Mike (Michael) Twichell is an engineer, gravitational theorist, author, painter, musician, song writer, cartoonist and all around super guy.

Mike is the author of "Aether Gravity" - the gravitational theory of the century.  The theory dispenses with current empty-space thinking, and applies the full space model of the aether to explain gravity. 

The following two postulates by Twichell explain the theory:

1.  Matter absorbs aether

2.  Bernoulli's Principle applies
