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.
