Plasma cannons, Particle guns and Gauss rifles.

There are many weapons featured in science fiction other than the lasers that are beginning to get phased out as they become less “cool”. This article looks at some of the other commonly used options.

Plasma:


Plasma is the fourth state of matter, similar to gas and both extremely hot and ionized. The “plasma cannon/rifle” is a prevalent ranged energy weapon in sci-fi that throws either “bolts” or continuous streams of plasma that burn holes in enemies if not vaporize them entirely, unfortunately they have a tendency to overheat and explode.
Theoretically this could be done, we currently use plasma cutters to cut sheets of metal, but the jet extends less than a foot from the projector limiting its use as a weapon. We can see that there are some problems to work out.


With current technology air resistance stops the stream and makes a short blowtorch like flame. And even without air resistance (for example in vacuum) the plasma would dissipate into the surrounding environment within 50 centimeters of the aperture from thermal and/or electrical pressure expansion (blooming). This could be prevented by extending the magnetic bottle all the way to the target (nigh impossible), firing the plasma fast enough that blooming doesn’t occur (actually a particle beam), or using high-energy lasers to ionize the air around the stream (would only work in atmosphere).
Particle Beams:
Particle beams are streams of subatomic particles accelerated to near-light speed, striking the target’s atoms like billiard balls with a lot more kinetic energy. Aside from the problem of how large modern particle accelerators are…


…they would suffer from the same atmospheric resistance problems as plasma weapons and would most likely only be useable in space.
Electromagnetically Accelerated Projectiles:



Railguns and gauss/coilguns are similar to ordinary chemically propelled guns in that they launch a piece of metal at the target at high speeds. The difference is that instead of an explosion the projectile is propelled by electromagnetic forces and could potentially reach much greater speeds. These are becoming popular due to the fact that the military is actually testing them…

…and you can make your own from spare parts.

The only problems are that with current technology a handheld model takes a long time to build up a charge, what energy they do deliver is much less than a chemically propelled handgun and the navy’s experimental railguns intended for shipboard use tend to generate a plume of plasma from friction that wears out the barrel after only one or two shots.

Mind Reading Societies

This article also appeared in Science In My Fiction

A common characteristic of “advanced races” in science-fiction is the ability to communicate without using speech, gestures, or writing, but with their brains. Telepathy can be an inherent ability powered by “magic”, or it can be granted by implanted radios. Though one has to wonder what kind of effect this has on their society, specifically relating to their ability to keep secrets or to deceive one another.

Some say that relationships, and by extension civilizations, are founded on lies and held together by secrets. I expect that would be very hard if everyone could read everyone else’s minds. If such a society existed they would either have to be completely honest and keep no secrets from one another; or they’d make scanning another’s thoughts without permission a serious taboo or crime. In fact, one might expect a naturally telepathic species to be colonial organisms.

And as for collective consciousnesses, most portrayals involve each member broadcasting their every thought to everyone else in the collective, unless they’re all remotes controlled by the queen of course. This shouldn’t be a problem if they are all born into the hive like ants are, but if they were individually sapient beings (such as humans) who joined together as adults their individual pasts might come into conflict. If, for example, a married couple were to join such a group mind would it bring them closer, or tear them apart?

Some possibilities for writing:
• Humanity encounters a telepathic alien race that can only read each other’s minds, human brains are closed to them except through conventional communication. They have no concept of deception and cannot tell when humans are lying to them.
• In the near future brain-computer interfaces are ubiquitous and allow full thought-to-thought communication between two or more people. Someone develops a program similar to Twitter except that it posts thoughts instead of short texts.
• Software that allows constant mental communication between multiple people is developed and becomes the next big thing, followed by a surge of divorces and violent crime.

To all AI designers out there, program for compassion not empathy

Do you know, the difference between an Aspergarian and a psychopath? The answer is probably found in how they would respond to a Vioght-Kampf test from Blade Runner. "You are walking through the desert, you see a tortoise, you flip it over onto it's back..." An Aspie might state that they would flip the tortoise back over once it was obvious it couldn't do that itself; a psychopath would say the same, if they had figured it out, in reality they would most likely watch it bake in the sun. The difference is compassion, not empathy, the ability to gauge another's emotional responses is secondary to being able to "feel" for another.

I am stating this because some involved in the field of AI research have warned to beware of creating a superintelligence with "hyper-Asperger's". And I am worried that this may result in programmers designing an AI with a database of emotional responses and what usually triggers them, but forgetting to program actual compassion. So, at the very least we should prevent AIs from seeing Blade Runner and do a compassion test as well as the Turing test.

Aliens, psychology by diet

When we expand into outer space, we may contact other sapient species, and it can be guaranteed that they will think differently than us. But we may be able to predict their behavior by their diet. Something that Larry Niven touched on with the carnivorous Kzinti and the herbivorous Puppeteers.

Carnivores: The first thing you should remember is that predators are opportunists, they always take the route that is least expensive. If they get to colonizing other planets I would expect them to have the capability to adapt considering their need for complex ecosystems that would be a hassle to terraform from scratch. Due to their opportunistic natures I doubt that they might go to the trouble of eating other sapient species like us humans, though if there is a massive technological difference they might enslave or domesticate the less advanced species. Relations with humanity would probably be neutral or even allies, we might colonize and terraform dead worlds while they adapt to living ones.

Herbivores: To an herbivore, any other animal is a potential enemy, a predator or a competitor. I expect that their planets would be ecological disasters devoid of any other animal species except in the most extreme regions they never got around to colonizing. Since their supporting ecosystems would be comparatively simple they would probably terraform their colonies, because of that I expect that they would use a lot of weapons of mass destruction in inter-species wars. In addition the fact that extreme paranoia would have been a survival trait in their early history (more than humans anyway) would make diplomacy with them very difficult.

Omnivores: Would probably be closest to humans psychologically, as we are omnivores ourselves. Kind of a wild card, they might terraform, they might adapt, they might exterminate, they might enslave. They might even join forces with us and form the galactic federation. Fortunately trends on earth make it seem like most sapient species will be omnivorous.

Plants: I don't see any reason for plants to become sapient, but maybe a machine civilization would be similar. In short, they wouldn't care about consumers unless we got in their way.

Avatars and Surrogates: A new theme in Science-fiction?

Three movies this year involve technology that has been practically non-existent in Hollywood, teleoperation. First there was Gamer in September, where people were mind-controlled and used as players in video game like bloodsports. Then a couple weeks later came Surrogates, which was a more realistic portrayal of teleoperation, where people stayed at home and used remotely controlled "Surrogates" to live life. Next month is Avatar, about marines using genetically engineered "avatars" to conquer an alien planet. How did Hollywood learn about this?

My guess is the popularity of MMORG's, especially Second Life. Surrogates in particular seems to be referencing the internet. It could be a suggestion that people are increasingly trying to escape real life through the net, that would of course be the obvious one. Well, Gamer and Avatar are trying to emphasize the whole Humans are Bastards meme that is so popular now.

Why a Robot Revolution is unlikely to happen.

It is a common theme in Hollywood movies, robots rising against their masters and attempting to exterminate humanity. But why would we make laborers smart enough to rebel in the first place? Robots that are no-where near sentient are already used with great effectiveness in manufacturing, and both construction and agriculture make extensive use of machines that could easily be run on autopilot. The only jobs that sentience would be needed for in those fields are design and supervision, which would likely be filled by humans. Essentially the only things that near-sentient automatons could be used for would be personal assistants and millitary. Note that the robots designed for the purposes below could be bioroids instead of completely metal or plastic automatons if biological components turn out to be cheaper.

Japan is currently interested in humanoid robots mostly because of their lack of population growth, so that they can fill the gaps in their workforce caused by the aging population, and to help the increasing proportion of their population that is retired. Assisting an elderly or disabled person might require a significant amount of decision-making, but it is unlikely that human-level intelligence would be necessary. This would probably lead to android companions owned by perfectly healthy people and at least some would probably be Sexbots, so gynoids would probably be more common than androids. The problem is that there would be the potential for abuse of these androids and some manufacturers might make them more intelligent to seem more realistic. If abused androids were able to communicate with one another and able to feel pain they could organize and attempt to get back at their owners, possibly obtaining upgrades to make them more intelligent.

Military robots would be a far greater risk, combat situations often require more problem-solving ability than following a blueprint so robots designed for combat would either have intelligence compareable to a human or be remote controlled by human soldiers. It is inevitable that robots will be used for war as humans don't like to be killed, the problem is that if the robots are smart enough they might decide they don't like being destroyed either. For that reason it might be recommended that robots be designed with something like Isaac Asimov's three laws and only used for non-lethal force, and the only robots designed for lethal force would be teleoperated. I honestly wouldn't be surprised if human soldiers with cybernetic enhancements or power armor saw more use with the military than fully autonomous robots capable of lethal force.

Overall there is little threat of a robotic revolution due to the fact that there simply wouldn't be very many robots with the intelligence to rebel.

Uplift, Why Do it?

One idea that many transhumanists support is the idea of biological uplift, the possible modification of non-human animals so that they become at least as intelligent as humans. The concept was popularized, and named, by David Brin with his Uplift series of novels, where humanity has not only uplifted Dolphins and Chimpanzees but also discovered that almost every sapient species in the galaxy was uplifted by another species. Brin technically wasn't the first one to come up with the concept, H.G. Wells wrote about beasts vivisected to become men in The Island of Doctor Moreau back in the Victorian era (guess how it ended), in addition the hard sci-fi webcomics Freefall and Schlock Mercenary both involve characters that are genetically engineered animals and the Orion's Arm universe includes both provolves (they couldn't use Uplift for legal reasons) and splices. Now there are a number of transhumanists (such as Abolitionists) that think it is our moral duty to improve the quality of all sentient life, which includes most animals not just humans and maybe extraterrestrials.

But what they are not taking into account is whether animals would want to be uplifted, or even if humanity would have a practical reason to uplift others. Aside from attempting to colonize environments that humans couldn't survive in like in Freefall, I don't see much reason why anyone other than the military/police (and maybe Furry fans) would have a use for a talking animal. Maybe someone will think that society could benefit from having different points of view from multiple species or people will start wanting pets that can hold a conversation with them. But if you do think that non-humans should be uplifted to our level, you should consider whether a species would want to be uplifted. In some cases, such as great apes, it might be possible to simply ask a non-uplifted individual (using sign language or a computer) if they would like their kids to be able to talk like humans or be as smart as one. But for most other species it would be very difficult for them to understand the concept of intelligence and language, uplift would effectively create a completely different species so you might as well just uplift at least a few individuals and ask them what they think. So, if you think uplift sounds like a good idea, think it over a little more.

Some Options

After making two posts about my version of an Ideal Society, I suppose that the few people who actually read this deserve to know about a few of the alternatives.

The Collective ("We are the Borg"): A society consisting of a single entity that possesses multiple bodies, anywhere from a couple to several billion. This would probably be accomplished through the use of brain implants networked wirelessly so that they function as one. Alternatively the participants could be uploaded into cyberspace (see August 17th entry) and merge into one super-entity, with individuals serving as subroutines within the entity. The individuals within the collective may have varying degrees of individuality, from none to people that communicate telepathically. Does not particularly appeal to me.

Cyber-democracy: Back to the original democracy, aided by the Internet. Instead of electing representatives people who want to participate in government simply log in to a vast online forum and post their opinions. But seriously, who would have the time to read a thread millions of posts long, you'd need to have someone to manage the forum, or more likely a different person for each region, which would kind of reduce the forum to a massive electronic voting machine.

AIcracy: Artificial Intelligences will be superior to humans in every way, so why not let them rule over us and guide us to a Utopia. But why would they want to keep us alive, they could replace us with robots who could fill our functions in every way without complaining. Not to mention that even a self-evolving AI would be no better than its programmers or teachers. Regardless, this is the government typically used in Transhumanist sci-fi such as Iain Banks' Culture series and the Orion's Arm online worldbuilding project (even the Libertarian NoCoZo is subtly guided by The Invisible Hand of the Market).

Megacorp: The traditional government is weak or non-existent, instead immense, monopolistic, corporations control everything. These Megacorps might not be immensely corrupt and overall inhumane, but that works out so well now doesn't it. One should note that this sort of society is the setting for pretty much THE ENTIRE CYBERPUNK GENRE.

Techno-feudalism: Instead of advanced technology becoming available to everyone, only an elite class has access to it, either the scientists and engineers rule, or they serve the aristocracy as advisers or valued servants. In extreme cases the common folk might live in a pre-industrial state and be controlled through a state-sponsored religion that claims that technology is magic or divine. Alternatively the underclasses may be robots or genetically engineered to be of lower intelligence, while the elite are genetically enhanced or "pure" humans with no enhancements. Vaguely similar to the Galactic Empires featured in Isaac Asimov's Foundation, Frank Herbert's Dune, and the miniatures war game Warhammer 40,000, but of a much smaller size as FTL travel is physically impossible of course.

On Uploading one's Consciousness

Considering this week's episode of Stargate Atlantis I thought it would be appropriate to talk about one of the... strangest ideas of Transhumanism, Mind Uploading. Mind Uploading is the transference or copying of one's consciousness into a body other than that of the original, usually a computer or clone.

One might wonder why someone would give up their original body and become a machine, there are several reasons why. The most obvious of those is the near immortality allowed by having a body made of metal instead of flesh and bone plus being able to easily copy oneself in order to make backups or a distributed network brain, in addition the human brain only has enough available memory for maybe four centuries, while a computer can always have more memory added as needed. Also a computer program doesn't need any physical resources other than space to house the machine and electricity, anything else would be provided by a virtual reality. Finally an uploaded personality would be able to travel at the speed of light through data transmissions and experience life thousands of times faster than a humans.

There are several possible ways of Uploading memories, all of which are highly theoretical, and most of which involve copying the brain's structure and data (just to be clear, when information is uploaded or downloaded it's being copied, not really transferred). One such method would be to freeze the brain and cut it into "serial sections" to be scanned by an electron microscope so that the neural net may be recreated. Fortunately it may also be possible to use a highly advanced MRI or nanomachines to just read the information in a living brain without destroying it, of course this means that if the original was still alive then he/she would have a digital clone with the exact same memories and personality up to a certain point. These methods rely on pattern identity theory which assumes that if one has the same memories as a previously existing entity, then he/she is the same person.

Personally I think that if my brain was scanned and my neural network and memories recreated in a computer it would just be an AI that thought it was me and if my brain was taken apart and destroyed all at once then my personal perspective would end and I would die. However, there are two other hypothesized methods that would enable one to become a machine while retaining personal perspective. The first, and perhaps the most technologically feasible method of Uploading is cyborging, as parts of the brain are mapped and analyzed they are replaced with implants that mimic the functions of the replace parts, this method would take months or years to complete but the individual would retain their perspective during the process. The other method involves the use of nanomachines to replace the individual neurons in the brain one by one with artificial substitutes. If the technology becomes available in my lifetime I will probably have cybernetic enhancements done to my body if not my brain, but I would prefer to retain as many biological parts as possible for as long as possible. Maybe in a thousand years I will be distributed across several computer nodes and biological bodies scattered throughout the solar system.

My review of the Culture

I just finished reading Look to Windward by Iain M. Banks; it is part of a series about the Culture, a space-faring, post-scarcity, socio-anarchistic utopia watched over by immensely powerful AIs known as Minds that keep the biological inhabitants of their Orbitals or Ships safe and happy. Thanks to nanotechnology almost anything is available to anyone if they want it, most of the Culture's population lives in gigantic Orbitals that can house 50 billion people with room to spare, both of which make it so that no one has to compete with one another for living space or consumables, in fact most citizens simply spend their time playing extreme sports or some other activity they find entertaining instead of working. People don't even have to worry about dying as they can have backups of their consciousnesses made in case they die in a lava-rafting accident (though some choose to be "disposable" as a lifestyle choice).

Despite all of that the Culture isn't a perfect society by any means, for one thing they have an annoying tendency to interfere in the cultures of other societies that occasionally results in war. A major part of the plot of Look to Windward is a civil war that the Culture unintentionally started by attempting to dissolve the caste system on the planet Chel and the Chelgrian's attempt at reprisal by blowing up the Hub Mind of the Masaq Orbital and killing at least 5 billion of it's inhabitants. And after the attempt fails Special Circumstances sends a Terror Weapon (a shape-shifting nanoswarm with a sadistic personality) to gruesomely and publicly assassinate the Chelgrian leaders responsible. The Minds might not all be the benevolent overseers they seem to be, the Masaq Hub speculates that the Chelgrians may have been helped by a renegade group of Minds who believed the Culture had grown too complacent and decadent. In addition multiple alien races considered the Culture to be immature and impulsive, I personally think that the biological citizens are like spoiled children, they don't have to do anything and most contribute nothing to the Culture at all. Plus I doubt that there could truly be a post-scarcity society, even if one is able to transmute one element into another through nanotechnology there is a limited amount of matter and energy in the universe, I wouldn't be surprised if the Minds are secretly scheming to overthrow other cultures or to claim one another's resources (which for all we know could include citizens).
