The folks at
World Jump Day plan to shift the orbit of planet Earth in order to
"stop global warming, extend daytime hours and create a more homogenous climate." They'll achieve this by having 600 million people jump up in the air at the same time on July 20, 2006. And they're looking for jumpers! This, of course, recalls the old idea that "If all Chinese jumped at once, cataclysm would result." This has been debunked by
The Straight Dope, which points out that the force generated by one billion Chinese people jumping up in the air at the same time would only be equivalent to about 500 tons of TNT. In other words, not that much. However, I don't think the creators of World Jump Day intend for anyone to take their idea that seriously. The site is registered to a German artist, Torsten Lauschmann. According to his
web bio Lauschmann:
celebrates glitches, and out-takes, bits in between and images that might be easy to ignore. Lauschmann is currently on a Trans European busking tour under the guise of Slender Whiteman where he will launch his solar powered dub system. He lives and works in Glasgow. Lauschmann also appears to be a member of a German art group called Vene Hammerschlag, which
has also hosted World Jump Day on its site. In other words, World Jump Day appears to be some kind of art project hoax.

Assume the average human can jump up by 30 centimeters (vertical shift of the center of mass). Also, assume the average human weighs 70kg. I'm going to ignore the 600 million figure from their website and substitute 6 billion (if everyone jumped), and assume that somehow, everyone jumped from the same side of the world. This means a total mass of jumping people of 4.20*10^11 kg. The earth has a mass of 5.98*10^24kg. So, the earth would move 7.02*10^-14 times as far as the people did. The people jumped 30 centimeters, so the earth would move 2.11*10^-14 m. The size of a proton is roughly 10^-15 m. So, the earth would move the equivalent distance of 20 protons. Not too encouraging...Also, once people were pulled back down by gravity, the earth would return to its previous position, resulting in a final displacement of zero."Cjl - BAUTF
Yup, 63 comments since March 1st last year. That's honestly not a huge response. It's just getting attention again because that time of year is rolling around and people are hearing of it and googling it.
Absolutely nothing, but they'll think they've done their bit, and happily go back to their usual lives. Sad, really.
Altering the earth's position could be catastrofic, it could change the natural balance of the waters, the ice...
Very bad idea. If something goes wrong, I will track them down!
hump day is freaking awesome
we should all hump each other
