everything is infinite and so is nothing but the things in the system we call the functional subjective universe require the imposition of a standard of limits and boundaries which fundamentally counters the notion of infinity... but seeing as everything and nothing are the same (or diametric opposite [its not paradoxical], and everything in everything is composed of the same fundamentals, there is no differentiation, and thus everything and nothing are 0, the true infinity
Our brains dont really have a "program" to contemplate something like that. We can make opinions based on the definition of infinite, but it doesn't really register.
