One technology, what will take humans to Alpha Centauri

One technology, what will take humans to Alpha Centauri

By using this kind of technology mankind can travel to Alpha Centauri in about eight years, but that thing needs enormous systems. And traveling to further the craft should be more sophisticated than this version. The problem with interstellar visions is to select a suitable star for the journey, and then choose the suitable techniques for the journey would take a long time. By using the next kind of complicated techniques the journey to the other solar systems would be possible, but the system allows to travel to Alpha Centauri, and further journey needs more sophisticated techniques. 

When we are thinking about the technologies, what can be used to travel in interstellar space, we must realize that the pure systems are not possible to make. The best possibility of that kind of journey would be hybrid technology. In that technology, the multiple systems would accelerate the spacecraft across space, and if we would need to make systems, what is giving the necessary punch for interstellar spacecraft, we must realize that those giant lasers and electron cannons are also weapons. And in the real-life interstellar space journey, there are many problems for solving, before the real craft would send to trip. 

One of the biggest problems is how to get the spacecraft, which would travel with very high speed out of solar systems across the Oort Cloud in one piece. And that thing is very complicated because of the size or weight of spacecraft would be about 20 tonnes, it would pull other objects to it at very high speed. And if the speed is about 20-50% of the speed of light, the impact with every particle would be devastating. One technology that allows interstellar space travel possible is the hybrid technology, where the spacecraft would push to the journey by using the giant electron cannon. 

This cannon could be the artificial neutron star or the giant generator, which will create an extremely high energy field by using plasma or ionized gas, which will rotate the stator of the generator. This technology, what is imitating things, what is happening inside planet Jupiter, would make possible to load the spacecraft with energy at the same time it would use its electron or WARP-systems. In this case, the electron cannon would push the craft forward for giving more punch to its motors, and when the spacecraft would be accelerated to the very high speed, it would start to push by using the laser.

The electron cannon would orbit the sun between the Earth and Mars, and when the craft has been traveled to cross the trajectory of Neptune, it would get more punch from the very high power lasers or radiowaves, what is sent by the nuclear-powered laser and maser systems. In this scenario, this is orbiting the sun outside the trajectory of Neptune, and when the speed would be near the speed of the light, the photon motor of the system would be started. If the speed is less than 95-99 percent of the speed of light there is no benefit for launching the photon rocket. And at that speed, the craft would not have time to break or give away in the front of particles, what can be the size of the sand crystal. 

If we would put the laser outside the Oort Cloud, what will happen in that case? The system would be enormous, the length of that hybrid system, what might be the free-electron laser would be even hundreds of kilometers. The nuclear power would make it very heavy, and in that case, the problem is to get this system behind the Oort Cloud. And it will pull meteorites and asteroids to it. When the spacecraft is flying the speed what is high enough, the system would turn to use laser, what would give a lighter punch, but the impulse of that thing is higher than use particles like electrons and protons, what will give more punch than photons, but those heavier particles are slower. 

So in some visions that enormous machine would use to clear the particles away from the route of the spacecraft by using laser- or maser radiation, what will destroy the "snowballs" away from the route of the spacecraft. And in this case, the thing is that the smallest particles, what are the most dangerous might be left behind.

Other civilizations and changing attitudes for things, what was self-evident in the past

Other civilizations and changing attitudes for things, what was self-evident in the past

When we are talking about things like other civilizations, we must go back to history and remember many TV-shows where the humanoids were some kind of joke. In that time there were no observations about other solar systems and in some popular scientific publications had the line that there would be no other solar systems and civilizations universe.

But as we know to develop the new type of telescopes what have new accuracy, there are observations about thousands of exoplanets. The last scientific news about the field of planet-hunting is the exoplanets, what are orbiting the Alpha Centauri, which makes possible that also double stars have planets. There are also remarkable observations about planets, what are orbiting stars, what is like the sun, but the observation of the multi-stellar system, what has planets are fascinating.

And when we are thinking about the forming of the planetary systems, we must realize that the brown dwarf can simply turn the planets to orbit it. In this kind of cases, the massive planet could have massive earth-size moons. But this is not writing about special cases, like planets that are orbiting the center star of the double-star system what members are far away from each other.

In that kind of cases, the planet could orbit between stars, and it might have life forms, what are active only a short period of the year of that planet. In this hypothetical case so-called open double-star systems where another member is in distance, what is the same, with a distance of Neptune, both stars might have own planetary system.

What if we would make contact with another civilization? Or rather saying, get signal from other civilization? First, we must understand that civilization could be very far away from us, and things like gravity lenses might focus that signal to our planet. That means that the signal would be visible only when the alien planet is in the right direction, which means that we could hear that signal only once.

So in those cases, we cannot even answer, if we want. And the second question is should we answer? If the aliens are hostile, we would be in big trouble. When we are facing another civilization, we must realize that the finding that thing would be the greatest scientific exploration, what we can think, and this kind of things are really difficult questions.

What we must do is to observe those signals, and then try to break their communications, and that thing is one of the most important things in the research. We should know exactly, who we would talk if we would someday answer. And before we would tell other people and the great audience about the aliens, we must say, that in that kind of cases, we would not need any kind of joke calls to those humanoids, or that thing could be really bad things.

So in this kind of things, we should hide the location of the star, where the signal has been coming. That would help the researchers to find out, what kind of thing is sending that message or signal. Here we must realize, that if the human race would someday receive the signal from another solar system, that would be the end of the era, that we would be only one intelligent civilization.

But the research of the possible extraterrestrial civilizations has been shown, how the attitudes are chancing also in the society, what is outside of the scientific community. The freedom of speaking about extraterrestrial civilization has been also symbolizing the changed attitudes, what science has been faced. There are many researches, which were not possible about ten to fifteen years ago, and one is the research about gender.

When I was young the gender was simply sex organs. That was enough, and until now we are faced that there are also other people than men and women, and that has been opened the eyes of the people, that the attitudes about the things, what were self-evidence are more complicated.
