I think I understand the problem you...Hello Ziggy,<br /><br />I think I understand the problem you have with Unruh radiation. Allow me to take another try at explaining it to you. You said this:<br /><br /><i>On the other hand, in quantum mechanics, in case of a virtual pair made of TWO particles, in principle, it is possible that one of them could be invisible behind YOUR horizon, and the other one visible. </i><br /><br />So far, so good. You appear to understand the idea. Continuing on you said this:<br /><br /><i>Now, you say, that from your relativistic point of view it is true that, effectively, the invisible particle does not exist (for you). True. </i><br /><br />Very good. Effectively is the most important word here, please remember that. Continuing on:<br /><br /><i>Therefore your invisible particle of the pair is still visible to the other particle, and that is the reason that your visible particle is not free to go alone, because the connection between the pair does not become broken merely because you do not see one of them. Therefore the pair will annihilate, and there will never be any radiation. </i><br /><br />This is where you are having your difficulty. You aren't applying relativity here deeply enough.<br /><br />From a stationary observer, a virtual particle pair will arrive, annihilate each other, and then disappear. That is what happens, and it appears you understand that as well.<br /><br />Now - let's assume an accelerating observer and a Rindler horizon between the two virtual particles. The stationary observer will still see two particles with opposite attributes wink into and then out of existence. <br /><br />But the accelerating observer with a Rindler horizon won't see the same thing. The accelerating observer will only see one of them. You said as much above, your second quote confirms that.<br /><br />Now here is the important bit. Again, relativity. <br /><br />Remember my example with the star? The observer who leaves just before the explosion will live in a universe with the star always present?<br /><br />From the point of view of the observer leaving the scene at c, that is reality. The star always exists. A stationary observer has a different reality, the star explodes.<br /><br />Likewise, an accelerating observer will only see one particle of the virtual pair. A stationary observer will see two matched opposite particles wink into and out of existence. An accelerating observer will see only one, but that <i>will be their reality</i>. And since they only see one, there isn't an antiparticle <i>in their universe</i> and it won't annihilate. Because in their universe it doesn't have an antiparticle to annihilate it. It will persist just like a star just before supernova will persist if you run away at c. So since it remains in their reality, they will perceive it as radiation in a manner similar to Hawking radiation. And that is called Unruh radiation.<br /><br />Yes, it is terrible.<br /><br />It is horrible to think that acceleration is related to your personal reality. I hate knowing that when I am at the movies and I clap my hands, since they are in different accelerating frames they are in different universes. It is terrible to think about. It can drive you to drink. But it is absolutely true.<br /><br />Keep pushing onward, you are close to understanding this. Relax and give yourself permission to understand that relativity means there isn't any fixed reality. It's not space, and it's not time, it's spacetime and your movement through it determines your entire universe.

There may be an explanation using the SchrÃ¶dinger wave function though, since that exists over all known space at the same time and must also have nodal points (zero probability) at the horizons since there is "nothing" beyond them. The explanation seems to remain much the same, and since moving the edges of the probability density would also need to move the middle of it (where we actually see the particle), then it would give a reason why the particle has inertia. This reduces the scope of the SchrÃ¶dinger wave from infinite to only occupying all known space, but that's maybe a small price to pay and also makes somewhat more sense anyway. If the wave function spread into unknown space then there would be a probability that the particle jumped to unknown space. The requirement that the probability is exactly zero at the horizons will limit the spectrum of the waves that can be used to build the wavefunction. The maths for this is beyond me, though, so I'll leave it to others to think on.Simon Derricutthttps://www.blogger.com/profile/15137826634256652580noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-36600308207754110532018-01-19T19:37:13.478-08:002018-01-19T19:37:13.478-08:00Let's calculate this :

Inter...<i> joesixpack said on 15 January 2018 at 19:01<br />Interesting article, resource and alternative to Wikipedia (for students such as myself): http://www.scholarpedia.org/article/Unruh_effect<br />No mention of our friend Smolyaninov.</i> <br /> <br /> <br />Every physicist, who aspire to be unbiased and objective about his own pet-hypothesis, should try to put a comparable effort into verification, as well as into falsification. <br /> <br />My complaint about some people here is that they seem not to be self-critical enough, and tend to conveniently ignore most arguments in favor of Unruh radiation falsification. <br /><br />Well, I have just realized that I may be guilty of the same, i.e. favoring falsification of Unruh radiation. <br /> <br />Since Joe Sixpack suggested the above link, let me quote: <br /> <i> <br />" The Unruh effect is a surprising prediction of quantum field theory: From the point of view of an accelerating observer or detector, empty space contains a gas of particles at a temperature proportional to the acceleration. <b>Direct experimental confirmation is difficult because the linear acceleration needed to reach a temperature 1'K is of order 10 to the power of 17 km/s2,</b> but it is <b>believed</b> that an analog under centripetal acceleration is observed in the spin polarization of electrons in circular accelerators. Furthermore, the effect is necessary for consistency of the respective descriptions of observed phenomena, such as particle decay, in inertial and in accelerated reference frames; in this sense the Unruh effect does not require any verification beyond that of (relativistic-free) quantum field theory itself. The Unruh theory has had a major influence on our understanding of the proper relationship between mathematical formalism and (potentially) observable physics in the presence of gravitational fields, especially those near black holes." </i> <br /> <br /> <br />Well, let's start from the bad news that any <b>direct experimental confirmation</b> will be next to impossible, because the linear <b>acceleration</b> needed to reach a temperature of 1'K would be far out of-the-charts at approx. <b>10,000 Trillion kilo</b> meters per second square. <br /> <br />The way I see it, the problem is as follows: I want to push my family mini van, and to get it rolling I need to accelerate it just a wee bit, so I try to push it, but it is full of shopping and heavy, and before it even budges, I can feel its inertia. Now, it has started rolling! So, let's try to calculate the actual value of the acceleration and the corresponding value of net Unruh radiation pressure difference on my family mini van, because from the point of view of my <b>accelerating</b> mini van, empty space contains a gas of particles at a temperature proportional to the acceleration. <br /> <br />Let's imagine that the temperature in front of my mini van is 1'K lower than in the back of it. There is a net pressure difference that should push my car forward. I imagine that in the winter, if I light a bonfire behind my car and start blowing on it, it will accelerate the car forward, and if we reach the temperature difference of just 1'K, then its acceleration will be as calculated above... ?? <br /><br />OK, this was just a joke, of course, but <b>please correct me if I am wrong:</b> We need an un-imaginable acceleration in order to produce a mere 1'K, so in case of the near-zero acceleration of my mini van, do we produce enough net difference to justify the inertia that I feel before my car budges? <br /> <br /> <br /><b>Another interesting issue is this : </b><br /><br /><i>" Unruh effect does not require any verification beyond that of (relativistic-free) quantum field theory itself.</i> <br />Ziggyhttps://www.blogger.com/profile/12215297051145082904noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-79538684979789279612018-01-19T16:24:01.971-08:002018-01-19T16:24:01.971-08:00Ziggy,

This is not as mad as it sounds, given the EPR paradox." It might be helpful to give some historical comparisons.<br /><br />Soon after Maxwell created his equations of electromagnetism, it was realised that they had two solutions, the retarded solution (which corresponded to electromagnetic waves as we know them) and the advanced solution (which corresponded to electromagnetic waves travelling backwards in time). Most people thought that the advanced solution did not have a physical significance (this is what I was taught in the 1960s). There was a notable disagreement back in the first decade of the 20th century between Einstein and Ritz (http://www.datasync.com/~rsf1/rtzein.htm) where Einstein argued that the advanced solution was equally as real as the retarded solution.<br /><br />In the mid-1940s Feynman and Wheeler created a time-symmetric absorber theory of Quantum Mechanics. While this was unsuccessful, out of it came the transactional interpretation of QM (https://en.wikipedia.org/wiki/Transactional_interpretation) that was developed by John G Cramer in 1986 and uses both advanced and retarded waves. As Wikipedia describes it: 'In TIQM, the source emits a usual (retarded) wave forward in time, but it also emits an advanced wave backward in time; furthermore, the receiver, who is later in time, also emits an advanced wave backward in time and a retarded wave forward in time. A quantum event occurs when a "handshake" exchange of advanced and retarded waves triggers the formation of a transaction in which energy, momentum, angular momentum, etc. are transferred.'Laurence Coxhttps://www.blogger.com/profile/12022978799028708943noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-46415431693177782192018-01-19T04:05:07.788-08:002018-01-19T04:05:07.788-08:00Well said "Unknown".

You are barking up the wrong tree there and I agree that Smolyaninov's paper/results require more confirmation and repeatability. We indeed should question the validity of Unruh radiation results, black holes and the LIGO data - and yes even the JPL work on the EM Drive (but no one has disproven it yet). <br /><br />I think Mike has 20+ papers now showing empirical confirmation of QI. If he has the explanation wrong, that can change later. (We still, after all, don't know why C is except in special circumstances, invariant). The sum of the empirical statistical modeling rejects a hypothesis of falsification for QI.<br /><br />The challenge now would be for you to accept the empirical results and explain what the mechanism is of the EM Drive that converts "lost" EM radiation into Unruh radiation. joesixpackhttps://www.blogger.com/profile/08912279232742819732noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-56686567596167113672018-01-19T00:05:23.515-08:002018-01-19T00:05:23.515-08:00David Lang writes:

Especially if they can explain and let us optimize an EMdrive.<br /><br />Why it works is FAR less important than the fact that it does work, and if QI let's us predict the effect from the design, the rest doesn't matter much.Unknownhttps://www.blogger.com/profile/12084309137541367977noreply@blogger.com
