Under the Titan surface, water may not be water in the form as we know it.

"Titan’s hidden ocean may be more slush than sea, according to a new look at Cassini mission data. That icy, gooey interior could still host warm pockets of water—potential sweet spots for life." (ScitechDaily, Titan’s Hidden Ocean May Not Exist and That Changes Everything)

On the Titan’s surface, there is no water.  But. There are hydrocarbon oceans; otherwise, Titan is very dry. There is no water on its surface. The methane oceans are things that do not exist on Earth. But. It’s possible that under its surface is a water layer. 

Titan might not have a hidden ocean in the form we know oceans. This means that if there is some water layer deep under Titan’s surface, that water is in slushy form. The water deep under Titan’s surface would exist in extreme pressure but in low gravity. And that opens up new paths to consider possible alien life forms. 

There might not be fish swimming in that slushy ice layer. Maybe. There can be something. Called amino acids or self-replicating molecules. But then. We can think about things. Like. The existence of liquid water. Whether water is liquid on some planets. Or. Is it in icy form? That depends on things. 

Like. A planet’s temperature, gravity, and pressure. In strong gravity or pressure, water can be like ice. Even. If the temperature is high. Many variables affect water. And its form.

On a planet. Or, rather, we should say that the pressure, where water exists, determines whether it is liquid or not. In. Very low gravity or in magnetic fields. Water can be in liquid form. Even. At very low temperatures. In very low gravity and very low temperature.  

Tidal forces and magnetic fields can keep water in motion. So it cannot freeze. Otherwise, water vaporizes at lower temperatures. At low pressure. In low-pressure water, the boiling temperature is low. And that means. Water loses its ability to bind oxygen and other gases at low pressure. And that can deny the existence of life on some planets. 

It is possible. That. Water molecules turn in the same direction. This thing is possible. Because water is a polar molecule, and magnetic fields can turn it into N/S direction. So in a very stable. Low-energy. And a low-gravity environment. It is possible that a magnetic field can cause water flow on a low-gravity object’s surface. 

But the water itself doesn’t mean life. Another thing that should be possible. This is the amino acid reaction. At very low temperatures, some chemical reactions turn very slowly. 

Chemical reactions require energy, and that means amino acids cannot form in low temperatures. Or, that formation requires a very long time. The energy level must be right for the amino acid to form. Otherwise, chemical bonds require a certain energy level. And a certain chemical environment. Those life-building blocks don’t prove life itself. But they make life possible.

Cosmic mysteries and discoveries by using the most modern technology

Cosmic mysteries and discoveries by using the most modern technology

This is the writing about one of the biggest mystery of the universe, and that thing is the "big silence". Why does nobody answer to the radio signals, what SETI-program has been sent to the sky? When we are getting new and more powerful tools for discovering mysteries of the universe, we must realize, that in that work the old discoveries are replacing by the new mysteries.

And the thing is that every time, we think that we solve some problem, that problem changes its form. The term dark universe consists the dark matter, but also things that are invisible for us in space. And one of those things is the dark side of the moon.  How our moon can be so different on another side?

That thing is the same way fascinating as the quasars and extreme powerful radio bursts, what are making the universe more interesting than we are ever expected. When we are researching things like Moon, the difference between the side, what is to the Earth, and the side that is away from us is really interesting, because the Moon seems to be the wrong side to Earth.

If the meteors, what are pulled by the Earth to the Moon would come from the space, that will happen to another side of the Moon, but there are not "oceans" or magma plains. That means that the meteors or the forces, what were forming the "oceans" of the Moon would come from the Earth. There are meteorite craters also on the other side of the moon, and the theory is that is the side, what is turned to Earth faced impacts with a large number of small size meteorites, what was melting the basalt? Or was the reason for forming those oceans the ion eruption, what came from the Sun, and turned to the Moon from the Earth magnetic field, where those ions influenced like some ion cannons in the SciFi movies. That thing is a very big mystery but the solution would be that the Moon is turned to another direction. 

But when we are thinking that the things what we cannot observe would be the entirety, what we would call as "dark universe", because we cannot get observations from the objects, what are at the other side of the planets, or too far to see. That thing would be highlighted in the cases, where the people are hunting planets, what might be in the habitable zone.

The thing is that the star candidates, what would maintain the life, which is similar to us would be very bright, as I have written earlier. That means that we cannot get straight observation from those planets, and if the planetary system is inclined in the angle that planets would not travel over the star, that means that there are no changes in brightness of the star.

That means that we cannot get observations from those planets if we would search them. And as I have written before, there is a limited number of high power telescopes on Earth, and any of them cannot observe the single star years waiting that some planet is traveling across the star, and causing the change of brightness. This kind of things is very problematic.

And one thing, what we always forget, when we are thinking about the SETI-program is that even some aliens would have similar chemical structure, what we have, that doesn't mean that those aliens would be like we are or they would act like us. Sometimes we are facing many kinds of theories about why there has not been a single answer to the messages, what we have sent to space.

There is, of course, a possibility, that we have got messages, but we cannot open them. If those messages have made by using the quantum computer, we could not open them, even if we would know, that they are messages. There are also many other theories about the great silence, and one of them is that the Earth would be the cosmic zoo or some kind of experiment, how the species are forming and acting.

And that might feel a very uncomfortable thing. SETI program is the most fascinating and dangerous program in human history. The truth is that even if we would find alien civilization, we might not know, how to communicate with it. The messages what those aliens would make would have created by some other system than our binary numbers. In our computers has two sets in the binary numbers. The one and zero, and the last one means that there is no electricity in the wire.

But maybe those aliens would have computers, what has three or more rooms in the processors, and that means that those hypothetical processors would register many other voltages in the wires than the human-made microprocessors have. Maybe those microprocessors have nanotechnological sub-processors inside them, and those nano-processors would act like sub computers.

The problem with SETI-program is to recognize the synthetic messages, what might be done by using a different kind of technology or systems what we use.  And that means that we could not open the messages even we have recognized them. There are many mysteries in space, and one of the greatest is the "big silence". Why we haven't found other civilizations? Would we be so boring species, that nobody wants to make contact with us? Or is the numeric or coding system of the humanoids so different, that we cannot open those messages.
