Anecdotally, I can personally attest that you will be propelled faster even in a gravitational environment such as here on Earth, especially if you fart near an outside influence (e.g., a person) while standing motionless. Their offense will often provide enough impetus for an opposite reaction; that is, a mighty shove.
related fact, because you can't burp in space (for a reason I don't remember, something about dissolved stomach gases maybe?) you fart a LOT more in zero gravity than you do on Earth.
I don’t think I could fart any more frequently. I might turn inside out.
You forced me to read this
So you can burp, and in some cases you have to, but it’s complicated. It also involves timing, which I’m not great at, so I’d have to do the other quite disgusting option (read the link)
Space smells like burnt steak… and digested steak.
Unless that outside influence is a certain type of freak, in which case you will paradoxically draw them closer to you.
Play Breathedge, that's actually a game mechanic.
If you fart hard enough it works in positive gravity too
Often that releases some ballast, which further decreases mass and potentially allows for more speed.
It does anyway, every action has an opposite and equal reaction
You know why you aren't falling through the floor? Cos the floor is pushing you upwards with exactly the same force that's pulling you down. It's not "the floor is in the way", the floor is actively repelling you.
Electromagnetism is cool like that
