15 - Accretion



The general understanding seems to be that all these systems either formed differently to our own, or experienced some kind of turmoil in their birth.

However, with so many examples of systems behaving in ways that suggest that they formed differently to our own, I feel it is more likely that the general understanding of how our system formed is wrong. At the core of this is the idea of ‘Accretion’ as the main process in planetary formation, which shows all the celestial bodies of our system forming in tandem from an original cloud of interstellar gases, and forming in generally fixed orbits. In 'About This Site' I have outlined how the questioning of this process is a key element within my overall hypothesis.

'Accretion' can be defined as; growth or increase in size by gradual external addition, fusion or inclusion. Or more specifically in Astronomy as; an increase in the mass of a celestial object by the collection of surrounding interstellar gases by gravity.
