String Theory Explained - What is The True Nature of Reality?

Is String Theory the final solution for all of physic’s questions or an overhyped dead end?

      @THE VIOLINIST so you only believe in the four verifiable dimensions? That's fine, that's the same viewpoint. The big bang hasn't been verified either. We're simply putting together the best picture we have so far and to get more of that picture we start with hypothesis

      @SuperDiabeetus Explaining why String theory requires 10 dimensions instead of 4 (the number of verifiable dimensions, unless you include probability, which is arguable) is, essentially, an actual explanation of string theory, which was what this video promised to do; how a point is used in Quantum theory is easily explained and visualised, whereas the string in String theory never has been in the 30 or more years that I have looked for an explanation If you ever do find one, please post a link...

    Far more believable than a bunch of spinning balls staying in orbit by gravity but yet always moving apart. SPACE IS FAKE. Believing in spinning balls is just that a belief with no facts to back it up

    What if is not *strings*, but *spirals*? Energy filling the most surface with the least waste of resources, the same way spirals and fractals are formed naturally in the cosmos, they also appear in how we, as intelligent beings, transmit energy through information: music, art, stories... (think the golden ratio, musical notes, the hero journey), is like the same energy formed in the big bang is always forming spirals because that's the easiest way for energy to flow (in other words, the path of least resistence) Does any of that makes sense?

    Did u guys ever think about why we feel so good, refreshing, weird, sometimes mysterious, and that we want to touch those stars, to reach there? Its because those stars are really our ancestors (well... Not actually if u consider the facts), we are made up of them. You know how? Well, the stars that you see in the sky are maybe not alive now, and when they(giant stars) dies by Supernovae, they releases all the partices present in them in the space, which then combines at different regions of the universe making different stuff, like other stars, galaxies, human and all. Whatever we are made of today are from the remnant of those stars billions of years ago, and maybe the star that you see at night, those are very old (might be dead by now) but we still see them as the light from those stars left them billions or millions of year ago.. Technically, we look at past when we stare at the night sky. And as Carl Sagan said: "We are made up of Starstuff"
