Thanks Ptera, there seems to be some changes in how scientists think about science. Is the multiverse science? What about M-theory? They propose ideas that are untestable. There is much in quantum physics that presents some of the same problems. That's why highly regarded scientists like Lee Smolin and Peter Woit have rejected a lot of what goes on in physics today as beyond science. I note that Sean Carroll, well known physicist and writer of Something Deeply Hidden wrote an article about how Popper's falsifiability idea of science had to be rejected. It seems part of this kind of effort is to justify as scientific and rational ideas and directions that may exceed the traditional definitions and understandings.
