The story of abilities of aerogel and nanomachines.

The story of abilities of aerogel and nanomachines. 

The lightest solid material on Earth is aerogel, which was invented in 1931. The material is very well known, and there is one question, and that is why Lawrence Livermore laboratories stamped this "solid smoke" top secret? There is one thing, what might answer that question. The thing is that aerogel is fibered silicon dioxide, and the version, what Lawrence Livermore laboratories created might base the carbon fiber.

Even if the aerogel is damaged, when it would be contacted with water, there are many usages for that kind of material. And the varnish or some polymer would keep the aerogel dry if that layer will repel water. And another version of that could be that the outer layer would use the nanotechnology, what is emulating the hair of otter, and that thing denies the water touch with aerogel.

The carbon-fiber structure would, in theory, give the carbon-based aerogel the quality, that the fibers operate like nanomachines. In this theoretical material, the carbon fibers could be like springs, what would remember their trajectory, if they will cut, and then those fibers can return to form. And this makes possible to create the layer, what fixes itself.

So the aerogel is a bright, light and flexible material, which is quite hard. There is one thing, what might make it interesting. That is the ability to use aerogel as the structure of aircraft and space vehicles.

The lightweight structure would make possible to send the heavier cargo to space. And if the aerogel can store information in the chemical computer program would that make a revolution in the material research and developing new kind of machines, what can change their form. 

The thing is that the DNA molecule would act as a chemical computer program. And if there would be multiple DNA molecules like tracks, the central computer of the craft can choose, what line would the enzyme choose, and that thing allows to choose the form of the craft. That thing would make possible to create a craft, which is like a living organism.

Or in some wildest theories, those carbon fibers could involve artificial DNA, which allows the craft to survive many situations. This kind of things are of course fully hypothetical versions of aerogel, and maybe they can be created sometimes in tomorrow. But if the layer of the spacecraft would be made by using artificial DNA, the craft can create a copy of itself.

The worst problems with long-term spaceflight are not technical

The worst problems with long-term spaceflight are not technical

In scientific and fictional books and writings and films, the problems of the long-term spaceflight have been mentioned the technical and physiological problems, like long-term staying in the zero-gravity would make muscles so weak that the astronauts cannot walk on the destiny, and that thing causes many dangerous visions.

What if they would be too weak to climb up the stairs with their spacesuits, or those suits would be too heavy anyway. The worst problems are social, and the biggest question is, what happens if somebody would get angry?

Or what if somebody gets hurt? What if some member of the crew is the wrong choice, and that member of the crew starts to cheat other members? When the spacecraft would travel between Earth and Mars, there is no way to take control of the situation, if somebody would start to act dangerously? What would those people do in that case?

There have been some horror stories, which are located in the space, and one of the most horrific scenarios is that, what if there would be a serial killer in the crew. In that case, the flight control must just decrease the gas pressure, that all the crew members would get unable to operate, and the craft would remote controlled back to Earth.

But there is another version of this kind of problem, and that is, what if some crew member would not dare to land to another planet? Or how the administration will recruit a member of the team, whoever lands to another planet? How to tell that person, that the role is vital, but there is no glory? That there would not any public question about that member of the team.

This kind of thoughts has raised in my mind one question about the social tests, what are made in the closed environment. That is "how realistic those experiments are in the real-life"? Would the test controllers tell those members of the test team, that their family members are dead if some kind of accident would happen? Or would the commanding team of the Mars-flight tell that thing to crew member, if that kind of sad thing will happen?

Computer researchers published a new algorithm that revolutionizes web management.

The new database structures require new and powerful tools to manage databases in non-centralized solutions. The new data structures can be ...
