So, when I first read about this, I was like, okay, so why is this valuable at all? I'm like a severe layman, so my science talk crap may be wrong, but...
Neutrinos have Small but Non-Zero mass, right? The key word here being small.
So you really don't have any ability to generate thrust with them. We are still restricted to the speed of light.
Then I thought about it and the wave collapse function, and any practical use. It is worthless to send data, but it can provide data compression or definition to data based on "pulses" in the combination of the light streams. You still have light speed communication since the data requires the contact of the lightstreams, but you can then execute Morris code sort of data transmission, providing possibly the ability to ride additional data down the "pipe" or send a different kind of data compression on that basis. Pretty worthless, but there might be some kind of application in a informational sort of way for data compression. I don't think it'll ever be worthwhile to do so, but I won't rule it out.
This put me on the mind of communication though. Neutrinos come in multiple flavors, which this experiment was supposed to do a little discovery about.
Assuming superluminal neutrino speed is possible, and that there is a way to determine what flavor of nutrino we have arriving at a long distance, and that it is expected of any civilized race who survives the development of the Nuclear Age to know this information, what does it mean for extraterrestrial communication?
We may not be seeing any extraterrestrial intelligent communication because perhaps Radio Waves isn't the way it's done!
So yea, there's my crackpot theory out of this. It'll be proven wrong soon, but it was fun to come up with it
