Any number in existence, i.e. infinite amount of numbers
Pythagoras and his followers denied the existence of irrational numbers, believing that all quantities could be expressed as ratios of integers. This belief was challenged when they discovered that the square root of 2 could not be represented as a fraction, leading to a crisis in their mathematical philosophy. The realization of irrational numbers contradicted their foundational principles, prompting a reevaluation of their understanding of numbers.
Irrational numbers were known in India around 7th Century BCE but there existence as a different class of number but they had not proved their existence. That is sometimes attributed to Hippasus, a Greek philosopher of the Pythagorean school in the 5th Century BCE.
