numbers highlight, or perhaps represent, the nature of   x  

the counting numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, etc. go on forever

there can be an endless numercal value between each of the counting numbers... 1.123456789101112114 ad infinitum

then there can be an infinite variation of the numerical value of the structure of the decimal between each of the counting numbers... 1.112233445566778899 etc.

also..

so  x   means there is an endless number of things that can exist and for each thing that can exist there can be an infinite variation for it

within our flat space reality there are endless variations for weight, size, shape, pleasure, emotion, motion.. and they can be combined and permuted

each and every thing that can exist in our reality can extend to the extremes of the infinite...

weight can become infinitely light

the size of something can be infinitely large or infinitely small

there are an endless number of shapes that can exist

something can move infinitely slowly...
