Hi nightbat "FIELDS" That's the rub. Fields that give friction to inner
space(Planck space) Always liked Hawking's definition of
a field.It went like this. "Something that exists throughout space and
time,as opposed to a particle that exists only one point at a
time".(profound (yes) Funny thing nightbat I can't remember reading
how "string theory" uses fields??? Hmmm. Well I use Fields in a lot of
my thinking in Planck spacetime,and yet I leave out any field or wave
when thinking gravity. Go figure Bert
