Methane Definition and 109 Threads

Just wondering if anyone has an idea what the general consensus on abiogenic methane is at the moment. Just because they can produce it in the lab does that mean that it is definitely out there? Also how much of the methane in the Earth can now be attributed to this development process...

I need to read through this a few more times before I really "get it" but it will be of general interest. After one read-through, it looks like the effects of methane on climate have been underestimated in the past because this gas was measured in the atmosphere after it has mixed with other...

Howdy first post. Why is it said that life needs water to develop. Everybody says that life hear came from the sees but why could it come from a methane sea? or even beyond that on a gas planet? Thanks Ryan

Consider a high pressure gas cylinder of methane which exhibits a pressure of 200 atmosphers (absolute) at a temp. of 0*C in a small storage building. the building catches fire whcih causes the temp of the cylinder to rise to 1200*C. What would the pressure in the cylinder be then? express your...

Every time a measurement is made – the methane level rises. Most people on this Forum think I’m a loon. I’m a loon that gets it right an awful lot of the time; From the below Physics link; https://www.physicsforums.com/showthread.php?t=16799 Check wrote; “Anyone want to take a guess?”...

Vindication is mine, unbelievers! 10 years of screaming about Methane in the Martian Atmosphere! Well done Mars Express (you've released what NASA refused to with the Viking 2 Lander detection of Methane in the Martian atmosphere). Methane (on Mars) is a biologically-produced gas (despite...

Could it be...? :eek: http://news.bbc.co.uk/2/hi/science/nature/3577551.stm

Of course this will vary from person to person depending on various factors, but in general, how much methane gas is produced by digestion and where is it located? Is it possible for it to spread in the direction opposite of peristalysis(sp?). Also, is methane the only combustible gas produced...
