Doesn't this Red and Blue shift destroy Einstein's relativity argument? The speed of light, I am taught, should be exactly the same for all observers, regardless of their independent motion. It seems to me that you need a MEDIUM to compress the wave first. Additionally, how is it that light goes back to it's original speed after exiting say, a lens? If you take UV laser and aim it at a doubled lens, first one flat, the second spherical, the light gets reflected in a helical pattern where you can actually see the frequency change in terms of light color, going from purple to red, to green, to red, and then back to purple as it exits. Please explain!
Many questions. I'll start with the first. Actually, no. Relativity predicts the redshift/blueshift. Please watch my series on Relativity: ruclips.net/p/PLyu4Fovbph6ezYDf2FI2b8a3KMCqEr3oL&si=k2Rk_PfFTwd2Q0gt Also, please watch this one about the nature of Cosmic Redshift: ruclips.net/video/XRt4Lov9keY/видео.html As to why there is no medium for light, please see this one: ruclips.net/video/R1FMa-PTmlg/видео.html The last is one I'll let the various other viewers answer for me!

This is part of another module that I just finished remastering!

Thanks! I'll give them a watch.@@JasonKendallAstronomer
Need more luminiferous aether
It would be really nice if you could re-record this in some place that doesn't echo-echo-echo.
We only need to hear you once.
Yup. The original was much worse. I’m putting together a new set of slides for a full rework.
What an odd way of saying "thank you so very much for conveying your wisdom, for free."
