Time for some trolling. xD
Definitely doing that for Harry Potter books lol, fuck that author (she who shall not be named).
Best let them come up with the idea, then you publish it the next day, and watch the author’s reaction:
“Someone has already published a book on the same idea? Nooo wayyy!”
[Insert “U Mad Bro” Trollface Meme]


That’s kinda why I think time travel is impossible, if it is ever invented someone will go back and invent it sooner, then someone will go back again until eventually it ends up being the first thing ever invented by humans.
Maybe time travel requires a receiver to send to? This isn’t my idea, but I don’t remember who came up with it. I don’t believe that’s possible either, but that would explain why we haven’t seen any travelers yet and still keep time travel a theoretical possibility. You can never travel further back in time than to the invention of the first time machine.
There was a theoretical one I saw ages ago that was a giant cylinder rotating in space at close to the speed of light that had this limitation. I remember exactly zero details beyond physically what it was in the phrase “time cone”.
Seems like it’s probably the Tipler Cylinder
Plot twist: The first time machine HAS been invented, but the creator thought it was a failure because there was no previous machine to transmit to.
Primer
I watched a YouTube video about the plot and showing which timelines were where and it hurt my head lol
Haven’t seen it, but it might be the source nevertheless.
