I think you (and Newton) are underestimating humanity as an individual force independent from the earth, its energy from human beings and energy from the earth. One person is insignificant but 600.000.000 its a huge mass hiting the earth... I belive it is possible :knock: but i´m not so sure about the consequences of such action and it´s ethical sense.

Fair enough. You are indeed entitled to your opinion, iven if it's one that isn't supported by the fundamental laws of physics.

laws are ment to be broken, don´t get so deep into what you read, free your mind and consider all the options :giddy:

If this were truly possible- seems like our rotational equilibrium would be wobbly due to the disproportionate number of bodies residing in China/India. Once this counterbalance reaches the inevitable stoppage of rotation, I just hope my side is facing the sun so I don't freeze to death. Also, toffeapple could put out his fires!

If this thing were truly scientifically possible, every government on earth would be hopping on it like jackrabbits (no pun inteded)
Surely the governments and NASA and every other kind of scientist on earth would be all over trying to figure out how such a move would effect everything from the moon's orbit, to tides, to weather, to seismic activity, etc etc etc...

Since no credible agency seems interrested, it must not be within the realm of possibility. But buy up the T-shirts before they are gone!

Spike is right, but he didn't use the KEY words: Centre of Mass. Gravity is a conservation force, true. What goes up must come down. Unless what goes up moves at 7 miles/second or faster (escape velocity of Earth).
What would happen if 600Meg ppl jumped all at the same time ( consider the technical diffuclties in the statement "all at the same time"), would be a : CentreofMass= (M1R1 +m2R2)/M1+m2, where M1=Earth mass ,
R1=Radius of Earth in meters. m2 =Total ppl mass (of 600Meg ppl), R2 =R1+jump height. (1 meter assume for simple calculation). Ok now we would expand the equation to get M1(R1+r1) and m2(R1+r2), where r2=jump height of 1meter and solve for r1.

simplifying the equation we get. r1=(m2Xr2)/M1, if r2=1m, then r1=m2/M1 or the ratio of jumpingpeople mass/Earth mass. r1 becomes indeed very small!!

What would happen is you'd get a wobble of whatever r1 works out to be during the jump. Then some minor decaying oscillation after the landing. Is 600 million enough, NO.
Edit : Sun_Jupiter Ex: put Sun in position 0, mass = 333,000 Earths. Jupiter in position 778,000,000 km, mass=318 Earths. Center of mass is 742,000 km from the Sun center, 96,000 km outside its surface. As Jupiter does its 11 year orbit, the Sun does a 1.5 million km orbit around the center of mass.

EDIT: I NEED TO GET OUT MORE puke:

Maybe you do, but thankyou anway lol

seriously though, someone needs to be interested enough in these things to spend the time with such posts. why not you? lol.

er...WHAT?

the earth simply has too much inertia (on account of it's mass) to be affected by humans jumping. i doubt there'e anything that we could do to alter the earth's position in it's orbit.

yeah very true.....but forget all that did someone say we Irish are like the germans??? did i hear that correctly?

frankly yiz have more chance of putting the earth on your back and jumping from planet to planet singing christmas carols than you have of getting an Irishman to admit he is like a german....not that theres anything wrong with being German there just NOthing like Irish people and I lived there for 4 months so im not stereotyping...

ok back to the physics.....as interesting as that is.....
