How forces work:
Theres the dark forces and light forces with all persistant and guide
your destiny.
They push against each other yet somehow balance out.
With enough of the dark forces you can choke people you deem
incompitent, or shoot lightning from your hands.
I hope that helps answers the questions.

One of the replies to my question on StackExchange was that what
really mattered was that something is accelerated. Since
acceleration is really(?) a matter of a change in energy of the
thing accelerated, perhaps the most fundamental interaction is the
transfer of energy from one entity (whatever an entity is) to
another. Do we have any reasonable way to talk about how that happens?

Along the lines that Lee is mentioning with fields being the first
class objects, Bruce Sherwood may be able to illuminate some
of the
current thinking in Quantum Field Theory and how
interpretations are
made with respect to forces.
Bruce?
