Conclusion:
'' . . . future thinkers might ponder physics using the
information encoded in quantum entanglements,
which weave the space-time to grow potatoes in the first place.''

Conclusion:
Future thinkers need to ponder about ''an absolute space-time''
where ''potatoes-particles grow '' in the first place.

We live in concrete Euclidean / Descartes world ( 3-D + time )
Minkowski's '' an absolute space-time '' is a different world.
Why physicists use the mathematically beauty of 4-D and give
ONLY an ABSTRACT, not CONCRETE image of this beautiful WORLD ?

We live in concrete Euclidean / Descartes world ( 3-D + time )
True at the scale of our everyday lives.

NOT TRUE at scales where relativity is important.

Because it describes the observed phenomena MUCH better than Euclidean
geometry (3D+time).

Hopeless. Humans live at the scale of our everyday lives, which is never
going to "see" the 4-D spacetime of relativity. But that does NOT mean
relativity is wrong, it just means it is important at other scales.

In your everyday life you cannot walk on the ceiling.
But ants do it all the time. The scale of an ant is
MUCH closer to the scale of your everyday life than
the scales where relativity is important.

There is an ant and there is celling
There is quantum particle and 4-D
Ant can walk on the celling because it has sizes.
Q-particle travel with constant speed in absolute 4-D
The speed is fast then the 4-D sizes are not micro but huge

If SRT is true theory, then
why an absolute 4-D is an abstract concept ?
#
There is quantum particle and there is an absolute 4-D
Q-particle travels with constant speed (c) in an absolute 4-D
Its speed is very fast then the 4-D sizes are not micro but huge
Can 4-D be observed ?
#
The second postulate is stated as:
Light is always propagated in empty space with a definite -
- constant velocity (c ) that is independent of the state
of motion of the emitting body.
Question:
Is ''empty space'' an absolute 4-D ?

or much simpler :
there are here physical entities
that were here EVER SINCE
no one created them !!

philosophically and logically it cant be otherwise!
even ancient people understood it !
