Time is not a dimension. How can the intelligent physics students confront physics professors delusions of time as a dimension?

Time clearly is a dimension.

Do you know what dimensions are? They are abstract measurement, calibration and indexing frameworks. They are how we measure, calibrate and index an underlying subject.

Example1:- Temperature is the dimension of heat. Temperature is how we measure, calibrate and index heat. Temperature is abstract; heat is real.

Example 2. Space (a word with multiple meanings) in this context is how we measure, calibrate and index relative position.Hence xyz axis. Space (in this context) is abstract, position is real.

And Time (in this context…time is also a word with multiple meanings) is the dimension of change. Time is how we measure change rate.

For example. A change of position is measured in, say, miles.

The rate of change of position, aka motion, is measured in miles PER HOUR. The ‘per hour’ bit is the dimension known as Time.

Time is hence the dimension of change. Time calibrates change. Time (in this context) is abstract. Change is real.

(Btw..if Space is the dimension of relative position, Time the dimension of change, hence Spacetime is the dimension of changing position aka Motion.)

Why is time self-referencing?

Because the word Time has two distinct, core meanings:-

  1. Its the dimension of change. Its how we measure, calibrate and index change and change-events.
  2. Its a collective term for the ‘flow’ of change. A non-specific set of change-events (like traffic is a non-specific set of vehicles).

And Time 1 could be said to measure Time 2.

Hence Time seems self-referencing. But isn’t really. Time 1 and Time 2 are different (abstract) nouns.

If time is an illusion, does that mean it’s not real?

Time is how we reference change; it is both the dimension of change (e.g. ‘per hour’) and the collective ‘flow’ of change (a non-specific collective like Traffic is to vehicles).

One word, two distinct contexts, both referencing change and change-events.

Dimensions and collective nouns are both abstract nouns. Abstract nouns only exist in our collective minds (some say ‘illusion’, I wouldn’t call Traffic an illusion).

The tangible underlying reality is change and change-events. Zillions of quantum and compund change-events. From the universe expanding, earth spinning, your heart beating , atoms vibrating to quarks decaying – change (of which motion, spatial change, is one subset).

So Time is abstract, change is real.

And change is reference-frame specific (not universal as people misunderstand Time to be).
