What is space really?

Space, not exactly empty. It contains particles(low density), plasma of hydrogen and helium, electromagnetic radiation, magnetic fields, neutrinos, dust, cosmic rays. Maybe more. There is this law of mass, conservation of mass, burning, dusting etc, nothing is lost, created or destroyed.

Space is abstract from my perspective. It seems pretty counterintuitive on the face of it.

The real question for me to think about is "How big is space?" and "How long has it been there?"

Perhaps space has been there since eternity past. I don't think humans will know how long space has been there within my lifetime.

I am obsessed with this topic and really want to know the answer.

we've been taught in school that everything is made of atoms, or mass and energy, but space itself just seems to defy all this.

I really want to know what is space, and what it is made of, and how to define it.
So space aka space-time. Or maybe space-time as one observable layer that is part of the fabric of space. space-time can theoretically be warped there for space can be warped or stretched. It is represented by a 3D sphere, but 4 dimensionally would include the time element and how warping space can warp time. Which makes me wonder about another point if we can theoretically warp space for space travel to get from point A to point B, I am curious how time would come into play. Anyways, yea 3-dimensionally space seems to be like a spherical however multi-dimensional fabric of essentially nothingness, but a breeding ground for subatomic reactions which I theorize stems from sub-subatomic space which may explain how some things seem to appear from nowhere, so maybe sub-subatomic or even the quantum realm is a dimension in itself. The existence of fractal patterns and the infinity symbol may imply infinite dimensions and/or infinitely smaller “quantum” realms. That’s all I got. A vast warpable multi-dimensional breeding ground for matter to emerge.

the key i want to figure now, is space touchable or untouchable

is nothingness untouchable or touchable.

can you feel its existence through touch?

it is obvious that matter is touchable, but space is different. I am unsure whether i am touching its form ot not.

touchable means interaction with physical matter

untouchable means no interaction with physical matter


if space and nothing is touchable, then it is more similar to stuff

if space and nothing is untouchable, ,it might be really null
