Hoarseman

As Newton stated , there is no gravity within a hollow sphere .

But does that mean there is no "net force" on the object -- it is in a state of a dynamic equilibrium of forces --- and therefore ,still suffering internal stresses which threaten to rip it apart 

Or that there is no force whatsoever on the object .? 

Both phenomenon involve the bending of light -- and its "acceleration"

This ritual has gradually taken on its own darker meaning ---  that it is not enough to believe in equality , but that one "has to" demonstrate it in the  proscribed manner -- or face consequences .

It has become reminiscent of the Nazi salute in Germany , where it  became the demanded means of showing support and solidarity with the Nazi party.

The world's climate change ,loss of habitat and damage to the environment is caused by man's out of control population -- are environmentalists being hypocritical if they have more than one child ?
