dumb thought: I was thinking if it is possible to beam info into space/somehow have the backdrop return it. Doesn't make sense, you'd need to know the formula/changes with space as it expands but yeah. I'm not literally talking about radio waves or something. I mean to use space as a medium to write on but "how". As in you send light to specific things that would return it and account for shift/losses over time.
