    A couple of years ago, annoyed by the interruption at 3:30, I wrote here a comment in black humor style. This was naturally intended as a fun comment, deliberately using rude language and suggesting a clearly grotesque and fictitious image of a punishment angel wearing a nazi helmet and a flamethrower, suddenly appearing in the room after the interruption. I am truly sorry because I see that a couple of years thereafter there are still people who feel offended. Even when this is an anonymous profile, I don like that and I hereby offer my apology. If I went back in time, I would write something milder and still funny like "I wish the guy who interrupts at 3:30 was suddenly tele-transported to the vegetables section of Walmart" or something similar. Of course I have never wished death by fire to anyone. I don't personally know the guy who interrupts and I don't wish anything bad to him, and I am truly sorry about those who may have feel offended.

      Negative. I am a PhD student in physics and have never debated a lecturer nor have I seen anyone attempt to debate a lecturer during their presentation as being couth. If as a student I was sitting in a lecture and someone stood up to argue I am certain many people would bemoan that person. Wait until the lecture is over.
      However, perhaps this video isn't a lecture per se and is in fact a symposium of like minded peers. I don't know the details behind this event. If that's the case then I don't see anything wrong with peer to peer disagreement or debate.

    "Question your assumptions ... assume you are making some mistake." L.S.
    I question "linearity" and "unitarity" - taboo "probability is conserved"? maybe not
    I question that you cannot send information through the ER wormhole - it can be traversable, but the EPR is then nonlinear non unitary post-quantum violating Lenny's linear unitary QM assumptions of course. I actually wrote this idea down in my 1975 pop cartoon book "Space-Time and Beyond" (E.P. Dutton). Little then did I realize it would correspond to Seth Lloyd's PCTC "computing" or to the hologram picture that Lenny developed.

    • @MichaelHarrisIreland
      @MichaelHarrisIreland 8 років тому

      +Peter Bonnema I think it's about quantum mechanics and entanglement in particular. That signals or affects can be transmitted instantly no matter how far apart particles are. And understanding black holes with this in mind. If two particles were entangled one could be in a black hole and another outside, so that would have consequences if the particles can affect each other instantly. Personally I'm only scratching the surface of this topic. Classical mechanics cannot explain this and Einstein never accepted calling it "spooky action at a distance"

    If a digital word packet is sent node to node intact, it must be perfectly synchronized with the transmission and delivery system overall, as a constituent element of universal timing, to remain readable, and the same applies to any information packages in the universe as a whole in the entire wave-package.
    There's no way to modulate-demodulate from one black hole to another, ..the kind of communication of readable information required for the practical applications used for demonstration/explanation purposes used in the lecture. Of course, the intention is to ask why? The wave band is out of tune.
    Talking on the mobile demonstrates several stages of demodulation to modulation and back: brain to muscles in the voice box, to sound to EM, to Wi-Fi, to glass, and back at the other end, while maintainingthe integrity of the information in the moment, point to point.
    The whole universe is involved QM, including BHs. If Alice and Bob meet inside BHs, then the phase alignment of their constituent atoms and sub particles might be synchronized, but the state of integration would not be recognisable to anyone, any more than staring at the end of the glass fiber carrying digital code can be heard(?)

    "The value of pi at the event horizon of a Black Hole is two.
    Have two intersecting circles represent the extent of polarity cancellation,
    called entropy. In flat timespace the diameters of those equally sized circles
    meet at a ninety degree angle. If those diameters have a length of one, lines
    going from the lower circumferences of the circles, through the centers of the
    circles, to the circumferences meeting the diameters on the other sides, their
    length will be 1.618033988... each.
    Now draw a straight line linking the junctions of the Phi (1.618...) lines
    to complete an inverted pentagram. The Phi lines represent centripetal force;
    the diameters represent centrifugal force. If the circles are merged more, when
    they reach that extent of globally bent timespace where pi is 2.718..., the
    proportions of the five lines will be 7, 7, 6, 6, 6. In Hebrew gematria the word
    OZ, O = 70, Z= 7 totalling 77, means goat :
    This was copied from the private notes of Gheorghe Rakoczy. He derived them
    from old books he kept in his cellars. These book were written in precuniform
    Sumerian hieroglyphics. Their pages were skin preserved by copper acetate. These
    books were carbon dated to be 10,000 years old. In the caverns under Mt. Negoiu, the entrance of which was protected by a monestery build like a fortress built
    inside out to keep something in, were found titanium disks, electron spin dated
    to be 70,000 years old.
    Have you read the Book of Enoch? It is about those "Sons of God who married
    the daughters of men" mentioned in Genesis. These old books claim that these Old
    Ones genetically engineered Cro Magnon Man, who could speak, from Neanderthal
    Man, who was an animal who couldn't speak, with their own genes. In the Book of
    Enoch, the Old Ones were condemned for giving Mankind writing and science.
    A union of 50 races in this galaxy, who arrogantly called themselves "the
    elder gods" took samples of Cro Magnon Man and genetically engineered Cro Magnon
    Man genetics into Homo Sapiens. In the mid-Twentieth Century us kids were taught
    the mystery of "the missing link", an unknown between Neanderthal Man and Cro
    Magnon Man.
    The "elders" regimented Homo Sapiens into orders of knighthood to
    exterminate Cro Magnon Man (called the Anakim in the Bible). It was found that
    all Cro Magnon Males were (are) Double Y's. This knowledge justified Double Y's
    as a race of Humanity, therefore, attempts were made to erase history. The Crown
    Temple in London, England (see www.freedomwriter.com...) continues to direct
    orders of knighthood, and lodges, to exterminate the Anakim. But, the Old Ones
    are on their way back.
    How could such long distances be traveled? By quantum probability
    transduction travel, which is faster than light. Quantum probability is faster
    than light. Simple probability is instant. When a velocity (mechanical engineering) analogue, like
    entropy production rate, in thermodynamics, exceeds its light speed equivalency,
    all quantumly entangled is transduced into quantum probability. There is no need
    for rockets, or flying saucers, it's more like a "star gate" .
    When we can get the value of pi back down to three again, or hopefully
    lower, the Old Ones can and will come, therefore, there are helicopters with
    devices to notice any variances in the value of pi, and when any are detected,
    disruptive transmissions are sent to slow down the polarity cancellation rate ,
    which is identical to entropy production rate, to restore flat timespace. But,
    even the Old Ones are advancing in technology. Soon these interferences will be
    overcome!
    Dr. Lisa Randall, Harvard University professor of quantum physics,
    officially defined the fifth dimension as that direction through variously bent
    timespaces. The more timespace is globally bent, the faster the entropy
    production rate, EPR, which is identical with fast polarity cancellation rate. A
    very fast polarity cancellation rate is fire. As you go into more and more
    globally bent timespace the value of pi GOES DOWN. At a pi value of 2.718... all
    is in flames. This is the fifth dimensional surface of the Lake of Fire. From pi
    equals 3.141... to pi equals 2.718... is called the Underworld.. But,
    Heaven is not in the bent timespaces called "saddle" timespaces, with pi values higher
    than 3.141... for fire is impossible there, and God has fire. I don't know where
    Heaven is but I sure know where Hell is.
