But a short period on a geological scale, right?

hey /sci/entists, I was wondering about something.
Firstly, I'm not really well-learned on energy, so bear with me for a moment.
Energy, since it cannot be created or destroyed, is infinite. So the universe must be. Right?
But what if only potential energy is infinite, but kinetic is not? Can the universe still be finite?
I thought of this while reading about gyroscopes and thinking about the infinity of the universe. A gyroscope is made to spin (potentially) infinitely as long as the Earth is still spinning as well... that is, unless acted on by an outside force, i.e. stopping it with your hand.
So let's say, the (known) universe is (potentially) infinite, unless acted on by an outside force. I don't know what this force could possibly be, but just go with it.
Let's say this force happens, and the universe is stopped, or destroyed. There is still energy, of course, but the only energy left after everything is gone is potential energy. The potential to be infinite.
I probably sound crazy, but what do you think?
I figure the main argument against this is one energy can't exist without the other, but I was really wondering about this anyhow.

That's a great picture of Io; I hadn't seen anything from a flyover that close before.

Do you remember if that's Loki or just a random volcano?

Planet: Titan
Picture: Taken from the Cassini–Huygens spacecraft
Reason: It has water. It has an atmosphere. It's like a mini earth. There may be mini-humans there. Imagine fucking a 2 feet tall chick. Oh yeah!

Titan doesn't get enough love. Enceladus and Europa are great and all, but the potential for methane-based life is too strange and interesting to ignore.

>Titan, it is made out of oil!
that is how you get people interested in space travel.

Life on Titan

Y/N

Show your work.

SCIENTISTS have found evidence of life on Saturn's biggest moon Titan.
They discovered clues that primitive aliens are breathing its atmosphere and feeding on fuel at the surface.

Orbiting spacecraft Cassini probed the complex surface of Titan - the solar system's only moon known to have a dense atmosphere.

Organic chemicals, like methane, had already been detected on the 3,200-mile-wide moon.

Scientists expect life there to be methane-based - instead of water-based like human beings.

Research in science publication Icarus shows that hydrogen gas flowing down through Titan's atmosphere disappears at the surface - suggesting it could be being breathed by alien bugs.

Another paper in the Journal of Geophysical Research reports a lack of the acetylene on the surface, leading boffins to believe it may be being consumed as food.

The Open University's Prof John Zarnecki said: "We believe the chemistry is there for life to form. It just needs heat and warmth."


So what do you think of this?

1)How is it possible that moons can rotate in syncronization with the planet it is revolving around?
2)Do all moons do that? If not, just how common is it?
3)Does the rotation slow down over time? Or does it just start off like that?


Pic related, Titan also rotates in snync with Saturn.
