I’d time travel back to about 1995 with a list of stock tickers and dates…
Or…
I’d travel so far in the past that it actually became our future in 20 years and come back with a sports book of all the sports winners for the next 20 years.
I’s go back and tell younger me to buy Google and Apple stock, and buy some Bitcoin when it was around $1.00. I would then be rich enough to buy all the crap I don’t need on Woot!
This is THE best answer! Going to 4/14/1865, is tempting, but so far back as to risk a plethora of unimaginable negative outcomes. Going to 1963 to continue a time of great hope almost certainly outweighs the risks.
If I was going back only as an observer, as opposed to stopping assassinations, divulging lottery numbers, etc., seeing dinosaurs would be the definition of “incredible.”
Time travel will be through the unconscious mind like a movie you get to live through again unable to speak or act differently until the end of this timeline as we know it without time travel outside of the mind. Wherever we are in the the closed loop is where “we” stay but travelers may come and go.
