Oh, I see. Simple enough.

comment Is time fundamentally different from space?
That is a good argument, and one that I was hoping I would get. But how does the generalized form of that equation look like? Or, at least, how does it look if you introduce another dimension?

comment Is time fundamentally different from space?
@VineetMenon Could you please post an answer explaining why time is fundamentally different from other dimensions? My current understanding (as a non-physicist) is that "spatial" and "temporal" dimensions are the same things, but they have different names because we experience them differently. I guess you could say that the distinction is that movement is restricted in the fourth dimension, but do we know that to be a characteristic of the dimension, or is it a limitation of our technology?

I did not know there was a Theoretical Physics board here on SE. If you think this question is better suited there, please move it. theoreticalphysics.stackexchange.com

+1 "Flatland" seems very interesting. Thanks for pointing it out.

"With respect to the brain scan: this way of visualisation is chosen for simplicity" -- I know, but that is besides the point for this question. :) I picked that image because it illustartes how 2D scans in rapid succession look like a substance that evolves over time.

"you can in principle move freely forward and backward, while in time, your motion is fixed" -- But is that a characteristic of the dimension, or a limitation of our technology and/ or dimensional nature? Afaik, there's no evidence that time travel in the past is impossible, so there's nothing that can be said for certain about that for now.
