What If You Dive into a Liquid Methane Ocean?

A Weird Ocean Study

By Alex WilliamsPublished 3 years ago 3 min read

Hey there, and thank you for taking the time to journey through the word of science with me! Today I am writing about what is undoubtedly a fascinating topic - what would happen if you dive into a liquid methane ocean?!

Well, for starters, let's just say it's not going to be a pleasant experience. But let's dive into the details and see what we can find out!

Firstly, let's set the scene. Methane oceans are a reality on one of Saturn's moons, Titan. It's a fascinating place, not only because of the existence of these oceans but also because of the role they could play in the search for extraterrestrial life. But I digress; let's talk about what would happen if you break out your swimming trunks and dip your toes into one of these oceans.

Well, first of all, it's going to be a chilly experience. Liquid methane has a temperature of around minus 292 degrees Fahrenheit (-180 degrees Celsius). That's pretty cold, folks - and you may want to leave your swimsuit at home. In fact, you may want to wrap up in a thick thermal suit if you're planning to take the icy plunge.

Assuming you're all bundled up and ready to go, let's dive in and see what happens next.

Now, the most immediate problem you'd face is that liquid methane is much denser than the human body. So, as soon as you hit the surface, you'd sink - and fast. In fact, you'd sink so fast that you wouldn't even make a splash. Sorry adrenaline junkies, but no cannonballs allowed!

Once you're beneath the surface, things don't get much better. The extreme cold would instantly freeze any exposed skin, and the methane would start to dissolve in your bloodstream, leading to rapid hypothermia. You might be able to hold your breath for a few moments, but the extreme cold would cause your lungs to freeze up almost instantly. That's right - no underwater swimming or long breath-holding matches here. You'd be in serious trouble right from the get-go.

But suppose, somehow, you could survive long enough to explore the methane ocean's depths. In that case, you might discover some rather surprising facts. For starters, methane is a relatively good insulator, so the deeper you go, the less cold it becomes. In fact, near the ocean floor, the temperature might be relatively balmy - around minus 260 degrees Fahrenheit (-162 degrees Celsius). Hey, that's not quite room temperature, but it's still a significant improvement against those surface temperatures.

You might also find that it's quite dark down there; sunlight doesn't penetrate liquid methane very well, so you'd be faced with a murky, gloomy environment. But don't worry too much about being eaten by sea monsters; there's no evidence to suggest that life exists in these methane oceans just yet.

And that's about it - the end of our little adventure into the icy depths of a methane ocean. It's not a pleasant thought, but it's a fascinating one. Who knows - maybe someday, in the far distant future, humans will have the technology and know-how to explore these oceans in person. Until then, we'll just have to content ourselves with imagining what it might be like.

So there you have it, folks - what would happen if you dive into a liquid methane ocean. Spoiler alert: it's not a happy ending. But it's a fascinating topic to contemplate, and who knows where it might lead us in our search for extraterrestrial life. Thanks for reading!

    No Liquid methane is not much denser... in fact it is opposite. Liquid methane has only about 42% of the water or human body density at -162 °C (according to CRC Handbook of Chemistry and Physics (97th ed.). CRC Press. ISBN 9781498754293 or also here https://www.inchem.org/documents/icsc/icsc/eics0291.htm#:~:text=Density%20of%20the%20liquid%20at,risk%20of%20unconsciousness%20or%20death.). You would drop to bottom fast.
