What makes it static? I’ve said spacetime originates in the extra dimension ..it is known to bend.None of the 3 spatial dimensions can bend. Height cannot bend, Width cannot bend, Depth cannot bend. If you draw a perfect (idealized) triangle or a square, it's impossible to join all the ends, due to curvature of space.
This is from ; curvature - What does it mean that spacetime is curved? - Physics Stack Exchange
Mathematically, curvature means that you can model space(time) as a (pseudo-)Riemannian manifold with nonzero Riemann tensor. There is no important difference between space and spacetime being curved; spacetime is essentially a four-dimensional space, with a few quirks that are not very relevant here. Spatial dimensions are different from the time dimension but not as much as you'd expect, so it turns out that spacetime is the best model to describe reality.In more accessible terms, curvature means that you can draw a triangle and find that the sum of its interior angles is not 180º. It means that you can draw a circle and find that its circumference is not 2π2π times its radius. It means that if you try to draw a square starting from one corner, after drawing the four sides you will not return to the same place as where you started. It means that if you grab an arrow and transport it along a closed loop keeping it parallel to itself, you will not end up with the same arrow that you started with.
It doesn’t really make sense to say that a dimension such as time is curved, but if you want to understand what it means, the simplest aspect is that time passes differently in different places, corresponding to the gravitational field. Since objects move in such a way as to maximize the time they measure between two events, this “position-dependent time” affects their trajectories. This is not the whole story, but in many situations it’s the most important effect.

Hmm, I have to admit you are clever.
You are challenging me on whether the fabric of spacetime is spatial or not. I had assumed it was due to how weird a fourth spatial dimension would be, but now I question it. Spacetime is all the dimensions combined, but the fabric originates in the fourth. I guess there isn’t anything saying that fourth has to be spatial for the fabric to live there. The fabric could be made of something we haven’t thought of before. Maybe made of some weird quantum structure?
Dark Matter could still live there because it could exist as virtual mass.
Is the Dimension of SpaceTime, Temporal and Virtual?
I don’t really know, I can only ask questions.
But I do like your concept of emergent superstructures, i.e. “the whole is greater than the sum of its parts”.
This is something Max Tegmark might say and I like that image of emergent potentials from combining simple values and functions.
Fractals are like that. A very simple equation of self similar additions being responsible for the emergence of the most incredible fantastical patterns
Could the fabric of spacetime be something like unphysical matter waves? It is in the dimension of observation but maybe it doesn’t have the ability to be observed …just like dark matter.
Could the fabric of spacetime be something like unphysical matter waves?If I knew what that was I might be able to answer it. But I don't think you know what you are asking Joseph.
unobserved matter waves are not physical
Does 3D mass activate the fabric of spacetime (which is made of 4D virtual mass)? The bending of spacetime is causing what appears to us as dark matter? Does it take a certain amount of mass to activate? Is that why there is a quantum/classical boundary?
Spacetime originates in the fourth dimension ..that is the only part Einstein didn’t see.Repeating the claim isn't going to make it any more true. No, space and time did not originate within time. Time did not giver birth to itself.
It would be super great if you would just go away.
“there is no expedient to which a man will not resort to avoid the real labor of thinking”
Is there a connection between the quantum field and the spacetime fabric in the time dimension? Are unobserved matter waves, virtual mass in 4D without time? When it is given time it becomes physical in 3D and the 4D is used for time.
IMO, reality itself is an emergent phenomenon. It’s all about wave functions collapsing into apparent physical patterns, such as particles, or audible sound, or the associated measurement of duration.
i.e. nothing exists in our reality until it is “observed” by a collapse of the wave function. Dimensions are relative categories. An insect lives in a totally different dimensional world from humans. A fish lives in a totally different dimensional world from insects. It’s all relative to the “observer” and the “method of observation”.
You are pretending there isn’t a quantum/classical boundary. The moon is still there if no one looks at it. Schrodinger’s cat is not in superposition.
Matter waves do not age …they do not decay. A physical state turns a wave physical before it starts moving.
4D virtual mass is unobservable. A physical state from spacetime is transforming the 4D to 3D + time.
Dark Matter is unobservable, but doesn’t have the ability to gain a physical state.
We do not observe matter, we observe light waves emanated by matter. It is only when light waves collapse on a sensor does an physical pattern appear.
Without light waves, matter becomes invisible. Perhaps this is why Dark Matter is invisible, it does not emit wave lengths in the visible spectrum.
You act like only visible light tests were performed on Dark Matter. We tossed every possible test we have at it.
That is an interesting angle though …we see matter from the bounced light off the object. …unless it glows.
Even then, we can only observe something by the collapse of its wave function, no?
IOW, can something exist without an inherent wave function? What happens when a standing wave collapses?
Wave function collapse
In quantum mechanics, wave function collapse occurs when a wave function—initially in a superposition of several eigenstates—reduces to a single eigenstate due to interaction with the external world. This interaction is called an "observation". It is the essence of a measurement in quantum mechanics which connects the wave function with classical observables like position and momentum.Collapse is one of two processes by which quantum systems evolve in time; the other is the continuous evolution via the Schrödinger equation.[1]
Again, you are pretending the quantum/classical boundary isn’t a thing. I’ve discovered what quantum waves are …they are 4D …until they observed/decohere and become 3D physical + time. It explains why we can never see quantum waves …we can’t see anything 4D.
Is there a connection between the quantum field and the spacetime fabric in the temporal dimension?
Are unobserved matter waves, virtual mass in 4D without time (don’t age/decay)? When it is given time it becomes physical in 3D and the 4D is used for time?
A physical state turns a wave physical before it starts moving. It isn’t a wave anymore at that point but can still be influenced by the quantum field.
4D virtual mass is unobservable. A physical state from spacetime is transforming the 4D to 3D + time.
Dark matter is unobservable, but doesn’t have the ability to be given a physical state. It remains virtual.
Does observation/spacetime swap quantum waves by giving it a physical state and a timeline? The wave function can propagate, but the wave doesn’t age until given a physical state.
“Observation” is saying the same thing as “spacetime got involved”
Decoherence doesn’t require a human knowing about it. Spacetime represents our reality and converts virtual quantum information to physical/real objects.
The temporal dimension is where the fabric of spacetime originates, anything there is 4D by default. It isn’t spatial but mass can live there as quantum waves …virtual.
