Time and Consciousness (quantum theory and going backwards in time)

                    -equations of physics have time reversal symmetry

                    -time may only exist in consciousness - sense of "now" connected in memory, but outside consciousness there is no "flow" of time

                    -consciousness gives classical world flow of time. quantum world time does not flow

                    -two particles in superposition and entangled

                                         -separate the two and make a measurement of one and the other instantaneously reduces to the complimentary situation

                                                              -this means there is instant communication (faster than the speed of light)

                                                                                   -speed of communication is prevented by relativity, so "quantum" information goes backwards in time to when the particles were                                                                                     unified and then forward in time to the now separate particle

                    -time travel causes paradoxes

                                         -grandfather paradox

                    -if a tree falls and no one is around...

                                         -answer depends on interpretation of quantum mechanics

                                                              -copenhagen - no: quantum superposition of multiple possibilities and tree does not fall unless someone observes it falling

                                                              -decoherence - yes: it collapses to one possibility

                                                              -objective-reduction - yes: it has reached the threshold for collapse

Second Law of Thermodynamics

                    -things unwind and move forward - arrow of time does not hold true in the micro/quantum world

                    -time is symmetrical on classical level - electromagnetic information goes forwards and backwards

                                         -backwards information is only perceived by a coherent observer (maybe consciousness?)

What is Consciousness?

                    -self-collapse of wave functionality

                    -natural state of the quantum world - quantum superposition (superposition of multiple states of locations)

                                         -copenhagen - conscious observation causes collapse of wave function

                                         -multi-worlds hypothesis - every superposition branches off and forms a new universe

                                                              -interaction of superposition with environment causes decoherence

                                                              -superpositions grow until they meet threshold that causes the switch from quantum state to classical

Creating Your Own Reality

                    -a superposition reaches "threshold"  and self collapses and chooses a reality at that point (multiple choices/possibilities)

                    -plutonic information embedded in fundamental level of universe helps to influence the choice that is made (only in objective-reduction)

Classical and Quantum Physics (two sets of laws to describe the universe)

                    -quantum world - superposition/multiple possibilities

                    -classical world - collapse of wave function

                    -curtain between two worlds - mysterious

                    -consciousness - process in fundamental space-time geometry (everywhere in universe)

                                         -protoconsciousness (subconsciousness) exists at the fundamental level of space-time geometry and is everywhere and always was, always is and always                                           will be
