Do dimensions physically exist, or conceptually?

Question

Like 'depth' and 'time'. Does 'depth' physically exist or is 'depth' a concept?

Answer 1

I am afraid your question is too deep for a simple answer. Aristotle's answer would have been "no" because we use such things as a concept to categorize things. According to him only real things exist and are singulars, but when we try to classify things we are merely using verbal expression. Plato on the other hand would have said that dimensions exist because there is a form for dimensions and that every dimension is just a form of a single dimension.
As far as time is concerned, I recommend you read St. Augustine who discusses weather time exists or not.

Answer 2

Physical reality is always a good place to begin the experiment.
Place your head against the surface of a block wall, the part you can see assuming you are not blind, and then press your head against the surface as hard as you can until the molecules of the wall begin to merge with the molecules of your head and continue this procedure until your head exits through the perceived other side and measure the distance your head traveled. This should answer your question.
If this procedure fails then just try hitting your head a little harder against this same block wall until the desired molecular fusion starts to happen as described.
This might beg the question "does asiprin really exist?" after the experiment is completed.

Answer 3

Existence is the interaction of Energy and Space-Time.

Measuring is conceptual. But spacial dimensions exist because that is the definition of existence.

Apology for the tautology.

Answer 4

It exists in our world. Back to the mountains--if they are being seen the same way by millions of people over generations.....it must exist. It is a concept based on our human knowledge. Our concepts are biased on consistent preceptions, which depends on a unified continual unified percept of many people over time.
I do believe that outside of our reality, our conceptions that are based on what we perceive are consistent and real, in our world- will be challenged eventually when to die and enter a totally different dimension.

Outside of our world, there is no way to assume that our laws of nature are the same than a planet millions of light years away. I believe our view of what is real, isn't real outside of our place & time frame.

I believe in the spiritual world. I believe that we have no concept of what it is. I have a son who died and I continue to wonder if he understands the mysteries of the universe.
I would be more apt to ask if our spiritual life is based on what we want to see or do. I have no interest in streets of gold or a mansion or a crown. I believe heaven is what we want it to be because we will be spirits. My heaven will be streets of chocolate. *smile*

Answer 5

is physics not a concept?
if you mean that something has to have mass to be physical, then no. Just think carefully about your question.

Answer 6
