Puzzles of Large Scale Structure and Gravitation
Abstract
Description
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.
