Just because we don't have the technology at the moment doesn't mean the theories can not make predictions. We have the technology , and the concepts to be able to test much of QM (just not a qm/spiritual realm interface).
There were items that the theory of relativity predicted that we had to develop the technology to be able to test. That did not mean that relativity did not make those predictions.
QM has made a number of predictions. Many of those predictions have been confirm on many different tests.
The ekuropic universe model makes a prediction that is different than the standard inflationary bb theory. We don't currently have the techology to do the test, but it is possible to do those tests.
ID does not make any predictions. It does not have any explanitory power. The mechanism that Randyman is proposing doesn't seem to be
have a testable mechanism. (I will be waiting to hear his propsosal though).
It might not be wrong, but until we have a method where it can be demonstrated, tested, and possiby falsified, it isn't science yet.
