What if we would want to establish the base on the surface of Mars or orbiting trajectory?

What if we would want to establish the base on the surface of Mars or orbiting trajectory?

Planet Mars seems an interesting place for the base, but the thing is that there are lots of problems with the long-term staying on that planet, and one of them is a weak gravity. As well as the strange space station concept, what is called "Solar Warden" has problems with the artificial gravity, because if we would think that those crews should someday return to Earth, the weak gravity in those stations would make the muscles of the crew members very weak.

So if the persons would want to live a long time in the space they would need so-called sumo-suits for keeping their muscles strong, and they should eat very much calcium for keeping their bones strong. This is the main problem in every simulation of the space station on another planet. And that kind of station is expensive operations. They should benefit the investors somehow, and that's why the artificial worlds, what was planned by Dr. Gerald O'Neill (1927-1991) in the 1970s are also a sophisticated solution for supporting the space industry.

But if the bones and muscles get weak, that thing means that the staff must be in that space station only short-term periods, but the problem is that there must need lots of people in those space stations. And traveling between Earth and those gigantic spacecraft would be expensive. So another solution would be that the crew just leaves to those space stations the rest of their life, and the third is creating artificial gravity what is strong enough that it allows a return to Earth.

Because of the gravity is too weak, the returning causes pain to those people. That's why this kind of thing must consider in the long-term space explorations. If we are planning the space station, what would make the artificial gravity by using the rotation movement, that thing would seem very effective and also very comfortable for making the artificial gravity field.

The thing, that would cause problems is that the rotation movement of the space station should be very high, because of the centrifugal force must be extremely high, that it can create artificial gravity. And in this situation, the rotation speed would rip the station in pieces, which might be one of the biggest hazards in the mission.

But there are some calculations, that the cylinder-shaped space station would reach the speed, what is high enough for causing a similar gravity with Earth, and that thing could be one of the most enormous machines, what human has ever created. If we are thinking that kind of artificial world, what could seem like some kind of city inside it, that thing could revolutionize the production in the space or zero atmospheric and zero-gravity space.

The zero-gravity factory would set in the middle of the cylinder, where are the zero-gravity conditions. And then the air inside the factory would be pumped out. That would create a vacuum inside it, and it can offer stable and balanced space for creating things, where is needed extremely high accuracy. This kind of artificial world can someday revolutionize the production of the materials and nanomachines. But creating this kind of station would be the long term process.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme.

The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
