I have a time machine in my garage and it works. I put an apple in it, close the door, set the timer, open the door to an empty machine, wait five minutes and the apple reappears. (Still tastes great too! Gotta love Honeycrisps.) I haven't sent anything back in time because that's more risk than I want to take on just yet.
Help me out, please. At this point, I just want to test my machine to see that it works beyond trivial examples. (To use industry parlance, I've moved beyond unit testing and want to start user acceptance testing.)
Things to test
There's a couple of things I want to find out before I put my poor fragile body into this machine to see where it goes. I don't mind testing with live animals but want to avoid cruelty to animals if at all possible.
- Is there a way for me to discover, non-destructively, how my universe will resolve or prevent any paradoxes? I'm aware that there's potential for "earth shattering kabooms" which I would like to avoid since I, and the people I care about, live here.
- Is there a limit to how far forward or backward I can go?
- Can I or anything else go backward?
- How could I tell whether I live in a multiverse, single timeline or diverging timeline universe? (This is the subject of a previous question)
- Is the past inviolate or can I remember more than one version?
I'm looking for a checklist that will help me test my time machine. I'll discover the results for myself, I just want to know how I should go about getting them. Recommendations to just destroy that machine will be flatly refused. What kind of a mad engineer do you think I am to build something and not test it? Seriously.
Note to those tempted to vote to close for "actions of a single person": While the question is written in first person, the underlying question is generic to all time-machines.
