The Fantasy of Ungrounded Physics

As a follow-up to my last post about Darwinism's bad week, I also ran across this story ... an interview with South African Physicist George Ellis about the philosophical inanity that is regularly spouted by the New Atheist priesthood. Keep in mind that Ellis is not some easily dismissed Christian minister or Intelligent Design proponent (though I obviously have no problem with either of those). The article is from Scientific American and Ellis has co-authored books with the likes of Stephen Hawking.

From the piece:
Horgan (SA Interviewer): Lawrence Krauss, in A Universe from Nothing, claims that physics has basically solved the mystery of why there is something rather than nothing. Do you agree? 
Ellis: Certainly not. He is presenting untested speculative theories of how things came into existence out of a pre-existing complex of entities, including variational principles, quantum field theory, specific symmetry groups, a bubbling vacuum, all the components of the standard model of particle physics, and so on. He does not explain in what way these entities could have pre-existed the coming into being of the universe, why they should have existed at all, or why they should have had the form they did.  And he gives no experimental or observational process whereby we could test these vivid speculations of the supposed universe-generation mechanism. How indeed can you test what existed before the universe existed? You can’t.

Thus what he is presenting is not tested science. It’s a philosophical speculation, which he apparently believes is so compelling he does not have to give any specification of evidence that would confirm it is true. Well, you can’t get any evidence about what existed before space and time came into being. Above all he believes that these mathematically based speculations solve thousand year old philosophical conundrums, without seriously engaging those philosophical issues. The belief that all of reality can be fully comprehended in terms of physics and the equations of physics is a fantasy. 
... 
Horgan: Krauss, Stephen Hawking and Neil deGrasse Tyson have been bashing philosophy as a waste of time. Do you agree? 
Ellis: If they really believe this they should stop indulging in low-grade philosophy in their own writings. You cannot do physics or cosmology without an assumed philosophical basis. You can choose not to think about that basis: it will still be there as an unexamined foundation of what you do. The fact you are unwilling to examine the philosophical foundations of what you do does not mean those foundations are not there; it just means they are unexamined.Actually philosophical speculations have led to a great deal of good science. Einstein’s musings on Mach’s principle played a key role in developing general relativity. Einstein’s debate with Bohr and the EPR paper have led to a great of deal of good physics testing the foundations of quantum physics. My own examination of the Copernican principle in cosmology has led to exploration of some great observational tests of spatial homogeneity that have turned an untested philosophical assumption into a testable – and indeed tested – scientific hypothesis. That’s good science.
If this kind of common sense reasoning about the origin and nature of all reality interests you, I would also suggest an excellent book I read earlier this summer by the atheist, materialist philosopher Thomas Nagel, who has insulted the Priests of Scientism by having the unmitigated gall to question their religious devotion to Darwinism. It's a fascinating read with a great subtitle ...

Mind & Cosmos: Why The Materialist Neo-Darwinian Conception Of Nature Is Almost Certainly False

Enjoy!
