Tightening the Theory-Experiment Connection in Physics: R_{n} based Space and Time

Some aspects of replacing C based physics by C_{n} based physics are discussed. Here C_{n} ={R_{n},I_{n}} where R_{n} and I_{n} are the real and imaginary components of the numbers in C_{n}, and both R_{n} and I_{n}) are sets of length 2n string numbers in some basis. The discussion here is limited to describing the experimental basis and choice for the numbers in R_{n}, and a few basic but interesting properties of R_{n} based space and time.
