The only reason I ever got into theoretical physics was because of Brian Greene. And it was very random, too. Back in 2000, I was home, channel surfing at like 1am and I just happened to settle on a UHF channel and it was Brian Greene, giving a talk at a bookstore while promoting his book, The Elegant Universe. He started talking about string theory and I was hooked ever since lol.

I recently discovered Brian Greene after a random KZbin tangent. I was totally onboard with his presentation until the 13 minute mark. This is where I think his rhetoric completely falls apart. His argument is cyclical, not actually answering the question at hand but instead relying on his own definition to prove its validity... Completely meaningless. It's a real pity too, since I was so engrossed in the rest of his presentations. Unfortunately, I don't think this one holds any merit. As a theoretical physicists, what do you think?

Unfortunately, this entire presentation is incorrect but it's not his fault. He (as well as all other physicists today) have been taught the same incorrect information their entire life and therefore believe it to be true. Therefore, the reason these principles of atomism and string theory work is bc they are the logical conclusion to the previously known and accepted theories. Our Universe and its working will never be explained using Einsteinian Physics and the idea that everything is a particle and they create "waves". It is flat out wrong. Very very few people will even accept this as a possibility let alone the truth. I don't expect this to take hold anytime soon.

[@isatousarr7044]

String theory proposes that fundamental particles are not point-like but rather one-dimensional "strings" vibrating at different frequencies. It aims to unify all fundamental forces of nature: gravity, electromagnetism, and the nuclear forces into a single framework. The theory often involves additional dimensions beyond the familiar three and incorporates concepts like supersymmetry. While promising, string theory faces challenges due to its complexity and the difficulty of testing its predictions experimentally.

To me, it makes sense that dimensions exist that don’t interact noticeably with the ones we experience. After all, think of all the cell phone signals, wi-fi, Bluetooth, tv transmissions, etc. that surround us, yet we are oblivious to them. We have X-rays that go right through our soft tissue without being felt by us. Infrared signals in our remote controls. All these are constantly in our environment and operate in the dimensions we know about (the electromagnetic spectrum), but are only accessible with the aid of specially built detectors which extend our ability to detect parts of the spectrum our bodies have not been adapted to sense. The problem, of course, is that at our scale, there are size limits to what our specially built detectors can sense both in small scale, as well as large scale (e. g., the observable universe). It’s truly amazing the rate of change in our understanding of the universe in the last hundred plus years. Who knows what mysteries will be solved in the coming years? Fascinating!

I am currently obsessed with String Theory bc since around the time Covid began I've been having "crazy" ideas, thoughts and experiences about existence, time travel, afterlife, paranormal, multiverses, space, time, perspective, brain and memory functions, disease, blood types, predispositions, etc.. and after learning the basics of this theory I feel like it may explain it all in one way or another. My family has even sent me to rehab after 3 clean drug tests bc I opened up about the thoughts I'd been having.. but when I went there I found so many of my peers have had similar experiences and thoughts during this pandemic which has led to a higher than normal rate of worldwide death. I was raised pentecostal so spirits and the supernatural and religion have always been important in my life. I have said many times that God decided to bypass the apocalyptic Christian Revelation, and instead, disperse life across multiverses and eventually we'll all be able to not only rest, but live and store memories forever (exist immortally), in peace.

It should change. We have to include modern theories as well. Nothing about Relativity is known till 12th.

[@hasanmahmood2321]

This is far too advanced to have in a school syllabus, the level of Maths required is so advanced that even most Physics degree courses don't include String Theory. If you want to study it you'd have to do a masters in Maths, and even then you probably wouldn't touch on Superstrings. To do that you'd have to go to PhD level. I suppose it might be good to introduce these ideas at a non technical level in schools though, like this talk.

[@vikrantchaudhary4946]

The level of Mathematics required is available in our 11th and 12th (Matrices, partial differentiation, and many other topics). I studied few General relativity equations in 12th from Physics Olympiad books. And I was able to solve many questions related to objects at very high speed. At least a glimpse can be provided to raise interest. We do have Polymers, Crystal Field Theory in our Syllabus.

[@hasanmahmood2321]

vikrant chaudhary It's a lot more than just matrices and PDEs, those are just the basic tools. On the mathematical side, you need to have a high understanding of lagrangian and Hamiltonian formalism and how to quantize a classical action/Lagrangian. You also need a lot of group theory and geometry knowledge, as Dr.Greene alluded to in the video when he mentioned Calabi Yau Manifolds. On the physics side, you need to be very competent with quantum mechanics and quantum field theory, as well as electrodynamics and the standard model. General Relativity helps a lot as well. I haven't actually studied string theory myself yet by the way, but I've read into it and I've looked into what you need to know to study it formally. Personally, I've only studied as far as QM and GR, so I've got a fair way to go yet. But yes I agree that a glimpse would be a good idea just to spark interest.

[@vikrantchaudhary4946]

Yeah, I am not saying to make a scientist out of a High school kid. But telling him about Lorentz equation isn't much. I did not need the first 5 lines you typed. My idea was just in your last line. Did you study all those at once? You had a start somewhere and that's what my argument was. Was electro dynamics part of high school syllabus 130 years ago? but it is now. Syllabus change with time and well-educated people like you are the reason for the development of Humankind. Thank you

C=Distance/Time According to this equation, When distance increases, speed of light(C) will change but speed of light(C) needs to be constant. So in order to make speed of light constant, time has to change too with distance D. So time(T) will expand or delayed with increase in Distance to make C constant.This phenomenon where delayed time or expanded time occurs is known by the name Time Dilation.This theory is possible only if we think speed of light is constant(found by Maxwell.)

Why the extras dimensions need to be small ? maybe they are too large to see. Just like a 2D creature has no idea of the 3rd dimension but in reality its all around him, similarly maybe the extra dimensions are everywhere but being 3D creatures, we can not see them. there is no sense in saying that a dimension is 'small' or 'large'. dimensions does not have a size themselves. dimensions are the directions towards which we measure size.

[@Gindaman999]

+Marv3Lthe1 Maybe, maybe, you might be right. But theoretical physicists make predictions and create philosophical extentions based on the physics proven and observed in reality. You might be right, but nothing right now leads scientists to feel the urgency to look in that perspective. But there are underlying structures describing quarks behavior which leads them to believe quarks can embody some form energy we cannot easily detect.

[@thehmongzelda]

Easy. It's small because it's the small stuff that we are sending to those other dimensions with the cern collider thing. If big ass shit was to be disappearing then the other dimensions would be big.

[@JeanPineau44]

+Ya Lee Indeed gentleman, quite quite

[@Fleato]

Marv3Lthe1 you're right dimensions have no relative size. everything from a quartz to the entire universe could be considered as 1 measurement of a dimension and every thing inbetween. however the problem with dimension is no dimension can be proven, yet we know they exist. such as the 3dimensions of space, we can't prove any direction but we know it's there, and time cannot be proven or quantified but we know relatively our own standard of time, choice cannot be proven either as once we say "yes" we cannot prove the out come of " no" when answering a question and so on. so dimensions cannot be proven yet can be as big or small as anything and everything.

[@notactuallyme4822]

I think of all dimensions as a bunch of organic fractals. Whether zooming in or out, size is all relative and can only *be* relative to the objects within them(the respective dimensions). Much like the end of MIB only instead of existing in marbles, we're in something else's particles, being waved off by their appendages whilst fanning the air.
