Sandokhan, may be you could teach us how to create your "ether" in a laboratory, and how can we measure the refraction on it.
Please refrain to post a bunch of links from theflatearthsociety.org because I open none, it doesn't make any sense.
Explain in your own words how to conduct such lab experiment, in a clear, concise and practical way, avoid to be verbose about what makes no sense, please.
We are trying here to conduct an investigation about Jupiter, size, satellites, distances, orbital numbers, etc.
You mislead the conversation very easy to other factors, now Sirius, as if it would explain the shadow of Jupiter moons.
