A number so large your head collapses into a black hole

A number so epic it will collapse your brain into a black hole! Yet Tony Padilla and Matt Parker take the risk of discussing its magnitude. Watch with caution.

Without looking I'll assume this can apply directly to String Theory and the number of "structural dimensions" needed in order for it to work. I'll look quickly and see. However if I'm wrong, the reason I made this quick assumption is knowing about their "dimensional conundrum": how many are there? I'll go check, their may be a strange link even if not thought of already as they deal, in some ways, with a bit of the same problem, indirectly. BRB.

edit-
Only a limited number of connections, so more or less, NO. They are not as of right now connected. But, if they both end up on the same number of dimensions--the number is the same--that WOULD indeed be interesting. Something to put on the back burner me thinks, to remember for a far off or not so far off future...

These are pretty pansy little numbers; sure they're kind of long, but they're computable. We know digits of this number.

If you want truly large numbers, you want to use the Busy beaver function. These are numbers for which we can say beautiful, absolute things like:

in the context of ordinary mathematics, neither the value nor any upper-bound of Σ(10↑↑10) can be proven


That is a majestic bloody number.
