Imagine quickly that we always study space-time, and always both side by side or with similar definitions.

I'd like to propose a line of reasoning where space-time is understood as time within space — time as a form of cognitive understanding within our limited space.

For example, everyone understands the dimensions of space:

• The First Dimension as a point or line...
• The Second Dimension as a plane with two axes, x and y, allowing movement in more directions...
• And our lived Third Dimension, where the third axis z emerges, shaping our interpretation of space and grounding us in the reality we perceive.

However, for us "in" the Third Dimension, we experience TIME "as" a First Dimension, linear and with a single direction — forward, toward the future.
So... 3D Space (1D Time).
Three-dimensional space contains time in one dimension with a single direction.

This leads us to remove time from the Fourth Dimension and consider:
Maybe space in the Fourth Dimension contains time in the Second Dimension.
In the Fourth Dimension, time should exist in 2D.
But with the same limitation we see in 1D time now — a single direction.

If time in 2D had two axes, X and Y, time would flow along a dual axis — forward and upward — in an exponential diagonal.
What would it mean to have time on a dual axis, forward and upward?
If in our current 3D space we have time in 1D, and the speed of light is already extraordinarily fast...

Then in the Fourth Dimension, where time is 2D, light would be slow, almost as slow as gravity.

That being the case… a massive Black Hole that traps light — if it were a portal or rift into a Fourth Dimension — light would be trapped not by mass, but by speed.

I'll explain and develop this further later.
I would like everyone's help.

Thank you.
