Why don't electrons turn into black holes?

AI Thread Summary
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.

From my understanding electrons are point particles with zero volume, therefore zero radius.


F = GMm / r^2
F = GMm / (0)^2
F = ∞ N.


Can someone please explain?

A point particle doesn't exert a force on itself. That formula only applies to two different particles.

In a broader sense, though, we really don't know why. You're right that treating electrons as point particles causes all sorts of problems. Their true nature is still somewhat mysterious. (This is/was the appeal of string theory, that the fundamental particles could be "strings" or other extended objects rather than points, which helps a lot of problems go away)
 
Because its Compton wavelength is bigger than its Schwarzschild radius.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
