|Something there is more immortal even than the stars
What does Cosmic Ancestry imply about the distant future? Specifically, could we, as Cosmic Ancestors ourselves, launch bacteria and viruses to ride in comets to viable planets without limit, and live, in that way, forever? We would face at least two kinds of problems: namely, the two kinds of entropy, thermodynamic and logical (2).
— Walt Whitman (1)
The End and the Big Bang What'sNEW
The Thermodynamic End
Will there always be viable planets, or any planets at all? This is a cosmological question. There seems to be general agreement among cosmologists that, ultimately, the physical universe will wind down to a "heat death". When the law of thermodynamic entropy is applied at the scale of the whole universe, this is the conclusion we reach. So, even if we had taken life to other galaxies, or even if life were already there too, we're all doomed because the stars will all burn out. Perhaps not bacteria, but multicelled life as we know it completely depends on starlight to power photosynthesis. Without any light shining from stars, there won't be viable planets in this universe. So, in the end, we're goners anyway, right? Maybe. If all the stars burned out and the planets became cold, couldn't bacterial spores still remain viable in empty space, as clouds of dust? Something similar was suggested by Steven Frautschi in a 1982 article "Entropy in an Expanding Universe" (3).
And, of course, Hoyle and Wickramasinghe find evidence that a large fraction of interstellar dust is already bacteria and possibly viruses. But if someday all that remains of life is clouds of quiescent bacterial spores and viruses in a cold dark universe, then what?
Cosmologists generally agree that our universe is spatially finite. Huge, yes, but still finite. Having begun in a big bang, it is closed in the way black holes are closed. No matter what technology we might develop, we can't leave. Even if we had left behind clouds of bacterial spores in empty space, they'd be stuck there. The ultimate heat death of the universe might be the end of it after all — right?
Maybe. Fred Hoyle doesn't accept the big bang theory. It was he, incidentally, who coined the term "big bang" in 1950, in one of a series of lectures on BBC radio (3.5). Hoyle has long advocated a "steady state" theory for the universe. In a steady state universe, there is no beginning and no end. A recent elaboration of Hoyle's steady state theory involves perhaps thousands of "major creation events" within this universe in its past (4), or many "little big bangs," which could account for the distribution of galaxies in colliding spherical shells (5).
The Big Bang
It is mystifying that a large part of the community of astronomers and astrophysicists around the world should regard the big bang as a good approximation of something called "the truth" when they are aware of the empirical problems crying out for attention. Can we no longer live with the knowledge that we are ignorant of many things? — John Maddox, 1998 (6)
Most cosmologists agree that our universe started with a big bang, seven or ten or fifteen billion years ago. However, even the accepted inflationary big bang theory has been amended by its authors. They say that the big bang was not necessarily the only big bang. Equally likely and more plausible is the hypothesis that there have been lots of big bangs, and that there will be lots more:
|This illustration of linked universes imitates "Self Reproducing Cosmos" in Linde (1994) Scientific American (9)|
- An analysis of localized inflation suggests that empty space may be spawning universes by the billions, without us ever knowing; was our universe created this way? — M. Mitchell Waldrop, 1987 (7)
- Without much notice, the notion that the Universe may have been through an infinite series of bouts of creation, and not just one, has been making headway in the literature — John Maddox, 1994 (8)
- Recent versions of the inflationary scenario describe the universe as a self-generating fractal that sprouts other inflationary universes — Andrei Linde, 1994 (9)
If there have been many big bangs, then it would be possible for universes to merge. Even if the universe is closed in the manner of a black hole, it could merge with another universe, just as black holes can merge. What would prevent a new expanding universe from swallowing the contents of an older, thermodynamically dying universe? It wouldn't be a merger of equals. It would, nonetheless, be a way for clouds of bacteria and viruses, all that might remain of life in our universe someday, to get close to some shining stars and viable planets and get life going again.
Of course, the actual mechanism whereby life might invade a new universe is unknown. But, as we have seen, the big bang theory is neither complete nor secure enough to rule out this possibility. Another reason to consider it is the biological evidence that life appears to require a means to have invaded this universe. This reasoning gives the evidence from biology as much weight as that from cosmology.
The conflict was analogous when the estimated age of planet Earth, calculated by Lord Kelvin in 1846, was a hundred million years, give or take a factor of three or four (10). Kelvin, the preeminent cosmologist of his day, based his estimate on the presumed heat of Earth at its formation, the net rate at which heat would be radiated away, and the current surface temperature. Darwin's early critics, Kelvin included, argued that this age was too young for evolution to accomplish all that it claimed. Darwin had no direct argument to use against Kelvin — only the biological evidence for evolution. So he ignored Kelvin's estimated age and continued to uphold his theory of evolution. In 1896, radioactivity, a crucial ingredient missing from Kelvin's formula, was discovered and Darwin's critics dropped the issue. Today there is abundant evidence that Earth is about 4.6 billion years old.
Because the standard one-time-only big bang theory is not firmly established, the thermodynamic entropy law cannot be invoked to keep life from lasting forever. What about the other problem — logical entropy?
The Logical End
In Cosmic Ancestry, life imposes organization on nonliving matter from the top down. Bacteria invade a lifeless planet and organize its environment. They're robots, genetically programmed to do a job. Later, new genetic programs within bacteria already, and new programs installed by viruses and other gene transfer mechanisms, become activated in the bacteria to enable eukaryotes and multicelled life to evolve. The progress of evolution depends on the availability of the genes necessary for each evolutionary step.
There may be a lot more potential in our genes than has been expressed so far. Looking at the accelerating curve of evolution up to now, we should not be surprised if evolution continues, producing even more highly organized forms of life. Evolution by the same process that has brought us this far could well take us even farther. And already, today, genetic engineering might enable us to augment the process. In the not-too-distant future, perhaps we could identify every working or workable gene in every creature that exists. If some creatures such as salamanders and lilies act as the stacks for the genetic library, maybe we could comprehend and catalog the stacks. Perhaps we could replicate genes never expressed before and install them into people or other creatures, to hasten life's evolution as far as the genetic potential allows.
We could have genetic potential equal to that of our Cosmic Ancestors. They would have made it available. Cosmic Ancestors would have envisioned, on other planets, "daughter" civilizations equal to their own. Why would they do less? Why wouldn't they try to enable their cosmic descendants to achieve the complete potential of life, whatever that is?
One troubling aspect of this picture should be addressed. By sending the genes in bacteria and viruses into deep space on comets with random trajectories, Cosmic Ancestors take the risk that some of the genes will be lost. Lots of the bacteria and viruses will fall into stars and burn. Most of them will drift forever in interstellar clouds or on comets that never come near any planet. So although a planet may come to life and start up the evolutionary ladder, it may not receive the entire set of genetic programs. The lack of an essential genetic program or group of programs might, for example, prevent the evolution of eukaryotes. The highest form of life on that planet would be scum, literally. Or mammals might never evolve. Admittedly there may be pathways besides mammals that can lead to a highly intelligent civilization. But whatever pathway were taken by life on any planet, its full potential would be that contained in the genetic instructions that ultimately became available on the planet. Perhaps we on Earth could "fill in" some simpler missing programs, such as the subroutines for pinstriped tulips, by writing them ourselves, if we wanted to. But no matter what level of civilization might be reached by a planet's life, it could not lift itself up by its bootstraps, so to speak, beyond the potential in its genes. That's not permitted by the law of logical entropy. Ultimately then, if something else does not extinguish us first, and if the traffic of comets to the inner solar system slows down to a trickle or a stop, the evolution of life on Earth should reach a limit. The limit would be no higher than that made available by our Cosmic Ancestors. And it could be lower, if some genetic instructions have been lost. Thus, the evolutionary potential of life on Earth could be equal to, or less than, but not greater than that of our Cosmic Ancestors. The logical entropy ratchet works only that way.
What if human society were able to coordinate itself in the manner of parallel computers? Could the power of that huge coordinated thinking machine increase without limit, just by adding more units? The problem is interesting. But in the philosophy expressed here, bootstrapping will never work, at any level. Probably, if we were missing a piece of genetic programming which is essential for some higher evolutionary step, we simply would never make that step.
It's worth wondering how plentiful in space the genetic programming for life might be. If it is very plentiful, then the failure of life on one planet to reach the full potential of Cosmic Ancestry would be a local tragedy, and nothing more. Life would surely carry on elsewhere.
But on Earth, if the programming for an evolutionary step in a higher direction were missing, how would we know it? Would we even be able to imagine it? Probably not. A city of prairie dogs could not imagine building steel high-rise buildings. Of course they couldn't. Hyenas can't imagine an armistice. How could we, after comprehending and utilizing every gene on Earth, know what higher potential, if any, were lacking?
Perhaps we could only know by an inarticulate gnawing feeling that something indefinable was missing. Or, if our scientific research stalled without enabling us to become Cosmic Ancestors ourselves, we might logically assume that something was missing. In either case, perhaps we would guess that there was a higher level of evolution available in the lost genes, somewhere out among the stars. A holy grail, a means of salvation, might be out there. Perhaps, driven by wordless longing or scientific faith, we would search for it.

NASA's Hubble Spots Rare Gravitational Arc from Distant, Hefty Galaxy Cluster, Space Telescope Science Institute, 26 Jun 2012. "According to a statistical analysis, arcs should be extremely rare at that distance. At that early epoch, the expectation is that there are not enough galaxies behind the cluster bright enough to be seen, even if they were 'lensed' or distorted by the cluster. The other problem is that galaxy clusters become less massive the farther back in time you go. So it's more difficult to find a cluster with enough mass to be a good lens for gravitationally bending the light from a distant galaxy."
