Right. Measuring something is not any kind of definitive evidence. Scientists make measurement errors all the time. If it can’t be demonstrated, replicated, and eventually put into practical use, it might as well be fairy dust we are talking about.
I work with sensitive instruments, though nothing like what these guys probably use, so I have some idea of the challenges associated with calibration, vibration, temperature and humidity changes, static electricity, etc., etc.
It is not nearly as simple as most people think to make extraordinarily precise accurate measurements. In fact, most digital devices “lie” to people.
For instance, I have a digital hygrometer (relative humidity) that reads out in 0.1% increments. Which leads the average person to think it’s accurate to 0.1%.
In fact, it is actually only accurate within a plus or minus 2% range. And that’s from about 20% to 80%. Above or below that middle range the accuracy drops off quickly. And the 2% assumes recent calibration.
I believe the same is true of many instruments.
