Neil deGrasse Tyson |
As I was surfing the net for interesting intellectual fodder
I chanced upon the headline, “Neil deGrasse Tyson (Director of the Hayden
Planetarium at the Rose Center for Earth and Space in New York) thinks there’s
a very high chance the universe is just a simulation.” This caught my attention so I read the
article. It seems that every year a
group of high thinkers gather at the American Museum of Natural History for an
event named the Isaac Asimov Memorial
Debate. This year’s topic addressed
the question of whether or not the universe is a simulation. Ooh, heady stuff; maybe somebody should make
a movie about this! The panel was made
up of scientists and philosophers. The
article was rather skimpy on discussion details and was more or less a teaser
to introduce an attached YouTube video of the panel discussion. The video is two hours long. I lasted about twenty minutes. It was like watching the TV show The Big Bang Theory (CBS, Thursday 8:00)
without the jokes… and no Penny.
I like an intellectual challenge, as long as it doesn’t
require mathematics. And this seemed
like a topic I could have some fun with.
The question becomes, “Is our existence real, or are we merely features of
some other entity’s simulation?” More
about why the answer to that question renders the whole discussion moot a bit
later. But pretending now that we are
not smarter than a panel of physicists and philosophers let’s explore this hypothesis.
Rene Descartes |
We are all familiar with Descartes’ pronouncement of
existence, “I think therefore I am.”
While I am certain this statement has generated untold hours of discussion
among countless philosophers and pseudo intellectuals, it is plain enough on
the surface: My self-awareness is proof that I exist. I am okay with that. It would certainly be
difficult to assert my existence if I were not self-aware. And as a negative cannot be disproved, we
must allow our mere existence is not proof that our existence does not exclude our
non-existence. (How many times did you read the previous sentence before your
realized I was just screwing with your mind… or was I?). But
can we end it there?
Being sympathetic to lesser beings, I ponder the existence
of the common slug. Do you think that the
slug is self-aware? We can certainly
prove its existence by witnessing its presence in the physical world. I know, I encounter them every time it rains
and they are coaxed out of the flower beds onto my concrete driveway where they
die for lack of moisture. I am pretty
sure that this behavior demonstrates a lack of thinking ability; If they could think,
they wouldn’t expose themselves to such peril.
So I’m going out on a limb here and stating with whatever modicum of
intellectual authority I can muster, existence and awareness are not interdependent.
The debate is whether perception equals reality. Inspired by science fiction ala the Matrix, they want to explore the
likelihood that we are the creation of some superior intelligence that controls
how we perceive the universe. And that
the universe in which we actually live, generated in the imagination of its
creator, is different than that which we perceive. We (and our experiences) are merely thoughts
in someone else’s mind. Okay, here is
the shocker: A belief in a universe created by a superior being in which we
live at that being’s pleasure is… RELIGION!!!
Here is the hidden land mine that will explode this whole
discussion. What is, is.
It makes no difference the origin of our being. Whether we are the product of a computer
supported world or the creation of a spiritual deity, the operative word in all
cases is “is”. (Do you understand the
meaning of the word yet, Bill?) Perception
is reality. And if you doubt that, throw
yourself off of a one-hundred-foot-high building and see if you don’t start to
believe in the reality of your situation as you tally up the floors racing by.

I believe they have fallen into the same trap that our ancient
forbearers did. If we cannot distill our
understanding of what we see around us to absolute logic (experimental or
observational evidence… you know, scientific fact), we create myths to shed
light into the dark corners of uncertainty. At some future time, when
scientific understanding has resolved the mysteries beyond our current
comprehension of the physical world, they will look back at such debates about reality
versus perception with the same disdain with which we look at the superstitions
of our history.
