@rosborne979,
Yep, Sometimes the machinry isnt built to do th job and mot of the time we blindly stumble on things that work it out.
It was just like the time that boat toed magnetometers(used to locate mines couldnt detect changes on the earths magnetic declination over great distances until they came out with the mega gaussian drivers to hunt for deep mines that they were getting huge mag interference signals that were actually caused not by mines, but by deep ocean magmas reaching a curie point wrt the planets magnetic field. Accidently the minesweepers discovered evidence for the Wegner Hypothesis called continntal drift.
Also like Penzias an Wilson having to cleam out the pigeon **** from their "space horn" and gaind some evidence of the Big Bang
