An act of faith is expressed in this statement, as we are unable to go
there and make tests. We are not able to acertain that other effects
are taking place that hide what is going on. Any assumptions are
matters of faith.

An interesting statement, testable and untestable. Again an assumption
is being made as to the testability of something. If we can't test it,
it is not testable. If we create a test but can't perform the test,
does this make it science or faith.
