You're just about to go to sleep when BOOM! you hear a loud bang outside and see a big flash of light. You go out back and see some sort of machine. You go inside of it and determine it's a time machine of some sort. A voice prompts you to say when you want to go. Where and when would you go?
The butterfly effect is The butterfly effect is a common trope in fiction when presenting scenarios involving time travel and with "what if" scenarios where one storyline diverges at the moment of a seemingly minor event resulting in two significantly different outcomes.-Wiki
So if i interpret this correctly in life everything you do no matter how small there are 2 differnt possiable out comes and by changeing one out come it goes to the other.
Now a theory is if you go back in time and kill someone or something or do anything that wasnt done befor that action can have a drastic out come on the future.
Honestly, I would want to go back/forward in time to prevent the machine from ever being created. Time travel is a thing I believe would be too dangerous to mess around with. Even simple observation.
Of course, if I prevented it from happening.. Blah blah blah, time paradox, blah blah.
I would.. err.. go back to when I was 13, and start that bit again, and listen in school instead of fuking up
What I would have given for a second chance at so many things.. *sigh* Personally, things are better now; I honestly wouldn't change them for the world. Besides, one can never be sure what might have come about if things were different.
