Light ties itself in knots - spontaneously
The Register ^ | 29th October 2012 23:59 GMT | Richard Chirgwin

It’s not only possible to get light to tie itself in knots: given the right conditions, it will do so spontaneously, according to a paper published last week in Nature.

El Reg has no possible hope of fully understanding this paper (published in full, an emerging trend we welcome), but one really interesting idea is right there in the abstract:

“We anticipate similar spontaneous knot topology to be a universal feature of waves whose phase front is twisted and nonlinearly modulated, including superfluids and trapped matter waves.” [Emphasis added]

In other words, this research has the potential to be replicated not only to create “knotted waves” of light, but of waves in more tangible stuff.

“Knotted light” is already feature of research into things like optical tweezers and quantum computing. However, according to ANU researcher Dr Anton Desyatnikov, previous demonstrations have been painstakingly hand-made using carefully-engineered lasers.

“[W]hat we’ve been working on are models in which the knots spontaneously form on their own”, he said. “Apart from their curiosity value, what’s really interesting and useful about these knots of darkness is that they show you what the power flow is doing.”

“Our models suggest that you have to get the key parameters of the light in a certain range before you can easily tie the light in knots but once you do, the knots are virtually guaranteed … we can’t predict exactly where they will form. Just that under these specific circumstances the optical vortices will spontaneously nucleate and tie themselves into little knots.” ®

Very good ~ this is probably part of the secret of how double-helix water molecules formed in new stars pick up other elements to become DNA!

Those knotted hunks of star light spilling through those molecules would create energy flow patterns that would selectively filter out specific atoms adrift in the stream of water for inclusion in the matrix of the double-helix molecular forms.

So, thanks ~

Oh yeah.

We did NOT cover this in culinary school.

Lissajous curves, yes. But this doesn't seem bounded by a rectangle. And the whole knotted light thing... Over my pay-grade.

I read the article until it took a non-linear track and tied itself into knots and my eyes defocused.

God’s power is infinite...I doubt we ever fully figure out how the universe if put together fully...think about it...we have not yet found the smallest particle nor do we know with certainty the whole of our reality...all physical is finite I am sure, but the conceptual is not...there is your proof for God...

Could be ~ but did you read the paper? Used to spend evenings into the wee hours talking about this stuff with a couple of topology majors.

Bothers me somebody could finally put this down on paper so it is so clear and obvious ~ even intuitively obvious ~ it explains the self-assembly method for light to create energy gradients on a small scale that could literally turn an atom ~ maybe even just an electron, or a proton ~

This is some break through stuff.

And here, for our enjoyment, is a mathematical explanation of what the start of the universe (the manifestation of first point/moment, then the further expressions as temporal influence grabbed hold), generated as the fundamental characteristics of what God used to build our where/when. [Is the manifestation of life merely a phase shift, inevitable fromt he fundamental construction of our where/when? ... IMHO, only if we assign another dimension designation to 'life force' which could manifest connection with the forming where/whens. Such 'another' dimension could have been called into existence without dependence upon dimension space and dimension time, but intertwine with them due to some phase shift in continua generated from first principles in His Creative work. It is akin to the 'membrane interaction' posited by some string theorists, I think. On our '4D membrane' events cannot occur without time and things cannot exist without space, but there may be complex manifestations of spatio-temporal continua as membranes, which do not menifest int he same fashion as our reality in 'three of space and one of time'. Would a designation of S3T1 be a useful expression, so that S2T2 would also be a useful expression?]

I would suggest converting the superscript numbers to subscripts to avoid confusion. Traditionally, superscripts are used to denote powers, whereas subscripts denote multiples. Accordingly, your proposal for this created universe would be "S3T1". (Which, of course, tracks with the same convention in chemistry: "H2O"...)

For my own purposes, I sometimes "expand" your expression to "L,W,H, T" or "X,Y,Z, T"...

But I am looking for a way to designate 'variable expressions' of dimension Time, to express dimension Space as point, linear, planar, volume (or length width height, your L,W,H, cited as it manifests rather than as pure geometric terms).

Would you agree that a photon is composed of a smidgeon of space, a snatch of time, and energy? ... I would express that as point (spatial component of a thing), a moment (temporal component of a thing) and energy.

Due to the nature of the photon which is limited to a linear/present continuum, the moving thing manifests a wave nature in the volume(spatial)/future(temporal) Universe, kind of like a photon casts a 'shadow' upon the '4D universe' because it is existing in motion in one of the expression states of dimension space and or dimension time.

Apply that notion of 'casting a shadow' upon our '4D' to the effect of 'something' casting its shadow manifesting 'gravity' in our '4D'. What might be the 'thing' causing this shadow? ... Perhaps, since all things have temporal component to it at the most fundamental level, perhaps it is the 'massing/collection' of temporal 'grains' (or moments in my cosmology) which generates a temporal effect we interpret as mass curving spacetime.

I'm glad to see this, dear brother in Christ. I was just about to write the same thing, at least WRT superscript numbers. Where they are used in mathematics, they are generally understood to signify a raising of a power.

MHGinTN's highly interesting question:

Would a designation of S3T1 be a useful expression, so that S2T2 would also be a useful expression?

Question for my dear brother in Christ MHG: Did you intend to say "S2T2" here, "or S3T2?" I thought perhaps the former may be a typo. The latter to me suggests a "volumetric" extension of "ordinary" spacetime — i.e., S3T1, expanding to S3T2.

At the same time, TXinMA seems "also" to be correct: Subscripts denote quantity — in this case, 3 of space, and 1 (0r 2!) of time.

Thank you so very much, dear MHG, for your fascinating idea!

Yes, a typo. The expression S3T1 would be the realm of our sensory measuring (the assimilator/mind/live being being in a planar present orientation), with the single variable expression of dimension Time as 'linear' or past. T2 would be an expression of planar Time, or present. ['Present' occurances are inaccessible to us in our conscious state which is oriented to S3T1 for rational understanding of the universe of our sensory mechanism, because we must 'receive' data/information and then process the information to generate a mental or 'soul' mechanism 'projection' of reality in the present based upon what has already happened. I take the soul to be mind, emotion, and will. The spirit is not the soul but shrouded 'within' the soul.]

It is akin to the 'membrane interaction' posited by some string theorists, I think.

Indeed, following quantum field theory a phase shift would be the most likely consequence of God's creative speaking, "let there be," to or in space/time.

Concerning the sidebar on subscript/superscript designations - I'd add that Wesson shorthands his theory like this: "5D2T" meaning five dimensions, two of which are time dimensions - spatial being the default D.

In that shorthand 0D would be the only point (the Big Bang singularity), 1D a line, 2D a plane, 3D a cube, 4D a tesseract, etc. However, when we shorthand 4D concerning space/time, the 1T is assumed (4D1T). LOLOL!

So I guess the bottom line is whether the shorthand is communicative.

BUT, the naming of 'it' means it must have space to exist, and the command 'to be' indicates it must have time, to be an event in existence.

Years ago, I started trying to fathom how it all began, the order of 'unfolding'. That's why I've settled upon the notion of continua I express as where/when continua. Even the soul and spirit exist in a continua of some expression of space and time.

The 'first' continuum was point/moment. During the inflationary phase, the universe went from point/moment to linear/moment, linear/past, then linear/present, planar/present, etc. and eventually volume/future. But the expressions 'present' and 'future' I do not think of the same way traditional 'one variable of time' notions assert.

I best stop before the ridicule rains down, as it has in the past when I sought to share this 'different' cosmology.

Thank you so much for sharing your insights, dear MHGinTN!

I gather we agree that the Big Bang theory calls for a singularity which is a mathematical point. And from there dimensions are created as it expands, e.g. space/time continuum. Or to put it another way, space/time does not pre-exist, it is created as the universe expands.

Observations of the Cosmic Microwave Background radiation shows that photons (physical light) came into existence about 300,000 years after the Big Bang based on our present space/time coordinates. Interestingly, the CMB records the sound waves at the moment physical light came into existence.

That, of course, always reminds of "Let there be light" or as you put mentioned earlier, "Light be."

But such measurements only apply to the observable universe.

For instance, by definition science cannot say that massless particles which have no direct or indirect effect do not exist, i.e. they cannot be observed. Or that fields which have no direct or indirect effect do not exist. Or that other types of dimensions which have no direct or indirect effect do not exist.

Physical cosmologists rarely speculate about non-observables.

Wesson's point that physical death is merely a phase shift ("in" 5D2T space/time) is particularly fascinating to me. I don't know if such a phase shift in 5D2T would be observable but in any case, that there may also be unobservable dimensions/fields bring various Scriptural events to the table, as you have noted.

The soul/spirit (whether associated with a physical body or not) is still a "thing" or "being" and experiences "events" which means it is "in" the continuum though it may not be measurable by a scientific observer in 4D. To put it another way, in the absence of space, things cannot exist. In the absence of time, events cannot occur.

I suspect some scientific observers prefer to associate everything mind related to a physical brain simply because they cannot physically measure the mind, soul or spirit. Thus they call the mind an epiphenomenon, a secondary phenomenon which cannot cause anything to happen.

Lurkers interested in this sidebar might want to look over our discussion on this thread.

So does this happy little notion of the physical scientists mean that "brains" cause wars, commit murders, rape, pillage, "ethnic cleansings," etc.?

To say that the "brain" is really what does everything really lets me off the hook for moral responsibility for anything I might willy-nilly choose to do — I can blame anything and everything I do on my "brain."

Good grief!!! I guess this would mean that I cannot let my "brain" wander outside my own house, lest it cause harm to others!!!

I honestly think that people who actually believe such things are just totally NUTZ. The world does not entirely reduce to "measurements." Indeed, probably the most significant part of it is "immeasurable" in principle.

Sorry for the snit I'm having right now.... I just cannot stand nonsense like this....

To say which does not detract in the least from the admiration I have for your wonderful essay/post, my dearest sister in Christ! Thank you so very much for your telling observations!

That is exactly what the notion means. If they'd think about it rationally, surely they'd realize how absurd it is.

Even some mathematicians believe they will someday create artificial intelligence capable of qualia (can be experienced but not conveyed such as love-hate pain-pleasure) because, after all, if the physical brain can produce qualia then so can a machine. LOLOL!

Thank you oh so very much for your insights, dearest sister in Christ, and for your encouragements!

There is no exact analogy for the soul-brain arrangement, but a radio wave from a broadcasting station seems close, where a wave is generated by design, and the wave travels to a receiver for translation into the sound intended for hearing; the radio/electromagnetic wave needs a receive tuned to handle the wave and translate it into sound/compression waves.

I very strongly agree with you, dear brother in Christ!

And to follow the analogy, just like injury to a radio will affect its operation but not the radio station's transmission - the injury to a physical brain will affect its operation in the body but not the soul/mind/spirit.
