This document discusses important questions about fundamental physics concepts like the speed of light, Heisenberg's uncertainty principle, and Einstein's theory of relativity. It proposes that space and time are quantized at the Planck scale to explain these phenomena. Key points:
1) Space is made of discrete 3D "quanta" of space the size of the Planck length, and time is quantized in units of the Planck time.
2) Between these quanta are additional dimensions that allow energy and information to flow faster than light.
3) Quantization explains limits like the speed of light and Heisenberg's uncertainty principle by removing the possibility of exactly locating a particle within a quantum of space or
