Graham's Number - Numberphile

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.

the point isn't the large number, it's that it's the largest number with a purpose.

Tell me how multiplying made me "scuk at this" exactly how was I wrong, If its something on how I tried to show exponents thats what g9999... is.

Anything that you can write within 500 characters, that doesn't use the same arrow notation/power tower concept as graham number or reference the graham number itself, is never going to be even remotely as big as g1, let alone g64.

[Trent Houliston]

You wouldn't have even witten enough of it to be noticeable... Seriously, the stupidity of how big that number is is insane

[Peter Geras]

g(g0) > your number. And you multiplied numbers together? Seriously, you suck at this, stop trying.

"1 googolplexianth of a second" is much smaller than the Planck time (~10^-43 s), so that wouldn't work, physically speaking. But again, we would never be able to write it out in any possible form of matter since there are only ~10^80 particles in the known universe. And graham's number is obviously bigger than that.
