Wow, going Sci-fi now.
I revive this thread with a theory i've long made: Absol's law of Chronometry (
http://fav.me/d4if376)!
For those who don't want to link outside, i'll give summaries here.
Law #1: Time passes subjectively
Law #2: Time will only pass forward
Law #3: Every person will be treated as a separate entity
Law #4: Every single entity live in its own time, and in its own world
Law #0: No one can prove the Laws of Chronometry. Not even the creator of the laws.
Law #-1: There will exist AT LEAST one world where these laws doesn't work
Science fiction has always depict time traveling as something grand, something impossible. And with it, comes the time paradox: grandfather paradox, information paradox, and such. Like they did in Back to the Future: "don't meet yourself". As such, I'm here to set the laws for my own verse's time travel (if there's any).
Law #1: Time passes subjectivelyTime will keep moving forward at constant rate according to YOUR perspective. This means that not everyone experienced the same time passed as you. For example, you will never figure out whether your neighbor has lived for almost 200 years, because YOUR time only passes for around 20 years. Only you will experience what your time feels like.
Law #2: Time will only pass forwardIn your perspective, time will always pass forward. Even if you go back to the past, it will still count as YOUR future (not anyone else's, hence #1). This makes it possible to, say, invent a time machine to go back to your past and kill your younger self. See, because you kill your younger self NOT in the past, but in the future (which shaped like the past).
To simplify, it's like this:
past --------------------------------------------------------> future
^build time machine ^go to past ^kill younger self
and NOT like this:
past --------------------------------------------------------> future
^kill younger self ^build time machine ^go to past
^<----------------------------------------------V
Time moves forward subjectively, so rather than actually go to past, you will go to future, which will looked like your past. You murder your younger self in the future, not in the past. Thus, your current self is not affected.
This also explains why you don't get younger when you go back in time. Because your time still moves forward, even if it looks like going backward.
Confused? This is the hardest part, so you should be. Just try to understand it.
Law #3: Every person will be treated as a separate entityThere is no single you. There are current!you, and past!you. They are 2 different entity, irrelevant to each other. It's like you move to other world and find someone who looked like you. You're not him, and he's not you. So current!you killing past!you in the future won't bring any disaster to current!you (except for murder charge, but that's another story)
In the same notion, killing past!father will NOT prevent current!you from being created. Nor can you kill current!father BEFORE you're born, because current!you did not exist back then. Consequently, future!you may come and kill current!you, and bring no harm to future!you. Destroying your time machine will NOT prevent this, because current!your time machine and future!your time machine is a DIFFERENT entity.
Which bring us to our last law.
Law #4: Every single entity live in its own time, and in its own worldWhen i said "we are the god of our own world", i mean it LITERALLY. You can kill Bob, but you can only do it in YOUR world, and in YOUR time. In Bob's time, however, he will live. He will survive the murder. He may even get his revenge (and succeeded). This explains our last question, "how can we still live if we're killed in our younger self?". Because when current!you kill past!you, you only kill it in current!you's time and world. Past!you will still live in his time and world (in this case, past!you is yourself, just another name used to denounce it). Think of the concept of parallel universe. This law is just like that.
And those are the 4 main laws. But we still have 2 special laws
Law #0: No one can prove the Laws of Chronometry. Not even the creator of the laws.Why? Because this is a speculative work, and people have yet to invent time travel.
"If this law can't be proven, how do we know it's true?" By observing the stability of time around us. Admit it, time is stable, and moving at constant rate. Which will never happen if not for this law. The mere existence of time proves the laws to be true.
Law #-1: There will exist AT LEAST one world where these laws doesn't workParallel universe theory says that there are infinite universes out there, each with their unique rules and entities. For every rule given, there will always be at least an exception. If this is true, then for these laws, there will be at least an exception too, because laws are rules. Which explains the law #-1.
These rules are SPECULATIVE WORK, based on my own imagination and thinking. Credit me if you wish to use these laws.
If i found you using this without permission, I'll make sure to find your current self and kill you to remove you from MY world. Because we are the god of our own world.
