Hawaii offshore and comets with gravel

1 Mar 2012

At www.physorg.com/print249588620.html we learn that a submersible has discovered that deep canyons off the coast of Hawaii link up to river valleys. Detritus carried by the rivers enters the canyons and supports a rich variety of marine life. Does this mean more of Hawaii was once above sea level?

At www.io9.com there is a post that says comets possess an 'atmosphere', if that is the right word, that consists largely of gravel - shades of Velikovsky.

Over at www.jpl.nasa.gov/news/news.cfm?release=2012-052&cid=release_2012-052 there is a report of astronomers spotting young stars flickering in the middle of clouds of gas and dust (for image see www.nasa.gov/mission_pages/herschel/multimedia/pia13959.html).
