Actually this only concept in mathematics needs few minutes to verify its legality of being considered as any real good and useful concept or just a mere big fallacy that is more than meaningless and a kind of madness, wonder!
It is also stranger how it led the mathematicians to built on it so many huge volumes of baseless mathematics that is good enough for little carpentry works
And even much stranger that they had generated so many types of more infinities to the science of mathematics.
But the oddest thing is that mainstream common mathematicians never realize that such concepts are so meaningless the same way their results that they obtain relying on that fake concept
And naturally such concept is indeed a real paradise for any jugglers to create so many meaningless games and shamelessly consider it as a real science
But the fact that any theorem or formula or result that is associated with such silly concept as infinity, is also so silly but may be good for entertainment
Since mainly, no definite rules with it, nor any real existence (being unreal: by its own definition)
So, this flowed concept would make it very easy in the near future to make mathematics get doubled and tripled and even grows indefinitely in the fake unreal direction to its collapsed limits, for sure
However, many refutations of such meaningless concept was provided in my posts, beside many others
