FTL Device Diagram:
Wave Mechanics: Quantum Physics: Quantum Tunneling in Conciousness: FTL Networking Concepts: |
Recently, it has been demonstrated that a signal can be modulated and sent at up to 30 times the speed of light thru the use of quantum tunneling. See http://www.compu-web.com/ftl.html for more details on the specifics.
By using this means, arbitrary negative time displacements can be created. It's indisputable that the photon is being detected before a photon that travels thru ordinary vacuum. If you believe that a single change of state can contain information (which every network engineer would agree with), then you MUST accept that this can be used to send a message into the past. The reasons have to do with relativity theory and can easily be shown by drawing space/time diagrams. I won't discuss those here but direct you to some of the links on the left to prove this much for yourself. There are many ways to address time travel paradoxes. One is to adopt the "many worlds" interpretation. There is no reason to discount this interpretation. Consider that two points that are outside each others light cones. As long as they remain outside their respective light cones, they are in separate universes for all intents and purposes. The set of points that are mutually outside one another's light cones is infinite (and increasing because of the cosmological constant which is used to explain why the expansion of the universe is accelerating. So it is logical that there are an infinite number of universes. It is NOT logical to assume that the "splitting" of universes that occurs when the quantum wave collapses is a UNIVERSAL (or non-local) phenomenon. In other words, I'm not suggesting that all atoms in the universe are duplicated just because a single particle is observed. If you consider that such splitting only occurs "locally" and spreads at no greater than the speed of light, then order/logic is restored. In any event, it's one way to explain what this device really is. It may not really be a time machine. It may simply be a way to send a signal to another adjacent universe. Exactly how far away that universe is from ours WRT others in the multiverse is another question entirely... Since quantum tunneling doesn't involve actual travel faster than light (instead, the photons arrive earlier than they should), this doesn't directly violate relativity. |

"WAIT!" you say. "Yes, the measurement of the evanescent wave thru the tunnel has been shown to have speeds greater than light. But the SIGNAL velocity is still lower than light speed." MY REPLY: "Good question. My response is that it is already accepted that the phase and group velocities of a wave are the same (De Brogle wave applet to the left). It is therefore necessary only to demonstrate that the arrival of the evanescent wave at greater than light speeds can send information. The way I propose to do this is to measure the arival of the evanescent wave and use the following scheme used in everyday networking:
Would that not count as sending information at greater than light speeds? The arrival of the evanescent wave occurs multiple wavelengths ahead of a wave sent at the speed of light. The experiment showing Nimtz' work showing FTL speeds is well documented on http://www.compu-web.com/ftl.htm and claims speeds of over 30 times 'c'! Read his paper (published in the URL itself) and see for yourself. Guenter Nimtz has shown he can send a signal over a .1142m gap in 81 picoseconds which is 4.7c! I should note that Nimtz himself states that this can not be exploited for FTL signaling. Perhaps so but I can not determine why not. If you have any comments, drop me a line on [email protected]. For more background on what tunneling is, I'd recommend:
As soon as I saw Nimtz work, it occurred to me that sending a signal back more than 200 picoseconds had nothing to do with building a longer quantum barrier which travels 'n ' times the speed of light (where 'n' >1) that has a greater negative time displacement. Instead, hook multiple quantum tunnels up in a loop (as shown in the URL) and send a wave thru the barrier(s) billions of times per second. Each pass thru a quantum tunnel has a very small negative time displacement WRT the lab frame. This allows for arbitrary negative time displacement since the number of passes thru the ring can be controlled. Interested? Then please check out my diagram above complete with Lorentz equations showing what the negative time displacement of a wave that travels at 4.7 times light thru the barriers. Keep in mind that I'm assuming that the quantum tunnel speed shown by Nimtz is correct. I'm just trying to engineer a working FTL radio from this that has reverse-causality possiblities. HOW TO BUILD A REAL TIME MACHINE WITH FTL DEVICES: Lets say you can send a signal at 5x the speed of light to someone 100meters away. Plug this into the Lorentz time-dilation equations and you get a negative time displacement of only .00000033 seconds. BIG DEAL! Nothing you could take advantage to buy some stock. :-) One thing to keep in mind here is this: Any FTL device will not look special from YOUR point of view. You won't see the particle travel back in time. You'll see it move forward. But from the PHOTON'S point of view, it sees events in reverse order from you. All you have to do is "query" the photon later and you're seeing events from a future. The GIF file on this site show how you'd have to arrange the quantum barriers to a very fast switch to make a sort of FTL network. By incrementing the packet each time it goes over the FTL link, you can determine how "old" it is and get arbritray negative delta-t's because the signal can theroetically go around the loop hundreds of millions/billions of times per second. Now instead of very small negative delta t's, you have something much larger, no? I've included the negative delta-t calculations using the Lorentz equations from the POV of the observer and it looks appears that the time dilation effect is a minus .18 sec per 1 second of observer time is possible using a loop of FTL devices. Also, the switch would have to be very fast (possibly 122 million packets per second). But by making the number of barriers very very large, you can ensure that the RATE at which the waves approach the switch in the diagram is reduced to something more "normal/possible". What are your thoughts/flames/comments? I know, I know... This is impossible. But let's place that behind us, roll up our sleeves, and build a working FTL temporal device! -Chris Elfers [email protected] |
