Cosmology and Quantum Gravity: Loops and Spinfoams (Carlo Rovelli)

Lecture from the mini-series "Cosmology & Quantum Foundations" from the "Philosophy of Cosmology" project. A University of Oxford and Cambridge Collaboration.

I borrowed a book from my uni library by Carlo Rovelli, trying to learn LQG from it :)

... "Quantum Gravity *is* the theory of the minimal length... this is the core of the theory..."

[NaturalFuture]

It's an intriguing theory, however neither Rovelli nor Smolin seem to define the precise substance that each atom of space and time are made of. To describe one of space as lines and nodes which connect doesn't seem to be accurate enough. But, of course, loop quantum theory, as any other theory of physics, is a work in progress.

In the book, "Reality is not what it seems...", Dr. Rovelli says there are 15 different fields. I would like to know what they are, wasn't aware there were that many fields. If h= minimal information~ bit, could its length = LPlanck. Then the area of our brain could hold 10 to the 107 bits of information possibly even past present and future at the same time. I have a quantum computer sitting on top of my neck...TY

I keep losing perspective in conceptualising quantum physics. Its like falling down a hole further and further arriving in between quantum particles one minute then standing beside the sun the next at the end of the galaxy. The vastness become minute at the quantum level. Conceptualisation from both scales is needed all the time.

A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA. Time DILATION ultimately proves ON BALANCE that electromagnetism/ENERGY IS GRAVITY, as C4 is a POINT that is ELECTROMAGNETIC/GRAVITATIONAL (ON BALANCE) as SPACE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. E=mc2 IS F=ma. A PLANET AND a star thus constitute what is A POINT in the night sky !!! It ALL makes perfect sense. Gravity IS ELECTROMAGNETISM/ENERGY. ACCORDINGLY, I have ALSO fully explained the MATHEMATICAL UNIFICATION of Einstein's equations and Maxwell's equations (GIVEN THE ADDITION OF A FOURTH SPATIAL DIMENSION); AS E=mc2 IS F=ma. The Sun AND the Earth are F=ma AND E=mc2.

Sounds like you are talking about Partons or atoms of space.

It seems the lecturer does not understand physics...

Never going to get a YouTube partnership with this video. Why bother?

The First State of Quantum Gravity (or Dark Energy Field) is the Crystal Core we are entangled in - The Crystal Core of the Black Hole in the Universe "Above Us"

The Second State of Quantum Gravity is the Wormhole from this Universe to the Universe "Above Us"

The Third State of the Dark Energy Field is the Void. The Void is referred to as the Dark Energy State - Dark Energy is Space - Space is not empty nothingness, Space is basically a Superfluid Liquid Crystal Structure that forms up one half of the Universe - The Universe is a Binary system, You have "Space" or more precisely "Dark Energy" and you have Matter/Energy - their interaction is the foundation of the Universe, Time, Gravity, Etc

The 4th State of Quantum Gravity is the "Dark Matter State" - This is the State where the Galaxy creates a "bubble" around itself within the Void, where there is MORE Dark Energy outside the bubble that inside the bubble - All Matter/Energy is actively "PUSHING" on the Dark Energy Field with its Electromagnetic Energy - the Galaxy "pushes" against the force of the "Void" or the "Dark Energy State" with its Electromagnetic Radiation Energy - This Energy eventually decays and actually turns into more Space/Dark Energy!

The 5th State of Quantum Gravity is the Crystal Iron Cores of the Cosmos, the Stars, Planets, Moons and Protoplanets, the "Cores of the Cosmos" are Crystal Core Quantum Computers, These Cores use their Electromagnetic Energy and create a "bubble" around themselves, where there is MORE Dark Energy on the outside of the bubble than inside - the Cores of the Cosmos form up the "Surface" or the "Surface of Life" - Man, or the Humanoid is the Primal of 5 - the Evolutionary Descendant and form the Cores chose to create as their "vessels of flesh"

The 6th State of Quantum Gravity is the Surface of the Atom - There is More Dark Energy on the outside of the Atom than inside the Atom

The 7th, 8th and 9th States of Quantum Gravity are the Shells within the Atom

The 10th Quantum State of Gravity is the Black Hole, which leads to a new set of Quantum States of Gravity! The Crystal Core of the Black Hole leads to a new Universe - Universes within Universes

To understand this, how the Universe creates Gravity and Time, you need to understand that "Time" is the Interaction of Matter/Energy and Space/Dark Energy - so the MORE Dark Energy interacting with Matter, the More Time can occur

Gravity is the Electromagnetic Force Matter exerts on the Universe, on Dark Energy that creates a "Dark Energy Field Effect" or Gravity - what that means is that Matter pushes Space away from itself and Space pushes back, as each piece of Matter gets close to each other, their "Distortion Fields" touch each other and so this creates a "Path of Least Resistance" and Pushes Matter together - Dark Energy is Pushing all Matter together!

"Does Space have Density" - YES - That's why we have "Gravity Waves" - So, the Denser the "Space" (which is really Dark Energy) the more Time can occur, the less "Space" the less Time can occur

Motion of Matter Equals Gravity Equals Energy (Plus about 10%) - It's the very motion of Matter over the Dark Energy Field that creates the Electromagnetic Energy - so the FASTER MATTER IS MOVING THE HEAVIER IT GETS

The FASTER Matter moves, the the MORE Electromagnetic Energy it produces - therefore the more it pushes on "Space" and therefore the harder space pushes back - this is Gravity

The FASTER Matter moves, the MORE Electromagnetic Energy it produces - therefore the more is pushes on "Space" the LESS "Space" is interacting with Matter, and Therefore THE LESS TIME!

Glossary of equivalent identities(?) (nuanced).
(Actions speak louder than words)

Tautology, equivalent to the circular logic or multiplicity in meaning qualities of elemental terms?

The coordination of +/- possibility <=> probability,
or one eternal process of connection,
= integration-differentiation simultaneously,
(non-local connection, entanglement), in infinite-continuous rates and numerical-harmonic proportions. (Gauge theories)
=Totology of synchronous quantum events, or inflation-emergent phase space equivalent to the theoretical properties of the Big Bang.

Units-connections, are self-defined by the simultaneous identity of functional significance, ..singularity, duality, triple states etc, within the Wave function. (=Operators?)

Non-locatity is simultaneous-identity in discrete time, or, non-time, zero-difference.
