i believe that
"you can't imagine the size of this"
is a reference to google. a googol is a number originally conceived as a thought experiment looking for a number that the mind couldn't comprehend
can anon imagine the size of a broad and vast conspiracy? imagine? sure. i imagine the governments of every country are against us…. and they have a secret inner world… and a base on the mooooon.
we can imagine many big conspiracies. but you can't really imagine a googol of something.
ergo
google is at the heart of the conspiracy.
