Programmed Reality

Last month, Lord Martin Rees, the president of Britain's Royal Society and "astronomer to the Queen of England", hosted the National Science Academy's first conference on the possibility of extraterrestrial life, which was attended by such scientific illuminaries as physicist Paul Davies, SETI founder and astrophysicist extraordinaire Frank Drake.  And the resulting sound bite of the week is "World-Leading Physicist Says 'They Could Exist in Forms We Can't Conceive'"?  

Really?  That's it?  That's news?  That's what we get from the world's leading thinkers on cosmology?

Sorry for my tone, but it's about time these guys got caught up with science fiction writers from 50 years ago.  Check out a 1959 movie called "Invisible Invaders."  Or at a minimum, take Carl Sagan's brainchild from the late 70's, "Contact" (film treatment in 1979, book in 1985, and movie in 1997) featuring a highly advanced extraterrestrial race who can appear to us in any form they want.  I'm sure there were many other writers who considered that a civilization advanced enough to cross millions of light years of space, might be advanced enough to learn how to cloak.  I certainly pondered that idea as a kid.  

No doubt, these guys are a bright bunch.  But not necessarily seeing the forest for the trees.  Take SETI, for example.

We tend to assign attributes of our own civilization and our own values to other potential civilizations.  But there is really no reason to assume that once life forms on a particular planet that it will evolve into a life form that is eager to communicate.  One could argue that the intelligence of dolphins, elephants, and humans are roughly equivalent (turn the clock back 50,000 years and look at what we assume about the behavior of each species; is there much difference?)  We don’t see dolphins building SETI dishes.  Using Drake's own equation for counting the number of ET civilizations that we might be able to communicate with, we need to consider the duration of a civilization communicating with electromagnetic radiation in the radio spectrum.  One can make the assumption that it might be similar to ours and in the range of 50-100 years.  But this is a big assumption.  Maybe ET modulates magnetic fields, or seismic waves, maybe they got fully wired for broadband internet before discovering radio wave propagation, maybe they communicate via telepathy, or entanglement, or some form of communication that is completely unknown to us.  Expecting them to have a period of radio wave technology that just happens to overlap ours is probably quite unlikely.  When I made reasonable assumptions for the factors in the Drake Equation in my book "The Universe - Solved!", I got the result of .08 overlapping radio wave civilizations per galaxy, making it unlikely that SETI will find anything before funding dries up.

On the other hand, modifying the Drake Equation to estimate the likelihood of ET visitation, I came to the following conclusion: If 50% of intelligent life forms can make it to Type III status, there should be thousands of migrating/colonizing/traveling species in our neighborhood.  On the other hand, would they even care about us?  When we take a walk through a field, do we attempt to communicate with the ants in an anthill?  If the field is ready to be leveled in order to make room for a housing development, do we attempt to save the ants?  No.  Why not?  Because they are so far beneath our intellect level or our perceived level of net worth, that such endeavors are simply not worth our time.  Now imagine what a Type II or III civilization might be like.  Consider how far we have progressed (some might say, regressed) as a society since the hunter/gatherer stage of human evolution 10,000 years ago.  Further, consider that we are accelerating in this progression exponentially.  So, for all practical purposes, it is impossible to even imagine where we might be in 10,000 years.  Telepathic communication, control of time and space, simultaneous access to parallel universes, full merge with AI?  Some futurists predict these things in hundreds of years, not 10,000.  Furthermore, since 100 million years represents less than 1% of the lifetime of our galaxy, it is not unrealistic to assume that Type III civilizations may be 100’s of millions of years advanced compared to our own society.  Given the foregoing discussion, it is easy to make an argument that it is highly unlikely that ETs are zipping about in our atmosphere in vehicles that appear to be no more than 50 years ahead of our technology (they supposedly crash, after all).  The only possible “True ET” explanation is that extremely advanced species either intentionally appear in a form that makes us realize that they are here (not unlike the father figure in the Carl Sagan movie “Contact”) or they don't appear to us at all.  The above section was taken from my book and written in 2007.

Lord Martin Rees, you should have saved yourself the expense of a conference and picked up a copy of "Contact" and "The Universe - Solved!"

This one felt really important during the height of the cold war.

All H-Bombs have an A-Bomb at their core.  The A-Bomb is needed to generated the million of degree temperature to begin the fusion reaction in the H-Bomb fuel.  So, all nukes, therefore, have at their core, a hunk of fissionable material, generally Uranium-235 or Plutonium-239.  U-235, for example, works well as a nuclear fission fuel because when the nucleus absorbs a neutron, it becomes unstable and splits into two smaller nuclei (e.g. Barium and Krypton), releasing more neutrons which then generate more reactions.  A critical mass of fissionable material will explode because the number of neutrons needed to maintain the reaction is exceeded by the number generated.  But, U-235 can also safely absorb a neutron and not undergo fission, transmuting in non-fissionable U-236 before further decay.  But if some process (for example, creating the perfect neutron energy) were to be discovered that caused absorption rather than fission, the core of the nuke could be neutralized.

So, my thought was to blanket the earth with a "rain" of the right particles to neutralize all nuke cores, regardless of where they are buried or hidden, thereby ending all fear of nuclear strikes.

My naivete may have been to think that we could generate enough particles at high enough density to neutralize a nuke core at any given point on the earth without having that particle beam have an adverse effect on plant and animal life.

So where are we today?  Actually, there are a number of nuclear remediation technologies (for example see Gary Vesperman's "Comparison of My List of 27 Methods of Neutralizing or Disposing of Radioactive Waste with PACE’s 9 Methods") that can clean up cores of nukes or fissionable material in general.  None can be accomplished on the "earth blanketing" scale that I envisioned.  However, maybe nanotech can come to the rescue.  Imagine a healthy swarm of nanobots, all carrying the materials needed for a nuclear remediation technique, such as RIPPLE Fission, and instructed to seek out all U-235 and P-239 and unleash the neutralization technique.  

Time frame?  I'm thinking...

When I was a geeky teenager, I remember dreaming up these wild inventions that I though could revolutionize the world in some way.  Since that was 30 years ago, I thought it might be kind of fun to take stock of the likelihood of these ideas it today's time.  Please try not to laugh.  Here was idea #1 - The Invisible Cloaking Device...

My thought was this - how cool would it be to be somewhere and put on a jacket and just become invisible.  Of course, the back pages of Popular Mechanics always had see-through glasses but of course, they were a gaff.  But I wondered if the cloaking concept could really work.  I didn't see why not.  The way I figured it, if they could make transistors that were pretty much microscopic, and LED's that were based on transistors, why not little cameras that were just as small?  All you had to do is put zillions of these cameras all over your cloak as well as zillions of LEDs.  But the LEDs had to be able to generate any color of light.  And each point of the cloak would have many cameras pointing in each direction, the signals of which were collected at a central computer.  The computer would figure out what part of the cloak was at the exact opposite position for each camera and each direction of view.  And so, that signal would get routed to the LED so as to generate the image that was the same as if you were looking through the cloak.  An engineering nightmare to be sure, especially in determining the position of every point of the coat. 

 

So imagine how excited I was in 2006 when I first heard of experiments being done with cloaking devices.  Unfortunately, however, the technology is still woefully weak.  As shown in the figure below, you have to put a camera directly behind the subject and a combiner device between the viewer and the subject and it only works in one direction.  So, nobody is going to get fooled any time soon.

But still, the resulting effect is kind of cool.  See below...

So when will we have true invisibility?  I have seen projections of 10-20 years for single color with a cloak of a well-defined shape.  "Sometime this century" for a Harry Potter type invisible cloak.  I think that nanotech will facilitate the process by enabling microscopic devices that can image in all directions and are self aware of their position.  So, I say...

I was reading an article the other day about a new theory on the reason that we sleep.  A UCLA researcher suggests that rather than provide some vital biological function, it appears that sleep evolved to conserve energy and "keep us out of trouble."  So it got me thinking about all of the other theories that I have read over the years - it helps restore energy levels, it strengthens the immune system, it repairs tissues and cells, it was an evolutionary development to avoid noctural predators.  And the list goes on, with no end of confusion and no apparent scientific consensus.

I wondered, what would be the purpose of sleep in a programmed reality?

And I thought of a possibility.  In multiplayer online games, a great deal of the logic behind the game resides in the client that sits on your PC.  The storage of the overall architecture of the game, each players attributes (to avoid hacking), etc., are on the server.  So what if our brain is analgous to such a client?  Doesn't the client need to be upgraded periodically?  Ever notice how most PCs and Macs do automatic upgrades to various client programs upon reset, or when you attempt to open the program after it has been closed?  Notice that these upgrades aren't done while you are playing or running the program?  The reason for that is to avoid any kind of software conflict.  It is far safer, and in most cases, essential, to do upgrades while the program is not running.  And then the next time you fire it up - presto, there are the changes.

Maybe the purpose of sleep is to allow the programmers the opportunity to upgrade our memories, processing capabilities, or whatever, during a down time.  It might explain why sleep deprivation causes us to act a little strangely.  It's kind of like trying to run an ancient version of Word on your new Vista laptop.  

(thanks to my nutty cat, Simba, for the sleeping pose)

This is a nod to the 30th anniversary of the release of the arcade video game Space Invaders, which came out in 1978.

Running on an Intel 8080 microprocessor at 2 MHz, it featured 64-bit characters on a 224 x 240 pixel 2-color screen.  There was, of course, was no mistaking anything in that game for reality.  One would never have nightmares about being abducted by a 64-bit Space Invader alien.  Fast forward 30 years and take a stroll through your local electronic superstore and what do you see on the screen?  Is that a football game or is it Madden NFL ’08?  Is that an Extreme Games telecast or are we looking at a PS3 or Wii version of the latest skateboarding or snowboarding game.  Is that movie featuring real actors or are they CG?  (After watching “Beowulf”, I confess that I had to ask my son, who is much more knowledgeable about such things, which parts were CG.)

Where will gaming be in the next 30 years?  For more on where that is going, feel free to check out my article "Is Our Reality just a Big Video Game".
