Neutrinos are elementary particles that have the ability to pass through any matter. Billions of them pass through our bodies every second. Billions of them pass through the Earth and exit on the other side unaffected. They can pass through stars and travel to the other side of the universe. This is so mostly because they don't have an electrical charge and because atoms are 99.9999% empty space. Neutrinos have even the ability to pass through the nucleus of the atom or that 0.0001% that most physicists consider as the physical matter constituent of the atom, where more than 99% of atom's mass is concentrated. So, the ability of neutrinos to pass through 1 light year of lead belt is possible because the Standard model says the atom is not composed of particles with physical dimensions(quarks and electrons), but of zero-dimensional particles held together by subatomic nuclear forces - the strong force and electromagnetism, mediated by gluons and photons. On the other hand, String theory assumes that the zero-dimensional particles of the Standard model are not zero-dimensional entities but have a distinct size, although it's the smallest size that has any meaning - the Planck length - 1.6*10^-33cm. So my question is this - if String Theory were correct and strings had this almost physical size, how would at least some of the neutrinos passing through the Earth NOT collide at some point during their journey with the strings that compose matter(electrons, quarks, etc.)? If strings are energy/charge that allows neutrinos to pass through them, how can energy/charge have a physical size? Isn't that the reason why the Standard model "fell apart" at certain questions and couldn't give meaningful explanations?
