I guess there were other elements to the puzzle that needed to fall in place before Einstein (1879 to 1955) and Minkowski (1864 to 1909) realized that time was the fourth dimension. — TheMadFool
This is an over-simplistic description of why time is considered a dimension. — T Clark
So if dimensionality is defined by spatial existence time would be better represented as non-dimensional, or the 0th dimension. — Metaphysician Undercover
And, afterward, from them, the preferred mode of time became to be the block universe of eternalism, in which past and future both exist, this opposing our naturally perceived notion of presentism, — PoeticUniverse
Yes. Continue please... — TheMadFool
Presentism does not just amount to the assertion that only present events or entities exist, but also that the present undergoes a dynamical ‘updating’, or exhibits a quality as of a fleeting swoosh, and this additional dynamical aspect is what threatens the substance of the debate between the presentist and an eternalist opponent. — PoeticUniverse
In other words, what is going to exist or was existent, as the presentist must refer to as to be or has been is indicated as coming or going and is thus inherent in the totality of What IS, and so it has no true ‘nonexistence’, for this as Nothing cannot be. There is no contrast between a real future and an unreal future, for what is real or exists can't have an opposite to form a contrast class. — PoeticUniverse

Space and time are mathematically linked. — fishfry
I received your SOS; you are lost somewhere in time, around 1912. Alert: Do not board the Titanic! — PoeticUniverse
Space and time are mathematically linked. — fishfry
What would this link be? I'd like to know if you're willing to teach. — TheMadFool
The link is synthetic, we link space and time with mathematics. How space and time are really related we haven't the foggiest idea. That's because we do not know what neither of these is, nor can we even describe what space or time is. — Metaphysician Undercover
Yes, now what about the way that mathematics links space and time, when will that be overturned? — Metaphysician Undercover
I don't think time is a dimension. Dimensions are infinitely divisible. But nothing can be infinitely divisible. Therefore, no dimensions exist. Time does exist. Thus, time is not a dimension. — Bartricks
If I run across a halfway decent explanation online I'll post it.

4D—your world-line;
5th, all your probable futures;
6th, jump to any;
7th, all Big Bang starts to ends;
8th, all universes’ lines;
9th, jump to any;
10th, the IS of all possible realities — PoeticUniverse
What do you make of infinite-dimensional spaces? An example would be the set of all continuous functions from the real numbers to the real numbers. This set is an infinite-dimensional vector space. — fishfry
I think that math infinities don't count as actual infinities, they just being potential infinities, and that actual infinities are impossible since they can't complete, much as the definition of 'Infinite' hints at, plus that 'infinite' is not really an amount or a number, also because it cannot be capped. — PoeticUniverse
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
