A lone star travels at 1% of the speed of light.

 


The lone star CWISE J124909+362116.0 (or “J1249+36” for short) travels in the universe with extraordinary speed. This star may have been a member of the binary star system.  Astronomers suspect that the companion star in the system exploded as a supernova. This explosion drove the CWISE J124909+362116.0 to travel through the universe with extraordinary speed.  But that thing is not the only model, that could explain the fast-travelling star. 

Sometimes red dwarfs face the events that cause so-called super flare. Those superflares can act like rocket engines and change the red dwarf's trajectories. Also if the energy burst hits to star's atmosphere that can cause an energy impulse, that pushes the red dwarf into another trajectory. 

Red dwarfs are quite light objects and impacts with things like super Jupiters can also change a lonely red dwarf's trajectory. Cosmos is a strange place and there are lots of things that can affect red dwarfs. Things like gravity and other things are the things. That can cause upheavals, and destroy entire solar systems in less than a second.

This star tells us how dangerous the universe is. Maybe in the future, this kind of thing will travel into our solar system. And that could cause horrifying events in our solar system. We all heard rogue planets, that nova or supernova explosions threw away from their solar system. But that is the first time when the red dwarf star starts to travel around the universe. This star tells lots of things about cosmic eruptions. 

Things like radio, and other radiation bursts that hit stars or icy dwarf planets like Pluto can push those kinds of objects out of their trajectories. When a high-power energy burst hits the icy gas, it can vaporize the gas. That thing turns gas into the rocket engine, that pushes the dwarf planet out from its course. In the same way, high energy bursts like antimatter impact can cause asymmetry in the red dwarf's energy production.

Antigravity will be the greatest thing. That we have ever created.

"Artistic depiction of a fictional anti-gravity vehicle" (Wikipedia, Anti-gravity) Sometimes, if the airships have the same lifting power as the weight of the airship.  It can act like some “antigravity system”. Those systems are based on lighter-than-air gas or hot air. The system can have a helium tank. And the hot-air section whose temperature can be adjusted using microwaves or particles that lasers warm. Those systems are faster to control than some gas flames. This makes it possible. To adjust the lifting power.  If a thing like a balloon has the same lifting power as its weight, the balloon can be lifted to a certain point and altitude. And the balloon stands at that point until something moves it. That kind of thing can make an impression. On the antigravity systems. Modern airships. Like Lockheed-Martin P-791 can look. Like a “UFO”. The system can use systems to move the craft. Or maybe those ion systems are used for plasma stealth systems, if those airships' mis...

The first test flight of X-59 QueSST

The X-59 QueSST (Quiet Supersonic Technology) demonstrator is the next generation of aircraft design. The QueSST technology means. The aircraft creates a gentler sonic boom. Because its wings are radically long and narrow delta wings, and its nose is also radically long, which makes the sonic pressure cone thinner. That technology makes the sonic boom quieter.  The QueSST technology in X-59 is a new and radical design. All of those systems are caricatures. And the final solutions might look far different than the prototypes. The QueSST technology is one of the things. That is planned to be used. It is used in military and civil applications. If that technology is successful. It can be used in manned and unmanned systems. But that requires more work.  The X-59 also uses fundamental technology. Where the pilot must not have windows. To see outside. The camera and other sensors replace traditional windows. And that can be useful in more advanced aircraft that operate at hypersoni...

The theory about paralleled universes

http://crisisofdemocracticstates.blogspot.fi/p/the-theory-about-paralleled-universes.html Kimmo Huosionmaa There is the quite unknown theory about paralleled universes. In this theory, there is not a single universe. Universes are like pearls in the pearl necklace, and there could be the connection between those universes. The connection to other universes would make possible the channel what is forming when the black hole would make the gravity tunnel to another universe. And in the paralleled universe theory, there could be millions of universes in the line, and this is also known as "Multiverse-theory". This theory was established when the galaxy-groups were noticed by astronomers. In that time were noticed that there are so-called super-groups of the galaxy, and those super-groups, where we're so much galaxy that galaxy involved stars made some cosmologists think that maybe there is also groups of universes in the emptiness. This kind of structures is so enormo...
