Main Question or Discussion Point
It is fairly evident the universe originated in a more highly ordered state than we presently observe. It is also fairly evident it has become increasingly disordered over time [e.g., expansion and those inexplicable clumps of matter called galaxies, stars, etc.]. I am therefore forced to conclude the number of possible states of existence have increased over time. The concept of action and reaction [blame Newton and Laplace] seem to insist current explanations for gravity and entropy are incomplete. I am very uncomfortable having to rely upon untestable explanations. Strings and extra dimensions are not very satisfying. They appear to require a higher order of 'law' that is inherently impossible to validate by observation. The long and the short of it... a universe without predictable consequences [causality] cannot exist in my local reference frame.
