Time travel movies are always full of bad physics and and contradictory logic, though certainly some do it better than others. I usually just try not to think about them too hard so that I can take in the entertainment value. Looper (streaming|DVD) is no exception, but the most glaring error in the movie’s science was not in the physics; it was in the biology.
The beginning of the movie tells of a new mutation, the “TK mutation”, that has crept into the population to give people weak telekinetic powers. The idea of a gene, and more importantly a mutation in an existing gene, somehow allowing telekinesis is of course absurd, but that isn’t what I’m talking about.
I’m talking about the allele frequency. The movie takes place in the 2040’s. Only thirty years from now. And, at that time, the movie says that 10% of the human population has the TK mutation. This frequency is fantastically improbable.
Why? Well, right now 0% of the human population has this mutation. The thirty years between now and then have to bring that to 10%. That sounds impossible – let’s see if my suspicion is correct.
The key to understanding how one can figure the origin of the universe is in origin science. Evolution is origin science, which is science that tries to explain the origins of the earth through studying written history and physical evidence from ancient past.
Evolution does not try to explain the origin of the earth. It tries to explain the origin of biodiversity.
Operational science includes the discovery of information through experiments that are done today. Evolutionists have tried to prove evolution through operational science, like in Miller’s experiment (Ham and Mortenson 24).
Again, this type of experiment only supports specific hypotheses, not the theory of evolution. But otherwise you are correct; scientists have tried to prove evolution through “operational science.” And have been successful (look into evolution of pesticide and antibiotic resistance). Probably the greatest and most obvious example of all, however, is dog breeding. This is essentially a grand experiment done over thousands of years that has brought the original wolf ancestor to exist as one species with forms as diverse as a chihuahua and great dane. And this experiment wasn’t even done on purpose!
Which probably requires that I add this note: natural and “artificial” selection are the same thing. We call it artificial when it is done by people. So “natural” selection is when the environment selects for/against certain traits, and “artificial” selection is when the environment that does the selecting is controlled by people (in other words, an experiment).
Evolutionists claim that evolution can be seen in modern society, but this “evolution” that we see is mutations—a loss of genetic information, rather than a gain in genetic information that evolution requires (25).
