The
Cosmic Landscape: String Theory and the Illusion of Intelligent Design –
Leonard Susskind (2008)
Having
read “The Black Hole Wars” I grabbed this other book by Leonard Susskind. This one deals with what seems on the surface
to be evidence of planned design, or an intelligent creator, but is really just
a result of ignorance on the part of those that see these things. He discussed how the very chaotic nature of
existence is hidden by the many examples of order and how this leads humans to
imagine that there is some sort of reason for everything existing, some sort of
guiding hand in the workings of nature.
Humans seek pattern in everything because that is how our brains are
wired.
Susskind uses the cutting edge of
theoretical physics to show the lie of the Anthropic Principle. In looking for the reasons why life exists,
or why the Universe is the way it is to allow life, some philosophers have
postulated the Anthropic Principle. This
states that the Universe is the way it is, and the laws of physics are what
they are, because they have to be that way to produce life. The reason we exist is because the Universe
was set up to have us exist. It goes
deeper than this simplified paraphrasing but it is a circular argument. It assumes that the reason the Universe is
as it is because it “had to” be that way
in order for us to exist and see the Universe for what it is.
Susskind shows how, using the
mathematical string theory of which he was one of the founders, the existence
of infinite universes seems likely. This
means our Universe is not special, or especially made to suit life, but that
instead we happen to live in the Universe where conditions for life are
favorable.
Countless other universes must exist
that do not have the proper conditions for cellular life, much less intelligent
multi-cellular life forms. It is a very
interesting idea and mathematically valid.
This brings to mind the contemplation of life on Earth. In our current knowledge of the Milky Way Galaxy, we estimate several billion stars, most of them having planets of some
sort. Let’s say that makes 200 billion
planets in our galaxy alone. The idea
that because Earth has life there must be life around many other stars is a statistical
fallacy. If you calculate even the most
generous odds against life forming on Earth, counting only the six or seven
most crucial aspects for life (such as the location of our solar system, the
type of star we circle around, the Earth’s Moon and it’s location in space, our
Earth’s axial tilt, etc.) the odds are quite staggering against life! Based on those odds it is likely that there may be only one in a billion
planets capable of making life. It is a
whole other level of intricacy to determine the odds that stability, time, not
to mention the risks of catastrophe, such as asteroid impacts, nearby
supernovae, and all other factors allowing cellular life to the billions of
years it took to evolve into intelligent, “conscious” life. It is quite likely that Earth is the single
planet in the Milky Way capable of harboring life.
The immense unlikelihood of our
existence is what feeds the Anthropic Principle. However, it is a very different thing to
state that, for example, a tongue can taste sugar because it evolved after
plants had created sweet fruit in order to better enjoy the fruit, than to say
fruit (which evolved hundreds of millions of years before our tongues) is sweet
because otherwise our tongues’ sugar-detecting capabilities would have nothing to
experience.
Dogs do not ask where ice cream and fruit come from! |
Religions use old variants on the
Anthropic Principle to push their lies.
They teach that the Universe is how it is because some gods/beings
created it for us. That is as selfish an
idea as humanity has ever come up with.
