Snow Globes and Dyson's spheres

Snow Globes and Dyson's spheres

To this text is connected the image of the Snow Globe. Some inventors have created the idea to make the artificial gravity to spacecraft by using small bubbles, which are rotating the spacecraft on the top of the long tubes. In some drawings, those bubbles are looking like church bells, but as you know those things are the only hypothesis, that is made for theoretical purposes.

When we are thinking about the extreme long spaceflights the fresh food is one of the most complicated things, because it's hard to grow vegetables in the zero-gravity conditions. So the idea is to install two greenhouses to the body of spacecraft, and they can rotate it on the top of the long tubes.

If the greenhouse would be away from the crew cabins, that denies the danger, that some mushroom would start to expand in the cabin. And the things like hummus would not be released in the capsule, where the crew would stay, and destroy computers.

In the simplest model, those bubbles or greenhouses would be quite small, and they are operated by robots, and when the vegetables are ready to eat, they would put to the tube, and the crew can use them as the food. Those greenhouses can be connected to the spacecraft with the adapter, which is equipped with bearing and the tiny greenhouses are on both sides of the structure at the top of the tubes.

When the food would be delivered to the crew that would be made by packing to capsules, and then the system, what would act as a pressure air post would deliver that food straight to the cooker. If there are two greenhouses what size would be little bot bigger than Apollo-capsule, that would guarantee, that the food production can continue, even if the greenhouse would be damaged.

This thing has given the idea to some space scientists to create the small-size "Dyson's sphere" or the greenhouse to space. In this solution, the spacecraft would equip with two small greenhouses, where the crew can grow vegetables and other kinds of food. In some ideas, the little big bigger solution would be created by using Mylar bubble, and the bottom of the bubble has installed the tank of liquid hydrogen or the bubble would be protected against the solar wind or the particles, what is coming from the sun by using electromagnetic system, what is two masts, where are magnets. The mission of those magnets is to pull the ions away from the bubbles.

In some images to those bubbles has been drawn a house. And this might be the model of the spacecraft, which would travel inside the solar system. This thing would use nuclear power and gravity sling while it travels between planets. If the craft would use also gravity sling, that would save the fuel.

The researchers could live in that craft in the conditions, what seems like home, and artificial gravity makes possible to work on the surface of the planets and moons. Because there are at least two bubbles, there is a possibility to use another bubble in as the rescue room, if the micro meteors would break the cover of the craft. These kinds of visions are at the theoretical level, and they are not officially made in purpose. ¨

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
