Now before you excommunicate me, what I want to know is with all these sightings of galaxies 'within cooee' of the big bang, are they all in the same direction?
How far can we see in the opposite direction?
If we can see equidistant in both directions, would that not indicate that we are...
Thats easy. As the roughness increases, the number of points of contact / area will reduce.
Stiction per point of contact, x reduced number of contacts / area = ∆µ < 0
