Time Travel Systems™ (TTS) extends the Second Law of Thermodynamics by adding a time element. TTS assumes that systems will tend to configure themselves in a manner that maximizes the rate of entropy production. This assumption can be called the e th Law of Thermodyanamics, or fast entropy.
Fast entropy can then be used to create models of, simulate and forecast business growth curves, industry growth curves, and business cycles. More specifically, a methodology based on fast entropy is used to simulate and forecast resource production and use, business and product growth curves, and overall economic business cycles. This method considers actual physical data rather than relying solely upon mathematical modeling. Past historical regimes can be modeled as well.
