if gravity is geometry, how come that geometry produce work?
geometry has no energy, nor gravity has energy, becus if
you want potential energy, you need first to invest that
energy in elevations and such
Please consider this:
Gravitational energy in released from the Earth out into space at a
certain rate over time. When these gravitons come into contact with
gravity dont propagate and is not energy, is geometry which may
produce work
other energy (mass or light), they draw that energy toward the Earth.
This gravitational attraction rate near the surface of the Earth is
observed to be 9.81 m/s of acceleration per second "downward".
there is no attraction
Because of this, an equal but opposite amount of work has to be
performed just to maintain a constant distance from the surface of the
Earth over time. ex: A hovercraft. To accelerate outward would take
even more work. ex: A rocket destined for outer space.
no, tha hover is in freefall while both he and the
earth expand at same rate, therefore is tha earth
pushing up against tha hover and not tha opposite
It might be good to look up all that you can on the escape velocity
equation.

Correction: The equal and opposite acceleration needed to counteract
gravitation is only the minimum required. That said, it can only be
assumed that a hovercraft is not perfectly efficient. Energy is spent
doing things other than maintaining the constant distance from the
Earth. ex: Vibrations in the skirt material, etc etc etc.
The potential only exists when it's not gravitating something. When it
does, the gravitated energy undergoes Special and General relativistic
time dilation, and velocity/momentum increase (potential -> kinetic).
Differential geometry is used to define the path of energy under
gravitation. It's a mathematical tool used to define a 4D continuum on
paper or computer.
If gravitation is not attraction, then what is it?
If gravitation is geometry, then what was holding the Earth and Moon
in place before geometry was invented?
- Shawn
I'm trying to say that before differential geometry was invented,
gravitation was not algebra. Algebra was a tool used to describe the
path taken by a body under the influcence of gravitation, and nothing
more. Same goes for differential geometry. I doubt very much that I'll
convince you of anything, but I thought it might be useful to share an
opposing point of view.
