Black holes in our solar system

 


Black holes in our solar system


Under this text is a link to an article that is published in the Business Insider magazine. There is writing about the possibility that we have a black hole in our solar system(1).  

There is one very interesting thing Could we have a black hole in our solar system? (2) Could this be possible? When we want to observe black holes, we must realize that we cannot get observations straight from the black hole. We see the disk of material around it, and here I must say, that we see only the radiation, what comes around the black hole. But inside the point, where escaping velocity would across the speed of light we cannot get the observation. 

And that means that we see black holes only when something drops inside them. So if the black hole is orbiting the star in the area, where is not material, that thing would cause that the radiation, what comes from the black hole would be very hard to notice. Or in other scenarios, the material that is dropped in the black hole is pure helium or hydrogen, because the black hole would act similar way with planets, and they will sweep other particles from their trajectory. 

That means that the light particles, that are dropped in the black hole would not send very strong radiation, which is hard to detect from the Earth, because it is sending in the form of X-ray frequency. That weak radiation would be lost in the background radiation. There have been speculations that near our solar system can be the very small black hole, what size would be about basketball. 

But what could form that kind of black hole? The answer would be that the antimatter explosion could form those really small black holes, which can exist about thousands or millions of years. Those periods are extremely short if we are thinking them at the point of view of the ages of stars like the sun. But even if those black holes would vaporize in a short period, that thing will take a very long time, if we compare that thing to the lifetime of a human. 

The vaporization time depends on the things, how much material the black hole can pull inside. And the stars would give the energy to those black holes, which means that the existing time of the small black holes is extremely hard to predict. The vaporization means that sometimes the black holes are losing photons, and what smaller the mass of this supermassive particle goes the loss of photons would increase. 

And sooner or later the black hole has finished its existence. When a black hole is in the space, the black holes cannot get anything to eat, and that means that they cannot get more energy. But if the black hole is near the star, that will feed it with energy, and that kind of thing can increase the lifetime of the black holes, which is extremely small.

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...
