For things that are "hmmm".
Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

So when you say "Autoignition", then ignition of what? For natural gas to "ignite", as in burn or in other words oxidize, there need to be an oxidizer present.
Autoignition here is referring to the temperature at which it will ignite immediately upon mixing with oxygen. Below that temperature, they can mix and not burn (like what happens with a gas leak).
