Hydroplate theory is a scientific model that explains the events surrounding the world-wide Flood described in the book of Genesis, and shows how these events affected not only the entire planet, but also the whole solar system. The theory was first developed by Dr. Walt Brown in the 1980s in his book, In The Beginning; Compelling Evidence for Creation and the Flood. Over the years, Dr. Brown has continued to add new details to the theory and it is now in its 9th edition.
