It appears that ball lightening is a contained ball of this stuff surfaced with hot electrons held neutral on the surface. They are not flying apart at all. And like hydrogen, it can pass through solid walls. We do not store hydrogen very well. Obviously a whole bunch of problems in physics change when we start working with this model. Yet so far it all conforms to observation. Understand that in vsuch an universe, opening a void actually does two things. Space is created allowing new matter to be created in order to fill that void. This is posited to look like an inner sun. There is also a boundary event happening as well, both inside and outside the boundary and both involve gravity compression of the neutral neutron pairs. We no not know what actually occurs, but spontaneous matter creation appears plausible
