Oxygen on planets

By Tirisilex, in Star Wars: Edge of the Empire RPG

Not that it's terribly important and I wont have it effect my games.. But how do they explain oxygen rich planets that are completely deserts or Tundra. Even Coruscant has no plant life so how do they get oxygen? I've always speculated that Coruscant has some kind of oxygenitic factories. Just throwing this out there.

Plot.

If you NEED an explanation, put them at the edge of the survivable zone of their star. Too close, total desert. Too far away, ice ball. Earth- like planet, right in the center.

As for Coruscant, I don't know of anything that says it NEVER had plant life. In fact, I believe that it was supposed to have been a native home to humans, which would necessitate plant life. Just, over time, Coruscant grew far too much for traditional farms or for any land to be left untouched.

one simple line of dialogue

'Oh thank god we made the THING DEVICE."

Coruscant has weather control stuff and all sorts of other devices. And some people have plants. I am sure there are hydroponic farms. Tatooine has some plant life. we just didn't really see much of it.

I don't understand your comment.

Basically (like with most sci-fi) the audience has to be willing to invest in the characters and story enough to not ask questions about how something can happen.

Its common in most media really at some point or another.

The hitchhiker's guide to the galaxy comes with the phrase "DON'T PANIC" written in large friendly letters.

And just in case a yellow fish will be jammed into your ear so you can make sense of nonsense.

These are ways of explaining that the improbable can be accomplished by simply enjoying the galaxy you are given to play in. If something doesn't make sense just remember people are wiggling their fingers making rocks float and shoot lightning from their fingers. It's sci-fi it doesn't have to make sense long as you are having a good time.

Also:

Getyo ass to mars!

Plants don't make oxygen from nothing. They break down Carbon Dioxide (CO2) keeping the Carbon © and freeing the Oxygen (O2). The Carbon Dioxide comes from a number of sources such as volcanos, forest fires and respiration of animal life. The point of this being Oxygen and Carbon Dioxide already exist. What you need is balance. If you introduce a massive animal population and no plants, you'll end up with low oxygen. Introduce massive plant population and no animals, you'll get high oxygen (but that will balance because you'll get lots of forest fires which release carbon back into the atmosphere).

So it's perfectly fine to have a desert world with little plant life if you also have little animal life. You just need to keep them in proportion.

There can also be oceans that are "out of shot" and these will take care of your problem too.

Now if you had a massively populous planet with no plant life like Coruscant and no oceans, then you need to start looking at technological solutions. But a planet like Coruscant already has those. Remember - the Oxygen isn't actually created by plants, it's just freed from water and carbon dioxide. You can substitute something technological to do that if you wish.

They don't, and there isn't one for what we see in Star Wars and sci fi in general. There are quite a few things that have to go 'right' for a terrestrial planet to even form and the 'all or nothing' worlds in sci fi with breathable atmo wouldn't really occur naturally. Best to just hand wave it and move along.

Turning CO2 into O2 is quite a trivial process easily done with machines.

As for other planets, like Tattooine. There are likely microscopic lifeforms that transform CO2 into O2. Algae is responsible for a ton of the Oxygen on Earth. No reason Tattooine can't have microorganisms living in the sand. Plus Tatooine doesn't have very many lifeforms to begin with. So no need for a bunch of oxygen.

An ice world would actually be even easier. There is already water, and there are forms of algae which can survive on ice and near freezing water. That would allow for a mono-climate(or something near one) to exist.

Soooo, you're saying Midichlorians are why people can breathe?

What are these miduiwhotzits you speak of?
