One might say that the entire manifest Universe is the sum of infinite little bits.
Indeed, the search for 'what-is-it?' continuously finds smaller and smaller 'little bits'; it is a quantum mystery.
Odd that in the search for some 'unified field theory', one 'little bit' (un-measurable and formless) is essentially ignored.
The consciousness of the searcher, the consciousness of the knower of little bits, the wielder of the math that reveals that the outcome is not accurately measured when consciousness is ignored.
Non-negatable 'consciousness' is the integral unified-field by which the measure of all little bits is known.
