I’ll go first.
3 options
- Going back to 1964 to watch the Duke Ellington’s Montreal show. Try to meet the man and the musicians. Hang around my city.
- Go in the end of the 70s to meet my parents before they had kids. Grab a couple of beers and party with my young adults parents. See my uncles, etc. in their young time
- Going to 1881 during the couple of days when Nietzsche wrote Zarathoustra. I want to discuss with guy even if he is supposed to be writing all day long. No consequence right.
What are yours?
EDIT: I’ll clarify: You can’t affect the timeline. It means you cant go back to try to get rich with stocks, lottery, etc. It’s like going to see a movie, when you come back the world will be exactly the same. You can interact with people, but in the end, the day you spend in the past will not have existed for anyone but you, in your memories.
Is it possible to travel to the past without changing the timeline? Even going to a diner for a meal will make a ripple.
If you assume that your visit creates a different timeline than the one you’re coming back to, sure.
Back to the Future but instead of going back in time, you’re actually jumping to an alternate universe that happens to be the exact same as yours but whose time is shifted enough that the date there is the one you wanted to go to
