    Thinking about the OP question. Seems to me that Einstein did not consider time as independent from space, but more as a mathematically necessary permission for space and change to unfold, persist and evolve.

    An object "needs" time to remain an object which is what it wants to do, but in order to do so it must shed energy and that process "requires time" (enough for the duration), a necessary and mathematically implied sufficient temporal permission.

    Time = x (any value). It is part of the Function.
    This phenomenon is explained here;
    https://en.wikipedia.org/wiki/Necessity_and_sufficiency

    I believe Einstein looked at it from a "necessary and sufficient" perspective when he came up with the term "spacetime"........

    .......the very definition of a necessary and sufficient self-referential condition in accordance with Occam's Razor.

    spacetime = 3D coordinate of space geometry, an address. Time = chronological quantum movement from one 3D spacetime coordinate to another, @ "c".

    It is the "c" restriction which is causal to the necessity for time. Time is a qu-bit....

    If only you had said AGE and not TIME that would be perfect

    I consider them interchangeable, but I like the immediacy of duration; "I'm late, I'm late for a very important date"!
    We experience duration every day, we experience age every year...in celebration of our birthday.....

    The past only exists in the memory of the subject and the future in his imagination. Real time is the duration or continuity of things in a certain state or situation. There is only the continuous present equal to time, cp = t. Clocks measure time, the continuity of things in the present.

    This is mystical nonesense.

    I repeat my earlier assertion - science is founded on the principle of causality. That is, every event has a cause (past) and every event has an effect (future).

    It is true that in the quantum world things are not quite that simple - one says that an operator acting on the state of a quantum system has a certain expectation value.

    It can be shown (but not easily) that this is a form of causality.

    I repeat, any science that defies the principle of causality is junk

    You should say: Each event has a cause (before) and each event has an effect (after).

    No. I said what I meant, and I meant what I said.

    Think........

    You can correct, nothing happens.

    What does continuous present mean?

    Time flows in the present and is perceived as a continuous succession of irreversible moments that goes from the past to the future.

    The atomic clocks at NIST and all common clocks don't measure 'time', they meter time in a convenient interval. It aids in establishing order like: GPS, air traffic control, roadway traffic, communications, appointments, bills due, etc. I.e. everyday life.

    They meter AGEING and linked with numerous other linked systems incorporated in numerous other equipment the SYNCHRONIZATION of the workings of the combined systems

    Age is the duration of something, and it's calculated as the difference in time of introduction and time of disappearance.

    Noooooooo

    AGE is calculated from one arbitrary moment to another arbitrary moment

    AGE is not TIME

    For the purposes of the twin "paradox", the traveler knows the date and time when the home twin (she) was born. It is exactly the same date and time when the traveler (he) was born ... they are twins. So, at any later time in his life, if the traveler knows the current age of the home twin, he knows the date and time on her wristwatch. So in that case, her age is EXACTLY equivalent to the date and time at her location.

    For the purposes of the twin paradox the traveler knows the arbitrary labelled moment when the home twin was born ✓

    It is EXACTLY the same arbitrary labelled moment when the traveler was born because are twins ✓

    So at any later moment in life if the traveler knows the current AGE of the home twin the current arbitrary labelled moment on twins wristwatch is known ✓

    So in that case home twins AGE is EXACTLY equivalent to the arbitrary labelled moment at current location ✓

    I don't understand the distinction you're trying to make between measuring time and metering time intervals. Please explain.

    I'd guess he means that an interval of time on Earth would not be the same Interval of time on a satellite. Dilation is why clocks will record different times at different accelerations. Unsure what he meant about Aging though? People would respectively age the same from their own perspectives.

    Introduction and interference of time?

    I don't think that's what he's saying. I think he would say that whether you use a clock on Earth or in a satellite, you're still not measuring time; you're only "metering time in a convenient interval". I just don't know what his distinction is between the two forms of words.

    There is no such animal as TIME

    Seems like some people will go to extraordinary lengths to measure something which does not exist

    The link gives details of why accuracy of a clock in deep space is required

    As I understand the situation if you calculate some sort of situation on Earth and set up the clock on the probe (or whatever equipment is being sent out there) the further out the more the clock will drift and the more imprecise the Earth calculation will become
