The Support Problem. What supported the canopy?
A Vapor or Liquid Canopy. A vapor canopy would rapidly diffuse through the atmosphere. Once the vapor contacted the earth’s surface, it would condense. A liquid canopy would quickly evaporate and then diffuse through the atmosphere. Neither type of canopy could have survived for the many centuries before the flood. An Ice Canopy. An ice canopy would vaporize into the vacuum of space, just as dry ice vaporizes at atmospheric temperature and pressure. Furthermore, ice is structurally weak. An ice shell could not withstand tidal stresses or meteoritic or asteroidal impacts. A spinning ice shell would not be able to withstand the powerful centrifugal forces at its equator and the crushing gravitational forces along its spin axis. More dramatic yet, a solid ice shell, spinning or stationary, would crash into the earth. Imagine an arbitrary object anywhere inside a hollow, spherical shell. Every particle in the shell acts gravitationally on the object. Sir Isaac Newton showed that the sum of
