Accretion outside a gravitational body is effectively falsified. This means the nebular disk theory, core accretion model and planetesimal theories are false.
The real Pseudo-astronomy/astrophysics are the core accretion/nebular hypothesis/planetesimal models which have accretion outside a gravitational body. Outer space is just too violent to form anything coherent absent something really hot and big clumping matter together. Accretion happens inside of stars, as star evolution is planet formation itself.
