Returning to fun and magic

Reading Classic Feynman, I'm remembering why he was my role model growing up, and I see where much of my outlook on life comes from. A lot of stuff about me comes as a direct result of some of his ideologies. Amazingly, I forgot one of the most important lessons: enjoy what I do. I've been enjoying school through escapism, like video games and stuff, but the real joy is in playing with the physics. He thought he got burnt out, too. Feynman realised later that physics was work because he wasn't playing with it.

Shortly after reading that, I sat down and read the last chapter of the QM textbook (I was on my way to the appendix when it caught my eye). And I knew I was reading the stuff for fun, comparing it to the article "Is the Moon Really There?". While reading, a bunch of stuff suddenly clicked into place, and it was then I realised why I love physics. This is what I wrote down then so I could pick up the train of thought later:


While reading my Intro to QM book (pg 427), I got to thinking:
What if the whole waveform collapse is a superluminal transmission of information? Feynman had a facinating outlook on this stuff, and his idea was that the path that either photon took when going through the double slit situation in Young's experiment was that it passed through all possible paths. These paths, should they all be summed up as the universe is so excellent at calculating - these paths all add up to the one path taken by the photon. If some bit of information is missing in how the universe decides the path, ie. the photon could've gone through either slit, then the universe loses that information in the sum, and darn if the photon doesn't act as though it does go through both slits at once. Sum-over-histories it's been dubbed.

So here's one of the problems: where do the paths begin and end? Well, the photon can't know it's destination before it gets there, right? Speed limit of the cosmos and all that. Yet experiments show there is a spooky effect in place, because the silly thing does seem to have a very good idea of what's going on. The idea here is the waveform collapses across all the universe instantaneously when the photon smacks into the barrier at the end of the experiment. I find this facinating, but gimpy - we still have no idea what the quantum waveform is and how/why it collapses. And we still don't know how the blasted photon seems to know what the outside world is like. Remember, the universe is nonlocal.

Here's my idea: information can go faster than the speed of light, and all those temporal paradoxes are fine. Here's why: the universe has to sum the data up somehow, so why not simply make time a factor in the sum; as in, the photon takes a path, but when the photon hits something, the effect propagates backward in time as well - the transmission of that being that history always writes itself to what actually happened (see Brian Greene's Fabric of the Cosmos and it's explaination of a modified Young's experiment - you'll see that adding information or taking away information about the experiment has an interesting effect on how data must be viewed and exist). Now, it's not like the time reversed effect actually can affect anything at all: merely, the effect of the event is felt on everything in a propagating wave backwards in time (this makes sense since [a] there is a general symetry in time in physics (true since I am not talking about large aggregates of particles, so the 2nd law of thermo won't really apply here) and [b] nonlocality would presume that the effect could move very fast, since the tangling coherance in the future would need to be resolved backwards in time - kinda of a dt/dt problem, cancels in the end, but exists for an interesting moment in the equations).

So the effect of the collision bounces backwards in time, since the universe is never wrong about its history. As the effect is thrown back, it will come across itself at an earlier time. The waveform of the future self will interfere with its olderself, and since, on some level, there is a time independant portion of the waveform, an instant by instant interferance will occur. This will change the particle's specific waveform constantly (since time itself is integrating into the past, the changes will be immesurably fast, thus perhaps part of the uncertainty will arise from that).

As a result, temporal paradoxes cannot occur since the universe is summing up reality constantly, and since the past has already occured, it cannot not happen. But we can change the way it is interpreted to a certain extent - obfuscating the past in a way (like the destruction of the chosen slit data in Greene's experiment mentioned earlier). The constant interference across time means data is constantly under reinterpretation. Note that the waveform is not sending data forwards into the future: there is no pinging of data, mere;y that the future version of a waveform is interfereing with all other waveforms that each propagate forward and backwards in time. Thus, given enough time, the photon's highly unlikely path to alpha centauri and back will be taken into account in the double slit experiment, and the path will have been nearly cancelled out when it intersects with it's opposite trajectory. Thus only reasonable things actually occur. Irrational stuff doesn't happen since it's pushed under by the statistical weight of infinite summing over time.

This is, of course, just something that occured to me, and I will run with it for a while. It's an interpretation that I have not really come across before, and regardless of it's truth, is a useful way of reconciling a few odd things. I would like to see how it actually fits with current theory.

Maybe this'll get me to study harder, cuz now I'm playing with physics, and it's fun. I don't feel burnt out at all (but I didn't spell check, sorry :)
And yeah, a Foof will be waiting for me when I get back :P

Oh yeah, and my computer is dying again. All data was backed up today, fortunately! Almost lost all my Chip's Challenge work from the last few days...
