time space curve ??

The earth and celestial bodies are spheres, much as a bowling ball is a sphere.... without the need for space-time warping..;... which is actually a misconception by Einstein. If you want to understand physics, you have to learn about Aetheric Torsional Hyperdimensional Physics...(googletime).. which explains gravity and "apparent" spacetime curvature in much simpler terms.... as being a consequence of vortexual mechanics................hydrodynamic flow in the aetheric continuum.

I'm confused...

so where is australia...?

and with flatness would that mean that the earth/sun thing relationship is no longer like a pig on a spit being barbecued but maybe more like a succession of suns on a wheel that get switched on and off maybe...

this is actually an excellent geometry problem, requiring a little bit of basic calculus to understand.

??? WHY does the acceleration due to gravity appear to be a constant ~10 meters per second per second near the surface of the earth, while many kilometers above the surface, there is effectively zero gravity ???


Consider that if the Earth was flat, perhaps a disk may thousands of kilometers in diameter.

Near the Center, the force of gravity is caused by the attraction exchanged between massive particles. The force is perpendicular to the plane and its full force on those particles in the Neighborhood is organized without competition.

but considering particles at the Edge of the Neighborhood of the Center, much of the force is actually at a right angle to the displacement from the Center, and that cancelled by the particles on the opposite Edge of the Neighborhood.

that is to say again, the original force is along the hypotenuse instead of the vertical difference, leaving only the sin of the angle in the direction of consideration, while the cosine components cancel eachother out from the other side. so that, the further away from the Center, the less force in the direction of consideration toward the Center.

Only in the case of an Infinite plane in space,

would acceleration be fixed (and not a function of the cube), for any given density and thickness of the plane. in reality we see this in approximation on Earth near the surface, as the constant acceleration 32 ft/sec^2 and away from the surface the field strength falls off.

in fact, it is the finite size of Earth, and the distance to the horizon (20 miles at sea),
that causes gravity not to cause constant acceleration toward the Center from any distance,
but actually to allow objects with sufficient velocity to escape.
