About the movie "Independence Day" and high-power lasers


1) If the laser-ray would hit a tall building. the heat effect can cause an extremely powerful explosion.

Have you seen the movie "Independence Day", where the giant spaceships come from the universe and almost destroy our civilization? One of the most interesting things, that is in this movie is the laser-weapon, which destroys entire cities, and the thing is that those giant fictive spacecraft would need their size because that is suppressing the thermal effect of the powerful lasers. And if the size of those crafts would be too small, the lasers would melt them. 

The thing is that laser weapons would be most effective if it would be targeted in the tall building at the first. The high-power laser-ray causes extreme heat in those structures, and that thermal effect would blast the house. Then the energy, that is transmitted from that house, would cause the effect, which is similar to a dynamite stick or nuclear weapon. 

So the building would transmit the energy to sideways, and the thing that increases the effect would be the giant spacecraft, which is acting like floor above the area. This means that the spacecraft would aim the horizontal blast effect, which would be the most effective way to cause the area destruction because the blast would not have space to grow vertically. 

The only way, what the blast can get is the horizontal direction. And the blast would travel farther than the blast would happen under the sky. This has been caused the strange theories about obelisks. Obelisks are things, that might feel innocent, but if we would target the extremely high-temperature in those stones, that would cause the thermal expansion, what would act as the building in the "Independence Day" movie. 

2) If the temperature of the obelisk would rise to an extremely high level with extremely high speed that effect would terminate the entire city. And this is why extremely powerful lasers are dangerous. 

When the temperature of the stone would rise with extremely high speed to extremely high, that thing brakes the stone. The breaking stone would send the sound, and if the sunlight is warming that thing with very high speed, it would cause the expanding effect, what people can hear. So if the rise of temperature would be high enough the breaking stone would cause a similar effect with nuclear weapons. 

The speed of the sound or in this case the pressure-barrier is the same as the expanding stone. And is it possible that somebody has used those obelisks as the weapon? The thing is that energy could be pumped to the stone by using a large group of large parabolic mirrors. And if there is the structure above the obelisk, that would cause that the blast would be aimed horizontally. 

The modern version of this kind of thing could be the high-power laser ray, which is aimed at some building. Then the energy of the explosion would be transmitted to the structure, and that causes an extremely powerful effect. Of course, this kind of effect can be caused by using cathode rays, which causes a similar effect with laser, but could be more effective. In this case, the structure must load with opposite polar electricity, that the electrons would hit to the building.

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.

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...
