I don't know if it's "too late" to reply here, but ...

Time is just designation of change, and rate of change.  How we mark it doesn't matter as long as it meaningfully resonates.  Language is change/time.  How can you "do" science if you leave time out of the equation?

At light speed, there is NO time, because there is no change (as distance traveled or energy lost).  Einstein also said space in the direction of travel is zero at "c".  Light is a release of energy into the EMF and eventually a reabsorption of that energy from the EMF.  The electromagnetic field cannot be thought of as being "in" spacetime.  It's not a spacetime field.  "c" is a measurement of the "lag" (for want of a better word) of space/time conditions "off of" a singularity state.  Maybe a kind of John-Bell-Zone?

Space and time are mass-related.  That's why relativity of reference frames exists.  The "now" of time is always at the center of each mass, and moves ever farther toward "then" with distance from each mass.  Likewise space, or length, starts with zero at each mass, and length measured extends outward from each mass.

Maybe, you introduce a lot of concepts here. Some of them related to an idea that is your own firstly, Einsteins possibly a second. Do you have a reference to where he said that "space in the direction of travel is zero at "c"." ? A Lorentz contraction is indeed 'infinite' at 'c', validating the concept, but you can turn it about. Doing so all photons are local expressions

...
At light speed there IS time and it is exactly as at 1 m/s speed.
Actually, you ARE moving (almost) at light speed, in this very moment, with respect to some cosmic particle going past the Earth, or with respect to some very far galaxy.
And you cannot avoid the *with respect* part of the story...
