Do we have the signals for intelligent aliens, but we cannot separate those signals from natural radio noise.

Officially SETI (Search for Extraterrestrial Intelligence)has no contact with aliens, so they cannot ask for help for breaking the signals of the aliens. That means there is no evidence that there is a captured signal from other civilizations in some hard disks. But nothing closes that possibility from the probabilities. There is a possibility that radio telescopes have captured the signal from other civilizations. But it has not separated from natural radio signals.

During SETI-program astronomers detected billions of signals and some of those signals might be from intelligent civilizations. And this is one of the biggest problems of the SETI-program. There might be signals, what source is the intelligent civilization, but then astronomers must separate those signals from natural radio signals. And then we must realize that the major problem with SETI-program is how to make that separation?

If we already have contact with alien species, the thing would go easily. We must just send a message and say: "would you please repeat your message"? But without contact, the separation of the signals is almost impossible. Even if we can separate the signal from the background radiation don't know the purpose of the signal. And in some jokes, the signal can come from the microwave oven of humanoids. So we would not make anything with that kind of signal.

If we want to crack the code, what the humanoid may use, we should know why the hypothetical civilization sent that signal? That thing would help the code breakers. If the code breaker would even know that the reason for sending the signal is some kind of repairment like the worker asks the drill the codebreaker would make the code-breaking by compiling the word "drill" with the captured marks. But in this case, the codebreaker knows the world "drill".

But even if we would capture the signal from another civilization, we must face the fact, that if we want to make the code-breaking and open that message, the codebreaker has nothing, what to use for making the matrix. The matrix is used to compile the density of letters with known languages, and that thing is impossible in the case of the alien signal.

The researcher has no dictionary book of humanoid language, not a single word, what can be used in that kind of operation. So that thing means that the process would be extremely difficult. Breaking code is a little bit more than just solving the numeric system or structure of bytes, which humanoids might use. Humans use a decimal system that bases the number 10 because we have ten fingers.

But the humanoids might have six or eight fingers, which means that in their decimal system 10 comes after the number six or eight. Or maybe they don't have number ten at all. Maybe those humanoids have the numeric system, which bases the almanac. That means they could have no stable numeric system.

There is a possibility that their numeric system depends on the number of moons or planets, what they are seeing. So that thing is also very important to find out, but another problem is the language. The researchers require the language that they can see what kind of data the signal involves. And without official contact, we cannot get the dictionary book of the aliens.

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...

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

. The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...
