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

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.

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 wink
don't have time to watch right now, but I've put it on the 'watch later' list. smiley

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 ")

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.

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
of 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

                Dynamical 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).

youhn,
I believe that the geometry discussed in your posts above is that of the fractal error correction/prevention mechanism and not the geometry of the initial computational solution series that results in the non-experiential universe or its relationship/conversion to the experiential Universe.
