I spend a lot of time on this blog explaining a
physical spacetime model and the underlying metaphysics. In this series of
posts, each entry poses a physics question for the spacetime model, along with
the answer.
Physics Question #5. Why is gravity so weak? Gravity between spacetime points is actually quite strong, but
points where elementary fermions are located are gravitationally decoupled from
the overall spacetime by the ratio of the particle's mass to the Planck mass—22
orders of magnitude in the case of the electron. This makes gravity a very weak
force for matter.
Our spacetime model adopts a harmonic
oscillator model for a stationary electron. In this model, the underlying
point's creation time is modulated sinusoidally at frequency ω where, from
quantum mechanics, ω = mc2/Ñ. Thus, the wave function includes a phase difference between the
local time at a particle point and the global time of the universe, which is
the local time at every point that does not contain a particle. It is because
the particle is out of phase with spacetime as a whole for most of the time
that gravity is so weak for particles.
