Since this is all speculation anyway.
A supernova is caused when a star looses mass to quickly and is incapable of supporting itself, thus exploding. It has already been observed that an entity with a comparatively small surface area can have be incredibly dense, i.e. neutron stars. Could it be argued that it is possible for an infinitesimal particle of infinite mass could have at somepoint existed and suffered what would have been the equivalent of a supernova? Ejecting its mass and setting about the universe.
