# How: Total mass and Inertia?

This has been bothering me recently, so here goes…

Does the total mass of the universe determine the locally measured initial reaction of masses subjected to acceleration, and if so, how does it couple instantaneously, and if distant matter does not cause local inertia, what does?

Yes, afaik.

how does it couple instantaneously

How does…mass…couple instantaneously? Fission :) That’d be one way, another would be the coupling of “too much mass” and you get a sun (aka, star)…unless I’m missing something?

if distant matter does not cause local inertia, what does?

“Distant” is a relative term, no? The greater the distance, the larger the force has to be for such force to have an impact on a nearby object…for example: our sun gives us light and heat but, other stars only give us light, as they are too far away for their radiant heat to have any energy transference to Earth.

So you can say that local matter must be the cause of any local inertia…unless there is a force strong enough to exert it’s influence locally from a larger distance.

Does that help?

Jeremy,

Thank you.

from what I know, I wouldnt think so, but the second part of your question I dont know

Seems I’m doomed to ponder.
