The new evidence of the existence of Planet X

Planet X is never seen. That is one of the things that we should realize. Planet X is the mysterious gravitational effect at the edge of our solar system. The existence of that object is almost confirmed in one day. And some other day that strange thing doesn’t exist anymore. The thing that makes it very interesting is that the gravitational effect that makes Neptune’s trajectory wobble and the mysterious X-ray flares in Uranus are things that can cause many speculations. 

And one of them is that. There is a planet that is colder than the plasma around the sun. If the planet’s temperature is lower than the heliopause’s temperature and the planet’s trajectory is outside that point, this kind of object can be very hard to detect. The prediction is this, if Planet X really exists it would be geologically dead. It could be the rogue planet that our sun or the outer planets Neptune and Uranus are trapped near the edge of the solar system. It’s possible that this mysterious gravitational object has gone out from the solar system’s gravitational pool. And turned into a rogue planet.

The primordial black hole hypothesis. 

But there is also the possibility that Planet X is something like a black hole. In some scenarios, a very small black hole can pull a shell around it. In some models, the small black hole can exist in asteroid-size objects. Or even on some planets. The small black hole must only pull dust or ice around it symmetrically. If those particles are locked around that black hole they can form a structure that looks like a regular planet. So could some of the dwarf planets in the Kuiper belt be that mysterious Planet X? 

There is one object that can be interesting about the researchers. That object is the dwarf planet Quaoar. The thing that makes that dwarf planet very interesting is its ring system. That dwarf planet should have a very weak gravity. Sometimes astronomers and I thought that some kind of plasma whirling around that small dwarf planet makes the Van Allen-belt type magnetic phenomenon that can trap the low-energy plasma that comes from the sun. Another remarkable thing is that Quaoar has a moon called Weywot. And if that artist’s impression is right, that means that this moon is quite a long distance from Quaoar. 

The third interesting thing is that the Quaoar’s temperature is 41 K which is -231.3C. There is suspicion that some kind of radioactive process warms the Quaoar. But the primordial black hole can explain that temperature. 

But there is one very wild idea. Could Quaoar be the primordial black hole that formed the ice shell around it? Maybe that thing seems very rare, or radical theory. But if the planet X is some kind of primordial black hole, can that thing be some dwarf planet that we already know? That primordial black hole can seem very innocent if it's in some dwarf planet. And then we can look at another dwarf planet: Haumea. An interesting thing is that Haumea has two moons. 

When we look at images of Haumea we see that the little world with two moons is stretched. Haumea itself looks like an egg. That thing can happen because of the fast spin. Or it can happen because some force from that thing stretches the Haumea. Those two moons should destroy Haumea’s ring system. The names of those moons are Hiʻiaka (Haumea 1) and Namaka (Haumea 2)

The primordial black hole that is in the stable trajectory and pulls particle shells around it can be very hard to separate from the real dwarf planets. If there are no objects near that thing, we cannot measure the object’s mass using those things. If that black hole pulls all dust from around it. That thing prevents astronomers from seeing dust clouds from around it.

The water worlds are more common than we thought.

The water worlds are more common than we thought. So could the hypothetical planet X be the frozen zombie planet there are no internal nuclear reactions? There are plans to send a probe for searching that mysterious object which causes the errors in the trajectory of Neptune. Could that thing be the frozen water world there are no internal nuclear reactions? The thing that makes this hypothetical planet interesting is that it's invisible. 

Water worlds or planets that are covered by a water layer are more common than anybody expected. The water worlds can be planets there is liquid water. But there is also the possibility. That large-size objects are forming from ice. So in some theories, the mysterious "Planet X" is the frozen water world. In that case, hundreds of kilometers deep of ice can cover a large part of that planet. 

But in the case of "Planet X," we should talk rather about the "gravitational effect X" than some planets. One of the explanations why we cannot see hypothetical "planet X" is that the planet is so old that in its nucleus is no radioactive material left. And its nucleus is turning cold. In that case, the planet will not send its radiation at all. That means it's impossible to detect by using infrared. 

But when we are thinking about the water worlds there is one thing that can make them hard to detect. Water has one quantum state that we don't remember. That molecule is polar. So that means if the planet's magnetic field is very strong. It can turn water molecules in the same way. 

Two things can keep water liquid on hot planets. The first thing is gravitation. In an exoplanet, Gliese 436 gravitation causes the ice core covers the entire planet. Which surface temperature is over 400 degrees Celsius. And the second thing is the strong magnetic field. The strong magnetic field can also deny water vaporization. 

A strong magnetic- or gravitational field can turn the entire planet superconducting. That means the magnetic or gravitational field can remove oscillation from the minerals and other materials. And that thing turns planet superconducting. In that case, radiowaves can travel through this planet. 

The thing that can make the planet invisible is (almost) 100% reflection. There is a possibility that a certain level of radiation reflection creates a shockwave or standing wave above the layer. In that case, the standing wave motion will drive a large part of incoming radiation through that planet. And that thing makes it harder to detect. 

In that case, reflection impacts incoming radiation with the same power. Or the material will pull most of the radiation in it. And in that case, there is a possibility that the outcoming radiation pushes reflection back on that planet. We must remember that things like hypothetical "planet X" are extremely cold objects.  

And in that case, the oxygen or hydrogen atoms can turn outside. This thing forms a magnetic monopole. If the water is in the direction where all molecules are in the same direction it can turn the object hard to detect. In that case, there is no other emission than oxygen or hydrogen. 

If the temperature of the planet is extremely low. That planet turns into a superconductor. The superconducting planet could let radio waves travel through it. And in another case, the strong gravitational field can turn the planet superconducting. Superconduction means that the atoms or molecules are locked and their oscillation is removed. 

Normally researchers make that thing by decreasing the temperature. But also strong gravitation or a strong magnetic field can turn planet superconducting.
