The three spatial dimensions (x, y and z) of spacetime can be physically demonstrated. However, what about the time dimension? Mathematically, time is a fundamental part of spacetime.
ds2 = c2dt2 – dx2– dy2 – dz2
However, physically where does the time dimension reside? The physical constants (c, G and ħ) all incorporate time. This is not just time in the abstract. Gravity and relative motion affect the local rate of time. On an absolute scale, these constants (c, G and ħ) require coordination with the local rate of time. How do you visualize the time component of spacetime?
This is a discussion question, so I will give my answer to start the discussion. John Archibald Wheeler proposed the uncertainty principle and vacuum zero-point-energy requires that on the scale of Planck length, spacetime must be oscillating at Planck frequency. He designated this “quantum foam”. This oscillation (internal clock) would give every volume of spacetime its intrinsic time dimension. This oscillating spacetime model of the universe ultimately generates a fundamental particle’s gravity and electrical charge.

Is the idea of spacetime oscillating at the Planck frequency an attempt to unite the theories of classical and quantum physics?

The term "classical physics" can imply either physics without relativity and wave properties or merely conceptually understandable physics. The model of the universe I am proposing is based entirely on quantized waves (no point excitations of fields). This wave-based model of the universe is classical in the sense that it is conceptually understandable. For example, it achieves the properties of special relativity (length contraction, time dilation, Lorentz transformations) from the wave-based sonic universe model. The electromagnetic and gravitational forces are also obtained from this wave-based model.
Perhaps most important, this model is supported by the correct predictions it makes. In the proposed model, oscillating spacetime is a sonic medium that generates everything in the universe. If this is correct, then everything, including the forces, are predicted to be united. For example, this model predicts that the gravitational and electrostatic forces between particles become equal at the Planck limit. The gravitational force between two Planck mass particles is predicted to equal the electrostatic force magnitude between two particles with Planck charge. Amazingly, this prediction is correct. Both force magnitudes equal ħc/r2 at arbitrary separation distance r. This and other predictions emerge from the wave-based model of the universe.

Dear Professor Macken,
It doesn't now look like there is a "spacetime"-- rather that space and time have an Absolute character. (The Lorentz and Minkowski schemes, --- these offsets and corrections, appear to apply to light rays-- only.)
