How do I live in the 4th dimension?

The so called 4th dimension is Time. Time is the dimension of change.

(Dimensions are measurement sets.)

For example motion (changing position) is measured in, say, miles per hour. The per hour bit is time calibrating the rate of change, i.e. the rate of motion.

And you change (breathing, blood pumping etc), and everything around you changes (the earth spins). To live is to change.

So if you are alive you are changing…i.e. you are living in the 4th dimension.

Is the fourth dimension tangible?

No dimension is tangible.

It is one of the most frustrating aspects of science, the fact that otherwise eminent academics have allowed the word dimension to be so badly misused. (And, yes, Einstein must take some of the blame – but mostly I blame those who came after him)

Dimension means measurement.

A dimension is a measurement framework that we overlay an aspect of reality to calibrate and reference that aspect of reality.

Example – Temperature is the dimension of heat. Temperature is how we calibrate and index heat. Temperature is abstract, heat is real.

Space and Time are both words with multiple meanings. Both have a context as dimensions.

In the context of dimensions, Space is the dimension of (relative) static position, hence xyz-axis. The dimension of Space is how we measure relative static position, using standard units. It is static relative position because, by definition, it excludes Time.

The dimension of Time is how we measure, calibrate, index change. For instance, changing position (motion) is calibrated in, say, miles per hour. The per hour bit is time calibrating the rate of change.

So merge Time, the dimension of change, and Space, the dimension of relative position, and we get Spacetime, the dimension of relative changing position (motion) (in fact relative constant motion, as dimensions are reference-frame specific).

So, in answer to you question, the fourth dimension, like all dimensions, is NOT tangible.

What would the 4th dimension look like to us?

Dimensions are abstracts…they are just how we measure, calibrate and index things. They don’t look like anything, they only exists in our minds.

Space is three sub-dimensions of height, width, depth, or the xyz-axis – which measure/calibrate relative spatial position

You don’t see the dimension…height for instance is just the measurement.

And Time (the so-called 4th dimension) is the dimension of change…it’s how we calibrate and measure Change. Eg Motion (changing position) is measured as, say, miles PER HOUR. The per hour but is the calibration of the rate of change.

So we don’t see the fourth dimension, we don’t see any dimensions. They are abstract models. What we see are the the underlying realities being measured, indexed – that is position, and changing position, i.e. motion.

Why is time regarded as an extra dimension if it is just an effect (or property/attribute) of 3-dimensional space?

Time isn’t an effect, property or attribute of ‘3-dimensional space’. They are 2 distinct, separate dimensions.

Time is the dimension of change (hence ‘rate’…eg miles per hour…the per hour bit is time calibrating change.)

Space (in this context) is the dimension of (relative) position (hence xyz-axis). In fact, Space is the dimension of static position (because, by definition, it excludes Time).

Merge the dimension of static relative position (Space) with the dimension of change, and hey presto you get Spacetime, the dimension of changing position…aka Motion.

That makes Time a pretty important dimension in its own right. Change is what drives the universe, after all.
