World Jump Day

don't jolt- add spin!

What if all 6 billion of us just gathered up in, say, the far east of Siberia. The combined mass in one spot would surely increase the planets' speed of rotation; then combined with the massive shivering effect, the already slight axial tilt would increase to the point that THE SUN WOULD RISE IN THE NORTH!! Every 18.4 hrs. (my math on that is a little fuzzy- not everyone weighs the same) What a wonderfully calamitous event. Perhaps if it were organized in time, it would make for a truly NEW year!



witless is bliss
 
What if all 6 billion of us ran in the same direction really fast would this cause the earth to spin in the opossite direction thus sending us back in time?

.....it worked for superman
 
If so, I'll hafta just watch. I'm old and can't run. Guess I'll just see you guys when you get back to my time. Or are you already back, and don't know you left? If you do go, when you get back, ALL the ice cream sandwiches in the world will be gone! BTW- visited the Jump Day site- absolutely NO expounding of scientific theory, but---they WILL sell you a T-shirt!!!!
 
Okay, but someone's gotta carry my cooler, I ain't goin without the aforementioned ice cream sandwiches. Course, what with global warming and all, they'll probly melt. OH, WAIT!.. In the future, Jump Day will have fixed that pesky warming thing, so they'll be alright. Main problem as I see it: if you guys stop in Vegas to pick me up, a lot of the faithful might end up at the tables, and we'll only make it to next week or so.
 
if the earth was an apple, the skin would be the parts we know. it is so massive that even a trillion people jumping would make no diffrence.

lets just say that a person will not crush sand as in the original question...
 
What they need to do is get all the ****roaches to jump at once. There is more insect body mass on this planet than there is human, anyway. Get 'em all in one hemisphere, let 'em jump, then RAID 'em on their way down.
 
Even if earth could be moved, it would simply fall back into orbit. Nothing would change. But if we could change the mass of earth and it magnetic properties, perhaps blast 10% of earth into space, earth's mass may change enough to naturally fall in to a new orbit steadily.

You know what would really suck? What if everybody jumped, but instead of pushing earthy farther out, it just increased the speed of rotation? Days and nights would suddenly become shorter, and we'd have 600 days in a year, even though a year is the same length. Weird.

There is no such thing as time. Time was mearly invented to measure between events. If there were no events, would there be time?
 
censorship

PC is everywhere!! (politically correct, that is) Things are pretty tight when a guy gets bleeped for saying ****roaches. Next, it'll be on son-of-a-**n. Vigilante- as per my prev post, it'd be fun, though, wouldn't it, if we had those 600 sunsets in the south?
 
if we all burned massive fires day and night for the next 5 months we could increase global warming and maybe it wouldn't be so f**king cold and wet in ireland....
 
Is this "outwit the techspot board censor" day or something?

seriously though, any force landing on the planet that's enough to knock it into orbit would be enough to case an earthquake instead IMHO.
 
no but it would be hotter than the normal 105F in the summer here in El Paso..... :hotbounce
 
global warming would submerge ireland, as it would other regions of the world. interestingly enough, chicago's official elevation is 666 feet above sea level (hmmmmm.....) glaciers and whatnot would melt a bit and the released waters would raise the sea level and upset the currents (via salt concentrations)
 
not stubborn

The Irish are not stubborn, they are like we Germans - steadfast! He even offered to pick me up on his way to last week. A stubborn man would have kept on running, at least back to the age of chivalry, to throw down his gauntlet. ( While you're there, Irish, have 'em to get them fires goin!!!

And to Zephead: methinks Chicago's elevation might've lifted a bit after Ozzie's boys' feat! Ya think?

Not posible - not even an atom.

The force exerted in jumping is equal to the force exerted on the earth by landing. As both forces operate in opposite directions, they cancel each other out (don't blame me, blame Newton).

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! :rolleyes:
 
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!
 
But then again, if the force of jumping equals the force of landing, wouldn't that just mean that the earth is being pushed twice? Once for jumping and once for landing? And with a second or two in between, that would turn the impact of 600 million people in to 1.2 billion impacts wouldn't it?

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 :D lol

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

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.....
