Some Half-Baked Thoughts about de Sitter Space - Leonard Susskind

[@123amsterdan456]

always love to hear Dr. Susskind speak

[@dankurth4232]

not regarding the topic?

[@psi.squared9448]

1:27:46 even made Ed laugh on camera with that, boy we need more Lenny Susskinds

[@neurophilosophers994]

It seems that this video was uploaded twice. I would love to hear the (hardcore) meeting that happened afterward. If it was recorded.

[@professord8888]

Excellent! Just what my mind kneads. This way they'll be fresh and chewy.

[@Daniel-ih4zh]

Jesus, all the big names made an appearance in this video.

[@ivocanevo]

Yeah... I just stumbled on this, I was not expecting a who's who of modern theoretical physics!

[@realcygnus]

Superb !

[@psi.squared9448]

You just gotta love how he comes on casually wearing his pajamas

[@naimulhaq9626]

Brilliant insight into fast scrambling and GR=QM. How do we arrive at the Plank level Schrodinger's wave function? Perhaps when Susskind is finished baking fully, or perhaps when Maldacena finds the algorithm of QC function.

Only few particle can exist in our universe due to syncronicity of mode of vibration if one note exist then it removes possibility for some others. Charge in string theory is of mode of vibration or note.quantum particle can be defined a string which has same length as diameter of quantum particle.

[@abhiastronomy]

Good explaination

There is nothing like hearing a pioneer and leader in their field say "so when I get insecure..." to make you feel ok in your own insecurities.

[@antongerin4932]

Thats just weird.,?!

[@poeutpoch9496]

Alice is designing a box 4"x4"x4". Then she send them to a 3D printer. She never look at the final product but send Bob to look inspect/measure the product. Bob measurement was 4"x4x2. But Bob never return to Alice. Who is right.

This concept was already demostrated numericaly and geometricaly in 2015 fqxi

[@stargenemolly]

Something to play with: In that "delta S =..." formula, all the S's scale with N particles, and N scales with mass. So, assuming the object at the pode is a classic BH, substitute Mbh and Mu (for de Sitter universe) when d=6 (and assuming compact C-Y dimensions). Assume that d=4 refers to Rbh and Ru, which scale as M. What then are the resulting delta R? and the delta M? Try using real values.

[@brendawilliams8062]

I love to hear the professor too. I just imagine with him. Not as smartly. Like is this pattern like the conjecture of poincare

[@knight3481]

Lenny looks better for his age. He looks younger than Ed though Ed is at least 10 years younger than him.

[@das_it_mane]

Is that parable not a religious idea? To value their beliefs over actual data?

[@johnphil2006]

Lions are marching again towards horizon.. interesting!

[@giakon1]

The concept of the de Sitter space and de Sitter universe, a solution for Einstein's general relativity in which there is no matter and a positive cosmological constant. This results in an exponentially expanding, empty universe. Is this helping in understanding what the universe is? This abstractism...!

[@davidwilkie9551]

Self-defining Singularity, aka holographic Quantum Operator Fields Modulation Mechanism cause-effect Principle.., positioning by pure relative motion is aka AdS/CFT, or real-time e-Pi-i-reflection containment connection. Perceptions of time-timing sync-duration identification equivalent to Space-time object orientation, ie projection-drawing of Geometric Orthographic Projection Drawing Principle Perspective is always going to be a coordination/orientation duality in which you can perceive either an object or an energy-thing objective, measuring system by symbolism. Ie, "some assembly required" in probabilistic temporal pulse-evolution coherence-cohesion objectives, the everyday business of Theorists. Eg The insideout version of a Black Hole is (de Sitter timedurationtiming), "size less" infinite/eternal time-timing sync-duration point positions, Mathematical identification .dt axial-tangential zero-infinity, Singularity.., which is No-thing space defined by quantization time-timing at Zero Kelvin.

when will you study Alain Connes and noncommutative phase? Basil Hiley. Louis Kauffman. Roger Penrose. All rely on noncommutative phase. good luck.

[@Florreking]

what u smokin

[@JamesHawkeYouTube]

Mathematics is not science. Change my mind. :)

[@merlepatterson]

There's a fine line between reserved genius and boisterous ignorance.

[@diamondisgood4u]

do you really think those are mutually exclusive?

[@merlepatterson]

@@diamondisgood4u That wasn't actually the premise and no, I don't think that. It lends itself to aligning with the Janus complex.

Points are dual to lines -- the principle of duality in geometry. Inclusion is dual to exclusion. Concepts are dual to percepts -- the mind duality of Immanuel Kant. The intellectual mind/soul (concepts) is dual to the sensory mind/soul (percepts) -- the mind duality of Thomas Aquinas. Mind (the internal soul, syntropy) is dual to matter (the external soul, entropy) -- Descartes. Gravitation is equivalent or dual to acceleration -- Einstein's happiest thought, the principle of equivalence (duality). Thesis is dual to anti-thesis creates the converging thesis or synthesis -- the time independent Hegelian dialectic. Hegel's cat: Alive (thesis, being) is dual to not alive (anti-thesis, non-being) -- Schrodinger's or Plato's cat. Being is dual to non-being creates becoming -- Plato's cat. Absolute truth is dual to relative truth -- Hume's fork. All of the above have a Janus complex! Syntropy (prediction, projection) is dual to increasing entropy -- the 4th law of thermodynamics. Teleological physics (syntropy) is dual to non-teleological physics (entropy). Teleo-phobia is dual to teleo-philia. "Always two there are" -- Yoda. "The Force" = Duality. Duality creates reality. AdS is dual to CFT.

[@JamesHawkeYouTube]

@@hyperduality2838 It seems you people really believe this shit lol.

[@hyperduality2838]

@@JamesHawkeKZbin Potential energy is dual to kinetic energy, gravitational energy is dual. Apples fall to the ground because they are conserving duality. Electro is dual to magnetic -- Maxwell's equations, electro-magnetic energy is dual. Photons, light or pure energy is/are dual. Energy is duality, duality is energy. The conservation of duality (energy) will be known as the 5th law of thermodynamics! Syntropy (prediction, projection) is dual to increasing entropy -- the 4th law of thermodynamics! The concept of duality allows me to create new laws of physics. Space is dual to time -- Einstein. Length, distance, space is defined by two dual points -- space duality. Points are dual to lines -- the principle of duality in geometry. Up is dual to down, in is dual to out, left is dual to right -- space duality. The future is dual to past -- time duality. We predict the future (syntropy) and remember the past. Absolute time (Galileo) is dual to relative time (Einstein) -- time duality. Time duality is dual to space duality. Action is dual to reaction -- Sir Isaac Newton. Nature, the universe, reality has a Janus complex! Energy is dual to mass -- Einstein. Dark energy is dual to dark matter. Certainty is dual to uncertainty -- the Heisenberg certainty/uncertainty principle. Duality is a pattern hardwired into physics, philosophy & mathematics etc.
