UNDERSTANDING TIME AND TIME DILATION (ON BALANCE), AS E=MC2 IS CLEARLY F=MA; AS ELECTROMAGNETISM/energy is gravity. Let's talk about what Einstein curiously didn't talk about, at least publicly. Let's talk about TIME along with the VISUAL experience of the man who actually IS in outer "space", AS this is to be DIRECTLY compared with the BALANCED BODILY/VISUAL experience of the man who IS standing on what is THE EARTH/ground (in and WITH TIME). In the first case, there is no feeling of gravity. There isn't relational motion (or mobility); AND, basically, there is INSTANTANEOUS death. So, THEN carefully and FULLY consider what is THE SUN (as it IS, AND as it must be/REMAIN). Great !!! INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience. Indeed, the stars AND PLANETS are POINTS in the night sky. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) For the man who IS actually IN outer "space", basically, obviously, and fundamentally, there is NO TIME. Excellent. Again, WITH this INSTANTANEOUS VISUAL EXPERIENCE, WITH the RELATIONAL consideration of what is THE SUN, what is THE EYE, AND what are the POINTS in the night sky, there is NO TIME (basically, obviously, and FUNDAMENTALLY). Great. Time DILATION ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity is ELECTROMAGNETISM/energy. Therefore, BALANCED inertia/INERTIAL RESISTANCE is fundamental. E=MC2 is CLEARLY F=ma ON BALANCE !!! GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity. ("Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/energy is gravity.) Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS clearly F=ma IN BALANCE; AS ELECTROMAGNETISM/energy is gravity. Accordingly, the rotation of WHAT IS THE MOON matches it's revolution. Time is NECESSARILY possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma ON BALANCE. Consider what is THE MAN who IS standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is gravity. Our energy density is the same as water. Consider what is BALANCED BODILY/VISUAL EXPERIENCE. (THE EYE is the body ON BALANCE.) The sky is BLUE, AND what is THE EARTH is ALSO BLUE. Gravity is ELECTROMAGNETISM/energy. E=MC2 is CLEARLY proven to be F=ma ON BALANCE. THEREFORE, objects AND MEN fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma. E=MC2 is CLEARLY proven to be F=ma ON BALANCE. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. Great !!! Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=MC2 IS F=ma ON BALANCE; AS TIME DILATION ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. This explains the PERPETUAL motion of WHAT IS THE EARTH/ground on balance, AS ELECTROMAGNETISM/energy is gravity; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=MC2 IS F=ma ON BALANCE. SO, I have mathematically unified physics/physical experience; AS I have mathematically proven why and how the rotation of WHAT IS THE MOON matches it's revolution AS WELL !!!! CAREFULLY CONSIDER WHAT IS THE SUN !! GREAT. E=MC2 is CLEARLY proven to be F=ma ON BALANCE, AS ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. The stars AND PLANETS are POINTS in the night sky. NOW, consider what is the speed of light (c). Accordingly, I have explained why the planets move away very, very, very slightly in comparison to what is THE SUN. It all CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand. Stellar clustering ALSO proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS clearly F=ma ON BALANCE. Indeed, HALF of the galaxies are "dead" or inert. Gravity is ELECTROMAGNETISM/energy on balance. By Frank DiMeglio

According to Physicist Lee Smolin, one of the main issues with String Theory is that it is background dependent, not to mention that it is untestable. That makes it more of a philosophical exercise than anything else. Thank-you for making these topics accessible to anyone with the interest. Love this channel!

@shawnmunck7412

Жыл бұрын

Untestable? I think your a bit off on your info if you think that. I'll try to explain as best as I can what I mean. String Theory is a physical science based on vibration and energy, yes? Guess we all knew that stepping into watching a video like this to begin with right, but what most don't take into consideration, is the fact that Einstein is one of the founding fathers of String Theory. E=MC2 is something he came up with that hints at his later theories on special relativity in 1904. Fast forward a few decades to the 1920s and the manuscript used to calculate black holes and wormholes(known as Einstein-Rosen bridges) deal with how gravity works. This gravitational science(before it got recognised as string theory) dealt with how to observe gravity and vibration and what kind of energy is found within such structures. It was not until 2019 that Black holes were scientifically proven to have the same measurements as what was penned down 100 years earlier, based solely on the math. 1 and 1 will always be 2 mathematically and so the measure meants derived on what string theory is and how it operates, including simulations on what these strings look like are all mathematically accurate. String Theory is all math. And the math is never wrong. Its just taking time for us to catch up with the empirical evidence. Time and time again we deny simple truths such as this. All you gotta do is take a look at flat earthers to see just how far people will go to distort the truth and create a 'truth' people will believe in. Cancel culture is not a new age thing. Its been apart of humanity's history for as long as there were people to live it. So to sum up everything, all I will do is leave this open question out for you about something seemingly unrelated to quantum fields, that of consciousness itself. How can you prove consciousness exists? We see the effects of it. We live and experience it. But how can you prove it with tests? Where is it located in us? This is as untestable as String Theory is. Infact, some might say that consciousness is the body's way of using quantum fields on an everyday basis. So just because you cant test for something specifically dont mean it aint real. We just havent created the tests for it yet. 🤷‍♂️

@@shawnmunck7412 You misunderstand the OP. The problem with string theory is that it not only can it explain everything (a good thing and necessary for a theory of everything), but it can be used to explain ANYTHING. If it can be made to explain literally anything, then you can't make a prediction that the theory can fail. You can't say "if the theory is true, when we do X then Y will happen, but if it's false then not-Y will happen instead." There is no "not-Y" condition for string theory, or all the "not-Y" conditions require experiments that are physically impossible to perform. The prices of falsifying hypothesis is the core of how science works, so if string theory can't be falsified then it isn't a scientific theory. String Theory is essentially at the point where it's a fancy way of saying "God did it." Any question you ask there is a perfect counter - "Why don't we see God then? Because he's invisible." "Well why don't we just ask God and if he's real he can tell us? Oh God didn't talk to people." "Why would God arrange things so it looks like he doesn't exist? Oh it's because he thinks it's funny." There's no actual predictive power in a theory like that, to the point that even if it were actually true you'd never be able to prove it and it would be completely useless besides.

No this is completely wrong. Roughly speaking, we understand quantum theories best in the “weak coupling limit,” that is, when quantum effects are small. When they are large, in general, the theories become extremely complicated and we can’t understand them well. However, string theory has an astonishing property called S-duality. When quantum effects become big in one theory, it’s exactly equivalent to another string theory in which quantum effects are becoming small. M-theory is an 11 dimensional theory that reduces to all of the other theories in various limits. There is a tremendous amount of mathematical evidence that says M-theory exists, although it’s exact nature is not yet known.

That is not so testable nor observable unfortunately, actually the fact that it is not testable with our current technology is the argument used by String Theorists to explain why the various predictions of String Theory have not been observed - we have not produced high enough energies. It does not provide any answer for how much energy is required to produce the observation, so we cannot even theorize a test/ larger particle collider that could guarantee observations or disprove the theory. CERN could make their 20 billion dollar super collider, and if we still haven't seen the higher harmonics, the partner particles, ..., they will once again say we just haven't reached high enough energies - it cannot be proven false that way

For this reason, I do not consider string theory to be a scientific theory. Economics is another example of a science which I feel isn't justified for its use of very complicated math, because this math far too often fails to model reality.

To be fair, I really don't know much about either of these, so perhaps I'm not qualified to give a fair judgment of them. In any case, being a longterm student of math and physics, I love both of these fields. I appreciate the beauty of mathematics, both pure and applied, and I'm in awe of the beauty of math as applied to physics, although I still think that string theory is premature, whether or not it's accurate.

@@dcterr1 2008 was essentially the fault of President Bill Clinton repealing the Glass-Steagall act that was brought in after the 1929 Stock Market crash. It enabled these big investment banks like Goldman Sachs and Lehman Bros. to provide imprudent backing to mortgage providers like Fannie Mae & Freddie Mac, who then made reckless mortgage loans to high risk, literally, crackhead homeowners - who would routinely default on their payments, put the keys through the letterbox and skip to the next state to do it again. A mechanism existed between regular main street banks to help failing banks through a network of support, but this was over leveraged. Goldman Sachs packaged bad debt with good long term payoffs and sold it to the Icelandic economy, which I think was hit particularly hard by the US malpractice. I think there was one arrest. President Obama was one week in office and the Secretary for the Treasury was on his knees begging him to bail out the US economy, or risk complete collapse. That was the wrong call. Obama shouldn't have bailed out the banks that were too big to fail. He should have let Goldman Sachs and Lehman Bros. go to the wall, and underwritten the first $100,000 of all main street banks, and nationalised Fannie Mac & Freddie Mac. This political-economic perspective is based on a conversation with the author of _Fannie Mae and Freddie Mac: Turning the American Dream into a Nightmare_ as back around then I was responsible for feeding her Persian cats. Any talk of being misled by economic models is bunk.

That at one time we're considered silly. Even Einstein thought that quantum entanglement was "spooky action at a distance" yet I believe it has been proven that particles that are entangled, like two photons "born" at the same time. can mimic eachothers spin in an instant across any distance. Making faster than light communication possible. Which was and has been considered impossible for quite a while.

I suspect that the reason there is so much enthusiasm about string theory being potentially "wrong" is that many people feel too many resources (or at least too many physicists) are being (or have been) engaged in exploring it. The universe may not owe us easily verifiable or falsifiable laws, but do we not perhaps owe ourselves to spend less resources on theories that prove this hard to verify? This is not to say we shouldn't be exploring string theory, but how many people does it take? How many people did it take to turn Weyls wrong symmetry into something useful? I think the reason string theory is so controversial is not because of its right or wrongness, but because of the large amount of resources being poured into it and therefore not into other competing theories in recent years.

Your channel is really interesting, and I enjoy watching all your videos, including those about theoretical physics, although I'm an astrochemist who doesn't understand all the details of these complicated theories. I just wanted to point out a small mistake at the end of your video when you answer people's questions. DNA is indeed a right-handed helix, but not because it's made of right-handed chiral amino acids. The structural chemical backbone of DNA and RNA is made of a chain of right-handed (D) sugar units, 2-deoxyribose for DNA and ribose for RNA (hence their names deoxyribonucleic acid and ribonucleic acid), themselves attached to a phosphoric acid and nucleic acids (A, T, G, C for DNA and A, U, G, C for RNA). Amino acids are the building blocks of proteins, and in terrestrial living organisms, all the amino acids used to make proteins are left-handed (L).

You explained it way better than I could, but here are some extra fun facts: Left handed DNA also exists (although rare in nature) and is called Z-DNA! It is very strange and zig zagged and is thought to contribute to genomic instability (high rates of mutation). And L-amino acids are why proteins form exclusively right handed alpha helices!

This video was really good for the me that started watching it. There is still plenty of stuff in it that I don't understand, but it was close enough to what I do understand and I think there's now at least one more thing I feel like I understand enough to describe it to someone else.

You discuss the string theory with a great clarity and an obvious depth of knowledge. I have read many books about the string and M theories, but they were full of convoluted descriptions, hard to port outside their environment. For the "beauty Vs truth" debate, I choose truth without further thinking. In a further step of my logic process, I do believe that the debate in itself - it constitute a wrong metric. Science research require inspiration, like any other creative process; but I use my inspiration when I make initial hypoteses, not when choosing which of these hypotheses are correct. Beauty Vs truth criteria is an epistemological mistake. Thank you for your video, highly appreciated.

I have been following these meta theories, string theory, m-brane theory, quantum loop gravity, relativity, variations of quantum mechanics for decades, and I have concluded that the fundamental error being made is the attempt to derive a coherent mathematically defined space-time manifold which has the properties that all of the known physics energy interactions, and conceptualized forces can be mapped to the characteristics inherent to the space - time manifold. I do not believe any such manifold and system of mathematics will every be found which encompases all known physics. First, space time is not a thing in the sense of being a first order phenomenological object. Matter - energy creates space time as a secondary dependent condition analogous to the way an obstruction of light creates a shadow. If there is no light and no obstructing object, then there is no shadow. If there is no energy and matter in the universe then there is no space and no time. Prior to the big bang there was no space and there was no time. Remove all matter / energy from the universe and there will be no space and no time in the universe. So it is a mistake to imagine space time (apart from energy / matter) as a first order phenomenological object which can have qualities corresponding to mathematical constrains which in turn create the laws and principles of physics. Instead, all of the laws and phenomena of physics are aspects of all of the forms and variations of energy / matter itself. And the second conceptual mistake is to attempt to search for or define an overarching mathematical frame work that consistently accounts for all of the variations and appearances of physical laws as if they are a single linked entity. There is no reason to conclude that every manifest physical principle is linked to every other physical principle at some fundamentally deep level. This is just an unproven assumption, there are alternatives, physical laws can be a set of constraints without binding logical or analogues cross relationships. For example, there is no fundamental all encompassing proven rule that says 'spin' and momentum in a sub atomic particle has to have the same behaviour as spin or momentum in macro classical physics. The universe and its laws do not have to all be manifestations of some inter-related cross dependent analog functions, alternatively it can be a set of conditionally dependent constraints which track to limited mathematically expressible laws, operating independently within those constraints and limits.

Everyone seems upset about explaining gravity in trying to have the full understanding of these systems and how they should relate. Gravity seems to totally to revolve around mass and the electromagnetic properties that mass inherently has.

Why don't you submit your thoughts to a peer reviewed journal and get a Nobel prize? Why are you wasting your time going into depth on a theoretical physics idea in a youtube comment section?

@@drhexagonapus because the fundamental problem is group think, especially among academics. So what ever I say its going to be ignored and ridiculed if it not the standard group think BS, - just as you are attempting to do. I dropped out of a physics major decades ago just for this reason. If my comment bothers you by my posting it here on KZread, my suggestion is that you could find something else to think about.

@@lordkizzle No, I do not think that is the case at all. I have been studying this topic for decades. I learn a lot from others, but I maintain my ability to think and decide for myself, and early on I understood that there is a lot of group think, a lot of agreeing to the academic consensus or else. That is agree with the academic consensus or you are not one of us, AND if you do not agree, then we do not respect your contrary views. But in reality there are many important open questions in physics, there are commonly accepted working hypothesis which are total and obvious BS and are completely ad hoc with no empirical basis, like 'dark matter' for example. So no one owns these ideas or other ideas beyond how people use them to identify in and out crowds, or how to usefully use them to help explain, understand the topic. I do not expect anyone to develop 'my ideas' I do not own any ideas, I am not invested in them in the sense of my identity or employment, or social standing.

Your videos are awesome! It helps me gain more of an understanding on these subjects.

Really good presentation with incredible visuals - reminds me of my 2 metre wide cane and string topological model for speech day which fell down the night before

To choose beauty over truth is the choice of a fool, because in the truth lies something far more beautiful than we could have ever imagined

I was discussing with a friend of mine another day about how Kaluza-Klein where SO close to actually formulating gauge theory electromagnetism hahaha Like, bear with me: in gauge theory we basically look at the fibre bundle made by the base manifold (space-time) and the associated Lie group, in the case of electromagnetism the group is U(1), which, guess what, is precisely a circle, so you have space-time with this extra circular dimension, and the Faraday Tensor turns out to be the curvature of the gauge, so yeah, if they had realised that this extra circular dimension was not a simple extra spatial dimension but actually a Lie group on a fibre bundle, they would have formulated gauge theory quite early xD

Great explanation of Kaluza-Klein. Not so great description of what dualism is, though. Dualism allows you to switch between two sets of words in a statement and still get a true statement. For example: A rectangle has two lengths and one angle. A rhombus has two angles and one length.The dualism between angle and length makes a rectangle the dual of a rhombus. A square has one length and one angle, so it is trivially its own dual. A parallelogram has two lengths and two angles, so it is its own dual as well. A trapezoid has three lengths and two angles so it is the dual of a kite, which has three angles and two lengths.

His explanation makes a lot more sense than yours xD Edit: I'm pretty sure your explanation is just bogus anyway. Duality is being able to describe the *same thing* with two, seemingly contradictory, explanations. You're describing different things with different explanations....

No, that is not what dualism is. An example of a duality is “possibility and necessity”. If something is NOT possible to be, then it is necessarily NOT, and if it is NOT necessary, then it is possibly NOT. They are dual with respect to negation. Symbolically, it is easier to grasp. If I represent that something is possible with P, that something is necessary with N, and negation with /, then I can write /P = N/, /N = P/. This sort of symmetry that happens when you relate the two things via negation is an example of the definition of duality. Another duality is in obligation and permission. NOT permitted to do X = obligated NOT to do X. NOT obligated to do X = permitted NOT to do X. Obligation and permission are dual with respect to negation. You can express something about one thing using the other thing, and vice versa, because of the way they are related by negation.

I love this channel. I've watched so many videos since finding it a few weeks ago. One video I would love to see would be on one of Bohm's takes on quantum menchanics, Implicate and Explicate Order: en.wikipedia.org/wiki/Implicate_and_explicate_order It's a complex, dense, and interesting topic and I would love to see if it could be broken down as simply as you guys are able to. Can't wait for the next episode!

13:17 If there are around 10^500 different Calabi-Yao geometries to choose from, and physicists and mathematicians around the world work feverishly to eliminate all the ones that are not correct, and they manage to eliminate 1 geometry per second, it would only take about 10^493 years to find which geometry is the correct one.

For some reason, t-duality just reminds me of myelination and axon diameter with regards to voltage gated channels. Seems like the same concept and not weird to me at all haha. But I’m a neuroscientist so my brain probably just wants to translate everything into neuron stuff. 😂😂
