World Jump Day

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.

so you are saying that 30,000,000 ton (assuming the average person is 50kg each - very reasonable) of force on a portion of the earth is not going to do anything?

righto... fucken retards

Wow Logik! I didn't think any one could use such profound words like that. Good Job!

I believe that it would cause some type of vibration, or more. But it won't stop Global Warming.

geez, you guys suk if you think you can just jump on me and get away with it, i'll spew molten lava all ova yur asses

well the earth weighs
(5,972,000,000,000,000,000,000) metric tons

so if you think that the weight of all humans is significant think again its about
0,000000000004% of the earths mass...
Posted by Tore  on  Sun Mar 05, 2006  at  12:50 PM
I Think this will work.

600,000,000 x 50kg = 30,000,000,000kg (30,000,000 ton)

First the mass of the people is too little to influence the Orbit .
Second - mass doesn't matter - it's like lifting yourself by pulling your hair up .

this is gonna work, i mean come on, i weigh 400 lbs., if 600,000,000 people do it, itll move anything,
you guys are just trying to spoil the fun

How many millions of tons does the Earth weigh and how fast is it moving? This would be how many ton/miles? To do anything to Earth's rotation the number of ton/miles would have to be reasonably close to that number. And as far as stopping global warming, or creating a more homogenous climate how will people in the air - regardless of how many there are - do this? If I remember rightly, wasn't Hands Across America supposed to create world peace or some such? It is this sort of hoo-ha that discredits any investigation into alternatives that are in the least unconventional.

We're all gonna die! it doesn't matter! shame on those who rule the world with no respect for it. This is your penishment, upss punishment!!! JUMP! JUMP! JUMP!

um im not so smart actually im like 15 oh oh and i found out about this world jump day becouse our cience teacher told us about it and i was thinking if all those ppl jump wouldn't that cause an earthquake or tsunami or something that might get things even worse gulp i mean damn! and ive seen some many immature replys like " man this is gonna rock" oe something like that and i though poor loose what if we DIE?!! lol well not so bad like were gonna die but maybe something bad coudls happen confused

I think you should all just forget about it.

I think that it is going to throw the whole world out of orbit. Then you will be sorry. HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH.

its on my birthday n i cant wait ..hehe n wen u jump say hapopy birthday jarrod

Of course nothing will happen. Remember the Guinness toast? It was fun. So when the time comes, I am jumping... wot the hell.

500 million people jumping at the same time is no different than one guy jumping 500 million times, so get busy!

Unfortunately, the Earth is going to smak you in the ass as hard as you kicked it in the face. Result: nothing.

Pretending though... You would jump at noon and give a solid duck at midnight, do this every day. Though the duck doesn't seem as convincing, it's about as effective.

BUT!!! If we all (all Earthlings) sat down at the same moment, the Earth would rotate faster. If we cut down all the trees and knocked all the buildings down at the same time the Earth would spin even faster! ...shortening the day by at least .000000005 seconds!

If we all stretched as tall as we could we could slow it down too!

'nuff fun... I'm finishing up my perpetual motion machine.

Ok, this will only work if enough people do it, so if in the end it doesn't are we going to know if enough people did it? It will only work if we get enough people to do it, if something this big can work that would be amazing, i think it could very well screw up everything and maybe end the world, call my psycho but i think it's worth that chance,i don't know about any of you, but i'd rather die of an explosion or something rather than frying to death....

I find this rather amusing. You guys are arguing that this is a retarded idea. And you "spend quite some time" gathering scientific facts to try and prove it wrong. If this really was a retarded idea, which was already kind of a given, then why spend so much effort shooting down the idea? You guys are like the Christians. Never accepting shit that's slightly different from what you "know" is right.

What if we all walk opposite in to the direction of the earths orbit, would we stay younger?
Posted by anjie  in  greece  on  Tue Jul 11, 2006  at  10:31 AM
Let us think it's going to work, why are there always people there to try to look at the worst side of everything?
Posted by Sara  in  virginia, minnesota  on  Wed Jul 12, 2006  at  12:39 PM
haha, funny and strong arguments from both sides, but in reality, the magnitude of this jump will not change the earth's orbit...EVER...maybe just a little tickle...grin
Posted by Daivy  in  Riverknoll  on  Thu Jul 13, 2006  at  05:54 AM
I don't think this project is about changing Earth's orbit. I think this an attempt to reunite people all over the world so we understand that we're all the same and together we can try to make a difference. I don't think it'll change an inch of our orbit, but I'll jump to show my belieth that the world can be a better place
Posted by Henry  on  Sun Jul 16, 2006  at  07:33 PM
Hah! We couldn't even get Hands Across America to work, how do you expect to get everyone on the planet to jump at the exact same time? It's ludicrous to even consider it.
Posted by Charybdis  in  Hell  on  Mon Jul 17, 2006  at  09:36 AM
"OK, here are some quick calcs:

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
