I am now going to ask you to do something that will do violence to every instinct of a trained scientist:- Recognize that it is indeed one piece! An object isn't a collection of separate particles moving randomly within a local space. It is one big particle with no empty places inside it. Think of it as exactly what it looks like, all the way through. It is no different than it looks. There are, of course, very fine grained density gradients all through the unit, and you can't see them overtly.

What is a "quantum foam" and what is "space-time", other than a mathematical abstraction invented by Minkowski? if you want to know WHY a moving object's path is curved by minkowski's "curved 4d space-time manifold", (in which - since 1911 - all four dimensions are considered equivalent, thus as spatial), don't ask Professor Everitt - an excellent physicist.. ask a person who knows that a void space has zero properties; thus cannot be "curved". Members of "a later generation" will know that a void space cannot conduct light or anything else; thus - since light goes everywhere in the universe -- there is no such thing as a void space. Either way, Luke, thank you for answering me. Goodbye. glird

If charges and masses are in motion we also must define currents and momentums, in terms of the other components of G_uv and the magnetic field. > > >< Look around you.

Interesting concept, this void space without light. Perhaps it could exist on very small scales, between the components whatever they may be that make up vacuum space (in which light can travel). However, a macroscopic object's path is not void space, as clearly light can exist at every point of it's trajectory and there are real properties of the space it travels, such as E, B, and G_uv. > Either way, Luke, thank you for answering me. > > Goodbye. > glird
