Time dilatation exists not in the sense that time as a fourth dimension of space dilates and as a result the clock rate is slower, he explained.
Each clock's ticking mechanism consists of a photon being reflected back and forth between two mirrors, so that a photon's path from one mirror to the other represents one tick of the clock.
The clocks are arranged perpendicular to each other on a platform, with clock A oriented horizontally and clock B vertically.
Inertial mass and gravitational mass have the same origin: diminished energy density of a quantum vacuum.
This model gives exact calculations for the Mercury perihelion precession as calculations of the general theory of relativity. Explore further: Scientists suggest spacetime has no time dimension More information: Amrit Sorli and Davide Fiscaletti.
Sorli explained that this idea that both photon clocks tick at the same rate is not at odds with the experiments with flying clocks and other tests that have measured time dilation.
This difference, he says, is due to a difference between photon clocks and atom-based clocks.
GPS confirms that clocks in orbit stations have different rates from the clocks on the surface of the planet, and this difference is valid for observers that are on the orbit station and on the surface of the planet.
So interpreted, 'time dilatation' does not require 'length contraction,' which as we show in our paper leads to a contradiction by the light clocks differently positioned in a moving inertial system. He added that the alternative definition of time also agrees with the notion of time held by the mathematician and philosopher Kurt Gödel.
Instead, time as a numerical order of change exists in a 3D space.
Our model on space and time is founded on measurement and corresponds better to physical reality. To illustrate the difference between the two views of time, Sorli and Fiscaletti consider an experiment involving two light clocks.
With clocks we measure the numerical order of motion in 3D space, Sorli told
