The folks behind World Jump Day are trying to shift the earth into a new orbit
the idea is that if 600 million people all jump at the same time will shift the earth into a different orbit and solve our warming problem.

website --->  http://worldjumpday.org/

they're going to do it on the 20 July

i signed up yonks ago

Surely, doing something at this scale could cause something quite horrific to happen:?

it's not going to affect anything, but hell i'll do it..

i swear i remember a thread about this from agers ago
Its probably been pruned now ¬¬
but it had someone (cookie i think) proving why it wouldn't work.

it is not going to work.

It probably centred on Newton's Third Law of Motion.

Lol, they say it will make it warmer on the arctic and colder in the desert, but making it warmer in the arctic will make the ice meld, and it will be the same if global warming happends

lol, make a anti-wjd website

Calling everybody on the eastern-hemisphere to counter jump

Hmm... for one thing, how's it gonna move? If it's all over the world, isn't everyone gonna counter-act each-others jumps on either side of the world? But yeah, it's just a stupid scam, probably to get emails or something. ¬¬ When a scientist proves to me it will solve global warming and will actually work... Maybe I'd believe it wasn't a scam.

jump for the world wouldve been better

Yeah they're in too broad of a space for it to work... We were talking about this in science class with newtons laws of motions... umm... yes you were probably right by saying the third one... ... It would be cool to do and for it to work.... but yeah... not going to happen lol.

what if we push it to far that we'll leave the orbit and go into outer space?

and it would be all the persons fault who made it up

Signed up for this last summer. Why do they need our emails, anyway? They can just count how many IP's have viewed the page.

What about the sun's great gravitational pull? We are so tiny in such a big world. Can it really make such a difference? Maybe, like three or so miles, yeah!

I don't mean to be so negative about it, but it seems very ridiculous. As Tasha said, it might just be some kind of scam unless scientific measurements prove more than just changing our planetary positioning would prevent global warming. After all, they didn't say it 'scientifically' would work.

it wont do anything, gravitational forces are huge.

that's stupid, i wont jump



i think it wont work

the h atom is the smallest one...
we would move less than half the diameter of an h atom

I would definately do it but then again, how will i remember the date? I sometimes remember my birthday when it's way past gone.

it sends u a reminder 1 day before if u check the box

it is not casualty, TD

they don't have enough persons...and i don't bellive that they are going to get 200.000.000 and more persons in seven months

We doesn't jump in Turkey.So we shouldn't not jump so much .Cuz we are already earthquake country But Im basketball player,Im everyday jumpin' to 3.15 meters 7/24

why do we need the whole world to jump surley hmmmmmmm i better not say that



its a good idea who comes up with these things?

i made a thread about this like a year ago and im sure someone else made one 2 years ago

but ya, impossible

Surely they wouldn't have wasted all the time and effort if it wasn't going to work?

This is so funny, I can't beleive they would actually try this...

if the whole world jumped at the same time, imagine the noise in a really populated city..

So...

If I want to "contribute", I have to jump at 4:39 in the morning?
This is the first time I think sleeping isn't useless.

And I was wondering why only people on the western hemisphere are allowed to jump.
Because they are stupid enough to get tricked?

If they actually put this thing into mass campaigns, get money to fund advertising the shit out of it, put more information up oh the pluses of actually doing it, they would get way more people doing this and could maybe make it work. Then again, that's if scientifically this is possible.

There are thousands and thousands of reasons why this will never work.

Simply the fact that specifying a time to jump is not nearly specific enough, even if you leave out all the physics, counter forces, etc, it will have absolutely no effect (not even a super-duper-micromillimeter) if people don't jump on the exact same time (and with time I mean measured in microseconds and less).

Also, people are not external forces. If you jump, you actually push into the earth with a (rediculus small) force. And after that it is only a matter of mass which object will attrack the other (human or earth) and will move back towards the other object due to gravity. Thus actually moving back in place as it was before...

To have a decent "effect" (again leaving out all the physics and stuff, thus assuming it would work, even by 1 millimeter), people should jump on the same spot, no spread all over the (western) earth.

If the earth is moved out of orbit and gets another orbit, global warming would be the least of our concearns.

etc... etc... you can go on for pages and pages why this is so absolutely rediculus...

I'm going to jump, but I'm sure it won't work(not only because you said so earlier in this thread)

lol didnt they do this before? im sure they did cos i jumped along with my school when a bell sounded at like 11am...

we got a longer break(recess) to jump too haha

whats wrong with that lol?

Nothing actually; it's great to have some pointless fun like this (especially when doing it with lots of people)...

Though, it would be a bit "wrong" if people actually believed they can make the world go into another orbit or believe the stuff about how it would change global warming etc...

Why do they say jump on a hard surface? It would matter if you were trying to smash something by jumping on it, but  jumping on any surface on Earth will have the same effect (not changing the orbit).

Yes, specially at a school.
