What if the Earth would be a donut or cube?

What if the Earth would be a donut or cube?

This thing is interesting to think and when we are thinking about the possibility, that the natural planet would look like a donut, we must at first think that this thing is impossible. But then there is one small possibility that the planet would turn to donut-shaped, and that thing can happen when the planet, what is entirely melted, would start to rotate extremely fast, and then the thing like the material jet would go through it and form the planet to a donut. But I must say, that there is only an extremely small probability that this kind of thing would happen.

In this text, the fictional observer would stand on the outer layer of the donut-shaped planet. So this is not writing about Dyson's spheres or some hollow structure. The tale is about geometrical thought about the donut- and the cube-shaped planet, what is only exited in fiction. 

What if the planet would look like a donut?


And the natural planet cannot have a form of the box, because gravity would pull it to the form of the ball. Of course, in the future is possible that the humans or some humanoids would use extremely large lasers to form the planets, how they want. But as you know that making the planet-sized sculpture is difficult, because gravity has a very big effect on those sized particles. 

When we are thinking that the Earth-sized object would look like a donut, that would not affect creatures that are on the surface of that fictional particle. The most visible thing is that the horizon of the particle would be asymmetrical. On the other side, it would be really near the observer and another side it would be the farther. And inside the ring structure, the sky will be dominated a similar landscape, where the observer would stand. The horizon would be straight if it is near, but farther horizons are chamber heavily. 

And the gravity inside the wheel or donut would be stronger than the outer layer, and that means that the donut would not probably have an atmosphere. Or the atmosphere in the inner side would be tight, but also thicker than the outer layer. If we are thinking sharply the atmosphere can fly to space because of centrifugal forces. And centrifugal forces can destroy the entire donut-world. So this means that this kind of thing can be only fiction. 

But what if the planet would look like a cube? 

This kind of planet would not even exist, or it must not rotate at all, because centrifugal forces would destroy it immediately. But if somebody or something would be standing on the surface of that particle, the thing what that creature sees is the straight horizon, and when the creature would reach the horizon, there would be a very deep canyon. 

If the person just steps the wrong way, there is a possibility that the acceleration of falling speed causes that the creature would drop passing another layer and that means dropping to space. But the thing that happens is depending on the size of this fictional particle, and if the particle would have Earth-mass that character cannot slip to space. In this case, our main character would drop to the other layer when it goes back it sees that the layer, where that creature has just left is turned to the canyon. 

One thing that we can say is that the gravity would pull character to down, and that means that if our main character wants to make a parachute jump from the edge of that layer, that thing would fail because gravity would pull it to that layer. So the thing is that those very interesting looking fictional worlds are interesting objects to think about how the geometrical form affects the way how creatures will see things.

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...

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...

Who really was Plato, the great philosopher?

When we are thinking about the great philosopher Plato, we are thinking about the man who established the Academy of Athens. And we might remember that this man was a traveler. He traveled in many places in his life and wrote many texts and books, which still is very respected thoughts about the state and other things. When we are looking at the books or series of books, we are facing the thing, that there were lots of texts. If we want to use criticism we must notice that the model of the ideal state is rising the kings in the very high position, and the thing would flatter the kings. And sometimes I have thought that maybe that famous model of the ideal state is written by somebody else. The thing is that the model, where the philosophers rule the state behind the lines of soldiers could be written for the persons like Justinian, who was really flattered. The thing is that this kind of writings was meant for flatter the rulers, who would not persecute philosophers, even they had d...
