Well, folks, this is an epic comic of epic length by American Captain standards. I don’t know what I was doing, I guess I just really didn’t want to work on my thesis.
I hope the way I have posted it will work, but bear with me if it doesn’t - I have a…
I feel like you’re right, in that Marvel Time has to be nebulous because it’s better that way - for all intents and purposes Cap has been de-iced for ten years, but he was also around in the seventies. Tony trod on that landmine/shell/whatever in… probably 2003 now… but if he has to have watched the moon landing as a kid for a story to work, then he did. If the FF need to have made their space trip in 1963 for a story to have thematic resonance, they did. Theme trumps any ‘realism’ a sliding timescale can provide.
I feel that’s a superior tactic for dealing with what is basically a problem unique to long-running corporate-owned fictional universes than DC’s ‘Crisis Crisis Crisis ALL THE TIME FOREVER’ strategy - Marvel Time is soft and bends moment to moment, DC’s is hard and periodically breaks and has to be glued together haphazardly.
