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.

@MDBowron 3 года назад

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. Time DILATION ULTIMATELY proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 IS F=ma. The full distance in/of SPACE is thus LINKED and BALANCED with what is the middle distance in/of SPACE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. GREAT !!!!

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.

@armanmkhitaryan27 9 месяцев назад

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.

It takes a paradigm shift to move from one era to the next. In 1904 humanity moved a giant step forward with the publication of Einsteins paper on relativity. Today a paradigm shift is needed to move humanity to the next level, we need the theory of quantum gravity. This is a 4 part video that tries to conceptualise a theory that solves a multitude of major physics problems. Five of these are explained in these 4 videos. For a single theory to solve so many physics problems is unheard of. So please concentrate on the consept and not the delivery. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dFtY8S7TecY.html

@MrRolnicek 5 лет назад

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.

@panstromek 5 лет назад

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

@Ni999 5 лет назад

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 >< close to solving it all. We had Maxwell showing us how to unify electricity and magnetism and we were this >< close to solving it all. A few centuries before Newton had figured out the laws of motion and how to calculate gravitational attraction and we were this >< close to solving it all. A few centuries before that Galileo showed that you could calculate everything in relative terms and that Jupiter had satellites and we were this >< close to solving it all. Going back even further we discovered that earth, air, fire, and water wasn't enough, there was a mysterious fifth element (the quintessence, leading to a pretty handy word we still use today) and we were this >< close to solving it all. 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

@bigsportsman 3 года назад

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.

@Narutendo3 5 лет назад

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.

If there is severe time dilatation very close to the surface of a black holes event horizon, does that mean that the black hole itself is experiencing this time slippage, and if so, will this increase the time it takes for hawking radiation to evaporate the black hole itself?

Yes. That's why the smaller the blackhole gets the faster the rate of 'evaporation'.

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.

holy crap, i damn near jumped out of my seat when you mentioned justin lloyd. i changed my name, and that's my old name. it scared the shit out of me lol

One thing is for sure, Quantum Gravity Theory or General Unified Theory will be at its core a quantum theory. It is almost universally agreed on that everything is quantized. So even space, time and spacetime must be fundamentally quantized.

@thstroyur 5 лет назад

The catch: by 'spacetime', physicists and mathematicians usually mean the Riemann manifold - whereas the space and time coords, those are another affair. Wanna quantize the former? You're welcome to try; wanna quantize the latter? You're welcome to fail ;)

I wonder if the energy of massive objects has a thermal exchange with space. (not in the molecular/particle sense, I mean the thermals of space itself). Might cause a spatial-thermal *suction* of the two massive objects, as the energized space in-between two massive objects expands out in to "cold" space, because energy "likes" to be where energy occupation is low.

not everything is 'quantized' genius

First off, its all relative, so the following proposes that cryptic nonsense must have a scalar value: There is no periodic eigenvalue assigned for singularities. If you equate a real system to cyclical intervals of itself and nothing, the indefinite variable is a periodic constant. Assuming the proof model requires discrete values, are the indice relations conjunctive, or dimensionally simultaneous? Food for thought.

My question comes very late: how much energy-mass does a black hole have distributed in simple rest mass and rotational energy? Rotational energy must be there from simple momentum conservation perspective if the same conservation applies as it does in neutron stars. And what about mergers do the momenta add up cancel or does gravitational wave emission interfere with the rotational energy components of the merging black holes?

Take away all the jargon and you realize mass is a form of energy that warps space time which is known as gravity and if you want to measure gravity, you have to measure the fabric being warped, which is like trying to measure reality, which leads to reality being sucked into a black hole due to the precision of your measurements. Hmmm this universe is strange

@uranus2970 4 года назад

I really think the solution to all of this lies in the understanding of the Higgs-field.

@eliotdayley518 4 года назад

What if Mass warps space And motion warps time That would link the two theories perfectly. Photons being the fastest means that you could only warp time that fast,giving a speed limit and explaining why everything experiences time at the speed of light. To escape gravity you need motion, meaning you have to warp time in the process. Absolute zero would then not experience time however.

@uranus2970 4 года назад

@@eliotdayley518Well if mass is energy what is motion then? The supplier of energy? Is the supplier of energy time itself, is time a byproduct then or is it the process of supplying? I like the way you are thinking though.

@bulentkulkuloglu 4 года назад

Eliot Dayley what if mass warps time, and motion is just an outcome of this process; depending on your point of referance of observation? The reason why mass and time might be related, may have to with they both being in one direction. Unlike space and electromagnetic force (energy) acting in both directions.
