The Punctuated Participatory Anthropic Principle

  1. John Wheeler came up with the "Participatory Anthropic Principle," in which the entire early universe expands as one vast collection of entangled particles until an "observer" becomes one of the quantum possibilities, at which point that "observer" observes itself into actuality.
  2. What Wheeler failed to note was the "petunia problem" (citing Douglas Adams in Hitchhiker's Guide to the Galaxy, where a sperm whale and a bowl of petunias appear in mid-air and then crash to the ground). An "observer" can exist long enough to "collapse the quantum wavefunction" yet not be able to exist very long after that. Wheeler's original Participatory Anthropic Principle must be modified into a Punctuated Participatory Anthropic Principle ("PPAP") in light of this problem.
  3. A PPAP should leave a distinctive trail in the genome that is as recognizable as the trail a subatomic particle leaves in a bubble chamber. This is because there are two kinds of "evolution" in operation--an "observer-driven evolution" that defies all odds as it produces the most intelligent organism possible in the shortest possible time, and a random "devolution" that cascades down from these more advanced organisms.
  4. On Earth, PPAP would predict some radical anomalies in the fossil record. There should be a few impossibly advanced species very early in the fossil record, with many variations radiating out from that ancestral stock. (This goes directly against the Darwinian model of long, slow growth towards the more advanced species.)
  5. The secular scientists should be able to take the model and look for anomalies. The most obvious ones are (a) the sudden appearance of life on earth which leads some to suggest some form of panspermia, (b) the radical diversification of multicellular animal life in the Cambrian Explosion, and (c) the perplexingly early appearance of birds in the fossil record.
  6. PPAP suggests that humans are not the only intelligent life-forms in the universe. This means that even the most secular scientists might want to take a second look at the book of Genesis. Genesis 1 might not be just a man-made myth; it could contain a communication from another intelligence (whether God, "angels," "fallen angels," or extra-terrestrial biological beings). PPAP makes it possible for secular people to consider the account of Genesis 1 as reliable information about a pre-human history.
  7. When we add Scripture to this reasoning, we get more specific about what to look for in the fossil and/or DNA record. Genesis 1 tells us that flowering plants appeared before the sun (1:11), the lights in the heavens appeared for signs and seasons (1:14), and birds appeared before land animals (1:20).
  • If flowering plants appeared before the sun, they must have appeared on some other planet. This suggests that pollen grains can travel between the stars. There is very little research on this topic (it is known as "reverse panspermia"), so I can't say whether it is possible or not--just that it is a falsifiable prediction of the PPAP hypothesis.
  • If the sun, moon, and stars appeared for signs and for seasons in a PPAP universe, an "observer" probably observed them. Modern molluscs have a camera eye that is startlingly similar to the vertebrate eye. Octopi are unbelievably intelligent-- but have terribly short lifespans (one or two years). They don't leave much in the way of fossils, so we need to look at the modern DNA to hunt for an common ancestor to link the vertebrate eye with a Cambrian observer.
  • Birds are the easiest observer to find in the fossil record. Avian intelligence is very high, and bird bones are preserved often enough to suggest that dinosaurs descended from birds, not vice versa. The "birds came first" theory is based solely on fossil evidence, not any Scripture--but Genesis 1:20 fits perfectly with PPAP.

Of Dreams and Time

The Bible tells of Joseph the dreamer, whose brothers envied him and kidnapped him and sold him into slavery. The story goes on to tell of Pharaoh the dreamer, who saw seven fat cows and seven skinny cows and put all Egypt under Joseph's rule. Joseph reveals the metaphysics behind it all in Genesis 45:5-8.

I am your brother, Joseph, whom you sold into Egypt. And now do not be distressed or angry with yourselves because you sold me here, for God sent me before you to preserve life.... God sent me before you to preserve for you a remnant on earth, and to keep alive for you many survivors. So it was not you who sent me here, but God.

This tale doesn't fit the modern worldview. The "experts" agree that we live in a universe of time and space and matter and energy, governed by natural laws that leave no place for dreams or deities. The consensus is that God is dead and chance is king and dreams are just coincidence.

This means that science doesn't just conflict with the first few chapter of Genesis--modern materialism contradicts the clear teaching of Scripture from start to finish. It may be easier to pick a fight over whether the world was made in "six twenty-four hour days" or not, but the real question to be resolved is whether God acts within time and space. If He does, then something in our physics is either false or incomplete. If He doesn't, then the whole Bible is in error, not just a few verses here and there.

The biggest hole in modern physics has to do with time. Mainstream physics says there is just one timeline, and it is guided just by chance. Picture a single, kinky thread writhing through fifteen billion light-years of empty immensity--then have it accidentally wind up on the one small bit of all this void that isn't empty, and you've got the best that modern science has to offer to explain how we got here.

David Deutsch is a secular physicist, but not in the mainstream. His picture of the universe makes more sense to me--he fills the void with timelines until there isn't any emptiness left. If there is some small statistical chance that particles could come together into self-replicating structures, Deutsch's multiverse will find it. If every possible world exists, then this one does--and so does Harry Potter's. But that goes way too far for mainstream physics.

John Wheeler offered a different option. The man who coined the term "black hole" believed the future could cause the past. (That sounds bizarre to the ordinary layman, but so does the rest of quantum physics.) Wheeler's participatory anthropic principle sketched out a way for future minds to create their own past. In Wheeler's model, there is only one thread through fifteen billion light years of time and space, but it isn't "kinky." It marks the shortest possible path from pure possibility to actual intelligence.

The story of Joseph doesn't make sense in two of these three models (one "kinky" timeline, all possible timelines, or one "guided" timeline). In the mainstream model, dreams don't come true. The stories in Genesis are just that--stories, myths made up by later generations around some campfire. In Deutsch's multiverse, the story may be true but it doesn't mean anything. Sure, Pharaoh dreamed of seven fat cows and seven skinny cows--in this timeline. But he dreamed of six fat cows and thirteen tadpoles in another. If everything happens, nothing matters.

In a world where the future causes the past, however, dreams fit nicely into physics. The dreams are essential to the outcome. If the outcome comes first, the dreams help make it happen. The most astonishing coincidences aren't coincidences at all in a "participatory" universe.

The Participatory Anthropic Principle

Science studies space, time, matter, and energy. Does it have a place for truth, love, beauty, or justice? Each of these depends upon “consciousness,” an “emergent property” of the material world. If intelligence here on Earth is just a statistical fluke in an otherwise lifeless universe, then categories like “beauty” or “justice” have no intrinsic meaning. In that kind of a universe, “meaning” is what humans impose on their surroundings, not something they discover within them.

Modern methodogical materialism takes the position that intelligence here on Earth is, in fact, just a statistical fluke. Our understanding of the laws of physics makes it possible, in theory, to spell out a chain of events from some kind of initial quantum fluctuation through a warm, wet pond somewhere in Earth’s pre-history to the first anthropoid who ever grunted, “I think, therefore I am!” The materialist believes that because such a sequence can be imagined, no other explanations are required.

But is this sound reasoning? If I take the latest Hollywood thriller, I can show you a single chain of events from the opening credits through the 90 mile-per-hour car chase on the wrong lane of a crowded freeway to the multi-billion dollar jackpot at the end. Is a mere unbroken sequence of events enough to prove the materialism?

John Wheeler (the physicist who coined the term “black hole”) proposed a “participatory anthropic principle” which makes the quantum concept of an “observation” even more basic than the physical realities of space, time, matter, and energy. In Wheeler’s model, an “observation” by a material being billions of years after the Big Bang that “caused” space, time, matter, and energy to exist in the first place.

Occam's Razor

The debate (if it can be called that) about Intelligent Design is raging through cyberspace, but I can't find many people who are willing to look past this discussion to the next one. Buried deep within today's controversy is a bigger one that nobody wants to deal with. It is the clash between one invisible God and many invisible universes.

If today's materialists were willing to examine the evidence, they would have to admit that there are "gaps" in the materialistic explanation of what we see. These gaps include the following:
  • Why is there something rather than nothing?
  • Why is the universe as orderly as it is, instead of a chaotic fog of particles?
  • Why do the fundamental physical constants make carbon-based life possible?
  • How did the first self-replicating molecule take shape?
If we could find a satisfactory answer for each of those questions, materialism as we know it today might be intellectually satisfying. As it is, however, today's materialists must skip over the really big questions to get to the ones they have answers for.

The most satisfying materialistic answer that I have found is in the notion of a "multiverse." This theory proposes that there are countless alternate and/or parallel universes that we cannot detect, and that the sheer number of such universes overwhelms the improbability of life in a materialist monoverse.

But the notion of countless invisible universes forces us to take a good hard look at Occam's Razor, the rule of thumb that leads us to choose the simpler of any two competing theories. One should not "multiply the essences" needlessly, William of Ockham insisted, and so should choose the theory with less moving parts, so to speak.

But which theory is simpler: a materialistic multiverse, with countless invisible universes, or a theistic monoverse, with one invisible God?
