Is Gravity a dimension since we feel its effects, as many of us feel heat from the Sun or understand a rectangular prism?

Feeling the heat of the Sun, and feeling it’s gravity, are obviously two different things.

I’m not sure if I could properly articulate, what I consider “life” to be…

Allow me to unlock the door to your rectangular prism:

Gravity is a force to be reckoned with.

A dimension is a measure of the space in which reality unfolds.
Heat and gravity are our sensory perceptions of energies/forces acting in space-time dimensions.

No. Time should be a dimension, as should mass, perception, and velocity. IMO.

Indirectly, sort of. Gravity is a force that is caused by the warping of spacetime and the creation of an acceleration field. So it’s caused by a warping of dimensions.

Pfft!
Dimension is the specific state of existence in which one dwells. Temperature, gravity, aging, are forces experienced within that dimension. Living three dimensionally in any other place is still third dimension, relocated.
Gravity isn’t even an alternate universe.

Weight should be a dimension, but is not on any list I can find.

What is the thinking behind the several statements, “XYZ should be a dimension” ??
Do these things somehow “seem” like a dimension just because they are measurable?

Gravity is a phenomenon, not a dimension. It varies depending on which planet or other spatial body you’re on, and it has to do with speed/velocity and mass, two things that I think should be dimensions.

Are we talking poetry here? What’s with “should be a dimension” ?

In science / engineering terms there are three spatial dimensions plus time in which our human existence unfolds, According to string theory there are several more collapsed spatial dimensions. That’s it folks, those are the dimensions.

Now if it’s poetry you’re working with then go ahead with things that seem like they should be dimensions to you, and it that case anything can be a ‘dimension’ but it’s true only in that interpretive context.

I guess with any dimension, it’s all how you look at it…
Poetry is a good interpretation, but it’s more like art, IMO…

No, it isn’t all how you look at it, words have meaning…

I said poetry, not just words…
