A couple of follow-ups.

(1) “Can’t we go back to calling Gypsies ‘Gypsies’?” I beseeched in my blog roundup.

A Radio Derb listener responded:  “How about we call them ‘Gatsbies’?”

(2) Several readers failed to understand Outside In’s point, also linked from my blog roundup, about the universe being suspiciously young.

I think the fundamental problem here is a general failure to realize how stunningly BIG big numbers can be.  Even in Planck ticks the cosmos is only 8.1×10^60 ticks old; in seconds, 4.4×10^17; in years, 1.4×10^10

Taking numbers in all generality, those are laughably small.  The biggest of them is written out in full with only 61 digits.  Compare A(4,3) from my primer on Ackerman’s function.

A(4, 3) is a number of roughly 600 billion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion

Note that that's not the number; that's the number of digits in the number.

That's a big number. Imagine what A(100, 100) looks like;  or for that matter, since we're talking recursion, A(A(100, 100), A(100, 100)). There's a lot of room in infinity.

So why isn’t the age of the universe more like A(4,3) years old?  Or A(100, 100) years?  Or A(A(A(A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))))), A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))))), A(A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))))), A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))))))), A(A(A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))))), A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))))), A(A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))))), A(A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))), A(A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100))), A(A(A(100, 100), A(100, 100)), A(A(100, 100), A(100, 100)))))))) years?

Now that last one’s a number!  It actually is a number, though, with factors, roots, and all the other things numbers have.  Its eighteenth digit (say) is some definite digit; quite likely there’s a mathematician somewhere who could figure out which digit (don’t ask me).

So why isn’t the universe that number of years, or seconds, or Planck ticks old?  Why are we tiddling around here in the barely-registering billions, trillions, and 10^60s?  It’s not a trivial question.

(3) A reader wonders why I keep reading The Economist when they publish the kind of dreck I report here?

Answer:  As a useful weekly reminder that globalist, neocon Conservatism, Inc. is a wholly-owned subsidiary of Cultural Marxism.
