Global Warming - your chance to do something about it

[Jet-Lee]

what happens if you and your brother both punch a punching bag at the exact same same with the exact same amount of force on opposite sides? It doesn't move.

True, but the energy will be dissipated somewhere. Either by crushing the bag, building heat, or breaking someone's wrist.

how is that going to change the orbit of the earth?

Jet is right if anything, it's just going to cancel out and turn out to be nothing but a waste of a minute...

The point of my 2nd post is that it won't, really. The website suggests that if we all jump it would move the earth so that global warming would be lessened.

It just won't work, the earth is too heavy to be moved by the current population.

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.

Whoa I hate math and all of this lost me. Thank you for making me feel stupid.

Then lets start reproducing at a massive rate.

You forget that if all the people will jump several times (they still don't know it). Let's say that 600,000,000 people (where are all the Chinese people?) will move the Earth about a millimeter away. So what happens is that 1km=1000m=100,000cm=1,000,000mm So prepare for one of the best exercises for increasing your vertical leap.

But I've got another idea. What if we load all the Nuclear Weapons and bombs in the Western Hemisphere, evacuate to the South (Pole) and blow it up. It will certainly move the Earth a little bit. Only that the problem with the warming will not be solved...

[Jet-Lee]

if you move the earth farther out of it's elliptical orbit, it will pull in that much on the opposite side.

[Steel]

as yogs said, action-reaction. the earth wont even move that <1mm. It's the same idea as if you were to think taht putting a big fan on a sailboat pushing agasint the sail would actaully propel you anywhere.

[fredjacksonsan]

Yeah, but if you push off of a sailboat, the boat moves the opposite direction. Either that, or they're faking all those "World's Funniest Videos" videos.

It's just that the sailboat in question probably isn't large enough to have sufficient gravity to pull you back.

That's probably right, but we need to consult NASA....

Yeah, so doesn't that just mean warmer summers and colder winters, or vice-versa? I say we just get like a dozen big ass cranes to lift as much weight as possible and drop that at a certain time, but it still wont make a difference.

Lifting your own weight and dropping it on yourself....... that's like punching yourself in the face and expecting to send yourself flying into the wall behind you.

This shit wont work, people. Quit being stupid.

[YogsVR4]

Easy now. Nobody is being stupid. Everyones just having fun with a crazy idea on the web.
