Global Warming - your chance to do something about it

Hahaha! Pretty interesting. How about a little math:

Jens Gundlach and Stephen Merkowitz from the University of Washington have found that the Earth
weighs in at 5.972 sextillion (5,972,000,000,000,000,000,000) metric tons
(credit:http://www.abc.net.au/science/news/stories/s122885.htm

Population of the World (2005) 6,462,392,746
From: http://www.census.gov/ipc/www/world.html

If we take the average weight of all humans on the planet to be 150lbs, this totals to: 484,679,455 tons. Say we triple that to reflect the impetus imparted by jumping. So now we have 1454038365 tons. Since 1 ton = 0.90718474 metric tons, we have 1319081416 metric tons.

So the weight of all people on the planet divided by the weight of the planet is the percentage or the earth's weight that all that jumping will move, or .00000000000022087(give or take).

The Earth's orbit stands at approximately 93,000,000 miles from the sun.

So, if everyone on the planet jumps at exactly the right time, theoretically the earth's orbit will change according to the percentage times current distance, or .00000000000022087 X 93,000,000 miles, or .0000205416 miles. That's .108459769 feet, or 1.3 inches. 3 cm.

So I don't think that they've done their math, or perhaps are overestimating the climatic change brought on by moving the earth (theoretically) 3cm further from the sun.

They also haven't taken into account how that would affect the moon, the international space station,

or, for that matter, Pam Anderson's breasts.

That is THE funniest shit ever!!

[YogsVR4]

That was great

[fredjacksonsan]

Heh heh thanks. But hmmm...after review I may have a flaw in my physics, but I'm sure someone will point it out.

Yeah you do!

Thanks. But I'm going on vacation now so hopefully it'll be fixed by the time I get back.....

[Zcaithaca]

someone e-pinch me

[bayouwolf]

The way I see it...Even IF they get enough people to do this it does'nt change the fact that the earth's core is LIQUID!
*****Conspiracy Theory Alert*****
Maybe this group is really a government entity in charge of getting the world wide obesity problem solved.
OR maybe it's just some grad students socialogy project. See how many idiots actually believe it will work because they have a fancy counter and some vague facts.

Hmmmmmmm........

[jcsaleen]

Lmao! I'm doing it!

[YogsVR4]

The only obvious thing I see missing is the force of the jump itself under the old 'action reaction'. Besides that, I'm to lazy to click on the calculator.

omg, lol, I am not gonna jump. I dont wanna be tha only retard jumpin out there.

[ThatRoundHeadedKid]

lol thats hilarious.

[Damien]

I'm jumping! What'll be funny is that if any of us actually see someone jumping, we know what it is for. Of course, we'll more than likely forget about this by next year.

-math correction-

OK, so since it's not the day I'm leaving on vacation anymore I've had time to reflect on the math. The force of everyone jumping is applied not to the distance from earth to sun, but rather to the weight of the earth to see how far it moves.

So in order to take the lbs-ft of energy, we'll say that everyone jumps 3' high. 150 lbs/person X the energy to jump 3ft X 6,462,392,746 (population) gives us 2.90808E+12 lb-ft (2,908,080,000,000) of energy.

When this amount of impetus is applied at precisely the correct angle to move the earth in the optimum direction (everyone's jump is perfect) then the earth will be moved according to the energy applied divided by the mass. So we have 2,908,080,000,000 units of energy applied to a mass of 5,972,000,000,000,000,000,000 metric tons. A quick conversion to English tons gives 6.583E+21
(6,583,000,000,000,000,000,000) tons. Units / Tons = # of feet the earth will move.

Calculating give us: .000000000486952 feet, .(something very small) inches. Less than a millimeter. Even less effective than the (incorrect) initial calculation.

Ah well, let's all jump. Maybe it'll cause earthquakes.
