The problem with String Theory is that it isn't "one theory". It's an mathematical attempt to describe all the fundamental particles as 1 dimensional strings. These strings can then vibrate in different ways, corresponding with the fundamental particles and interact accordingly. So on "larger scales", ie the scale of a proton, a string looks just like the fundamental particles we are used to. On the smallest scale it would act as these strings. There are many mathematical ways you could achieve this, over the years they narrowed it down to the consistent ones. Then they managed to mathematically unify those theories under what is now called M Theory. Why all that effort? Well, String Theory describes gravity as a particle, making it a potential unified grand theory. But, here comes the problem, String Theory is "background independent". It only tells us what a graviton would look like, if it would exist at a given energy level. A unified theory would have to do more than that. It would have to relate gravity to the other forces, not just tell us what it looks like.

Ginthian Shield - what is the point in String Theory if it cannot be tested? To me, unfalsifiable hypotheses are basically worthless to science, especially if you cannot apply the scientific method to it, rather its more just a mathematical philosophy. (A little off topic but) Freud is a really good example of this in psychology, where literally all his work is just trying to describe why the mind behaves the way it does, by first observing, and then forming conclusions from that. There is no proper way to prove his work right or wrong so should we actually let it hold any merit until we can find proofs for it?

I once had a dream that Beavis was giving a lecture on Hilbert-space and higher dimensional metrics and in the context of the dream, he was the greatest intellect in the universe, and he was talking about Hilbert-space so as to accomplish something amazing, like backwards time travel so as to undo an event and save the universe. But he still talked like Beavis and laughed in the characteristic way. I like to think that was the true Beavis, that the dumb one in the Beavis and Butthead show was his dumber counterpart in another universe.

Watching this great backlog of content, this one is the best episode yet, imho. This null result really matters and sends many theories into “less likely” categories of possible answers. Also, String Theory again is both ‘safe for now’ and a null result. Imho, being a dedicated hard working fervent string theorist requires a significant level of faith, with so many null results which *could* have been spectacular empirical results otherwise.

What about Hilbert Space, which can theorize there are more dimensions in the macro world? Take a bottle of coke, for instance. You can move it forward-back (z axis), left-right (x axis) and up-down (y axis), but you can also rotate the bottle along its axis (clockwise-counterclockwise), you can also spin it between 0 and 360 degrees in a forward-backwards motion clockwise-counterclockwise, or a left-right motion again clockwise-counterclockwise. That creates 6 dimensions of movement in a macro level. We also use the three dimensions as grid references, for simplicity, but say there are 360 degrees of movement in a flip, what if you expand that circle of movement by a factor of 10, now you have 3600 degrees of movement. It's like you can't get a smallest fraction of a degree, or you could expand that circle endlessly into any size and the degrees will increase based on the order of magnitude. So there are infinite amounts of degrees within an expanded circle or within fractions of a degree.

@Krishna Laxkar the 4D idea is a grid reference point, used to simplify where objects exist in relation to each other. Descartes invented it. But Hilbert came after Descartes, and he proved geometrically that there are more dimensions than the mere grid reference. If every angle of movement is a dimension, then there could be infinite dimensions of movement, as you'll never get the smallest or largest amount of degrees in a circle or sphere. There could also be other dimensions as in other universes in the multiverse like the Turok-Steindhart cyclical model and M-theory.

THE THEORETICAL, TOP DOWN, CLEAR, SIMPLE, AND BALANCED MATHEMATICAL PROOF OF THE FACT THAT E=MC2 IS F=MA OF NECESSITY: Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Very importantly, outer “space” involves full inertia; AND it is fully invisible AND black. NOW, carefully consider what is THE SUN; AS it does (and it must) exist in both time AND SPACE. The stars AND PLANETS are POINTS in the night sky !!! E=MC2 is CLEARLY F=ma ON BALANCE. Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/energy is gravity. "Mass"/ENERGY IS GRAVITY. E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS gravity IS ELECTROMAGNETISM/energy !!!! Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma ON BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity !!! It all CLEARLY makes perfect sense. Carefully consider what is THE MAN who IS standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=MA ON BALANCE !!! (Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE.) Objects fall at the SAME RATE (neglecting air resistance, of course), AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=MA ON BALANCE !!! ACCORDINGLY, the rotation of WHAT IS THE MOON matches it's revolution. The stars AND PLANETS are POINTS in the night sky. The sky is blue, AND THE EARTH is ALSO BLUE !!! Carefully consider what is THE EYE. GREAT. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma IN BALANCE; AS ELECTROMAGNETISM/energy is gravity. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=ma IN BALANCE; AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. BALANCE AND completeness go hand in hand. TIME DILATION ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. This CLEARLY explains the cosmological redshift AND the black hole(s) !!! AGAIN, gravity IS ELECTROMAGNETISM/energy. E=MC2 is CLEARLY F=ma IN BALANCE !!!! Think QUANTUM GRAVITY !!!

I would have expected the gamma rays to arrive significantly later than the gw. Surely in 40Mpc of traveled space there must have been very low density sporadic concentrations of matter or dark matter, leading to a refractive index less than c. Is there such a thing as a refractive index for gravitation waves, identical with that of electromagnetic waves?

I have been listening. The idea that gravitational waves were created with two neutron stars merging and that the intensity and distance traveled would predict the energy you should measure. Then if that measurement is less than expected, that would be evidence for extra dimensions because some energy could have been drained off in an extra dimension. That is clever. That the intensity you measured did not lose any energy seems to indicate that there are no extra dimensions. That is sad but quite clever. Thank you.

Starting to do the same eye rolling. Every test we have done has shown Gravity is an Effect, a measurement of the curvature of SpaceTime and thus not required to be a force or be limited to a minimum size like in Quantum Mechanics. In Relativity the effect of gravity can reach infinity in a singularity thus can be infinitively small. As Mat said gravity not being a force would make many physics people sad. This probably includes him. In other video he covers majority of physics people don't think the Big Bang started with a Singularity anymore. The reason many physics people don't believe in a singularity is they need Gravity to be a force for current work in Quantum Mechanics to reach the truth. They also state Gravity causing Singularities violates Quantum Mechanics where all objects have a minimum size they cannot get smaller than. But actual data keeps showing Relativity is true and thus Singularity possible. The Bias towards Gravity as a Force shows in the current terms used. Dark Matter which actually includes solutions that have no matter involved and thus should be named something like Unexplained Gravitational Effects in Galaxies. Dark Energy with include solutions that don't involve energy when it is better described as, Unexplained reason for observed increasing rate of expansion in the Universe. Sort of understand the short hand as the better description is wordy but it's still a misleading lie in effect. I think there is a bit of a Bias against Deism as you can't rule out Deism if the Big Bang is a singularity does not mean Deism is true eather. Claims that the Big Bang proves there is a God unset some even though the Big Bang does not prove an existence. But an infinite age ever looping Universe to some rules out the action of a God or the Universe having a intelligence. I think the question did something start all of this is still valid then though.

It actually goes in accordance to the experiments, the entire universe would get into a superfluid medium and probably explode into another Big Bang and so on.

I guess I'm a bit slow, but why does gravity have to be a force in the first place? If you've done an episode on why gravity needs to be a force equal to the others, I think I missed it. I thought the higgs boson was supposed to explain gravity, either by being the force carrier or the catalyst for the emerging property of gravity. Higgs gives matter mass, mass compresses/stretches space and we observe it as gravity. Gravity just seems to simply be an emerging property of space being compressed. So confuzzzed :S I'm just glad there are people smart enough on our little ball to slowly figure this out. Keep up the good work :)

In physics, force is basically anything that breaks law of inertia. If object diverges from inertial motion, it is by definition being acted upon by a force. Some forces are just a matter of perspective and go away when you pick the right frame of reference (for example, centrifugal force) and others don't.

For more detailed explanation. Because gravity and other forces are attractive, gravitational energy is negative: one has to do work to separate a gravitational bound system, such as earth and moon. This negative energy can balance the positive energy needed to create a matter, but it's not quiet as simple. The negative gravitational energy of the earth, for example, is less than a billionth of the positive energy of the matter particles the made is made of. A body such as a star will have more negative energy, and the smaller it is(the closer the different parts of it are to each other), the greater the gravitational energy will be. Buy before it can become greater than the positive energy of the matter, the star will collapse to a black hole, and black holes have positive energy. That's why empty space is stable! Bodies such as stars or black holes cannot just appear from nothing. But a whole universe can. =)

Man, that result destroys a whole mess of wild cosmological theories I've heard. The 3+1 universe is certainly easier to wrap one's head around, but now we still have the open questions. I will say that I have a hard time believing gravity is a force like the others are forces. The geometric description is just so elegant. I get that it clashes with quantum mechanics, but I really don't think we're going to find a "graviton". I do have a question though. In Einstein's description of gravity, as I understand it, gravity isn't a force but rather a consequence of inertial movement along a geodesic through curved spacetime. How does this jive with the description of the arrow of time and its relationship with entropy? I never really see gravity and entropy discussed at the same time, even though they're both some of the only concepts that rely on a concept of time, as far as I know. Maybe I'm asking a nonsensical question, but it was a thought I had.

@@ninja250r2008m just to offer a bit of help (a nudge? in approximately the right direction) Entropy is simplest understood as "chaos". Physicists termed it "entropy" in dissertations about Order and Chaos in Systems regarding Thermodynamics, so that's probably the subject you'd find most helpful... Basically, as Time progresses "forward" entropy generally increases... (Simplified Conceptual) Think of your system like building a house. The system will naturally "settle" into a certain order as you build, due to equilibrium. (This is the short-cut explanation for why the solar system and the Milky Way generally resemble discs instead of wonky spheroids)... BUT left to itself, the house will start to corrupt and fall apart eventually... as entropy enters. (Basically, everything systemically put together, falls apart sooner or later.) I'm willing to go out on the limb and quietly suggest Time as three dimensions, being logically the required minimals for interlacing so thoroughly with three-dimensional space to give us the universe as we understand it. Time works everywhere. What's tougher to "wrap your head around" (still baking my noodle years into it) is that we (humans) can't yet measure time the way we can measure space... You can take a ruler or tape-measure that's "theoretically" long enough, and measure anything spacially. It's so many yards, feet, or meters (etc) long, tall, and wide... three spacial dimensions. BUT even a clock or a specialized radiological decay counter doesn't measure Time. It's only feasible (so far) to measure the RESULTS of Time Passing... like the seconds measure "ticks" of gears working inside an old pocket watch or mechanical clock... the "oscillations" of a crystal in a newer digital time-piece... even the particles streaming out of a specific sample of specific purity of radioactive material decaying at a known rate ONLY ever measure the RESULTS of time passing. We can't technologically quantify how FAR in time it will be when the sun next sets a direct beam of light through a certain window in your house (for instance) from exactly the moment I type this period. That doesn't stop it being a dimension, and the same as space, it's more or less just "sitting there" while we pass through it. In fact, it doesn't stop us seeing "results" no matter what "hypothetical vector" we take in passing through it... since we only measure results of that passing. AND super-gravity, from say... ultimately dense objects, can really F*** things up and make them difficult to understand... but I'm still just working on it. I don't think we're going to find "gravitons" either. I have a suspicion (lately) that gravity is kind of a consequence of existing or "expressing" in any material sense. SO whenever particles show mass, they show gravity... just on such an infinitesimal level that we struggle to measure, quantify, or factor it into work. BUT that's just more theory, too. ;o)

@@wellrose17 Okay... bear with me... and I'll try to get it so you understand it. Essentially, a "dimension" is a measureable linear field. In studying dimensions, we use "lines" to represent dimensions... so we have something visual to diagram and measure... and quantify with numbers. So 2D or 2-Dimensional means two linear measureable fields, and we'd represent that as two lines crossing at right angles (usually)... A 2D object then, is a flat plane... like a piece of paper... Somewhere here, it's important to point out that in Physics (especially Astro Physics) we tend to assume everyone knows that dimensions and planes are generally considered "infinite" unless otherwise specified. It doesn't always look that way in diagrams and pictures, but we're "supposed to" put little arrows at the ends of lines to indicate the intention, sort of a symbol of "infinite in that direction"...without having to write it out or draw lines all the way across everything else. It just avoids clutter. BUT assuming most of us already know that, some folks forego the arrows for neatness and move on. 3D or 3-Dimensional means we now include a third line intersecting with the original two, also at a right angle (usually) to both of them, and is conventionally going to indicate space around you in general terms... Normally, the base three dimensions are Height (up and down, vertically), Width (sideways, left and right), and Depth (forward and backward). Those three spacial dimensions can be measured easily with a measuring tape... say in inches, centimeters, miles, kilometers, Astronomical Units, etc... Hope that helps. ;o)

The answer to the gravity dilemma is obvious: God implemented Gravity before he implemented Quantum Mechanics. Gravity is legacy native code being utilized by a managed-code universe that mostly runs on the Quantum Mechanics framework. So-called "dark energy" is just an emergent phenomenon caused by the increasingly-unreliable compatibility between the Quantum Mechanics framework and the Gravity legacy native code every time the framework gets a new security update installed. In the near future the compatibility between Quantum Mechanics and Gravity will break-down completely, and the universe will only be able to run in Administrator Mode -- but God refuses to give anyone besides himself elevated user privileges due to security concerns.

So are extra dimensions totally ruled out or just gravity leakage into other dimensions?
@RedRocket4000

Depends on what type of dimensions are referred to. String theory extra dimensions are not rolled out for the reason he gave in short they are small. Extra Large everywhere dimensions were ruled out. This is for the meaning of dimension referring to things that effect things we observe like Length and Time, things we use to describe what we can observe. Dimensions confusingly is also used to refer to things that are not in normal Space/Time in example Hyperspace ideas or spiritual ideas. This data said nothing about those as this result could not test those ideas.

such gravity leaks are considered impossible on the macroscale, but possible on the microscale... so when we talk about very small particles and their actual real weight are still impossible to detect, and the stability of matter would get weaker as we go smaller... particles would sweep in and out of existence by teleporting through extra-dimensions. There we could detect such chaotic and as predicted in many theories we could prove the existence of these dimensions through the mathematical description of an observed behavior that is like a shadow of extra dimensions in this one and can be detected with much necessary precision as to be scientifically proven.

Could anyone here please explain something about gravity to me: Suppose we have a pair of observers, let's call them Adam and Jamie. Adam is 1 light year away from a pair of positively charged asteroids. The asteroids are at rest, relative to each other, because they are at the separation where their mutual gravitational attraction exactly balances their mutual electric repulsion. Adam is also at rest with respect to them, and the line between Adam and the asteroids' centre of mass is at right angles to the line between the two asteroids. Jamie is in a space ship, heading towards the asteroids at a constant speed of 0.25 C with respect to them and Adam. He too is observing the asteroids and, as he passes Adam, they compare notes. They agree on the charge of the asteroids, and on the distance separating the asteroids from each other. But when Jamie calculates the gravitational force attracting the asteroids together, he disagrees with Adam. In Jamie's frame of reference, the asteroids have additional effective mass due to their kinetic energy. Is the gravitational force of attraction between two objects something that varies depending upon your inertial frame of reference? And, if not, what is the correct frame-independent way to calculate what mass to use to predict the force one object experiences due to the gravitational attraction from another object?

Only the _apparent_ gravitational force of attraction between two objects varies depending upon one's inertial frame of reference. If one can correct to a frame upon which all observers can agree, after corrections, I would call that "the correct frame". If this question springs from something in a physics class, the "correct" answer was most likely already given there. In general, the spectra of light from the asteroids might be used to determine the relative velocity between them and Jamie, if it is not already known. Find that speed and use it to correct the measured mass. Or, if the speed is already known, as was given in this case (probably derived from observations of signals received from Adam), just use that speed directly. And 1/4th of c is not going to produce a large error anyway.

I don't know about the previous answer, but my understanding is that actual mass isn't affected by speed like is commonly understood. When people talk about mass increasing when you approach the speed of light, they're talking about "relativistic mass". Which is really just an aid to understand the changes in momentum/inertia at these speeds. It's best explained in this video: kzitem.info/news/bejne/rYqAx6mXnpiFjYI . Basically gravity isn't affected by relativistic speeds at all.

I believe that this is why Special Relativity applied only to the "special" case of constant velocities (no acceleration) and why Einstein realized that something more. er, lets say "general" was needed for gravity.

The rest mass (also called the intrinsic or invariant mass) doesn't change. But when you are calculating gravitational attraction upon a system of particles, don't you have to look not just at the rest mass of each particle in a system, but also the energy stored in the system? For example, the planet Earth is effectively 2.38 billion tons heavier than its rest mass would be, due to the kinetic energy bound up in it spinning on its axis once per day.

As e.t.’s have explained in nearly-instant remote communications, when, at plus-or-minus light speed, we lens far out around full-universe parameters, we do so via condensed, fraction-of-universe phases where minds feel across extra-dimensions. The giant galaxies from here to M-87, the anchor of the Virgo cluster’s 2000 galaxies, then condense closer, so we can play to a larger crowd there. Although this sounds very out-of-body and distant, in condensed alternate time phases we’re a vast, mixed community of all minds that have ever existed. The diffuse, extra-dimensional character of e.t. neighbors’ minds show precisely such features when they communicate with us. You can’t look at them without sensing this. In other words, being the most evolved of all terrestrials, red dwarf star populations are universe-spanning community that all e.t.’s blend into. Imagine being in many-minds community without reference to such neighbors. It would be like hiding in some past time without real, universe halo capabilities. Universe halo astrophysics are the most evolved and capable, so we should consider them in parallel to all that we do. They’re universe-spanning, extra-dimensional shortcuts that neatly cut out all of the crap that we won’t want to waste time on. After remote, many-minds communications with e.t.’s, we become accustomed to, and then skilled in communicating via universe-spanning halo. So, we alternate between universe-spanning halo and the condensed contours of the entire, known universe. It’s very extra-dimensional, as is all life in many-minds consciousness.

Question: Could the possible reason for the Zero extra dimensions be due to the fact that our measurements and the location of the event lie at the same point (or very close) in that 4th dimension? I.e. if us and the merger happen at the same point in the 4th dimension, the energy dissipation to that dimension would be negligible and therefore might look like no extra dimensions to us (as 3+1 dimensional observer).

Well the effects of that extra dimension would have also shown up relating to the amount the universe is expanding between us and the event so they couldn't have been too close, ie because there is hubble constant expansion and the event happened in another galaxy. This is assuming the theory being tested was true. I'm no expert though

I don't think so. The decrease of intensity is proportional to 1/D^k, with D being the distance to the source and k being the number of dimensions wherein the impulse is spreading out. Since the merger happened in a galaxy far, far away (140 million light-years to be precise), that decrease in intensity should be well measurable, regardless of how long it took the impulse to cover that distance, as its speed does not affect how it spreads out.

The only problem is that the turing machine itself would have to be included within the "entire universe" and thus exist on the one dimensional tape of infinite length that feeds into the turing machine that exists on the one dimensional tape of infinite length..... and so on. Material objects do not lend themselves well to being good analogies for infinity. The only thing which lends itself well to describing something which is infinite is that thing which is actually infinite. Ipso facto, reality is not bound by material limitations.

One observation: "infinity" is a null concept. I admit it is a convenient placeholder for "we just don't know". Example: the galaxy is not infinite, though it seemed so until our knowledge encompassed extra-galactic objects (other galaxies). The Universe must logically be finite, though it's limits are beyond our current ability to quantify. It may take us centuries to identify its many components and begin to understand how they work. 😘

@@rjonboy7608 infinity is absolutely not a null concept. Where did you get such an idea? The entirety of mathematics rests upon infinity. The entirety of science depends on mathematics. Black holes are the closest thing in the material cosmos that comes to infinity. The study of black holes is all about infinity. Not even basic calculus would work without infinity. The infinitesimal entity and the absolute infinite are inextricably linked and fundamental to the basis of existence. There is no such thing as a physical Turing machine because it depends on infinity. Similarly, the real circle and pi are infinite, but your cardboard cutout of a circle is not actually the real circle. The real circle is not a material object. And so similarly, consciousness is not a material object. This is a logical fact. The infinite cannot be arbitrarily disregarded just because we are habitually accustomed to thinking only in terms of a simplistic Lego brick view of reality. Reality is not a Lego brick finite construct. There is a necessity for a bit of mind expansion for most people.
