Since when does an object (any object) have a zero mass?
Anything that exists has to have a mass to it.
Just asking?
*Note: I'm an interested layman, not an expert*
Particle physics is just rife with particles which seem to defy all logic these days.
Some subatomic particles perhaps have radiated energy from a parallel universe, thus having the entirety of their mass separate from their force, or at least it would appear that way from our universe.
Gravity works much like that- gravity, under anything like predictable models, should be almost five times stronger. All other forces dwarf gravity, so one of the leading theories is that the particle known as a graviton is actually delocated, and what seeps through to our universe is just the leftover energy.
The recently discovered Higgs-Bozon particle may have a field which almost all matter interacts with. This interaction could possibly be responsible for the behavior of mass.
As to the OP? Does god exist? I know Einstein believed in god- not a god we knew, but a god we could hope to learn more about. That sounds about right to me.
