Short synopsis is this: The bible talks about the firmament above, and the firmament below. In modern science we have found planets with dense structures of gas in their atmospheres. If the earth had that at one time, it would be the firmament above. A mesosphere of dense humidity sitting on a stratosphere of denser gases above a troposphere of air. There is ample evidence that the plates that the continents move on are physically separated from the core of the earth (hence they still move and we have earthquakes). The theory goes that the separation was originally a layer of water that was trapped under the plates. The flood event was precipitated by something that shattered the two firmaments."
I believe you are referring to the Hydroplate Theory, by Walter Brown. This is a playlist devoted to his theory:
Great Flood Hydroplate Theory by Dr. Walter T. Brown, PhD
The 4th video is a combined series that goes into great detail about the science and engineering supporting the theory, whereas the 3rd video is a condensed view.
Dr. Brown received his PhD in Mechanical Engineering from MIT.
