I was wondering if we could have an object made up of only electrons. Normally, that wouldn't be possible because electrons repel each other. However, this repulsion can be overcome using gravity. So my question is, how many electrons would you need to have their gravitational attraction overcome the electromagnetic repulsion and form a stable object? Or perhaps is the charge-to-mass ratio of the electron such that the electromagnetic repulsion will always be higher than the gravitational attraction and thus preclude such an object?
Of course, an object like that would not form naturally since the electromagnetic force has the tendency to self-limit via neutralization. So for our purposes, we assume that there aren't any positively charged particles nearby to neutralize our object. There are only electrons.
