All the Myriad Ways is a collection of 14 short stories and essays by science fiction author Larry Niven, originally published in 1971. Contents "All the Myriad Ways" "Passerby" "For a Foggy Night" "Wait it Out" "The Jigsaw Man" "Not Long Before the End" "Unfinished Story #1" "Unfinished Story #2" "Man of Steel, Woman of Kleenex" "Exercise in Speculation: The Theory and Practice of Teleportation" "The Theory and Practice of Time Travel" "Inconstant Moon" (Made into an Outer Limits episode) "What Can You Say About Chocolate Covered Manhole Covers?" "Becalmed in Hell"
Not a time travel premise, but rather a parallel universe approach... for that I'd suggest The Theory and Practice of Time Travel which expresses Novikov self-consistency principle ( https://en.wikipedia.org/wiki/Novikov_self-consistency_princ...) (see also https://en.wikipedia.org/wiki/Niven%27s_laws#Niven's_Law_(Ti... ).
I'd also suggest a watch of Time Travel in Fiction Rundown - Minute Physics https://youtu.be/d3zTfXvYZ9s
If you want something longer on the subject, then Timemaster by Robert L. Forward is a good book to read ( https://archive.org/details/timemaster00forw/page/n11/mode/2... ). It begins with:
> There exist semieducated but obstinate people who have raised the concept of strict local causality to godhead, and attempt to use such words as "obviously" and "it only makes sense that . . ." in an attempt to "prove" that their version of causality cannot be violated, and that any sort of time machine is logically impossible. From my reading of the scientific literature, they are wrong. If I receive a letter from this sort of person complaining about the "impossibility" of the time machines in this novel, I will throw the letter in the nearest wastebasket . . . unless the letter is accompanied by a reprint of a scientific paper published in Physical Review (or any other reputable, refereed scientific journal), written by the person writing the letter, which proves that the paper "Cauchy Problem in Spacetimes with Closed Timelike Curves" by Friedman, Morris, Novikov, Echeverria, Klinkhammer, Thorne, and Yurtsever, is erroneous.
You'll note that history in that story remains consistent... and you can't kill Hitler.
