The better question you need to ask is do they really exist at all.

They are continually phasing states to hold them together.

How the hell does something that is phasing in and out of the universe care about mass.

Specifically you measure a quantum momentum because they are quantum in nature you can't lock it's position and speed.

That little quantum problem again called uncertainty principle.


So in chemistry we allow you to have atomic mass etc because in normal situations at large scale solutions it's a reasonable approximation but they are approximations make no doubt.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
