I know I used to understand it

I know I used to understand it, but it’s a while ago now and while yes, I can say that the speed of light in a vacuum is constant regardless of the motions of the source and observer, I’m not sure if that constitutes an explanation. Also, isn’t it that the speed of light in a vacuum is constant regardless of the motions of the source and observer only if they’re in the same frame of reference, where that means that they’re not accelerating at different rates. Something like that. I think this goes to show I need to swot up.
