I note that the symbols defined in the PhysicalConstants package, like
HubbleConstant, do not have the attribute Protected. Is it "safe" to
give redefinitions for these symbols in my code? That is, is there any
reason why I shouldn't write the following?
Needs["PhysicalConstants`"]
HubbleConstant = Convert[70*((Kilo*(Meter/Second))/(Mega*Parsec)),
1/Second];
