Apologetics 301 Guidelines
If you think this is the area where you tell everyone you are sorry for eating their lunch out of the fridge, it probably isn't the place for you
This forum is open discussion between atheists and all theists to defend and debate their views on religion or non-religion. Please respect that this is a Christian-owned forum and refrain from gratuitous blasphemy. VERY wide leeway is given in range of expression and allowable behavior as compared to other areas of the forum, and moderation is not overly involved unless necessary. Please keep this in mind. Atheists who wish to interact with theists in a way that does not seek to undermine theistic faith may participate in the World Religions Department. Non-debate question and answers and mild and less confrontational discussions can take place in General Theistics.

Thank you. Space becomes time and time becomes space. I read something recently from Kant, saying something about space didn't really exist. That space is all a construct. Not that it would matter I suppose. Some people say time is illusion, but you never hear anyone saying space is. I'll see if I can find that passage and post it if anyone is interested.

Here is a pretty good article on the concept:

Space is not something objective and real, nor a substance, nor an accident, nor a relation; instead, it is subjective and ideal, and originates from the mind’s nature in accord with a stable law as a scheme, as it were, for coordinating everything sensed externally. (Ak 2: 403)

I kinda guessed those. But the upper left and lower right are even harder to read.

Space distance 2-D: √(∂x^2)+(∂y^2)
Space distance 3-D: √(∂x^2)+(∂y^2)+(∂z^2)
Space-time distance: √(∂x^2)+(∂y^2)+(∂z^2)+(i∂t)^2
Because space-time distance is an extension of space distance.

Another corollary of special relativity is that, in effect, one person’s interval of space is another person’s interval of both time and space, and one person’s interval of time is also another person’s interval of both space and time.
In 1908, Minkowski offered a useful analogy to help explain how four-dimensional space-time can appear differently to two observers in our normal three-dimensional space. He described two observers viewing a three-dimensional object from different angles, and noting that, for example, the length and width can appear different from the different viewpoints, due to what we call perspective, even though the object is clearly one and the same in three dimensions.

With special relativity, your expressions above can spontaneously swap? Or maybe the axis' will rotate under certain conditions...such as black holes?
When it is said that space becomes time and time becomes space in black holes, does the entire 3 axis (x, y, z) become time? Surely all three would become time. You couldn't have just one axis turn into time.
Also, are there such a thing as quantum black holes, or any sort of equivalent where time and space swap on the quantum scale?
