''you seem to have a cast-iron idea that unless something is not seen or recorded in some ways then it cannot be accepted''
It can be considered. It can be explored. But without evidence it remains an idea....however interesting and appealing it may be as an idea or concept.
''How about gravity waves that were postulated at least 40 years ago--now understood''
Of course; postulated is correct.
'Einstein's theory of relativity needed to be incorporated into the algorithms before a GPS will be accurate--not understood for almost a century''
Yes. First it was considered as an explanation for problems in physics and cosmology, then proposed, mathematical modeling, then physical testing,, followed by confirmation. Which has stood the test of time, with many researchers trying to find flaws in relativity.
