Title: Physics - the geometry of space Post by: youhn on January 25, 2017, 07:57:55 PM While looking into the quantum entanglement subject, connected to wormholes, I found one of my heros drawing a fractal structure of space. Some bits of quotation from the video (2 jan 2017):
vacuum empty space an instance of time lets draw space break up space into a lot of cells lets first divide it in half divide it into cells tessellate it with little cells near the boundary near the edge which separates the two regions the same size as their distance from the dividing line move out a little bit draw slightly bigger cells twice as far and twice as big draw bigger ones divide space into a scale invariant way or at least in a self similar way https://www.youtube.com/watch?v=rpwZ02WbxvQ Some related quotes from an article (july 2016): "Most importantly, we’ve assumed that parts of Hilbert space that are highly entangled are also “nearby,” but we haven’t actually derived that fact. It’s certainly what should happen, according to our current understanding of quantum field theory. It might seem like entangled particles can be as far apart as you like, but the contribution of particles to the overall entanglement is almost completely negligible — it’s the quantum vacuum itself that carries almost all of the entanglement, and that’s how we derive our geometry." The structure of space seems to be created entanglement, which is caused by particles (or interference patterns in the waves, if you like) moving away from each other. Now image all particles randomly moving through space (for example the early universe), which creates a interwoven web of entanglements. Due to small variation, some groups of particles form more entangled webs. This more dense web of entanglement causing the warping of the geometry of space on larger scales, gravity. Those entanglements on the scale of particles are tiny wormholes ( ER = EPR ), so the structure of space is made of intervowen tiny wormholes. This explain why time on the quantum scale has little meaning, as it only arises on the macro scale. Time on the quantum scale would only make sense if we would exactly know the geometry of the wormhole-web structure (which I think is quite impossible). Forget the Euclidean worldview and try the dynamic, chaotic and most likely fractal structure of space. Other views on the structure of space are more than welcome! Please share any visualizations on the subject that you might find. Title: Re: Physics - the geometry of space Post by: Chillheimer on January 25, 2017, 08:12:32 PM thank you for sharing! I'Ve wathced quite a few talks of susskind already.
He sometimes uses different terms, but his thinking is very fractal-ish ;) don't have time to watch right now, but I've put it on the 'watch later' list. :) Title: Re: Physics - the geometry of space Post by: youhn on January 25, 2017, 08:34:55 PM Still zooming in
now just watching this ( "he ecxiting thing about this is that we might get gravity for free if you imagine distances are defined by entanglement and you modify the state a little bit and the distance automatically gets modified what happens is that the spacial curvature is proportial to the modular hammiltonian you get a spacial relation rather than taking classical geometrical theory and quantizing it, we're looking in the wave function asking how space emerges and of course the geometry of that space if going to response to changes in the state ") https://youtu.be/AUiMi3GHxYw?t=15m15s Title: Re: Physics - the geometry of space Post by: youhn on January 25, 2017, 08:57:22 PM Imagine what you would experience if your body shrinks.
If you don't feel yourself shrinking, then perhaps you would say the world around you expands. We observe an expanding universe. Could this in fact be the result of all things getting smaller? Or if you project this onto a fractal structure of space, is it the result of the smaller patches getting smaller instead of the whole getting bigger? The view from one of those patches would result in the same effect as the whole space expanding. Title: Re: Physics - the geometry of space Post by: youhn on January 29, 2017, 11:27:57 AM New observation on the nature of geometry/structure of space(time): Quote Usually when a material is in ground state, also known as the zero-point energy Source: http://www.sciencealert.com/scientists-have-just-announced-a-brand-new-form-of-matter-time-crystalsof a system, it means movement should theoretically be impossible, because that would require it to expend energy. But Wilczek predicted that this might not actually be the case for time crystals. Normal crystals have an atomic structure that repeats in space - just like the carbon lattice of a diamond. But, just like a ruby or a diamond, they're motionless because they're in equilibrium in their ground state. But time crystals have a structure that repeats in time, not just in space. And it keep oscillating in its ground state. Imagine it like jelly - when you tap it, it repeatedly jiggles. The same thing happens in time crystals, but the big difference here is that the motion occurs without any energy. A time crystal is like constantly oscillating jelly in its natural, ground state, and that's what makes it a whole new form of matter - non-equilibrium matter. It's incapable of sitting still. But it's one thing to predict these time crystals exist, it's another entirely to make them, which is where the new study comes in. Yao and his team have now come up with a detailed blueprint that describes exactly how to make and measure the properties of a time crystal, and even predict what the various phases surrounding the time crystals should be - which means they've mapped out the equivalent of the solid, liquid, and gas phases for the new form of matter. And the summary from the pre-print paper: Quote METHODS SUMMARY Source: https://arxiv.org/pdf/1609.08684v1.pdfDynamical decoupling sequence. We use a pair of Raman laser beams globally illuminat- ing the entire ion chain to drive qubit rotations22. The ion chain has 25 µm length, and we shape the beams to have 200 µm full width half maximum along the ion chain, resulting in 5% intensity inhomogeneity. When a fixed duration is set for H1 in Eq. 1 of the main text, the time dependent magnetization for different ions ac- quire different evolution frequencies, resulting in the net magnetization of the system dephasing after about 10 -pulses. In addition, the Raman laser has rms inten- sity noise of about 1%, which restricts the spin-rotation coherence to only about 30 -pulses (80% contrast).
