More about theoretical extraterrestrial lifeforms

More about theoretical extraterrestrial lifeforms

We must confess one thing, and that is we cannot know, what would some extraterrestrial lifeform look like. Because we don't have straight prove about the existence of that kind of lifeform. And if we are thinking about the fossils of planet Mars, we have not thought that they might become from Earth. 

When the giant meteorite hit Earth, that could throw water and other kinds of things even to space, and those ice bites can drop to Mars. But as you see this is one of many theories about this kind of thing. The life in the universe might be very common, but intelligent lifeforms might be a very extraordinary thing.

And the thing is that culture and technology are a little bit different thing than some kind of intelligence. This makes things like SETI-program so fascinating but in the same way so difficult. We don't know, what kind of things those organisms do, or what they are looking like, but as you see, we must say something. 

Those hypothetical organisms might live in different kind of conditions, and thing what is poisonous for us might be important to those aliens. If the conditions of the hypothetical planets would be similar to Earth, but there would be the giant landmass, there might live lifeforms, which cannot ever drink water. 

For those creatures, water can be poison, because it breaks the cells, and they can get all water from the food. In some other scenarios, aliens would live in the conditions, what is full of acid. In that case, those aliens might have slime cover, which isolates the body from the acid, or their skin would renew very fast because acid would remove cells away from the skin of those creatures.

 And for those organisms the conditions, where is no acid can be deadly, because the slime would sink that organism, or their skin would become too thick, what might cause death. Same way if the aliens would live in carbon dioxide, that means that pure oxygen would burn the mitochondria of those creatures. But those aliens are only hypotheses. 

Van Maanen's star and Epsilon Eridiani's connection with SETI-program. 

Van Maanen's star (Van Maanen 2) (1) is a white dwarf and one of the nearest stars of our solar system. The distance to that white dwarf is 13,9 light-years from us. The thing that the Sun would transform into a white dwarf at the end of its life has caused an idea that or theory, that this star might have civilization, what has moved to another solar system There is no proof about the civilization but the thing is that Van Maanen's star has once been giving fascinating ideas in the mind of SciFi writers and theorists, who have got idea, that this hypothetical civilization would move to Epsilon Eridani, before the Van Maanen's star has erupted as nova. But there is no proof about that. 

Epsilon Eridani is one of the stars, where is looked at the intelligent lifeforms. The star is very well-known because the OZMA-message (3) would send it to that star. This star is too young that scientists say that they could find intelligent lifeforms or civilization around it.  

And that star is only 0,7 mass of the mass of Sun. The thing is that Epsilon Eridani is cooler than our sun, and if there could be the aliens, they would not feel comfortable on Earth, because the sun is so bright, that the skin of aliens would burn. But there is one remarkable thing in that star and the solar wind of Epsilon Eridani is very strong, 30 times more powerful than the sun (4). That tells a very strong magnetic activity. Maybe it is caused that the star is very young, but there is another explanation for that. 

And that means that there have been happening something, what causes that effect. So is that star faced the GRB (Gamma Ray Burst), which means that it would get extra energy dose. That thing can cause that magnetic field would get stronger. But the energy for that thing might be caused by some other reasons and is it possible that the overactivity of Epsilon Eridani causes that the star has impacted with some red dwarf.

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...
