There are two kinds of summoning, when you really get down to it. There's the summoning where the summoned wants to be summoned, and there is the summoning where the summoned is compelled to be summoned. Define your demon, and its behaviors, and you define how to summon it. It may want to be summoned, in which case this is extremely easy to explain. The ...

Well, we can't do it now so the only answer we have is 'more than we have now'. Alright, this isn't strictly true, insofar as we can cryogenically freeze embryos and the like, and we can then thaw them and bring them to term so depending on your definition of 'someone', arguably the minimum technology someone needs is the ability to create and maintain ...

A Programmed Feature: This idea is inspired by Willk's answer, though there have been other good ideas in the thread. It's a deliberate design choice by the long ago designers of the craft. Meant to help highlight and locate damaged components - the nanites activate a phosphorescent effect whenever chunks of the ship become separated from each other. ...

Daiquiri cryonics This is my favorite low tech method. Blood sugar and blood alcohol (and also acetone) are driven up in tandem. Way up. The person does not die of diabetic coma because her blood alcohol is so high, and does not die of alcohol poisoning because she is so cold that brain metabolism is slowed. You want the body no colder than the freezing ...

Let me be blunt A microscopic LED is entirely believable. I'd ignore all the explanations of why or why not and roll with the idea. Now the answer LEDs are diodes that emit light when they're in their operational state. Fundamentally, when you ignore the mechanics of miniturization (fabrication), your limitations are three-fold. First, even at magical ...

You need a trigger word. Right now, I can summon a big red round demon with the trigger phrase "hey Siri." My parents summon a materialistic demon with the trigger word "Alexa." Your demon bots (and nanites, etc) network with each other and if the summoning is done within earshot of any one of them, the message will go to the right demon who can respond, ...

Yes, it's possible to have LED displays with microscopic pixels. 3.74 μm qualifies as microscopic, I think. The JD4704 is currently the world’s first 0.7”, color sequential, 4K2K LCoS microdisplay comprised of over 10 million of the world’s smallest all-digital pixels, with a 3.74 x 3.74 μm pixel size. Order them from this company: https://www....

Interestingly, in unix land, we call any program running autonomously, a daemon. To interact with these daemon, one must know it's name, the commands available, the method of delivery of those commands, and the format of any data you wish to be processed. "Hey Siri, tell me tomorrow's weather at my location" sounds innocuous enough, but imagine if it still ...

Let's distinguish between nanomachines (which are self-contained structures on the nano scale) and nanodevices (which could be just parts in a larger machine). EMP weapons work by inducing damaging voltage in electric conductors. A nanomachine is very very small; let's say that the EMP comes with a humongous 100 kV/m. (For comparison, the insulating ability ...

Let's say LED stands for light emitting device. I'd go for phosphorescence. Basically, a photon is "captured" by an electron in the form of energy to be released later, as a photon with a frequency that is specific to the element. It occurs at subatomic level: you only need one atom for one frequency. If you want to have different colors and intensities, ...

See someone has already answered with nuclear decay... My answer is not actually based on science, so I know my answer will not be popular. This is more based on junk science and sci-fi concepts that we haven't yet mastered or even come close to. Quantum entanglement/FTL communication is the best I've come up with, and that's more sci-fi than regular ...

some sort of building blocks which are a few times larger than average molecules I'm not sure what an "average molecule" is, but water is about a quarter of a nanometre aross. A single keratin helix is about 45nm long. In any case, you're clearly talking about nanoscale mechanical devices here, so I'll just assume you mean "nanobot" or "nanomechanism". ...

The theory is that nanobots that destroy cancer cells could leave hunks of necrotic tissue in your body. Ideally, your body would re-absorb this and heal the wound over time, but this is not always viable. Stomach cancer for example can be difficult to treat right now because destroying the cancer risks leaving a hole that would spill bacteria and ...

Ok, assume you have wire that's a single atom wide. You have each atom bonded with only two atoms left and right of it. If these bonds are weaker than the bonds of the material you want to cut, well, there goes your wire. As such, no cutting steel with a 1D paper "blade". Next point is force. You need to supply forward force strong enough to move your "...

Change the premise a little, and you'll have a more interesting lore with more possibilities. Everything is better with nanites! Most of the inhabitants don't know it, but they can know it, because they have the same nanites in their bodies. Summoners, magicians, wizards, enchanters, witches, warlocks, alchemists, everyone is unwittingly a magical being. ...

Electroluminescence Short answer, the metal/alloy produces a high frequency low current EM field, and the voltage increases with more in proximity. The oxide layer produced by exposure to the atmosphere acts as an inorganic electroluminescent phosphor. The metal would be able to make other electroluminescent items glow as well. Long answer... ...

"Ship of Theseus" brain replacement (The details are here). If you have nanotechnology and picotechnology, you can work at a scale below glial cells and neurons. This allows to record and "decode" the operation of every single neuron, one a a time. Each new "nanoneuron" would interface with either existing biological neurons or other nanoneurons. A single ...

By design. A swarm of intelligent, interconnected nanomachines doesn't sound like a natural formation. Whoever designed and built them - whether that's the gods or R&D at ConGlomCo - quite sensibly put in a backup in case their normal methods of communications failed. This backup channel consists of a surface layer that reacts with certain organic ...

As Tim B pointed out it isn't technologically feasable yet to bring someone back from cryogenic sleep (sleep is a marketing euphemism since for all intents and purposes you are dead when frozen). As already said water needs to be removed due to it's freezing causing massive cell damage and other antifreeze fluids it could be replaced with will still cause a ...

It is alive. The pieces are calling to each other. its largest chunk begins glowing and doesn't stop glowing, sort of like a beacon for all its smaller pieces, which in turn glow brighter the closer they get to a larger chunk. These things want to be together. They are distressed to be apart. They are glowing because they are calling to each other....

BIggest problem with your question: "technology that works with sizes of less than 100 nanometres". That covers an awful lot of things, including the logic gates in the microprocessors that ultimately run the thing you used to post the question. Those nanoscale devices are obviously vulnerable to EMP, because they communicate with the outside world via ...

(~100 ug/m3). That is orders of magnitudes more than viruses (learn why), and orders of magnitude less than bacteria (learn why). Once a blood test gives a complete negative for bacteria, and given the absence of antibody markers for viruses in the blood serum, a doctor with access to an electron microscope will have the discovery of their life awaiting. ...

My answer is based on a previous answer which is about radiation. In my opinion that's exactly what you need. I thougth of Tritium which is usually used in watches to power the flourescent glow of the device. The problem is Tritium does not glow, it needs additional fluorescent material to do it, nor is it a metal. So I come up with two ideas: Should your ...

This sounds like Newtonian gravity, but restricted to this metal ‐ and not all the matter in the universe‐ and with glowing replacing acceleration. ...doesn't glow when it's in one piece Just like one piece of matter doesn't accelerates itself. ..its smaller pieces, which in turn glow brighter the closer they get to a larger chunk. ...

Picotech and Femtotech If you define the technologies available by the scale of engineering that is being supported, then of course the next stage involves Picotech: technology or set of technologies that rearranges matter on the picoscale with something analogous to nanotechnology's scope and precision. It would supposedly allow not only precision ...

How about MicroLEDs? They're brighter, faster and cheaper than OLEDs. Comparison LED vs. MicroLED, from digitaltrends.com I can't find any precise measurements though.

No. First off, there are no truly one dimensional structures, but if you assume there are: Cutting requires getting into the material and separating it. You need some sort of wedge for that, the tip digs into the material, and the flanks move the material apart. Sharpness only helps to some degree, it makes it easier to get some indent for the wedge to move ...

Just an idea for you to build off, or anyone else with more science knowledge. - A play off magnetic material - as magnets do seem to call to each other, but not visibly. But suppose you have a special alien space alloy, this alloy is composed with a super rare-earth magnet type material. The stronger this special magnetic field the more the components ...

Yes. But it’s going to take some backstory for me to explain. We don’t know the source of consciousness. There is a theory (based on data) that our brains have a quantum entanglement component that would make them un-copyable because you could never recreate the same entanglements. This theory says that once a mind is instantiated in any medium, that ...

Whatever your nanites are doing, it can be basically broken down to: take some molecules of A place them where they are supposed to be move the next molecule This means that the fundamentals of your process are not that different from a chemical reactions. Chemical reactions, if I remember my studies correctly, can be limited by: transport: if your ...
