Electrons are considered point particles with zero volume, leading to confusion regarding gravitational force calculations, particularly when applying the formula F = GMm / r^2, which becomes infinite at zero radius. However, a point particle does not exert a force on itself, making this formula inapplicable in this context. The true nature of electrons remains uncertain, contributing to various theoretical challenges in physics. The appeal of string theory lies in its proposition that fundamental particles could be extended objects, potentially resolving these issues. Ultimately, the relationship between electrons and black holes is complex and not fully understood.
