Novacene: The Coming Age of Hyperintelligence
by James Lovelock
Published 27 Aug 2019

Perhaps because I was brought up as a Quaker, I do not have a literal view of religion – I accept much of its wisdom but not necessarily the truth of the stories. I now think that this religious view of humanity as chosen may express a deep truth about the cosmos. This thought was first inspired by a book published in 1986 entitled The Anthropic Cosmological Principle by two cosmologists, John Barrow and Frank Tipler. The first effect of Barrow and Tipler's book was to throw up fireworks of doubt in my mind about the scientific principle of cause and effect. Latterly I have realized that I have never really been a pure scientist, I have been an engineer.

We alone, among the billions of species that have benefited from the flood of energy from the Sun, are the ones who evolved with the ability to transmute the flood of photons into bits of information gathered in a way that empowers evolution. Our reward is the opportunity to understand something of the universe and ourselves. If the anthropic cosmological principle rules, as I think it may, then it seems that the prime objective is to convert all of matter and radiation into information. Thanks to the wonders of the age of fire, we have taken the first step. We now stand at a critical moment in this process, the moment when the Anthropocene gives way to the Novacene.

Must we fear the future and the surprises the Novacene might bring? I do not think so. This epoch will mark the end of what is to us nearly 4 billion years of biological life on this planet. As humans with emotions, surely it is something of which we should be proud as well as sad. If John Barrow and Frank Tipler (The Anthropic Cosmological Principle  ) are right and the universe exists to produce and sustain intelligent life, then we are playing a part like that of the photosynthesizers, organisms that set the scene for the next stage of evolution. The future is, for us, unknowable, as it always has been, even in an organic world. Cyborgs will conceive cyborgs.

Big Bang
by Simon Singh
Published 1 Jan 2004

But Einstein reduced his task to a manageable level by making a single simplifying assumption about the universe. Einstein’s assumption is known as the cosmological principle, which states that the universe is more or less the same everywhere. More specifically, the principle assumes that the universe is isotropic, which means that it looks the same in every direction—which certainly seems to be the case when astronomers stare into deep space. The cosmological principle also assumes that the universe is homogeneous, which means that the universe looks the same wherever you happen to be, which is another way of saying that the Earth does not occupy a special place in the universe.

In short, if the universe was infinite, then it could double in size and remain infinite and unchanged, as long as matter was created in between the galaxies, as shown in Figure 86. All cosmological thinking had previously been guided by the cosmological principle, which stated that our bit of the universe, the Milky Way and its environs, is essentially the same as anywhere else in the universe. In other words, we do not inhabit a special place in the universe. Einstein exploited this principle when he first applied general relativity to the whole universe. Gold, however, was going one step further and postulated the perfect cosmological principle: not only is our patch of the universe the same as any other patch, but our era in the universe is the same as any other era.

Stellar parallax is used in astronomy to measure the distance to the closest stars. parsec A unit of distance used in astronomy, equal to about 3.26 light years. Short for ‘parallax second’, it is the distance at which an object would show a stellar parallax of one arcsecond. A distance of 1 million parsecs is known as 1 megaparsec (Mpc). perfect cosmological principle An extension of the cosmological principle which states that the universe is not only homogeneous and isotropic, but also unchanging with time. This principle is the basis of the Steady State model. plasma A high-temperature state of matter in which atomic nuclei become separated from their electrons. primeval atom theory Georges Lemaître’s early version of the Big Bang model in which all the atoms in the universe were originally contained in one compact ‘primeval atom’.

He was just trying to figure out how the solar system worked. Only in the mid-twentieth century did it become common to draw an explicit analogy between Copernicus’s heliocentric solar system and later astronomical assumptions of an uncentered universe. Physicist Hermann Bondi used the term “Copernican Cosmological Principle” in a 1952 book. By the time of Gott’s 1969 visit to the Berlin Wall, it was natural (for an astrophysicist) to attach Copernicus’s name to a method with only a metaphoric connection to the Polish astronomer. One of those speaking at Kraków came to bury, not praise, Copernicus-as-metaphor.

From eternity to here: the quest for the ultimate theory of time
by Sean M. Carroll
Published 15 Jan 2010

The idea that matter is smooth on large scales can be elevated into the “Cosmological Principle”: There is no such thing as a special place in the universe. But it seems clear that there is a special time in the universe: the moment of the Big Bang. Some mid-century cosmologists found this stark distinction between smoothness in space and variety in time to be a serious shortcoming of the Big Bang model, so they set about developing an alternative. In 1948, three leading astrophysicists—Hermann Bondi, Thomas Gold, and Fred Hoyle—suggested the Steady State model of the universe.43 They based this model on the “Perfect Cosmological Principle”—there is no special place and no special time in the universe.

To Be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death
by Mark O'Connell
Published 28 Feb 2017

In high school he read scientific textbooks for pure diversion, and kept a scrapbook of equations he found especially stimulating; he was excited, he said, by the movement of the logic, the lockstep progression of the thought—by the abstract symbols themselves more than the actual things they signified. One especially rich source of such equations was a book called The Anthropic Cosmological Principle by John D. Barrow and Frank J. Tipler. At first, Anders read the book primarily for these tantalizing calculations—“weird formulas,” as he put it, “about things like electrons orbiting hydrogen atoms in higher dimensions”—but like a kid with a copy of Playboy who eventually turns his attention to a Nabokov story, he began to take an interest in the text that surrounded them.

Why People Believe Weird Things: Pseudoscience, Superstition, and Other Confusions of Our Time
by Michael Shermer
Published 1 Jan 1997

The Faith of a Physicist (1994) by the Cambridge University theoretical physicist turned Anglican priest, John Polkinghorne, argues that physics proves the Nicene Creed, which is based on a fourth-century formula of Christian faith. In 1995, physicist Paul Davies won the $1 million Templeton Prize for the advancement of religion, in part for his 1991 book, The Mind of God. The nod for the most serious attempts, however, has to go to John Barrow and Frank Tipler's 1986 Anthropic Cosmological Principle and Frank Tipler's 1994 The Physics of Immortality: Modern Cosmology, God and the Resurrection of the Dead. In the first book, the authors claim to prove that the universe was intelligently designed and thus there is an intelligent designer (God); in the second, Tipler hopes to convince readers that they and everyone else will be resurrected in the future by a supercomputer.

In 1976, Tipler began postdoctoral work at the University of California, Berkeley, where he met British cosmologist John Barrow, also a postdoc. Tipler and Barrow discussed a manuscript by Brandon Carter which described the Anthropic Principle. "We thought it would be a good idea to take the idea and expand it out. And that became the Anthropic Cosmological Principle. In our last chapter we combined the idea from Freeman Dyson [1979] of life going on forever, with physical reductionism and global general relativity; the Omega Point Theory then follows." Tipler's steps in reasoning sound logical, but his conclusions push the limits of science: I wanted our book to be completely general, so I said to myself, well, what about the flat universe and the closed universe [instead of an open universe]?

In Our Own Image: Savior or Destroyer? The History and Future of Artificial Intelligence
by George Zarkadakis
Published 7 Mar 2016

That intelligence cannot be a mere evolutionary accident that took place on a small blue planet on the outer ridges of an insignificant galaxy amongst the hundred billion galaxies that make up the observable universe. That intelligence is the pre-ordained seed of something bigger. But what could this be? In their book The Anthropic Cosmological Principle, Barrow and Tippler imagine a far distant future when the universe is slowly dying. This is happening because of a law in thermodynamics called entropy. This law states that heat flows from the hotter body to the cooler one – and you can test the law yourself anytime by wrapping your hands around a warm cup of tea.

Double Helix
by James D. Watson and Gunther S. Stent
Published 1 Jan 1968

Soon afterwards, however, the suspicion that the regularities were important clicked inside his head as the result of several conversations with the young theoretical chemist John Griffith. One occurred while they were drinking beer after an evening talk by the astronomer Tommy Gold on “the perfect cosmological principle.” Tommy’s facility for making a far-out idea seem plausible set Francis to wondering whether an argument could be made for a “perfect biological principle.” Knowing that Griffith was interested in theoretical schemes for gene replication, he popped out with the idea that the perfect biological principle was the self-replication of the gene—that is, the ability of a gene to be exactly copied when the chromosome number doubles during cell division.

Giving the Devil His Due: Reflections of a Scientific Humanist
by Michael Shermer
Published 8 Apr 2020

According to England’s Astronomer Royal Sir Martin Rees, there are at least six constituents that are necessary for “our emergence from a simple Big Bang,” including (1) Ω (omega), the amount of matter in the universe = 1: if Ω were greater than 1, it would have collapsed long ago, and, if Ω were less than 1, no galaxies would have formed. (2) ε (epsilon), how firmly atomic nuclei bind together = 0.007: if ε were even fractionally different, matter could not exist. (3) D, the number of dimensions in which we live = 3. (4) N, the ratio of the strength of electromagnetism to that of gravity = 1039: if N were smaller, the universe would be either too young or too small for life to form. (5) Q, the fabric of the universe = 1/100,000: if Q were smaller, the universe would be featureless, and, if Q were larger, the universe would be dominated by giant black holes. (6) λ (lambda), the cosmological constant, or “antigravity” force that is causing the universe to expand at an accelerating rate = 0.7: if λ were larger, it would have prevented stars and galaxies from forming.2 The most common reason invoked for our universe’s “fine-tuning” is the “anthropic principle,” most forcefully argued by the physicists John Barrow and Frank Tipler in their 1986 book The Anthropic Cosmological Principle: It is not only man that is adapted to the universe. The universe is adapted to man. Imagine a universe in which one or another of the fundamental dimensionless constants of physics is altered by a few percent one way or the other? Man could never come into being in such a universe. That is the central point of the anthropic principle.

Published 8 Sep 2020

Lawyers can’t do that because, though there might exist general guiding principles, human laws are ad hoc creations and cannot be derived from each other. Nor can doctors derive the details of human anatomy from any set of first principles. That the laws of physics can is a wonder that every physicist marvels over. Stephen studied those books and papers into which our knowledge of cosmological principles was condensed, and he learned fast. He expected to die in a few years, but at least in cosmology he would be spending his time addressing questions that excited him. * * * After they were married, on Bastille Day, 1965, Stephen and Jane rented a tiny old house at 11 Little St. Mary’s Lane, near the medieval church in old Cambridge it was named for.

Toast
by Stross, Charles
Published 1 Jan 2002

Ship of Fools dives headlong into the future and crashes messily up against January the First, 2000—hopefully with more grace than many of the consultants who were selling us all on doom and gloom back then. Toast takes Moore’s Law to its logical conclusion, while Antibodies cross-fertilises Vinge’s singularity with the anthropic cosmological principle and some of Moravec’s odder theories about quantum mechanics’ many universes hypothesis in an unsettling stew: but both these stories are brittle, subject to a resounding technological refutation that could happen at any moment. I wouldn’t bet on Dechlorinating the Moderator looking anything but quaint in a decade, either.

by John Brockman
Published 5 Oct 2015

After all, those microbes may still be closer to our present selves—representatives of life’s first generation rooted in the geochemistry of planet Earth. IF YOU CAN’T BEAT ’EM, JOIN ’EM FRANK TIPLER Professor of mathematical physics, Tulane University; coauthor (with John D. Barrow), The Anthropic Cosmological Principle; author, The Physics of Immortality The Earth is doomed. Astronomers have known for decades that the sun will one day engulf the Earth, destroying the entire biosphere—assuming that intelligent life has not left the Earth before this happens. Humans aren’t adapted to living away from the Earth; indeed, no carbon-based metazoan life-form is.

City: A Guidebook for the Urban Age
by P. D. Smith
Published 19 Jun 2012

Even in the earliest cities, greenery was used to soften the rectilinear forms of major structures. The ziggurat at Ur had trees on its upper terraces and King Nebuchadnezzar’s palace was greened by the famous Hanging Gardens of Babylon. Beijing has been an urban centre for far longer than London – some four thousand years. Chinese imperial cities were designed according to strict cosmological principles. From the first millennium bc, royal parks in Chinese cities were located to the north of the palace. The summer palace of Yuanmingyuan in the north-west of the city was begun in 1709 by Kangxi and expanded by subsequent emperors. It formed the largest royal garden in the world, with two hundred pavilions and temples set in an artificial landscape of lakes and gentle hills.

The Great Leveler: Violence and the History of Inequality From the Stone Age to the Twenty-First Century
by Walter Scheidel
Published 17 Jan 2017

Located at an altitude of almost 13,000 feet close to Lake Titicaca in the Andean altiplano, the city of Tiwanaku became the center of an empire that expanded from about 400 CE onward and lasted into the tenth century CE. In its mature imperial form, the capital had been carefully designed as an imposing ceremonial core, spatially aligned according to cosmological principles and surrounded by a huge moat that restricted access and that was meant to give the center the appearance of a sacred island. This enclosed area not only contained the state’s principal main ceremonial edifices but also accommodated numerous residences for rulers and the associated elite, and even grave sites.

The Singularity Is Near: When Humans Transcend Biology
by Ray Kurzweil
Published 14 Jul 2005

The anthropic principle comes up again in the context of contemporary cosmology theories that posit multiple universes (see notes 8 and 9, below), each with its own set of laws. Only in a universe in which the laws allowed thinking beings to exist could we be here asking these questions. One of the seminal texts in the discussion is John Barrow and Frank Tipler, The Anthropic Cosmological Principle (New York: Oxford University Press, 1988). See also Steven Weinberg, "A Designer Universe?" at http://www.physlink.coml Education/ essay_weinberg.cfm. 8. According to some cosmological theories, there were multiple big bangs, not one, leading to multiple universes (parallel multiverses or "bubbles").
