What is the relationship between time and space? I recently read a book which was based on spirituality wherein an author says time and space are not different as they are interdependent (when it’s spring in Europe, it’s winter in Australia.)

The relationship is that both are dimensions.

Dimensions is a very misused word. A dimension is a mathematical model that calibrates, measures and indexes an aspect of reality using standard units. Dimensions are abstract overlays that quantity underlying reality for us.

So, in the context of Space and Time, Space is the dimension of position and relative position. The xyx-axis allows us to define a position (in space), and relative positions distance. But its a static dimension until we introduce Time, the dimension of change.

So space, measured in say miles, gives us the quantification of the change of relative position. And Time, in say units of hours, gives us the rate of change (hence time is the dimension of change).

Ergo MPH – Miles (space) Per Hour (time)

So merge the dimension of [relative] position (Space) with the dimension of change (Time) and you get Spacetime, the dimension of changing position…aka motion.

So Time and Space are not interdependent. But Space is static without Time.

If time doesn’t flow (block universe theory of time), why do I continue to have new experiences? Why don’t I simply stagnate in time?

The block universe theory proves nothing more than how witless some hypothetical maths based speculation can be.

The ONLY evidence of ‘time passing’ is change. Change is a fundamental feature of the universe. Look around you. The universe expanding, the earth spinning, tides turning, you breathing, atoms vibrating, quarkes decaying…change, continual quantum, compound and universal change.

Time (in this context) is merely a collective term for the ‘flow’ of change. Simples.

And clearly the past changes to become the present which changes again to be the future. Its not hard.

Not as hard as figuring out how supposedly eminent academics could come up with the awful block universe theory.

So change ‘flows’. And change brings you new experiences, and stops you stagnating.

What are you ideas on why time can NOT be considered a dimension?

Firstly, make sure you have a definitive definition of the word dimension.

Then look at empirical evidence.

So, a dimension is an abstract model we use to calibrate and index an aspect of reality.

For exame, Temperature is the dimension of heat. Temperature is abstract, heat is real.

The only empirical evidence of ‘time passing’ is change. We use standard units (years, days hours etc) to calibrate change.

Time is the dimension of change. Time is to change what temperature is to heat.

So, I can’t see anyway that time cannot be considered a dimension. It is (in this context) a calibration and measurement framework, built on standard units. Just look at your clock. Time is a dimension.

Is time thought of as a literal physical dimension (90 degrees perpendicular to our own) or is it something else entirely?

Something else entirely. The ‘fourth dimension’ right-angle thing is a hopeless attempt to interpret spacetime.

Dimensions are (abstract) measurement frameworks. Space (in the context of dimension) measures relative position, for convenience, in 3 right-angles vectors (height, depth, width or xyz-axis).

Time is the dimension of change, i.e. it’s how we measure change rate. For example we measure change in position (aka Motion) in miles PER HOUR. The per hour bit is time calibrating change.

The problem arises because too many physicists don’t seem to understand what ‘dimensions’ are, and don’t understand what Space and Time are within the context of dimension. Hence they really don’t understand what Spacetime is…the dimension changing position i.e. motion.
