I don’t hate it. It makes room to tell new “old” stories without just completely dismissing canon. The idea of a “fixed point in time” is a concept that I think originated with Doctor Who. The Strange New Worlds concept is similar, but instead of a fixed point its a fixed event or fixed outcome.
I do wonder though, how much of this “time pushing back” is actually that? Or is it actually just the “Federation Time Cops” from the far future making sure things happen even if someone successfully meddles with history. I actually kind of hate the concept of time travel being a thing in Star Trek. Leave it to shows like Doctor Who.
Gorgeous! Is there any chance that you have more build details? A list of parts needed or even perhaps photos or video of your work would be great!
