deep questions
We would distort the Earths orbit, bringing doom to us all
Only if we all farted in the same direction, which is a level of collaboration I no longer know humanity to be capable of.
The PRC could pull it off, and i think 1.4 billion people simultaneously farting in the same direction would still be extremely powerful. But i doubt Xi would risk this, the US could easily mistake the giant BRAPPPPPP for the first impacts of a nuclear war.
What if..... We farted into a circle with a lot candle in the center? I'M ASKING THE REAL QUESTIONS HERE
among theoretical farticians, it is referred to as Exa-Beef, Class I event. while it's probability of occurrence during any 100,000 year period is negligible, I have been training for it since puberty.
the best advice I can give you is to keep your mouth closed as long as you can.
I don't think most people would even notice. Maybe those who were in a crowded area at the time. Earth's a big place, and humans are smol.
Now if by "we" you mean everything on the planet capable of farting? More might notice. I still don't think it'd even be enough to shake the ground or anything though.
If we were all standing on one side of the planet we could push earth out of it's orbit on a collision course with the sun. In a few short years earth would be unable to sustain life and the billion year long nightmare of existence would be over.
