The first few decades of the 20th century was a time of miracles for physics. First, Einstein’s relativity utterly changed the way we think about space, time, motion and gravity. Then the quantum revolution of the 20s and 30s overturned all of our intuitions about the subatomic world. Together, general relativity and quantum mechanics have allowed us to explain nearly every fundamental phenomenon observed, and have predicted many unexpected phenomena that have since been verified. And yet the two theories contradict each other in fundamental ways. In the century since that golden era of physics, we’ve been trying to reconcile the two … without success. But today on space-time I’m going to begin our discussion of the great quest for this union - the quest for a theory of quantum gravity, and for a theory of everything.

    Stephen Hawking has theorized in the zero-energy universe, which is based on the idea of the law of energy conservation, that the total of all energy in the universe equals to zero. What he gives as an example is a person wanting to turn a flat piece of land into a hill by digging earth/dirt out of a hole. The hill in its totality represents positive energy or matter, the hole being the inverse or negative version in volume of the hill represents negative energy or space. Hawking theorized that negative energy may be gravity which increases negatively in proportion to the amount of mass of positive energy or matter, the heavier something is the more gravity it produces. But I personally have a different idea. Current astrophysicists theorize that there is a substance called dark energy, which is said to be a repulsive force, that is increasing the expansion of the universe. They also have a theory of dark matter, or matter that is invisible and acts a binding agent or gravity to keep galaxies from falling apart. There is also the postulation, or idea, of most of the volume of an atom or particle being empty space, and this reminds me of the idea that only 5 percent of the universe is meant to have ordinary matter, the next 23 or so percent being dark matter, and the rest being dark energy. Now I theorize that given the ratio of matter to space in a particle or atom, it seems awfully similar with the idea of most of the majority of the universe being dark substances. Now if Hawking is correct that space is negative energy and negative energy allows gravity, how can we reconcile these opposing theories? Well what if space, negative energy, was dark energy and dark matter? If space is expanding, then space fits with dark energy being a repulsive force, but I don’t believe all the negative energy is repulsing in only one direction. Dark energy surrounds galaxies, and thus in expanding outwards, would also press upon galaxies and thus physical objects like matter or positive energy, this pressure leading to a multiplied or ‘dense’ although ‘dense’ is not really the right word, but an increased or maximized form of dark energy compression, which could behave like a congealed form of dark energy, and thus be mistaken to be dark matter. This repulsive force or dark energy upon these physical objects of positive energy would thus become the force of gravity. The maximized negative energy would increase the repulsive force, and thus increase the force but decreasing the pressure (as there is no physical matter) against the physical matter object, and this could be what we feel as gravity. The multiplying decrease of pressure being negative energy, would thus feel less the further away from the postive energy object, but would increase the closer you came to the physical positive energy object, which causes the increase of gravity and thus creates acceleration of nearby objects towards the positive energy matter. I also theorize that since space is within an atom or a particle for that matter, the fact that this space is negative energy or dark energy may explain something. What if the particle was basically a type of positive energy matter force-field around a body of negative energy. The negative energy or space pushes the positive energy/matter outwards so it doesn’t collapse from outside pressing negative energy or dark energy into a singularity, and thus causing that matter to collapse into a miniature black hole or something similar. The fact that the particle remains in a spherical shape is because the positive energy is pushed back and forth between the external dark energy and the internal dark energy, which is why a particle resembles a sphere when observed in a scanning tunnelling electron microscope. But isn’t a particle also a wave? How does that work into this theory? The equal force from the internal dark energy and the equal force from external dark energy makes the positive energy matter become the spherical shape, but if this particle was say in a more dense or less strong surrounding dark energy, the particle could expand and spread into a field flowing in all directions until reaching the force of dark energy, thus becoming a wave of probability. I believe that when this wave is disturbed by either increased dark energy forces or that enacting upon a nearby positive energy matter body, or is observed the wave can then collapse into a particle. Because the wave is spreading everywhere, the collapse of the wavefunction would appear to be random, and thus be made out of a field of uncertainty, but to me its like recording old analog TV static on a VCR and then hitting pause, trying to position where that next piece of static will be. It happens so fast and there are so many probabilities affecting it that it appears random. Now I want to talk about another topic that may be related: String theory and M-theory. Superstring theory theorizes (hence the name) that particles are made out of small slithers of waving positive energy/matter string. Now strings can appear as single strands like a piece of string, or can appear as a loop of string. Now according to M-theory built upon superstring theory strings can expand into sheets called membranes or branes for short, which to me could form into physical shapes, like perhaps a sphere. It has also been suggested in particle-wave duality that all matter or positive energy is made of vibrations. Now just as particles can expand into waves, I see a correlation between the string and the particle, and the membrane as a wave, call it a string/particle-membrane/wave duality or string-membrane duality. The particle is simply the membrane of a string spread evenly around the negative energy thus forming the matter/positive energy force-field. They say that strings vibrating in different ways can create different particles. Now here’s where something else comes in: The Higgs Boson. The Higgs Boson is the particle of the Higgs Field which creates mass of particles. Remember when a motorboat would travel through a large lake or sea and there would be drag created by say a skiier holding onto a rope connected to the boat? Well I believe that as particles move through this Higgs Field, they create a drag which causes the appearance of mass. Now there have been detected two particles of the same size but each with very different masses. Now how can this be? Well there would be a reason for the particle to drag through the Higgs Field, and this is energy density. Suppose the string or vibration that made up the same size but incredibly light particle was a very long extended vibration, like say the frequency of a radio wave. The same size but incredibly heavier particle would have a very high narrow vibration, like say the frequency of a gamma ray. The increase in frequency leads to an increase in energy density, and how that particle’s charge through relation with the photon, and spin with the Higgs Field and dark energy, leads to the different interactions of various particles. It’s all the same positive energy, just different packets of it with different frequencies and different sizes. Now the collapse of these waves into particles to me also has another application. If you don’t know, there is an intense debate between trying to link quantum mechanics (which is how particles interact and behave as bits of energy) and general relativity (which is about how gravity affects large objects like moons, planets, stars and galaxies). Now quantum mechanics says that when a wave is being observed, it collapses into a particular spot and hence becomes a particle. Now General Relativity says that objects with mass or postive energy, basically, warp the space and time (as time is also a measure of distance and distance a measure of the time taken to cross that distance) thus causing nearby objects to fall into the warp of space time and thus become attracted to the physical matter object. What if this wave affected by dark energy or a nearby mass of positive energy, was the same as the positive energy or planet or physical object affecting the negative energy containing the space time? Thus this would link the effect of General Relativity warping space time (what I call macro negative energy mixed with the Higgs Field), the same time how space time and Higgs Field and negative energy (micro negative energy and Higgs Field) causes the collapse of wavefunctions into particles? Thus this would link General Relativity and Quantum Mechanics regarding the Collapse of the Wavefunction, the former being simply a larger version of the latter, one happening on a macro scale, the other on a micro scale. I hope that explains things, and I hope it has helped you answer those questions. Now if I’m wrong or right, please let me know. I’d like to know. Peace.

    THE THEORETICAL, SIMPLE, ULTIMATE, CLEAR, LINKED, BALANCED, AND EXTENSIVE MATHEMATICAL UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE IS PROVEN, AS E=MC2 IS F=MA: Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. The perpetual motion of THE PLANETS in RELATION to WHAT IS THE SUN is the result of the fact that gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, as this IS proven by F=ma AND E=mc2. GREAT !!!! ACCORDINGLY, a given PLANET sweeps out equal areas in equal times; AS GRAVITY IS ELECTROMAGNETISM/ENERGY. THEREFORE, this NECESSARILY represents, involves, and describes what is MOTION AND NO MOTION IN BALANCE. SO, THE SPEED OF LIGHT (c) IS THEN understood as a POINT; AS the SPACE that envelopes THE EARTH IN BALANCE IS the MIDDLE DISTANCE in/of SPACE. E=mc2 IS F=ma, AS time DILATION ULTIMATELY proves that electromagnetism/ENERGY IS GRAVITY. (BALANCE and completeness go hand in hand.) Gravity IS ELECTROMAGNETISM/energy. Indeed, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS ELECTROMAGNETISM/energy is gravity. Again, E=mc2 IS F=ma. OVERLAY what is THE EYE in BALANCED RELATION to/with WHAT IS THE EARTH. NOW, LOOK at what is the translucent, semi-spherical, AND BLUE SKY. THE EARTH is ALSO blue. SO, objects fall at the SAME RATE (neglecting air resistance, of course); AS E=mc2 IS F=ma; AS electromagnetism/ENERGY IS GRAVITY. Great. Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/ENERGY IS GRAVITY. This is proven by F=ma AND E=mc2. Indeed, a PHOTON may be placed at the center of THE SUN (as a POINT, of course); as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT (c). GREAT. ELECTROMAGNETISM/energy IS gravity. This is proven by F=ma AND E=mc2. "Mass"/energy involves balanced inertia/inertial resistance consistent with/as what is BALANCED electromagnetic/gravitational force/energy, as electromagnetism/energy is gravity. Gravity AND electromagnetism/energy are linked AND balanced, as electromagnetism/ENERGY IS GRAVITY. ACCORDINGLY, gravity/acceleration involves balanced inertia/inertial resistance; as gravity IS ELECTROMAGNETISM/energy. The stars AND PLANETS are POINTS in the night sky. Objects fall at the SAME RATE (neglecting air resistance, of course), AS ELECTROMAGNETISM/energy is gravity. E=mc2 IS F=ma. Gravity IS ELECTROMAGNETISM/energy. Carefully consider what is THE EYE along with the falling man. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. This is proven by F=ma AND E=mc2. (E=mc2 is directly and FUNDAMENTALLY DERIVED FROM F=ma, as ELECTROMAGNETISM/ENERGY IS GRAVITY. That is where Einstein got it from.) This NECESSARILY represents, involves, AND describes what is possible/potential AND actual IN BALANCE. THOUGHTS are invisible. Very importantly, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which thought is SIMILAR to sensory experience. SO, BOTH equations apply to, represent, AND perfectly describe the MIDDLE DISTANCE in/of SPACE as invisible AND VISIBLE ELECTROMAGNETIC/GRAVITATIONAL SPACE in FUNDAMENTAL equilibrium AND BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The BALANCE of being AND EXPERIENCE is essential. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Consider THE MAN who is standing on WHAT IS the EARTH/GROUND. Touch AND feeling BLEND, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense. Take careful notice of WHAT IS THE ORANGE SUN. Beautiful. Now, carefully consider the role and RELATIONAL significance of what is the eyelid. Consider what is lava. The viscosity of lava is BETWEEN that of what is water AND what is the Earth/ground. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. ELECTROMAGNETISM/energy is gravity. Time DILATION ALSO ULTIMATELY proves that GRAVITY IS ELECTROMAGNETISM/ENERGY. E=mc2 IS F=ma. Indeed, this not only explains the term c4; but it ALSO explains the significance of the fourth spatial dimension. GREAT !!! Notice that THE DOME of a person's EYE may also be visible. THINK. IT IS CLEARLY PROVEN. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. The stars AND PLANETS are POINTS in the night sky. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper understanding of physics/physical experience, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS the rotation of WHAT IS THE MOON matches it's revolution. Moreover, objects fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper understanding of physics/physical experience, AS ELECTROMAGNETISM/energy is gravity. Ultimately and truly, time is NECESSARILY possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (E=mc2 IS F=ma.) This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The INTEGRATED EXTENSIVENESS of thought (AND description) is improved in the truly superior mind. THINK. Gravity IS ELECTROMAGNETISM/energy.

    A universe can contain infinite information. Evidence: our universe is expanding due to the white hole in our universe which is getting information from its other side, a black hole our (previous universe). Black holes takes the information it has, makes space within itself, floods that universe with information. Entropy is beautiful.

    I keep returning to this and many other SpaceTime videos over time and there's always something new or previously unnoticed thing to discover or maybe rediscover:) Great source of knowledge and inspiration. This time it was the fact that unlike the other field theories where the physical-mathematical phenomena take place against the background of a coordinate system (space), that background in GR is spacetime itself, that is the very thing the theory is built on. So it becomes much more tricky to quantize gravity as you have to have some spatial background for a quantum theory to operate on - in its current form at least. That's why quantum loop gravity tries to do away with that background dependence, unsuccessfully yet.

    I liked Sean Carolls approach to this. He said instead of quantizing gravity you CAN actually "gravitize" quantum mechanics. Your spacetime is entangled with the rest of the spacetime (the closer they are the more entangled) and if you assume that, general relativity naturally pops out of the Schrodinger equation (supposedly). It sounds too good to be true to me though...

    The whole "become smaller than the sum of the originals" actually makes sense if you don't think of those numbers starting as positives but rather negatives (ie -lightspeed), if they start as negatives then a simple subtraction (destruction on collision) results in a positive instead of a negative, this positive is what we observe and misunderstand as going smaller when in fact it has gone larger.

    I meant that this hunt for Theory of everything feels similar to Hilbert program and one day some Gödelike physicist might prove that it's impossible to come up with a theory that explains everything at the same time. It has some similarities - theory is a model that can't capture everything unless the model is the universe itself. So we derive abstractions which simplify the model and that I think is the key - some abstractions are not compatible. So what if it is impossible to find combination of these abstractions in a way that explains everything? That's just my feeling though :D I only noticed similar pattern. If we find the theory, I am okay :D

    panstromek The problem isn't that we can't come up with a suitable (math/physics) theory that explains everything together - it's that we can, we have, and validation is so difficult (an understatement) that it takes a lot of effort (read: long times) before discovering that the explanation was wrong, and we've been doing that repeatedly for over a century. Along the way we've invented and discovered new tools and encountered new information leading to new questions than we had at the beginning of each particular cycle of effort. When it's done - assuming success some day - we won't be done. We'll simply have hope that we'll know which of the next round of questions are valid. In the meantime, we'll always have 42. PS - Of course when I said that we've been doing this for over a century, I was referring to just this one aspect, GR vs QM. If you go back to the century before that, we had the atom and the ether and we were this > At each epoch the temptation to call it a day popped up. It was often accepted. That didn't ever solve anything and it did add a synthetic resistance to the dawn of each subsequent epoch. I'm arguing that, based on history, throwing in the towel and saying that we can't really solve anything further in fundamental physics is not a good idea.

    Society of Physics Students -- UCLA has now given the following writing the thumbs up on their page: THE TRUE AND THE ULTIMATE UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE IS NOW MATHEMATICALLY PROVEN: Gravity/acceleration involves BALANCED inertia/INERTIAL resistance, AS E=mc2 IS F=ma. ACCORDINGLY, the rotation of WHAT IS THE MOON matches it's revolution. This explains why objects fall at the SAME RATE (neglecting air resistance, of course), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. "Mass"/ENERGY IS GRAVITY. E=mc2 IS F=ma. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. INDEED, time DILATION proves that electromagnetism/ENERGY IS GRAVITY; AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. "Mass"/ENERGY IS GRAVITY. Ultimately and truly, time is NECESSARILY possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. This CLEARLY and truly explains c4 from Einstein's equations. THE FOURTH DIMENSION IS THUS CLEAR, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE and completeness go hand in hand. I have mathematically unified physics/physical experience. The stars AND PLANETS are POINTS in the night sky. 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; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It all CLEARLY makes perfect sense. E=mc2 IS F=ma. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 IS F=ma. GREAT !!! IT IS CLEARLY PROVEN. INSTANTANEITY is thus CLEARLY FUNDAMENTAL to what is the FULL and proper understanding of physics/physical experience. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) By Frank DiMeglio

    This was a great video. You explained the incompatibility of quantum mechanics with relativity in a comprehensive way that I've never seen, and it really helped me understand where the conflict is. I'm gathering that one of the main things is that in order to quantize gravity like we do with everything else, you need spacetime to be a continuous field like the other fields, in which those quantized effects can occur properly. But spacetime isn't continuous, it's pixelated. So when gravity has a value somewhere, it would self-interact in ways completely contrary to what's observed in reality.

    What if, at the quantum level, space/time are relatively non-existent? Consider quantum entanglements over large areas. The changes to one happens simultaneously to the other, no matter the distance. This could be explained if space and time were not actually fundamental measures in quantum mechanics. However, if you use the measure of space/time as a unit of energy you can explain, that as things get larger and more massive they can "warp" things that are functions of either or both. Thus a measure of gravity is measure of energy/mass and time and space are functions of both.

    I had a theory a long while ago that dictates gravity is a form of perpetual momentum. Like think of a bullet flying through the space and it keeps going in that one direction. What force particle is being used to carry that bullet through space in that direction? What about centrifugal forces? What particle force is used for that? When thinking about all forces that ties to visible mass, it doesn't make any sense if its tied to properties of their particles.. because all those forces are masses that effects other masses. With the knowledge of quantum physics, you'd think we should have been able to spot gravitons by now as we considered it to be a fundamental force and not something elusive.

    This is something I've been contemplating for quite some time. I am currently in high school and want to be a physicist as an adult. I've been researching quantum mechanics on a semi-regular basis (at least one study session per month). I lack a some of the foundation of these upper level sciences, but that's because I'm only a sophomore 😅. I have recently been looking into some studies on "cell consciousness" and it's correlation to the quantum field. I actually made some of my own hypotheses on different topics based on everything else I know. Just to throw this in the mix, even before I knew it was a thing, I've been contemplating a theory of everything. Before I even made it to middle school science class I was contemplating how the universe worked. It's like a passion. Anyway, in the studies on "cell consciousness" they proposed the quantum field as an intricate brain, so to say, of the cell. You mentioned quantizing gravity. I feel like you can't really explain everything properly unless you quantize everything. Take into account the fields we can quantize and those that we can't. We can quantize fields like the electromagnetic field, as you said, because those fields are governed by the laws of physics proceding the quantum real. Our universe, as we know it at least, exists proceeding the quantum real. Think of the laws of physics more as dimensions. Imagine the things affected by the laws of physics the first dimension, the laws of physics as the second dimension, and quantum mechanics as the third. From both a practical and a mathematical standpoint, we can observe the one dimensional object moving about our two dimensional universe, but we are completely oblivious to the two dimensional plane our one dimensional like universe exists on. I don't mean oblivious in the sense that we are unaware, I mean that we have no direct observation of quantum physics, only observations of the effects of quantum physics. If you were to shoot a bb gun into a room full of objects from a random, unknown point in the room, without observing it directly happening or influencing anything within the room, so long as you knew everything, every single force acting on the object, the exact position of every object beforehand, as well as every possible contributing variable, you could figure out the point that bb started from, as well as the exactly path it took, as well as how much energy it started with, where the energy was distributed, etc. Apply this principal to the laws of physics, and we can observe the effects of physics and even create equations that model everything, but we can't directly observe it. I may be rambling because it's very late but at the time I understood what I meant so this next part might be a bit confusing because it was sort of consciousness focused.. our universe is a consciousness governed by the quantum field. The quantum field is folded and put together in a way that allows every particle to flow from point a to point b on any scale. Because quantum mechanics implies uncertainty, the particles could take any path from point a to point b. Not necessarily on a larger scale, but a smaller scale that fits into a larger path, sort of point a to b to c to d etc to infinity. The only reason that consciousness exists and that universes and dimensions exist is because there is a larger dimension or a higher consciousness to observe it. The quantum field is what "observes" out universe. Our universe is observing infinitely smaller dimensions, consciousnesses, etc, similar to how the quantum field is just one of infinite quantum fields within a higher dimension being observed by whatever would be the quantum field above that universe, a kilo-quantum field? Anyway the cycle would go on infinitely in either direction. I could dive a lot deeper but I need sleep and it's late and this is literally just a KZread comment on an old video that will probably go unnoticed.

    Unless I misunderstood something, when you described the Heisenberg uncertainty principle, it sounded like you were saying that it was a result of the nature of taking measurements, as opposed to something intrinsic to quantum mechanics.

It's just that I thought that was something separate from uncertainty

    It's sort of both. Uncertainty is a fundamental part of waves, even ordinary waves like sound waves. The shorter an impulse of sound is the more frequencies it contains, whereas the more precisely you narrow down the frequency of a sound the longer the signal has to be. You can actually derive the uncertainty principle in QM just from that fact. So the uncertainty is fundamental to the way you measure things (especially because everything is a wave so you can't possibly measure anything without using waves). But technically yes, quantum mechanics says even if you had a magic measuring device that didn't use waves the result would be the same.

    It is fundamental. It also has to do with the nature of measurement. Both are fundamentally the same thing. Quantum mechanics is about fundamental objects exchanging information. Information is carried via the exchange of particles (typically bosons). Nature only "knows" about itself via these interactions, where the information is exchanged. You could call these interactions measurements.

    Of course right out of thought, and yesterday's example. I have a tinted window car. Close it's not easy to see in. At a distance , it's easy to see right through where the light comes through. It has a angle directive on clock work when the sun shines and when it gets dark. So it seems that distance, energy level and location shows some advantage. I look at open clear front window. If it were tinted, idk if I'd have same visual, even if angle and distance were good. At our point, the most recognized transparent visual is earth.

    I'm curious... are we *really* a few equations away from understanding reality? Or rather, is bridging the two theories all that's needed? While I understand that GR and QM explain a lot and that we're missing something in the mix... maybe it's just me framing the situation a certain way in my mind, but I really feel like any math we create/discover to bridge that gap will still leave us with more questions about reality on higher scales. Sure, we might learn more about relatively local things like black holes or quantum gravity but it will fail to answer questions like "what actually happens at the core of the black hole?, "why does anything exist at all?", "is the universe infinite?" Let's say for a moment, we bridged the gap with some math - what kinds of practical issues with that solve? Will humanity rejoice in unison or will there just be a bunch of scientists as excited as a Marvel fanboy at a new movie release? Will that excitement wane after the discovery while the scientists look for the next cool thing?

    I have thought this exact same thing after much time theorizing a fix to the GR-QM problem. The problem seems to reside at this point as, "You don't know, what you do not know" and we will not know what comes next until we are at that point, or simply just discover another problem.

    I thought this also. It depends on what implications the two (gr and qm) have and what the unification of the two may mean to humanity. If quantum gravity was to be solved and one day it will, it would allow us to understand a lot more than we do now. Perhaps give some insight into how the universe began and so forth. It's exciting but would again create more questions depending on what the unification implies.
