What do you mean by "it is not possible to erase the information well enough to sense this without coincidence counting"? You are right about the diagram, also. Cheers.

I have a related question, I think. I have been reading about the Scully-Druhl experiments where the photons are directed to down-converters, which create a "signal" photon and an "idle" photon, and in which it appears that the idle-photon gives information about which path the signal photon...

I see what you mean. But let's assume it is a simple set of states that I have complete knowledge of, and I can predict a future state with complete accuracy as I have managed to discover all the laws of physics. This then removes the impediments of unknown elements as far as I can see...

This is probably the stupidest question I have ever asked, but it is bugging me and I am looking for an illuminating answer - not one that simply tells me I have the wrong idea, but one that explains in what way I have the wrong idea. I can, based upon some knowledge of initial conditions and...

Actually, one more thing, is it coincidental that the information creation and destruction even out, or is there an actual relationship there?

Thank you Chronon, I think I understand a bit more because of your post. To fully try and grasp it, I am going to try and rephrase the question as best I can (or ask a new but related question, rather). If we take a sequence in time in which it is impossible to determine the next state of a...

Thank you for your reply. I was specifically curious about time reversal and objective randomness, which I understand is a phenomenon of quantum physics and not classical physics. I did not really know that other systems were not time-invariant: I thought that they just appeared that way on...

I am not a physics student - I am a science fiction writer. But an idea is puzzling me, and I will attempt to convey it. However, I apologise if my terminology or an incorrect understanding of things makes my question unclear. Firstly, I am under the impression that the laws of physics do...
