Comments on: World Jump Day: hopping madness http://blogs.discovermagazine.com/badastronomy/2006/07/17/world-jump-day-hopping-madness/ I am an astronomer, writer, and skeptic.

It's not the people who are jumping on the Earth. The Earth is jumping on you. It will change your orbit around the Sun. In Soviet Russia,

You FOOLS! It’s not the people who are jumping on the Earth.

The Earth is jumping on you. It will change your orbit around the Sun.

How do you figure that it is worth twice the value of the other (opposite) ‘pushes’ as agreed happens in that jump? I modeled the two pushes from the jumper as equal, and thus the continued pull of gravity is twice either one. More accurately, the pull of gravity equals the sum of both pushes. icemith Said:

I dare say the artist involved (not worthy of repeating his name) knew damned well it was scientific bunk, that the momentum of the Erath through space would be unchanged. But in the realm of Performance Art, what a coup it would be if the artist actually got 600M people to all jump into the air at the same moment! In his mind it would stand as a momentary work of 'art' of some note. But realisticaly, it would never have worked except for a few college students who would have a laugh and another beer over their participation. No, I rather think this one creates a new category of 'art'. the Hypothetical Performance Art. It need never actually be done, it is enough merely to contemplate it. Ah, well, if ou ask me, the vaste majority of Performance Art should have been left as exactly that, thought. Jump Day had nothinbg to do with science at all.

What do you suppose the bandwidth cost would be to the owner of a site with that much traffic? A thought just occured to me: WJD says that over 6.0 x 10^8 people registered on the site.
