I've been a Champion Of String theory for as long as I can remember, String theory is so Beautiful, It's like a work of art, But There is a line that must be distinguished, Which Principal is most important, Truth or Beauty. Everyday More and More physicists are parting ways with conventional String theory as Quantum Physics continues to Gain More Ground, I am a Fan of quantum physics, Of course, But, As we learn more of the truth, We have to let go of certain things, Not just because they are untrue, But, Because to continue to devote energy to this thing is nothing but a waste of a good education. String theory is all but completely disproven, And it happened as early as 1919, Not long after Einstein Published his theory of general relativity, Another Likeminded individual named Theodore Kaluza Was playing with the concept of Relativity within a five-dimensional space, "Because, Why not, it's how we do..." When he discovered That in a five-dimensional space you can separate the Einstien relativity equation into a fourth-dimensional component That looks a lot like General relativity only without the famous Einstien Equation. Theodore Kaluza Basically, What Kaluza Had done, Was Unify a lot of dimensional theory by proving many of them, were trying to Describe the Exact same principles of energy to matter conversion and had arrived at the same or similar results using drastically different unified field theories. The Nail in the coffin is Oddly enough, Kaluza's Math Looked an awful lot like Maxwells Equations for Electro-Magnetism. It appears That To Us, trapped in this fourth dimensional space-time, That Gravity would appear to us as Electromagnetism, Because We could not fully perceive it for what it was, Being that it's a higher dimensional space than our own space-time. Stay with me here, So In 1920, Oskar Kline Solved this issue by proposing That Electromagnetism could react within the strong and weak forces of Gravity if you account for Extra dimensions spaces within our own space-time, Oskar Kline To give this in a short Nutshell. You See, String Theory is Incorrect because These other Dimensions, They are not What people Want them to be, They are not some other universe with Great space within them. This Fifth dimension and higher dimensions Are not spaces we could ever have much use for because These Dimensions are Very tiny and compacted into the smallest particles in the universe. They interact with us only on some Quantum level so Microscopic yet because there are so many particles, It's like a quantum particle storm of higher dimensional space really. Here is an example, Imagine Strings, In String theory those strings, are the tiniest possible physical particle They would Vibrate and Cause those waves at different wavelengths. In Kline's Theory, Strings are not strings, They are Loops and they, These loops are not fundamentally strings, And function differently than String theory suggests, in fact, String theory proposes that these other dimensions are not microscopic, That they are as large a space as the universe we live in, That's just not True, These higher dimensions are Tiny, Microscopic even. This Is all Still Theoretical Physics, But At least Theoretically, String theory is losing more and more steam, As more modern thinking and mathematical approaches seem to ebb away at this Titanic Theory, A Little more Every day.
