Are we rewriting the birth of the solar system?

AI Thread Summary
The discussion centers on the potential reevaluation of solar system formation theories, referencing a 2004 study by D. V. Reames and C. K. Ng on heavy-element abundances in solar energetic particle events. Participants express curiosity about the dual theories of solar and planetary genesis: one involving a shock wave from a supernova and the other focusing on gravitational accretion of solid materials. There is a suggestion to consider a model where the sun forms through solid accretion, similar to planet formation, leading to a solar ignition event. This perspective raises questions about the traditional understanding of solar formation processes. The conversation indicates a desire to explore alternative theories that could reshape our understanding of the solar system's origins.

What is going on? Are we rewriting the birth of the solar system?

I haven't read the reference but I'm going to the library right now.

I've always wondered about the apparently two separate theories regarding the genesis of our sun and the planets... those being that the sun was formed when a shock wave from a nearby exploding star compressed the gaseous nebula that once was and that the planets somehow managed to coalesce from weak gravitational accretion of solid material. Why not start the sun from the accretion of solid materials and go through a similar birthing experience as that for the planets. Accretion of solids leading to accretion of gas, a solar 'iron catastropy' resulting in its ignition resulting in a sun with an iron core?
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
