Bigger Than Time Itself
I've just been down a very interesting if mind-boggling rabbit-hole, courtesy of the podcast ' The Rest is Science ', which is co-presented by Professor Hannah Fry and Micheal Stevens ; talking about very large finite numbers . Discounting the various flavours of infinity that theoretically exist, albeit mostly conceptually, very large finite numbers are numbers that, given enough time, could actually be counted, but are in any remotely practical sense infinite to the human mind's conception. Even one of the 'smaller numbers they discussed during the podcast - Fifty-Two Factorial , or 52!, 1x2x3x4x5 ... x52 - is pretty much inconceivable to most people, even given that it 'only' represents the total number of possible orderings in a deck of cards: approximately 8.0658 x 10⁶⁷, or 8-ish followed by 67 zeroes. The method of mentally imaging the scale of this number that was used in the podcast by Stevens ran roughly along these lines: Set a timer to count dow...
