This is a negligible impact compares to Earth's velocity around the sun. In other words, no measurable difference and that's being extremely generous having all humans located at the same place jumping at the same time to 2 meters high.

tl;dr: nothing would happen

nothing would happen to the earth's velocity or it's position in space or around the sun, yes
but I think it would be wrong to say nothing would happen.

some floors would probably collapse
some elevator cables would probably break
some people would die
that's already 300% of what you asked for
I could go on too

I still don't get the point of this meme. Yes I understand what it is from, but it's not funny. Why do you keep posting it?

sneed is a mid-to-high class level meme associated with Sneed's (formerly Chuck's) Feed & Seed.

To be frank I think it originated on [s4s], but I am not 100% sure.

So yeah, if you wanted to know what board controls the meme market you should gander over to >>>/s4s/
