Title: What do you think of World Jump Day!?!?
Post by: harryneild on 03/04/2006 22:06:42: Hmm id like to see what you all think of this - http://worldjumpday.org/ (http://worldjumpday.org/)

I personally think that it won't work since the conservation of momentum means that all the downwards movement of the earth created by the jump will be opposed by the gravitational pull of all the jumping people. At least i think.

Also syncronising 600 million jumps all at once seems impossible.

Post by: harryneild on 04/04/2006 16:12:29: Yeh. I will be jumping too. I hope it doesn't have some bad effects though. Is this possible? Could it have a detrimental effect on the climate and enviroment??

What you do speaks so loudly that I cannot hear what you say.

Post by: another_someone on 05/04/2006 08:36:09: Well, if 6,000,000,000 all start jumping, one would expect an increase in the amount of dust generated (and commensurate increase in the erosion of the surface they are jumping on), as well as a slight increase in the amount of CO2 these people are exhaling, and an increase in the amount of heat they produce through their exertions. Beyond that, I cannot see it will any effect.
