—where the star is the oversized baby of the system, with the gas-giant planet as its older progenitor. The discovery of gas-giant exoplanets in low hot orbits falsified the core accretion standard model of giant planet formation, but the theory was rescued by appending the ad hoc secondary...

Gneissic continental basement rock is suggested here to be extraterrestrial in origin, from aqueously-differentiated hot-classical Kuiper belt objects (KBOs), with terrestrial emplacement during the late heavy bombardment (LHB), circa 4.2–3.8 Ga. An alternative solar system formation mechanism...

Surely the simplest and most intuitive DM candidate is a primordial concentration of hydrogen and helium, and surely the most intuitive explanation for the radial acceleration relation (RAR) is the interconversion of luminous and dark versions of baryonic matter, dependent on the local radial...

One needs to make allowances for the possible survival of a tiny fraction of an interstellar bolide, almost regardless of its entry velocity. Atmospheric ablation of a meteor is not a homogenous process where you merely compare the specific kinetic energy of the meteor vs. its specific...

A star will centrifugally fragment long before reaching light speed rotation, which would be true even for compact stars like white dwarfs or neutron stars. Here's what happens when a hydrostatic object spins up to the point of centrifugal fragmentation, which I suggest has actually...

This is one more piece of evidence supporting a relatively-recent, 650 Ma, massive, high-angular-momentum debris disk in our highly-unusual solar system: - Anomalously warm moons of Jupiter - Marinoan glaciation on Snowball Earth - Low large-crater count on Ceres, with an internal ocean, in a...
