However even Ball Lightning nuclei are assumed to be String Knots also compressed by the outside oscillating string vacuum.
The conclusions may be many, for most cosmological phenomena, such as an exploding String Nucleus Big Bang, the Gravity pressure instead of Gravity attraction etc.etc. see: https://vixra.org/author/leo_vuyk
The origin of most of these tails are assumed to be created at the Penrose Trapped Space Horizon around Black Holes, where vacuum particles are colliding each other into real Quarks and Photon called the Penrose -Q-FFF Effect.
Below we find some examples of tail bearing cosmological objects like globular Clusters and Ball Lightning.
