Nice video and presentation.
Space is an abstract and is empty of anything. When we place something inside, like a yard stick, can space have dimensions. But dimension isn’t space, only gave us the illusion of space.

Time is also abstract and empty of everything. When we place something inside, like a clock, can we have time. But a clock isn’t time, it only gives us the illusion of time.

Time & space are two unrelated entities and are dimensionless. Marrying them together is meaningless. Meaningless is something good to kill time. 😊

You can also create a simple geometric diagram representation of motion of an object within space-time, via the use of motion vectors and length scalars combined, and then take advantage of this single representation to derive the SR mathematical equations in mere minutes, including deriving the Lorentz transformation equations.
