The good thing in the asteroid incident of last Thursday was that particle didn't hit to Earth

Last Thursday the asteroid, what size was about 45 meters passed the Earth from a very short distance. That distance was very close, and the small size of the asteroid made it very difficult to locate. And this kind of situations is really scary because of those small asteroids are the majority in our solar system. And the thing, what makes those asteroids dangerous, is that their trajectory can change very soon, and even the smallest stones can make them change their direction.

The destruction, what those very small asteroids can cause is quite small if we think only the destruction area, but if that asteroid drops to the populated city area like London, the number of casualties might be very high. And this makes those small particles scary. When we are thinking about the way to avoid impact, the safest method would be to turn those asteroids to another trajectory, and that seems a very good way.

But the problem is that if we would choose the wrong trajectory, that asteroid can hit to Ceres or some other big asteroid. Or it can start to travel with spiral trajectory, and in the worst case that trajectory would be the same with Earth, but in the opposite direction, and in that case the situation would be very dangerous. There is a possibility, that the asteroid would be closing Earth from the direction of Sun, it can come very close until it can be located. And in those cases, the nuclear explosion would be the only way to avoid impact.

The asteroid can shoot the kinetic energy warheads, what would break it to smaller particles, but if there would be the only couple of hours, the nuclear blast would be an only effective choice. The use of high-yield thermonuclear weapon could steam entire asteroid, but the EMP-pulse and radioactive fallout would be devastating. Another way to handle big asteroids is detonated series of small neutron bombs on the same side and point on the asteroid, and if there is water under the core, the steam can turn the trajectory to another way. 

Or that particle can be pushed by the rocket stage, what has feet on the nose, and that thrust can push the asteroid, what is about 500 meters away from the planet Earth. But the turning must begin early enough, that the rockets would affect. And if the speed of asteroid is too high, the pulling can happen too slow. The problem of that project is that Earth is quite a big particle and it can pull asteroid to the impact course, even the pushing would first seem effective.

If we would crush the asteroid by using nuclear weapons, the result could be that we would face the swarm of the meteors, what are the size of 50 meters, and we would not have time to locate every stone bite on that cloud. And when those particles will drop, the forests and cities start to burn. The result could be the nuclear winter, or global winter, where most parts of our ecosystem will suffer. And the new ice-age will be the thing, what mankind will face. Maybe the reason for the ice-ages were smaller meteorites, what hit on Earth.

Those meteorites were not so big, as the meteorite, what destroyed dinosaurs, but they caused the dropping of the global temperature. And when we are looking at the evidence of that catastrophe, the thing, what supports that theory are the puppies of Mammoths and other animals. A large number of very remains of very small animals, which are found from Northern Russia are telling, that the ice-ages were begun in the middle of the summer, and the temperature decreased very fast. And maybe in somewhere the meteorite hit on Earth, and caused that catastrophe.

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...
