I' m posting these relevant posts about time here with my essay so they do not become lost in the mass of discussion pages. I think they are further indications of the utility of the explanatory framework and of the problem with accepting mathematical theory at 'face value'. This understanding of time overcomes Grandfather, barn pole, Andromeda, and Man riding light beam paradoxes.
The first reply comes after a discussion of a man riding a light beam.

Akinbo, All
Akinbo you make a good point regarding the existence of a photon when "time stops". I will address that issue.
The problem here is lack of differentiation of different kinds of time.
There needs to be at least 4 kinds acknowledged and differentiated in physics, though there are more kinds of time if we include different representations of time such as time that only exists mathematically, internal biologically time, as kept by circadian rhythms adjusted by light exposure times: important for biological organisms, and "Father time" that only exists symbolically and mentally.
The kinds of time important for physics are:
1. time in foundational Object reality, that is passage of time synonymous with the sequential change in configuration of the Object universe. OR.configuration time. Any highly regular sequential change with unchanging accuracy of repetition can be use to represent this such as clock time but only very close to the position of a stationary observer, to avoid significant data transmission and processing delay and affects of motion upon the timekeeping of the clock. This can be likened to "Proper time".
2. time information carried by potential sensory EM data primarily (but also other forms of sensory data ) in Object reality, OR. data time.
3. The time as experienced by an organism or displayed by a processing device. Which is Image reality time. It may be helpful to split that time into outputs that retain the data receipt order and those that do not necessarily.
That's a Basic IR. time and a subjective IR. time.
Now as regards the "stopped" photon. That it is stopped is the relative perception of the observer travelling with it. Yes from that perspective the photon ceases to have a frequency or wavelength because the observer is travelling with the wave keeping pace with it. But the photons in the beam are not themselves changed. There is no Basic IR. or subjective IR.Passage of time that can be formed from the photons in that reference frame.So in that respect there is no time. However the photon beam is still carrying OR. data time that could give Basic or subjective IR. time output to observer's crossed by it's path not travelling with it. Also there is still the foundational OR. configuration time: Object universal passage of time in which these scenarios are happening, that is independent of relative perceptions and data transmission.
That time is both stopped and not stopped is only paradoxical if no differentiation between kinds of time is made.

I just need to add to my previous post that: OR.configuration time is not affected by gravitation or motion , unlike Einstein's proper time. OR.data time and subsequent Basic IR. time is affected due to the curving of the EM data paths within a gravitational field and the Doppler effect. If substantial atomic clocks themselves are running slow when in motion as shown by a permanent change in time shown compared to a relatively stationary clock it is necessary to separately categorize clock time, for moving clocks.
