Correct. Just as all measurements are.Time as measured in units of measurement is of necessity relativistic.
Zero, or 'ground' is nothing more than a reference point that you choose.
Nope. You are using 'now' as your 'zero point'. Anything in the future relative to that point. Anything before is relative to that point.However, the concept of something before and after everything is independent of units of measurement,
Quite right.at least in the way my perception of a mind is working.
Yet, before and after alone are still relativistic by definition.
Heh. Sometimes an old dog CAN learn new tricks!As a geriatric, my intellectual curiosity is rapidly waning,
yet I can be moved to think about this stuff when you post about it!

By definition. Quite right.Thinking that the universe is all that there is is precisely why I think that it's infinite.
If it's not infinite, there would be something outside of it, in which case it would not be a UNIverse.
It isn't. It is simply a speed.What I DON'T understand is why the speed of light is regarded as a limitation on time.
A photon will travel at different speeds depending on the medium it is traveling within. That is why things like rainbows, glories, blue sky, prisms, Snell's window in water, and camera lenses all work. The speed of light in a medium, regardless of that medium is the speed of the photon in that medium.
The Speed of Light, as used as a reference point in several theories of science, refers to the speed of a photon in a vacuum, about 299 792 458 m / s. It really can't be measured accurately, since the communications path for any measuring equipment is also subject to the speed of light.
Rather tough to measure, since all measurement equipment is subject to the same speed of light to communicate between the distance of the source and detection.I think that it theoretically is--
they don't teach that in either accounting or labor relations courses--
but we don't know for sure that something can't happen faster than that, do we?
Therefore, as Heisenberg so eloquently declared, it's not possible to know the speed of a particle and it's location at the same time.
Because of that, there really is no way to observe anything being faster than the speed of light. Of course, that does NOT preclude that something may be faster.
This problem is sometimes referred to as 'probe interference'. The act of measurement itself changes what you measure!
