Putting it in easy perspective, you can observe the ''empty'' space in a box or you would not know it was ''empty''.

Observing the wall of the box tells you nothing about the intervening space. Space could be curled up seven ways from Sunday; you'd never know the difference because light follows the curvature of space. The only way to determine if the box is empty is to measure its mass.
Light is just one way to ascertain the location of the wall. Your arm will do just as well. Both of them must follow the curvature of space. Have you read Flatland?
I have not heard of or read Flatland, is it any good?
Time is solely relevant to the observers position in a gravitational field and relativity to the objects being observed. I've posted a hypothesis potentially explaining the three dimensional reality of space-time fabric that we live in which is enacted upon by four dimensional forces and energy.
The dead fish clock is a good analogy for the arrow of time, but the decay process involves atomic oscillations. The level of stinkiness is just a way of counting oscillations.
Yes your angles can be dangerous.

I agree there is no absolute reference frame.
/the speed of time is one second per second
/Einstein suggested all views are equally valid. Interestingly enough this allows that no view is valid.
/The measured speed of light is unambiguous. The distance measured is ambiguous.

/ Light couples the brain to matter, sight is live, remove away the matter and the coupling is broke, hence we see darkness although it is light.
/Twin two can not be 2016 why twin one is in 2017 because time ran slower for him.
/Time propagates to the future, never to repeat itself. Yet clocks, which we use to measure time, are cyclic, which is not how time propagates. The theory of reincarnation is how clock express time, allowing one to return to a rebirth at midnight, each day.
