A New Theory of the Earth the flood. He asserted that the Earth was originally a comet, which God formed from its initial "chaos and void" into a habitable planet. He also argued that the flood itself was caused when the Earth passed through the tail of a comet, which, it was known by that time, are composed largely of water. His analysis was very detailed, and similar ideas were promoted in the 1960s by other creationists postulating causes for the global flood, along with similarity to the ideas of Immanuel Velikovsky. However, many of them are in direct conflict with contemporary scientific understandings; and comets
Void (composites) void content of approximately 1% is appropriate for performance while other grades of composites can have between 3%-5% void content. A small change in the percentage of void content may not seem like a large problem however for a loaded carbon fiber laminate composite, a 1%-3% increase in void content can reduce the mechanical properties of the composite by up to 20% Void content in composites is represented as a ratio, also called void ratio, where the volume of voids, solid material, and bulk volume are taken into account. Void ratio can be calculated by the formula below where e
