    Well, Vsauce, I'm sorry, but I do not want to dig straight down, I think none of us do. Not because we are, scared, or, it being impossible, but because we dont want to dig straight down just to loose 5 hours worth of strip mining for diamonds, just to fall into lava. It sounds fun, but you're in your own boat, sorry.

    Hold up, stirring coffee *can't* follow the fixed point law. It allows for "cutting and pasting": its a liquid.

    Take a toroidal shaped grouping of the liquid (that contains all of it) and rotate it around the circle defining the torroid, then rotate around the center of that circle. No points will remain fixed in place: the first rotation leaves only the points on the circle where they started, but the second rotation moves all of those points without moving any other point back to its start.

    @Vsauce - The number shown at 9:00 doesn't make sense. The subscript for an Aleph number is always an "ordinal number", not a "cardinal number". So, an Aleph subscript doesn't make sense. I think you wanted to use Omega instead of Aleph.

    And,∞=≠∞,because,even what fraction you give over infinity,whatever you add or subtract,whatever you divide or multiply,even what operation you do to it(like powers,square roots,cube roots,etc.),it's still infinity,but is a different number.

    Therefore,it is in a state of superposition,though,it is "numerical superposition", and,∞ can't be 0,because ∞-1=∞,but 0-1=-1.
