The giant accelerator would allow interstellar traveling


Kimmo Huosionmaa

The power source for interstellar traveling is the major problem in those futuristic spacecraft. If we are thinking about Warp-drive, what can travel faster than light, we must realize, that we would need the brand new technology, in the very giant scale. The spacecraft that would travel faster than light must be base the technology, what is ever created in the real life, and making this technology really is the very complicated process. The shape of the spacecraft would be like some science fiction spacecraft, what uses antimatter or WARP-propulsion for increasing the speed of 80-90 percent of the speed of light.


And in this spacecraft would be particle accelerator, what could be like the linear version of "Hedron", what is located in CERN. That accelerator would be like some extreme long tube at the nose of the spacecraft, what might be quite similar, what is planned to use in "Project Thor". The difference would be that the device is equipped with antimatter-motors, what will accelerate it for speed, what is near the speed of light, and then the accelerator would be launched. But the size of this spacecraft would be much bigger, what is planned for "Thor".


The interstellar spacecraft would first accelerate the top speed, what could be something like 90 percent of the speed of light, and the particle accelerator would shoot the capsule to the top speed. The problem of this hypothetical spacecraft would be the size of this thing. The accelerator must be over hundreds of kilometers long, and the electricity, what is used in this gigantic rail gun is very high. This spacecraft would be built in the space, and it would be very huge. If it sometimes would be made.


So there must be the very powerful power source, that this very huge spacecraft would be worked. And after the spacecraft have been shot by the railgun there is no return back. The capsule would fly to Alpha Centaur in about two years, but the problem is the slowing. And of course, the home trip would be difficult. In one scenario this spacecraft would use sophisticated artificial intelligence, and it would have sub-robots, what would build another accelerator at the orbiter of the target star.


This kind of artificial intelligence could also make the copy of the spacecraft if that is damaged. This technology is called "Von Neumann technology". In this case, those robots would search suitable materials from asteroids, what is orbiting the star by using laser-spectrometers. Then the materials would be transferred to the factory, and then those systems can create microchips and other stuff, what is needed for new spacecraft. This kind of systems can help us to colonize the entire galaxy in the distant future, but there are many technical problems to win before the trip to stars would be real.

MIT's tractor beam can make the new types of SASER systems possible

   "This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things.  That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

  "An illustration of NASA’s research plane ER-2 flying over thunderstorms. Credit: University of Bergen / Mount Visual (CC BY 4.0), edited" (ScitechDaily, Surprising Discovery: NASA’s Retrofitted U2 Spy Plane Reveals Tropical Lightning Storms Are Radioactive) The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries.  "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th
