A quick question regarding the application of Aleph numbers to reality

[Happyman101]

Hi everyone,

I have a quick question about Aleph numbers. Are they even possible? By containing infinity to a finite set, isn’t that essentially disproving the infinity in the first place? Can they be used in an actual scenario’s, or are they just purely hypothetical? Can they be used to measure space, time, and dimensionality? Universes and/or multiverses? Are they scientifically possible?

Thanks for the help.

Aleph numbers are a way of counting types of infinities and have nothing to do with limiting the infiniteness of any infinity.

When infinity first came into existence in math, it was simply infinity.

However, after Cantor described countable infinities vs uncountable infinities the notion of types of infinities was born and so was the idea of wondering about other types of infinities.
