Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

What if the earth ignites all the untapped fossil fuel and releases it into the atmosphere?
One hell of a show that’s for sure.
Maybe, maybe not. Fire triangle is heat, fuel, oxygen.
We can assume safely fuel and heat, oxygen is tricky though.
Explosions and ignitions only happen in a happy zone.
Too much or too little oxygen disables everything.
We also have to calculate what mix of hydrocarbons we are dealing with, how hot the ignition points are and the pressure exerted by gravity and the atmosphere.
I don't think there is enough oxygen.
Even under ideal circumstances and distribution, there is still only 21% oxygen in the air.
Propane needs 8x the amount of oxygen for a complete burn as acetylene does and acetylene in open air just produces thick greasy black strings in the air.
Idk the exact mix but I know you can barely hear acetylene coming out of a torch, but the oxygen side is loud as fuck.
Given a reasonable variance for imprecision, I feel the variance in sound levels is proportional to gas flow.
However depending on the pressure, you could need even more.
Diesel fuel is damn near impossible to light on fire at SPT, but put it under compression and it will self ignite.
We use turbos, basically little air compressors, to force as much regular air as possible into an engine, because it uses so much oxygen.
I guess that's all we could say
