  We consider the puzzle of cosmic voids bounded by two dimensional structures
of galactic clusters as also a puzzle pointed out by Weinberg: How can the mass
of a typical elementary particle depend on a cosmic parameter like the Hubble
constant? An answer to the first puzzle is proposed in terms of ``Scaled''
Quantum Mechanical like behaviour which appears at large scales. The second
puzzle can be answered by showing that the Gravitational mass of an elementary
particle has a Machian character.
