Biologist Wayne Rossiter on Joshua Swamidass’ claim that entropy = information
|March 16, 2017||Posted by News under Information, theistic evolution|
Swamidass surprises us with a very counter-intuitive statement:
“Did you know that information = entropy? This means the 2nd law of thermodynamics guarantees that information content will increase with time, unless we do something to stop it.”
Of course, he is arguing much more than just the observation that entropy = information. He’s arguing that the 2nd Law of Thermodynamics guarantees an increase in information. This seems very sloppy to me. Yes, if we consider time as a variable, then the universe will develop pockets of increased information (complexity?), while still experiencing a global loss of information and complexity. The universe putatively began as a maximally dense, maximally hot locus. As it expands, heat and potential energy will dissipate, even if locally, structure and information emerges.
In some ways, Swamidass’s argument sounds similar to that of Lawrence Krauss (a devout nonbeliever). Swamidass is basically arguing that the universe begins at maximum energy, but minimum complexity (no information-rich structures, just the simplest atoms–hydrogen and helium). It then moves through stages of more complex (information-rich) structures, even as it loses available energy. It then ends largely as it began, and those complex structures reduce and decay back to a uniformly distributed universe, devoid of free energy, and the universe becomes a “sparse soup of particles and radiation.”It emerges as simplicity and ends as simplicity.More.
If Swamidass (or any similar person is funded by Templeton), he can argue anything he wants, including any form of fake physics. Making sense is optional.
Sorry, gotta go fill up another trash bag full of suddenly appearing Boltzmann brains … Quite the plague this year.
