I love weird maths stuff and I'm sure we have some PHD Maths graduates in this forum, I'm not one of them. I defy anyone to get there head around this number. If you try to understand it your mind just goes bonkers.

And the really daft thing about this large number is that it is actually infinitesimal small compared to what could be the largest known number.

The second daft thing is that the actual answer to this maths problem is suspected to be.................. 6.
 
that may be , but my god that is so far over my head its hitting satellites, i dunno how you can get your head round this kinda stuff!
 
That's a pretty cool number but if you multiply it by 1.61080339887 you get Golden Grahams which is even more impressive.
 
Is the largest number possible the area of the universe in cubic planck lengths? :cool:
Well, the largest number possible to represent in full.

Edit: Hahahaha, didn't read the wiki article :p

Indeed, the observable universe is far too small to contain an ordinary digital representation of Graham's number, assuming that each digit occupies at least one Planck volume.
