archives/4-What-is-infinity.html .

Can anybody answer my question please?!

Thank you.

I think I can simplify. Infinity is an unphysical result. That it is to say it is meaningless in this universe. It is a concept that has no counterpart in perceptual reality. Much like the concept of 'nothing' or 'everything' in philosophy. In science, unphysical models of perceptual reality are routinely disregarded. They cannot be quantified, hence have no predictive power in this universe.
 
The simplest way to grasp the definition (and like all maths that's all this is) is to only ever use the word infinite, as in not finite, instead of trying to shoe horn in "infinity" which, mathematically, is just a shorthand for behaviour that is unbounded.

Rather than say "there is an infinity of natural numbers", instead think "the set of natural numbers is infinite" ie "the set of natural numbers is not finite".
