Keeping this in consideration, where is the newtonian focus located? A focal position for a reflecting telescope at the side of its tube, at right angles to the incoming light.

How fast can a human go without dying?

This is a well documented field, and the average maximum survivable g-force is about 16g (157m/s) sustained for 1 minute. However this limit depends on the individual, whether the acceleration is applied to one's entire body or just individual parts and the time in which the acceleration is endured over. Then, what is the speed of dark? Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light.

In respect to this, do microwaves travel faster than visible light?

Yes. Microwaves are electromagnetic waves; as is light. The difference is wavelength/frequency. The fastest speed possible. What two waves lie in both ends of microwave? Radio waves and microwaves lie at the longer end of the spectrum of electromagnetic energy (kilometers and meters to centimeters and milimeters), while x rays and gamma rays have very short wavelengths (billionths or trillionths of a meter).
