I won’t say I am calm but I see an error. The characteristic Schwarzschild radius of E4 meters is E-12 light-years. Thus the result is a factor of 10 smaller. The expansion indicated here equals the original geometric ‘R’ of the universe. Today I will be reading, with a vengeance, on time dependence of the Robertson-Walker expansion. I recall the EFE’s yielding an eq. in time for R, R’, and R”.
