Abiotic exponation- any explanation that doesn’t require life
Exoplanet- planet outside the solar system
Telescopes pick up light from these planets, we then analyse the light to see what elements/compounds make up their atmosphere. Say there’s a planet which has a noticeable increase in atmospheric carbon, the scientist in the meme is tempted to say it’s evidence of life (Forrest fire, industrialization, respiration), but it could be a geological process (volcanic eruption)
Please explain. I’m way too stupid.
Methane in Earth’s atmosphere mostly come from cow farts.
Methane in other atmospheres, as far as we know, doesn’t come from alien cow farts.
There’s a bunch of stuff that’s made by life, but it can also be made by not-life.
I believe the alien cow fart theory!
Burps primarily as far as the cows are concerned. Mostly just cow pies are coming out the other end.
