AI Thread Summary
An object with zero mass and zero inertia would not be considered an object in the traditional sense, but rather a form of free space. While it may seem true that such an entity could move spontaneously in any direction, the concept of force only applies to objects with inertia. Therefore, the idea of movement without an applied force is not strictly accurate. The discussion highlights the complexities of defining movement in relation to mass and inertia. Ultimately, the nature of such a zero-mass entity challenges conventional physics.

Is it true that if an object has zero mass, and zero inertia, it would move spontaneously in any direction without an applied force?

It wouldn't be an "object" would it? It'd be free (n-dimensional?) space I think.
 
yes, in a way it is true, but forces by its very definition applies only to inertial objects so it isn't really that the object can move without an applied force, strictly speaking.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
