I think this was because the device could otherwise be made to let you know if information was successfully transferred. This is something I don't want to happen), the anchor point is turned off, and the universe splits into a new timeline. So if you die or the chip is destroyed, there's absolutely no way of knowing; you'll head off boldly into the future and die... and then that future just carries on - the device never gets the information in that timeline, and there's no way to signal to you before you start off that you will either die or the device is destroyed. It's only if you live to activate your return ticket is the data transfer realized, and you'll start living your life with one possible scenario in your head, but you'll be on a different timeline which branched off at that moment you first activated the anchor point. I'm hoping there's no flaw in that logic. Someone please correct me if I'm wrong.
Also, I'm thinking that the memories shouldn't be written in reverse chronological order, because this would present a huge continuity error to your brain - while you were watching time reverse, you would have no recollection of the period between the anchor point being set and the return, and this void would shrink to whichever moment you were currently watching until it caught up with the present. Then I thought - error checking? It accesses all of the memories/pathways created in reverse order to make sure it got everything right. The error checking takes much longer than the writing itself, and so this is what you see rather than the writing in forwards order (I'm imagining this as a blinding white light for a barely noticeable period of time).
What happens if you die, and the device is activated? Do you become brain-dead in the other timeline? That would suck. I suppose it could transfer back "null" and then... well then you'd be stuck in a recursive loop, provided everything happened the same way each time. At that point only another device could change things and save you by altering the timeline. Does that make sense, because I can see that providing an interesting plot twist.
I'd like to know how this sanity test works... or maybe I wouldn't.
And yeah, I don't have any time right now (I have a lab in <4 hours, which I will not be very awake for), but I will soon enough, and so I thought I'd start planning now..
In my vision of it, if you're dead, the device would not send back any information, unless a third party fools the BIC into thinking that it's in a brain, and so when it's activated in the past, it would basically tell the user "no data received" (suspense!)
Also... The model of time travel I'm considering is different from what you're describing... In my model, there is a single timeline, and it is a fundamental law of the universe that paradoxes don't arise. (Basically, http://en.wikipedia.org/wiki/Novikov_se ... _principle
) As a consequence of this, getting a "no data received" message is proof that the BIC is not operational in the future when the data would be sent. (This could either be a fixed point in time, or whenever the BIC sends back the data). The BIC idea could work with either model though, but this was the view my previous post was considering.
If you are going to consider multiple parallel timelines, then you can have the user receive an arbitrary memory, a sudden sense of fear, a flash of light... Anything that a BIC could cause a user to experience to indicate to the user that no tachyons were recieved. That this happens is not a guarantee that the person will die (and it might be a good idea to exemplify this early on), since receiving that memory splits the timeline. Similarly, receiving memories is not a guarantee that you will live that long (unless you successfully perform every action exactly like you "remember" it... but that would make for very boring time travel)
The BIC could also be programmed to transmit all stored memories on the death of its user, if and only if some condition is met... It can have the power of a modern computer, so there are a lot of possibilities. Just find something that fits into your plot with a minimal number of holes.
