cats in space explain redshift/blueshift, somehow educational AND unhinged

Someone decided the Doppler effect needed cats in space as its primary teaching tool, and honestly, it kind of works. This is the exact energy of a physics teacher who discovered memes in 2019 and never looked back. The watermark suggests this came from genuine artistic effort, which only makes the beautiful absurdity hit harder. It's cursed in the most wholesome way possible.
