US3 and a couple of questions
« on: June 24, 2012, 06:24:04 AM »
Will asteroid impacts, have an effect on a planets rotation and atmosphere
e.g. Atmosphere will be filled with dust and the sun will be blocked out, causing a mass extinction if the planet has life

Will we be able to customise a planet's Atmosphere
e.g.
45% Methane
25% Carbon Monoxide
15% Fluorine
10% Chlorine
5%   Neon

Mabey we could choose from a Periodic Table of Elements, and combine different gases and choose a percentage.

Lol, just realised that would be the worst place for life to exist, wouldn't want to travel to a planet with this Atmosphere :O

I doubt we will be able to customize the atmosphere to such an extent to determine what's in it, but we will have control of atmospheric variables.

what kind off variables?

reflectiveness and thickness i guess, we have slight functionality of that currently.

The atmosphere thing wouldn't be too difficult to implement, but what would setting the atmosphere to different gasses accomplish and how would it affect the simulation?

It would effect

- if life could exist there
- density would effect the impact force of a asteroid

Do you want a life simulator within Universe Sandbox or not? O_o

That atmosphere ain't gonna happen:

First of all, Chlorine and Fluorine are insanely reactive. Basically, they will vanish from a planetary atmosphere very quickly unless there's life producing them.

Neon can in principle remain in a planetary atmosphere and is fairly common in the universe, but it does not appear to exist in significant concentrations in most planetary atmospheres: http://en.wikipedia.org/wiki/Neon#Occurrence

So, you have a methane / carbon monoxide atmosphere. Your atmosphere contains no hydrogen or helium, so it must be either small enough or hot enough to not retain them. However, there's also no nitrogen, and any planet which lost its nitrogen would also lose its methane. Nitrogen also cannot freeze out at temperatures at which methane is liquid. Therefore, the nitrogen must be in some other form, such as ammonia and related compounds, which froze out. I may therefore conclude that your planet had a primordial atmosphere rich in hydrogen, which was later lost, and a surface temperature below 195 K.

You may also want to check how the chemical equilibrium works out for a mixture of CO2, CO, and CH4.

Kolwut, he was just providing an example.
