Is there anything in the universe that cannot be compressed?

Is charge point-like or a smear?

How can electric field be defined as force per charge, if the charge makes its own, singular electric field?

How can neutral atoms have exactly zero electric field when there is a difference in the positions of the charges?

Can the center of charge and center of mass of an electron differ in quantum mechanics?

Doubt with Relativistic Lagrangian Expression

How to find a particle's dynamics in general relativity?

Why does it make sense to talk about the first-quantized BRST formulation of a relativistic point particle?

If particles are points, then aren't atoms empty space?
