I am not sure whether some interplanetary amino acids were found or not on some asteroids or comets in solar system. Had spacecrafts collected samples of complex organic molecules ? Or some spectra for complex amino compounds on comets were discovered ? Amino acids were already found on some meteori...

Does "ionized" mean there are no electrons flying around them? I guess there should be enough electrons around the ionized elements, just flying FREELY. :roll: :roll: :roll: All solid metals (including iron) have their "outer" electrons in a metallic orbit. They are free "floating" and this explain...

There is no need to "split" the atom/nucleus of iron. Protons, neutrons and electrons exist in iron atoms all the time . In the core of stars most iron nuclei are highly ionized. Probably iron nuclei are orbited by few electrons only. Once protons and electrons recombined under strong gravitational...

There is no need for a massive star to form a neutron star BEFORE going into the blackhole stage. pts such as one in a neutron star, protons and electrons cease to exist as they have combined to form neutrons In such a case, chemical elements (or nuclei of atoms, which must have protons) cannot exi...

I am not sure what the basis of your speculation is. The process is that, under tremendous gravitational force, electrons and protons combined to form neutrons. To form neutrons, these electrons and protons are origin from the materials of the previous star. Probably there are large amount of iron ...
