on the subject of infinity

One thing I find hard to fully understand is the concept of infinity, Logically, I know it means forever, however, there aren't too many things that are truly infinite.

A way to try and feel it for yourself is to visualize space, beyond earth and the milky way galaxy, beyond every single star and black hole. There is no "edge" of space, it doesn't end, space is not contained in a box. Beyond void is void, if there is an observable end, we have not found it, and likely will not. So for now, i see space as truly infinite.

Another thing I've thought about which is related to shifting in the concept of infinity. The multiverse theory says that there are infinite realities, but what does that really mean? It means that for every tiny detail on the entire planet, there is a reality where everything is the exact same except for that one tiny detail. Picture a speck of dust on the floor. There are an insane amount of realities where that single piece of dust it less than a millimeter moved from where it is, and realities where that single speck of dust is every single place in the entire multiverse, which as I just said is infinite.

I think infinite is a hard concept because we cannot see or feel it, we cannot check for ourselves if something is "truly infinite" because if it was we would die in the pursuit of checking. It is a very interesting rabbit hole of thought though !! lemme know what u guys think in the comments lol :))
