Gravity in the qm

Galileo and others recognized the similar effects of acceleration and gravity.  The qm view provides physical causes for this observed similarity.  The causes are explained at various locations on the qm view website, and the reader will be directed to one of these explanations after the following necessary information.

Acceleration and gravity both involve energy-exchange imbalances within systems of mass/energy, including bodies of all sizes.  In the qm view, all systems of mass/energy are comprised of energy quanta, which are oscillations of the qm that move through the qm with absolute speed, ca, when not impeded by the effects of mass/energy in the qm.

We will represent a simple mass/energy system by a box within which two photons are emitted at opposite ends (left figure).  Each photon travels to the opposite end of the box where it is absorbed (right figure).
If the photons' sources emit them with the same oscillation frequency (and thus the same energy), and if the box is at rest in the qm, then the energy transferred by each photon to the opposite end of the box will be the same.  The energy transfer between the ends of the box will be balanced.  At each end of the box the energy emitted will be equal to the energy absorbed.  Even if the box is moving through the qm with absolute velocity, va, along the line of photon travel, the energy exchange will be balanced because the Doppler shifts of the photons' energies at emission will be offset by the Doppler shifts at absorption.

However, if the box is accelerating along the line of photon travel, the energy exchange between the box ends will not be balanced because the velocity of a photon relative to the box changes between emission and absorption.  The larger the acceleration, the larger the energy-exchange imbalance, and the larger the internal force in the system due to the imbalance.  For a massive body (e.g. a kilogram mass), a huge amount of energy is being exchanged within the body, and a small energy-exchange imbalance can result in a substantial net internal force in the body, which is equal to the external force on the body necessary for the acceleration.  This is discussed on the Equations page, where the reader will be directed via the link below.  The internal energy-exchange imbalance, and resulting net internal force in a body exactly account for the body's inertia (resistance to acceleration).

Gravity involves similar energy-exchange imbalances within bodies, but the cause is fundamentally different.  The basic cause is the fact that a massive body (e.g. Earth) influences the speeds at which energy quanta move through the qm in its vicinity.  This observed fact is supported by verifiable evidence of photons traveling slower when nearer the sun.  And if the energy exchanges within a mass/energy system (e.g. atom) are slowed, the evolution of the system will be slowed, which decreases the oscillation frequency of the energy quanta emitted by the system.  Therefore, atomic clocks that are closer to Earth or the sun should evolve slower than clocks farther away.  This also is consistent with verifiable evidence of atomic clocks running slower near massive bodies.

The following link leads to a detailed explanation of how the gradient of the photon-slowing effects around a massive system (e.g. Earth) causes internal energy-exchange imbalances within bodies (e.g. people) in the gradient, which cause internal forces within the bodies that result in the observed gravitational attraction of the bodies toward the massive system.  Link to physical causes of gravity.
