Does a single elementary particle in motion exhibit inertia?

[Michael F. Dmitriyev]

Consider this thought experiment. If only one object existed in all the universe and it was moving would it have inertia?

If you speak a word "universe" then it means existence of all attributes inherent in it.
This is the space, time, gravitation, light and … at least one black hole in the center of this universe. Without each of this “component” existence of universe and object (mass) itself is impossible. Then, what is your question ?

 

[HallsofIvy]

Stick to the topic there is nothing mentioned about dividing. Just answer the question.

He did answer the question. You're just saying that you don't like the answer!

I think Timetraveldude question is not well set. The only "unique object" possible is an elementar particle. In this case the question has no sense because there could never be inertial effects. To have it, we should demonstrate that it is not adimensional and it can rotate (not the quantistic spin, of course).

All other objects are formed by more than one particle, so there can be inertial effects.

I think I would probably used the following question instead: "Given a universe with just one elementar particle, the total energy of this universe is greater than zero?" and I think the anwer is "no"

Does this elementary particle you talk about have size?
