General relativity is a non-quantum construct, so you cannot use it to make statements about quantum phenomena. It's like using Newtonian mechanics to make claims about relativity, it's not going to be fully right.The wave functions that create the geometry of space-time are also the same wave functions that create the difference in velocity between two inertial reference frames.
You haven't justified anything like that. Firstly, you still haven't been able to justify that changing frequency means creating a gravity field, that is not supported by any mainstream theory or experiment. Secondly, you haven't justify the formula you give. Frequency changes in relativity are not necessarily linear. For example the change in frequency of a photon moving in to or out of a gravity well is a non-linear function of height.So I ask, if I emit that linear frequency shift that I told you about, can I energize/activate those same wave-functions, along with the gravity (and/or acceleration field) that comes with it.
The problem is I understand too much, I actually understand what relativity has to say about photon frequency shifts and time dilation, such as that experienced by the GPS network. Compare that to you, who obviously haven't ever actually done any physics. Have you ever actually done any quantum mechanics, worked with wave functions?Doppler shift is caused by both gravity (acceleration) and difference in velocity. A generated frequency shift should recover a small fraction of both acceleration and velocity. Do you understand now?
You're clutching at straws. The behaviour of photons in general relativity is actually quite complicated, you have to compute null geodesics in the geometry. But since you obviously don't know any mathematical physics you can only grasp at linear equations, everything else is beyond you.The whole point of this exercise is to determine if this could lead to a opto-electronic acceleration field generators. The linear equation that I used is a starting point, a way to test proof of concept. If it works, then the linear frequency shift equation will inevitably have other frequency shift terms that make the field the field stronger. It will also have to include geometry in the designs as well.
Sorry, I have real physics to do.I'm sorry I have to go finish cleaning the apartment I'm moving out of. I have to move a heavy desk. Want to come along and help?
I doubt he read either article. I suspect he simply looked at the titles.

In your other thread you said "Looking that up on Wikipedia..." and basically admitted you don't know any of this stuff on a working level, you're just trying to make sense of pages on Wikipedia which you don't understand. You ignored all my comments about that, so clearly you have realised you don't have any real understanding but you're unwilling to admit it.

Mazulu believes that if he can make colored lights blink fast enough, he can trick the universe into accepting that the frequency is changing.
I understand too much physics to be taken in by the completely vapid and nonsense postings you have made. I understand too much physics to be blinded by buzzwords and technical terminology, because I work with that technical stuff everyday. You might sucker others in by throwing out lots of big words but it doesn't work with me.You understand too much about frequency shift?
There are occasional ideas about aether but none of them get even close to matching current ideas in terms of descriptive ability. Aether always seems to address one specific phenomenon and fails in regards to everything else. The crank community always try to resurrect it because they struggle to accept that light behaves in a way counter to their extremely ignorant intuition. Intuition is short for "I expect this new thing to behave like old things". It might have served humans well 50,000 years ago scratching a living out in the middle of Africa but it doesn't work well when you're exploring far flung corners of physics.When the physics community abandoned ALL aether mediums because the Michelson-Morley experiment disproved motion through a point-particle medium, the physics community made a mistake. There is an aether medium; it is extremely strange, but it exists as a naturally occurring phenomena.
Who says that? I'm a mathematical physicist in the research community and I don't know anyone who thinks that. Maths is an abstract logical construct independent of reality. Physicists attempt to make associations between structures within that artificial construct and phenomena observed in the universe but maths no more causes nature to have as it does than English causes reality to behave as it does.Some people think that math causes nature to behave the way it does. But the math is just an accounting system to keep track of how nature behaves when certain experiments are performed.
I seriously doubt you know all about radio, particularly the associated electromagnetic models.Yes I know all about FM radio. So why don't FM transmitters make wormholes? When light frequency shifts, it transitions from one reference frame to the next to the next. The very vibrations of that photon are interlaced with the medium of space-time.
You still don't get it, do you? You haven't provided a single nano-iota of justification for that formula or anything you're claiming in regards to it. You're just making stuff up without any evidence.The formula I gave you: f(t)= [df/dt]t + f_0, is the frequency shift that you have to generate, as quickly and accurately as you can, with as large a df/dt as you can, in order to create a frame shift, or frame slide, in front of your emitters.
You have no evidence for that.The better the performance of your frequency shift experiment, the stronger your gravity field will be.
Really? I find that extremely hard to believe given your complete dereliction of the scientific method in your posts. You haven't shown you understand anything about the need for evidence, derivations, justification, sound arguments, experiments etc. You don't even know the level of detail in the models required. Someone with a BSc in physics I'd expect to know a bit more details. I've taught 1st year physics undergrads more maths than you've displayed!I have a BS in physics, a BS in electronics, and I have taken some graduate level classes in electrical engineering, semiconductor physics.
You don't know at all.So how do I know that this experiment will induce a measurable gravity field? I don't know for sure without performing the experiment.
I'll file it under "BS" and I'm not referring to your supposed physics degree.Do with this information what you will.
Even a PhD doesn't make that certain. I could go on an enormous rant about the number of maths and physics PhDs I see during employment interviews which are useless at undergrad stuff which doesn't relate to their thesis area. It's a real problem and says something about the way science is taught (and that's not just about here in the UK, it includes examples from all over Europe and the US).A minor opinion; and speaking from experience...:
A Bachelors in Physics is respectable. It can get a person a nice job, but not at a University, not conducting research in Relativity or QM.
Definitely. I didn't really get my act together in terms of really being a motivated and competent mathematician until I was perhaps 2 years into my PhD! If I hadn't carried on in mathematical physics past Masters level I'd be a much less competent mathematician, even allowing for the obvious difference in how much information I'd gathered. I started to get competent when I stopped viewing the learning as "Someone puts the relevant information in front of me and I consume it" to "I want to find out about and understand this, so I'm going to go and look at it". Rather than reading other people's derivations or ideas once I got the basics from a book I try to see what I can do with it myself, before looking at other people's results. It might result in a reinvention of the wheel a few times but it helps so much in understanding. Just a shame it took that long for me to get into the right frame of mindA B.S. says one basic thing: "I am capable of learning."
It does not say, "I've learned what I need to know."
This is why many pursue their Masters and The PHD. To show, "I can learn more!" and get those jobs working with Relativity and QM so that they can finally, after years of education- buckle down to the task with appropriate tools to LEARN about physics.

The phase, from one frequency to the next, has to be as unbroken as possible. This experiment has never been done. If you think it has, then I recommend a smooth frequency shift from 400 to 800THz, every microsecond. There is no tunable laser in the world that can achieve this kind of performance. You will probably have to do it in frequency steps. The better the performance of your frequency shift experiment, the stronger your gravity field will be.

In physics the Einstein æther theory, also called æ-theory, is a controversial generally covariant generalization of general relativity which describes a spacetime endowed with both a metric and a unit timelike vector field named the æther. In particular such theory has a preferred reference frame and so is not Lorentz invariant.
In gravity theories with extended supersymmetry (extended supergravities), a graviphoton is normally a superpartner of the graviton that behaves like a photon, and is prone to couple with gravitational strength, as was appreciated in the late 1970s. Unlike the graviton, however, it may provide a repulsive (as well as an attractive) force, and thus, in some technical sense, a type of anti-gravity. Under special circumstances, then, in several natural models, often descending from five-dimensional theories mentioned, it may actually cancel the gravitational attraction in the static limit. Joël Scherk investigated semirealistic aspects of this phenomenon, thereby opening up an ongoing search for physical manifestations of the mechanism.
Speaking of people putting the work in front of you... the past year, the trouble I had is in getting proper guidance.Definitely. I didn't really get my act together in terms of really being a motivated and competent mathematician until I was perhaps 2 years into my PhD!

Or... as I lament above^ Claim excuses about how the proper coursework had a glitch and he must assume full credit for work he's seen from me so far (Even gave me 100% on one assignment I never handed in!)This is true.
Many lecturers today teach but they don't teach about the work in great detail. They might spew equations without explaining them in the proper rigor they require.
At the very least, it does provide some insight into why aether is a concern at all.The Einstein aether theory, was and is not Einstein's baby. It is a name given to an attempt to resurrect the aether with an air of credibility.
There are and continue to be explorations of an ether like relationship between space and matter. The credible attempts are likely the result of remaining inconsistencies in GR and QM and a fundamental tendency to want to find some way to explain matter energy-relationships in a manner consistent with classical experience.
There are some better references to ether interpretations of both GR and Newtonian gravity than WiKi. However, this is getting away from the subject currently under discussion.
I would like to see more research into the question of whether or not wave-functions are real.
Penrose speculates that the transition between macroscopic and quantum states begins at the scale of dust particles (the mass of which is close to a planck mass). Dust particles could exist in more than one location for as long as one second, a time that is easily measurable with standard equipment.
We physicists believe, for example, that there is really a multiverse that exists even inside our living room. We are waves, vibrating waves given by the wave-function, and these waves vibrate and then split apart with time.
Steve Weinberg, winner of the Nobel Prize, compares it to the following. Think of radio. If you’re inside your living room listening to BBC radio, that radio is tuned to one frequency. But in your living room there are all frequencies - radio Cuba, radio Moscow, the Top 40 rock stations. All these radio frequencies are vibrating inside your living room, but your radio is only tuned to one frequency.
Now, in other words when two universes are in phase, they are coherent and you can move back and forth. But as time starts to evolve, these two universes decouple. They start to vibrate at different frequencies. They can no longer interfere with each other. So why is it that your radio cannot listen to Radio Moscow? Why isn’t it possible for your radio to listen to all frequencies? Because your radio is decohered. It is no longer vibrating in unison with these other frequencies.
And the same thing in quantum physics. We consist of atoms. Our atoms vibrate, but they no longer vibrate in unison with these other universes. We have decoupled from them, we have decohered from them. So in other words, deja vu is probably simply a fragment of our brain eliciting memories and fragments of previous situations. However, in quantum physics, there really are in some sense parallel universes surrounding us, the problem is, we can’t enter them because we have decohered from them. We’re no longer vibrating in unison with them. Sorry about that.
Reading through the referenced posts will give you a very basic introduction to quantum mechanics - algebra is involved, but no calculus - by which you may nonetheless gain an understanding sufficient to see, and not just be told, that the modern case for many-worlds has become overwhelming. Not just plausible, not just strong, but overwhelming. Single-world versions of quantum mechanics just don't work, and all the legendary confusingness and mysteriousness of quantum mechanics stems from this essential fact.
What we call the aether is possibly related to the wave-function of the universe, in that finite branching natural number occurrences emerge from a continuum of real number possibilities. Once a theory can establish a causal connection between the parallel worlds, the theory should in principle, be testable.
Hypothetically speaking, atoms exist in multiple parallels simultaneously. Indeed, the double slit experiment even displays wave particle duality for some types of macromolecules.
The larger a particle, the smaller its DeBroglie wavelength. So bigger macroscopic beings perceive themselves as existing in one universe, while individual micro-particles can exists in multiple realities simultaneously.
Objects as large as dust-specks can briefly display wave particle duality...

While Penrose does not advocate the MWI[many worlds interpretation], if a dustpeck can disappear for up to a second it could be jumping to alternate realities during those brief moments, if, MWI is true.

Khan,
The many worlds interpretation has big problem. First, every time the universe splits in two, you have two universes, each with an energy content of "a big bang". Each of these universe exerts gravity. You would have two earths exerting gravity (or millions of earths exerting gravity). The model violates conservation of energy in absurd ways.
Stephen Hawking says:
There are something like ten million million million million million million million million million million million million million million (1 with eighty zeroes after it) particles in the region of the universe that we can observe. Where did they all come from? The answer is that, in quantum theory, particles can be created out of energy in the form of particle/antiparticle parts. But that just raises the question of where the energy came from. The answer is that the total energy of the universe is exactly zero. The matter in the universe is made out of positive energy. However, the matter is all attracting itself by gravity. Two pieces of matter that are close to each other have less energy than the same two pieces a long way apart, because you have to expend energy to separate them against the gravitational force that is pulling them together. Thus in a sense, the gravitational field has negative energy. In the case of a universe that is approximately uniform in space, one can show that this negative gravitational energy exactly cancels the positive energy represented by the matter. So the total energy of the universe is zero.
Now twice zero is also zero. Thus the universe can double the amount of positive matter energy and also double the negative gravitational energy without violation of the conservation of energy.
"It is said that there's no such thing as a free lunch. But the universe is the ultimate free lunch."
Nice try.Branching universes do not violate conservation of energy if the total energy of the universe is zero.
The only place dust ever disappears to is ... my vacuum cleaner.While Penrose does not advocate the MWI[many worlds interpretation], if a dustpeck can disappear for up to a second it could be jumping to alternate realities during those brief moments, if, MWI is true.
I'm thinking of gravitational redshift. http://en.wikipedia.org/wiki/Gravitational_redshiftI don't fully understand what you mean by there being a connection between frequency shift and gravity but there is the interesting idea of "graviphotons", yes.
http://en.wikipedia.org/wiki/Graviphoton
But nobody has ever tried to generate a frequency shift to see if it can induce an acceleration field, a change in velocity of an inertial frame or increase the distance between two objects.
For the strong gravitational field of a circulating cylinder of light, I have found new exact solutions of the Einstein field equations for the exterior and interior gravitational fields of the light cylinder. The exterior gravitational field is shown to contain closed timelike lines. The presence of closed timelike lines indicates the possibility of time travel into the past. This creates the foundation for a time machine based on a circulating cylinder of light.
Later, Mallett abandoned the idea of using slowed light to reduce the energy, writing that, "For a time, I considered the possibility that slowing down light might increase the gravitational frame dragging effect of the ring laser ... Slow light, however, turned out not to be helpful for my research."
