Lawrence Krauss - Why is Quantum Gravity So Significant?

Quantum theory explains how particles and fields work. General relativity, discovered by Einstein, explains how gravity generates the structure of the universe. But the two great theories of physics and cosmology are not compatible. But this is impossible because both describe reality. Only a solution to quantum gravity can solve the huge problem.

    01:36 This exact property of time is so interesting, it keeps me comin' back to Krauss, but TIME EQUALS THE DELAY IN TRANSITORINESS. He explained that in the Coincidence of Design, the moment stars, planets (matter) was able to form and stay in that form. That = Exactly what time is. He says it so brilliant, ofcourse Einstein was smarter than Krauss, but no one beats him on the phenomenom: TIME.

    Everyone should read Ted Jacobson’s 1995 paper,”Thermodynamics of Spacetime: The Einstein Equation of State”. The key line is, “By analogy, the viewpoint developed here suggests that it may not be correct to canonically quantize the Einstein equations, even if they describe a phenomenon that is ultimately quantum mechanical.” Freeman Dyson said he had calculated that a detector sensitive enough to sense a single graviton would have so much mass that it would collapse into a black hole. He speculated that gravity is intrinsically classical. The search for quantum gravity may be fruitless. We need someone of the caliber of Kurt Goedel to show that. We’re still waiting for Goedel.

    If you look into Wolfram's model of physics, i actually think his model is a true theory of everything because it does that what you said. It unites Gravity and Quantum Mechanics by emerging them from a notion of fundamental computation. When you think about the universe in this way...EVERYTHING changes and shifts in perspective that is truly mind-blowing. I've studied his model for about a year, and before that i studied Complexity Theory which led me inevitably to his model. When you think about the universe as a computation, those computations create systems that are complex and it's this complexity that emerges the bulk properties of spacetime, the bulk properties of quantum mechanics, AND it says something hard about the role of observers in such a universe when viewed as computation.

    I'm confused by what you mean Einstein relied on great experiments to come up with General Relativity and that science does not come from people thinking in a room. Einstein was renowned for his "thought experiments" which requires thinking in a room and that is what he used to describe General Relativity to the people around him and support his hypothesis. The experimental data that came after is what validated his hypothesis and what transformed General Relativity into our best understanding of the Theory of Gravity. A better way of putting it is that thinking is what gives you a hypothesis and experimenting is what validates your hypothesis to make it a theory.

    One key story was actually a discussion he had with a house painter. The painter had fallen off the roof. He told Einstein that as he fell, he did not feel gravity. Landing was a different story. Einstein thought about the house painter's physical experience quite a bit as he eventually developed the principle of equivalence. He did create specific thought experiments that are all connected to not being able to tell the difference between gravity and being in an accelerating reference frame. I know of no story in Abraham Pais's book "Subtle is the Lord..." a scientific biography of Einstein that would give credit to lab experiments on the path to GR. Rather, this is just a little verbal imprecision by Krauss. The precision of the perihelion data was already there. Einstein was giddy for a few days when he saw the Schwarzschild solution to the GR field equations was able to get that result. Clearly that was after. There is some question as to how good the 1919 solar eclipse data was to make the case for GR over Newtonian gravity.

    The most intuitive way to explain how or why a particle like a photon (or electron, etc) might behave as an uncertain location particle while also like a polarizable axial or helical wave ''packet'', given that everything in the universe from electrons to solar systems are in orbit with something else pulling them into polarizable axial or helical apparent waves depending on the orientation of their orbits as they travel thru space is that they’re in orbit with an undetectable dark matter particle pulling them into polarizable axial or helical apparent waves as they travel. And given that we know we’re in a sea of undetectable dark matter but don’t know where it’s disbursed, we can imagine that they’re in orbit with an undetectable dark matter particle pulling them into polarizable axial or helical apparent waves as they travel where the speed of their orbit determines the wavelength and the diameter is the amplitude which would explain the double slit, uncertainty, etc. No?

If you break matter down as far as logic goes, you can break a given thing down small enough to create a magnetic semimonopole, giving you NL, NR, SL, and SR. These would attract each other as legitimate building blocks for particles like muons. Other monopole particles would align with bigger magnetic fields, like a compass needle. As that mass takes shape, gravity comes into play.

    I don't think I've heard a deal definition of what is "Quantum Gravity". On the macro level we say that gravity is the bending of space/time in the presence of matter. When we get down to the quantum level do quantum fields exist as they do at the macro level? Do we even know enough about the quantum level to that matter even exists at the quantum level or is there only energy which would not necessarily bend space/time? If I shoot a laser from here to the moon does the laser bend space along it's path? I think we don't know enough about the quantum level to even assume that such a thing as quantum gravity actually exists as we define 'gravity'.

    Quantum gravity with dark energy comes out like this; all matter in the Universe around itself excite quantum space for expansion (pulsing by quantum oscillations of waves). But at the same time, the bodies, opposite each other, create wave interference with the expansion of the quantum space, for this reason, the pressure of the quantum space between the bodies will decrease, as a result of which the quantum gravitational attraction of the bodies arises ....

    What I don't like is the math tells us one thing but the fact is we don't really know whats going on... why do they ignore spooky action at a distance? For me this is as mind blowing as a black hole as it defies everything in physics. Yet these scientists just carry on their rhetoric of shut up and math.

    While quantum mechanics might be about phases and phase shifts, the classical and relativistic physics (including gravitational waves) might be about condensed matter? If so, ought not the mathematicians explore different methodologies to combine the two? Of course the mathematics would break down and the results would be nonsensical because the two fields are incompatible to start with. Just as Newton had to invent calculus to describe gravity, mathematicians may have to invent a new field of mathematics to unify these two. Why am I pointing out something so obvious?

    Quantum mechanics is outside of Einstein's time-space wherein dark matter and energy come iinto place because their gravity and expansive effects fit into a mathematica model. Or is he, we or I missing something? There are two seemingly contradictory physics at work. String theory is an act of faith and I think quantum physics, in its indeterminancy and uncertainity is also.

    Quit being pedantic. Or worse, deliberately obtuse. He just means to reiterate the point he and other physicists like Sean Carroll have made: we've come up with a theory that explains, predicts, and describes virtually everything that occurs in our daily lives, and even obscure technological fields like space travel, geophysics, biophysics, and virtually all current forms engineering (maybe with the exception of quantum engineering - does that even exist?). Sure it's important to keep in mind that there's a lot of Dark Matter or whatever in the universe but it is irrelevant to all forms of current technology - certainly much more than 95% of human experience.

    When is the beginning of the universe might be like asking where is the beginning of a circle? Nevertheless, my pet notion is that our universe is "digital" (the Planck constants being the individual "bits") and there was no "zero". And time is a quantum "click" that arises out of the fact that matter/energy transitions from one state to another in quanta. In our universe, time is one way. The concept of time wouldn't make sense if it weren't one-way, it's a kind of "valve" that prevents anything from happening in reverse. Gravity might be positive and negative, but time is always positive - at least on the macro scale (which may be quite small, anything more than a few nanoseconds, say). But there may be other universes where it isn't (or wasn't) and they either didn't develop into anything or quickly evaporated into nothingness (or maximum entropy). A kind of natural selection where universes that didn't have fluctuations of energy or one-way time or weren't quantized (or were quantized too small or too big) became extinct. Our universe is probably one of the very few "Goldilocks" universes that survived. There may be multitudes, but they either don't coalesce into something that clumps into existence or they are simply void without form. But (if that's the case) then that begs the question: what is the nature of this multitude of universes and pre-universes or universe "ingredients"? And how did that all get "started" (if that word means anything, that is)?

    So from my layman understanding, there are two reasons why quantum gravity is important.

    Einstein said: "A law is more impressive the greater the simplicity of its premise. The more different the priciples to which it relates. And the more extended its applicability". Therefore, thermodynamics is the one theory of universal content which will never be overthrown." Richard Feynman said if he could not teach a theory to a freshman class, it was lacking in sufficient rigor. Contrast that wih Roger Penrose' kitchen-sink gobbledegook. Penrose confoms to a model of physics which suggests that the discipline is capable of answering all questions of the universe.... as opposed to the absolute comprehensibility and sustainability of Anton Zeilinger's team parsing quantum entanglement. As razor-thin was his contribution, Carl Sagan nontheless knew thermodynamics utterly confuted his life-long insistence that "ETs" would answer all questions. His "contribution" to actual science was, "it's not at all clear that thermodynamics is universal". He knew he had to make a ROTFLMFAO attack on thermodynamics or have his sine qua non refuted. WTF OTHER "science" is cadged as : "it's not at all clear"?! Other than the "secrets" he alone is privy regarding undergraduate girls he is accused of inappropriately approaching, Kruass is nothing other than a 'physics beard' for Richard Dawkins. Impossibly , Kruass actually may have superior physics tO Dawkins, whom said (1st page Chapter 4, "The God Delusion") regarding Fred Hoyle's "Life originating on earth is as likely as a hurricane assembling a Boeing 747 out of a junkyard": Hoyle fails to sufficiently appreciate natural selection". HOWL!!!! SCREAM!!! DAWKINS THINKS NON-BIOLOGY RESPONDS TO NATURAL SELECTION...SUBVERTS 2LTM!!!

    Excellent interview, but more admirable is that it concludes that the approach to new theories requires experimentation and demonstration as established by the scientific method. The idea that you only need paper and pencil to have a brilliant idea in discovering the secrets of the cosmos is false. Albert Einstein raised the Theory of Relativity using only his mind but his theories and that of many others are incomplete including Quantum Mechanics.

    Could be there is no gravity at quantum scales. This is much like there is no beetle behaviour at the molecular or atomic level of the beetle. So asking what is the beetle behaviour exhibited by each atom that makes up the beetle? Clearly there is none because it takes all the atoms of the beetle before behaviour materialises from the beetle. Similarly it takes a full universe before gravity emerges.
