There are many different metrics to measure the expansion of regulatory power, which has frankly grown to the point where judging its full extent and cost is harder than calculating the duration of the Big Bang. You might say some of the same quantum uncertainty principles are involved.

It’s a lot easier to camp out at the South Pole and look for gravity waves in the background radiation of the universe.
