As The Watcher Explains Here, The Marvel Multiverse Is Based off Infinite Quantum Realities, Which each Infinitsmal Difference Creating another Infninite Quantum Realities, Ad infinitum.
Cantor used Set Theory to prove that some infinities are greater than others Before him everyone thought that if you add any number to infinity it remains infinity, and while this is true for most numbers, other numbers and operations can make infinities larger Transfinite is the infinite set of infinities so ∞ [0. 1. 2. ... , ∞ , ∞ +1 , ∞ +2, ...} would be that number and then you can really go crazy and make a set containing all versions of that number.
There is a Transinfinite amount of Neverending Universes In the Marvel Multiverse, Essentially, There exist a Infinite series of Infinite Marvel Universes.

For instance: Numbers are infinite. So are odd numbers. Yet, by definition, there are twice as many numbers as there are odd numbers. One "Infinity" is included within a larger "Infinity." (...) Goerg Cantor, a russian monk at the turn of this century, was the first to study what he called "Transfinite" numbers, starting with Aleph - An infinite series of infinite numbers, all greater than each other. Quite understandably, he died a madman. Yet, it is of such concepts and more -- That the Multiverse is made. For the Multiverse is literally a transfinite number -- That is, a number greater than infinity -- of universes. These universes are often popularly called "Dimensions."]
When Adam Warlock Goes Through the Cosmic Vortex via a wormhole iirc, The Cosmic Vortex is essentially a Graveyard of Universes Erased by the UN, Adam Described it as "Spiraling Upwards to a Infinity beyond Infinity"
The Nexus of All Realities itself Contains Countless Doorways, With Each Door leading to a Infinite amount of Possibilities, And there is a Nexus for each Universe in Marvel.
