One of your very early philosophers came to the conclusion that a fully competent mind, from a study of one fact or artifact belonging to any given universe, could construct or visualize that universe, from the instant of its creation to its ultimate end . . .

—First Lensman

If any one of you will concentrate upon one single fact, or small object, such as a pebble or the seed of a plant or other creature, for as short a period of time as one hundred of your years, you will begin to perceive its truth.

—Gray Lensman

I am reasonably sure that a single pebble, taken from a beach of our own Earth, does not specify the continents and countries, politics and people of this Earth. Other planets in space and time, other Everett branches, would generate the same pebble.

On the other hand, the identity of a single pebble would seem to include our laws of physics. In that sense the entirety of our Universe—all the Everett branches—would be implied by the pebble.¹

From the study of that single pebble you could see the laws of physics and all they imply. Thinking about those laws of physics, you can see that planets will form, and you can guess that the pebble came from such a planet. The internal crystals and molecular formations of the pebble developed under gravity, which tells you something about the planet’s mass; the mix of elements in the pebble tells you something about the planet’s formation.

I am not a geologist, so I don’t know to which mysteries geologists are privy. But I find it very easy to imagine showing a geologist a pebble, and saying, “This pebble came from a beach at Half Moon Bay,” and the geologist immediately says, “I’m confused,” or even, “You liar.” Maybe it’s the wrong kind of rock, or the pebble isn’t worn enough to be from a beach—I don’t know pebbles well enough to guess the linkages and signatures by which I might be caught, which is the point.

“Only God can tell a truly plausible lie.” I wonder if there was ever a religion that developed this as a proverb? I would (falsifiably) guess not: it’s a rationalist sentiment, even if you cast it in theological metaphor. Saying “everything is interconnected to everything else, because God mad...
