Discovery of 0 changed nothing about how 1 and 2 interact. There is infinity left to discover and the more we discover the less we know, but there are truths to this universe that have existed since inception and are unchanging regardless of how we try to arrive at them, if we even can. Gödel's incompleteness theorem proves that there will always be truth in a system of logic that will exist and yey will not be provable within that system, such is how deeply truths are ingrained in the world. The mindset that truths are subjective and bendable are rather highly egoistic or arfive from the minds of highly confused individuals.
