- Pebble accretion and the early Earth
It is being reported in the press that there is new evidence for pebble accretion models https://www.bbc.co.uk/news/science-environment-51295365
Normally when we think of the very early Earth we think of being formed violently . This model seems more gentle. I am wondering what that means for the appearance of the night sky on the very early Earth. As I understood it, if one stood on the early Earth it wouldn't be possible to see the night sky because of 1) the debris of the early impacts and 2) the vaporisation of water from violent impacts . However if this new pebble accretion model is correct would that still be so. Would the view fo the night sky be blocked out ?
