Gravity is the result of space-time, and light is apparently affected by that gravity, so no, they aren't part of spacetime's material composition.

gravity is the result of spacetime pressing down onto mass/volume objects ...
My understanding is the other way around, the mass of the object presses down on the fabric of space / time, I also beleve that it must be made out of something, maybe there is where all the dark matter / Dark energy is stored, whithin the fabric of space time itself...
I wonder if we could peek into the infinitesimal way past the particle size we might find that Space is porous, and if you have small enough particles they can fall off the space fabric. To where? I don't know, maybe to a different universe parallel to our own, to the void where the universe bubble is expanding to...
Or if you could take a picture of Plank time you could see between universes like between 2 pictures in a roll of film. would we detect another universe?
I wonder when and if that will be possible...

There is the idea that the actual space-time is more than the three-dimensional universe that we can perceive. Those other seven dimensions are scrunched up inside each sub-atomic particle.
It's like looking at a sandy beach - we just see a two-dimensional space. But look closely and you see that each grain of sand is actually spherical and that there is a certain depth to the beach. That adds another three dimensions. Look even further closely and you see that some grains are actually porous and more like Swiss cheese. That adds even more dimensions.
The heavier an atomic particle is, the more it gets attracted towards these higher dimensions and the harder it becomes to make it move; mass and inertia are all related.

How could they not be? Both fill the known Universe. maybe its right in front of you and you simply refuse to see it.
About spirits? Your statement is as subject as it gets. You don't see it so it doesn't exist. We can't "see" gravity, either.
Or radio waves, sound, wind, X-rays, etc.
You will of course say but we can measure them. Sure, "lately". What about before microscopes, telescopes and spectrum analysis?

My answer to your question:
It is energy, in a state that we have not yet discovered.
Everything is made of energy, in some form or another, we just like to give it different names based on how we observe its behavior.
Space-time is no different, we just haven't figured it out yet.
It is in all likelihood, some substrate of some kind, that has not been quantified or measured yet.

Matter is the kind of atomic phenomenon we've observed with protons, neutrons and electrons, so space-time has no material structure. You are putting the chicken before the egg.
Most people accept a static model of the universe where there was a singular big bang or creation event and everything that exists came from that singular moment. Personally, I think things are popping in and out of existence all of the time and matter is just the most stable conformation of energy so that it is very unlikely to vanish.
Why does matter accrue mass when it speeds up? Is it collecting something at a faster rate than that substance is vanishing?
What if the cosmos is really made up of a cloud of energy/particles that are constantly popping in and out of existence and gravity is the effect of this cloud being attracted to energetic centers like the ones you find in matter. What if in any given moment, several possible futures are suspended ahead of you in the realm of the potential and theoretical and your fate is not sealed until a choice collapses the probability field and crystallizes the future into reality?
What if there are an infinite number of universes coexisting simultaneously and consciousness just happens to be along for a ride in this one, in this being at this moment. There is no reason we should remain bound to this linear causality. We are awareness and that is the purest force in existence. We are universal and timeless and we can go anywhere. ;p

If you had asked, simply, 'what is the structure of spacetime?', you would have been asking a question to which there are any number of well-informed theoretical answers, although, of course, there is no consensus on which of them (if any) is the answer.
But you asked, 'what is the material structure of spacetime?' That's easy to answer. It has none.
Structure of spacetime
Not about whether modern science is full of sh*t when it comes to what it insists can and cannot be existent.
Who taught you that there are "higher dimensions" that attract heavier particles? What proof exists that this is true?

"Modern science" is full of "s***". This is proven every time they move the goal posts.
Whatever the Universe is full of is its structure. Or the "echoes" of it.

You mean "like" the Aether?
Nothing can escape the infinity of a black hole.
Nothing moves faster than light!
[According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light. That speed, explained Einstein, is a fundamental constant of nature: It appears the same to all observers anywhere in space.]
Nothing appears as it seems.
