would it take the Earth 8 minutes to realize that there was no gravity to keep it in orbit, or woud it immediately start heading towards Jupiter.

Looks like a controversy here....but no, gravity does not travel faster than light, it would take eight minutes before the earth's orbit changed.\n\n(If gravity was instantaneous, then it would be possible to use that to send messages faster than light!)

The answer has to be A.\nThe time will be the same because Gravitational force does not depend on the mass of the object, since they start with same velocities and accelerate with the same rate they must hit the ground at the same time.\n\nAnd it obviously has to be the same distance because if it wasn't then they would never hit the ground at the same time in the first place. That would happen because if 2 bodies start with the same speed and have the same acceleration but different displacements then their time has to be different.

You would fall slower and slower and never even reach the center. Even if a 10 foot wide cylinder of Earth just simply ceased to exist straight down though the whole thing for your jumping pleasure. Oh,and it's hotter than the surface of the sun down there. And the billion tons of pressure per square inch part. Which is why your hole would close up almost immediately, and form a small self-sealing volcano.\nIgnoring all that you would have to fly up for 4,000 miles.\nYou could come out anyway you want but it's more useful to not be on your head. So head first. Oh and as for your plenty wide hole which is big enough to swallow a king sized bed? It would be like a hair driled through a hill half a mile long.

gravity is highest at the centre of the earth. so you will be accelerating towards the centre.since there is no resistence (assume so that there is no air), you would not stop at the centre due to inertia of motion and continue to go beyond the centre to teh other side. but due to increasing pull on you, you will turn back and continue to oscillate about the center of the earth.\n\nits good for theory but humanly imposible

Nobody has found any evidence for a form of gravity the repels instead of attracting, but that doesn't keep people from looking for it. It may yet be found. But such a force is not needed to explain orbital motion. In fact, it would disrupt orbits, causing the Earth to fly away from the Sun and never return.

By Keplers 3rd Law T² α R³\n\nOr T1²R1³ = T2²R2³\nFor earth R = 1 and T = 1 and for Jupiter R = 5.2\nSo T2²/5.2³ = 1²/1³\nSo T2 = 5.2^(3/2)\n≈11.86 years

The Earth itself (not life on Earth) could die in about 4-5 billion years time.  As the Sun comes to the end of it's life, it will expand and engulf the orbits of Mercury, Venus and possibly Earth too.  If it doesn't engulf Earth then the Earth will remain in orbit around the huge Sun until the Sun has 'puffed' off it's outer layers and shrunk to a white dwarf.  The Earth could then be released from it's orbit if the Sun's gravity has diminished enough, and set out on it's own way through our solar system and galaxy.  What happens then is anyone's guess....

I would say that the most impossible part is when they enter the giant geode. If they were heading towards the center of the earth than when they entered the geode they would enter at the top and fall probably for hundreds of miles and die on impact. Also Giant Geode though a cool thought yeah right.

If there are no gravitational or or frictional forces, then in theory it would travel forever.

Yes they'd revolve around their common center of mass (CM), which currently is located only 280 mi from the center of the sun, the sun's mass being 332830 x earth's.  With equal masses the CM would be midway between their centers.  The CM actually moves a bit due to perturbations from other planets that act on both bodies. \nYou can quickly approximate the new period. The new composite mass (in earth units) is 2 instead of the current 332831, and the radius (in earth-to-CM current  distance units) is .5 instead of (almost exactly) 1.  Kepler's 3rd law says T = (2*pi*R^1.5)/sqrt(G*M), so the new duration of a year is .5^1.5*sqrt(332831/2), or 144 current years, for an orbital speed of 15.3 feet/sec.

Nothin would happen.\nIf you consider two bodies the earth (name it E) and a large mass (m). \ninitially M rests on E. and you lift mass M. the force used to lift it will also act on E.\nAlso if you consider the mass M and E. as a system force exerted on dropping M would be internal and since internal forces do not cause acc. the Earth will not get unbalanced.\n\nThats good for us isn't it...

In earth's atmosphere there is gravity that comes from the core of the earth. In Space, there is no gravity or "Zero Gravity", which means space is does not move except for the obitization of the planets around the sun. But, space is endless, so, we could be falling but never hit because of infinate space. but i do not think we fall.

The actual time of travel from Saturn to the Earth will vary depending on the geometries of the two planets in their orbits, but will be between about 75 minutes and about 92 minutes.

I'd say 17000-19000 miles per hour.\n\nIts at a inclined geo-stationary orbit probably.

Gravity won't let you. You have to go into orbit first, and 1 mph will not do that. You have reach escape velocity to escape earth's gravity, which is 11.2 km/s.

Your question is theoretical and therefore all answers you receive will be theoretical.  I would think that even if it were for a split second, you would feel some kind of pain.  Of course, if you're floating around in space unprotected, you'd be dead before you got there.

So, you would set up two equations and set them equal to each other...first you would have to find the amount of time it would take the mass to fall on earth...then set the equation from earth with the found time against the equation from planet Zog with its gravity as the only variable.\n\nI'll figure it out and give you more of an answer.\n\nalright...ready?\n\nI was stupid...just use this equation:\n\nY = Yo + Vo t + .5 a t^2\n\nwhere Y is the final height (zero), Yo is the initial height, Vo is the initial velocity (zero), a is the acceleration of gravity on the planet Zog, and t is the time it takes for the mass to hit the ground.
