String theory is a purported theory of everything that physicists hope will one day explain … everything.

Quite a report and interesting 2:46 video from Paul Sutter. The report made some interesting comments.
"With further mathematical insight, it was found that the extra six spatial dimensions needed in string theory have to be wrapped up in a particular set of configurations, known as Calabi-Yao manifolds after two prominent physicists. But there isn't one unique manifold that's allowed by sting theory. There's around 10^200,000. It turns out that when you need six dimensions to curl up on themselves, and give them almost any possible way to do it, it … adds up. That's a lot of different ways to wrap those extra dimensions in on themselves. And each possible configuration will affect the ways the strings inside them vibrate. Since the ways that strings vibrate determine how they behave up here in the macroscopic world, each choice of manifold leads to a distinct universe with its own set of physics. So only one manifold can give rise to the world as we experience it
. But which one? Unfortunately, string theory can't give us an answer, at least not yet. The trouble is that string theory isn't done — we only have various approximation methods that we hope get close to the real thing, but right now we have no idea how right we are. So we have no mathematical technology for following the chain, from specific manifold to specific string vibration to the physics of the universe. The response from string theorists is something called the Landscape, a multiverse of all possible universes predicted by the various manifolds, with our universe as just one point among many. And that's where string theory sits today, somewhere on the Landscape."
The math of string theory leads to a *multiverse*. I have other reports in cosmology that shows the multiverse contains 1E+500 or more different universes and now I see 1E+200,000 Calabi-Yao manifolds in the report. The video indicated problems continue with quantum gravity used in quantum mechanics called loop quantum gravity with gravitons. Apparently each universe that evolves in string theory can have its own unique set of physicals laws or likely no natural laws operating.
In astronomy I enjoy using my telescopes to observer Jupiter and the Galilean moons. Well predicted events take place at Jupiter like Io eclipses and transits. In the heliocentric solar system, Kepler's laws (elliptical orbits), Newton gravity, laws of motion, predict those events accurately and are verifiable using telescopes. It seems someone in a multiverse could live in a geocentric solar system then, but verifying this looks difficult
. Presently, astronomical observations showing the multiverse is true like the debate between geocentric astronomy vs. heliocentric astronomy where the geocentric teachers were falsified, is a work in progress.
So here is my bottom line. The heliocentric solar system is more verifiable than the multiverse with 1E+500 or more different universes and now I read about 1E+200,000 Calabi-Yao manifolds. Very interesting math and physics developed to explain the origin of our universe. The model(s) seem to have a long way to go before they meet the science testing standards used in the geocentric vs. heliocentric debate in astronomy. I enjoyed this report because I can see more details then past reports I read about string theory. I am of the school in science - publish the report showing warts and all
