While looking thru a notebook of mine, I found the following text. It's probably utter utter physics crackpottery, but I'm throwing it out here anyway.
an idea about the nature of inertia
avoid action at far distance
every real particle is surrounded by a swarm of virtual particles
virtual particles have same velocity as "parent"
if parents v vector changes, virtual children have to live longer / work harder to recombine
had to write it down before i forgot it
should have dated it. this is 20040703
