Does it include multiple universes? and does each universe have to be in different dimensions like our universe right now is 3D (not including time) or 4D (including time) can there be another one or two or one hundred other 3D/4D universe?
 
Physics news on Phys.org
And does the String Theory include Hyperspace?
 
hello? anybody?

all the answers to your questions are in the above link. Just read the text with the title : introduction to string theory part 1,2 and 3...all is in there.

It will answer questions like why extra dimensions, what do they represent and how can we possibly "see" those extra dimensions...

This is an alert about a claim regarding the standard model, that got a burst of attention in the past two weeks. The original paper came out last year: "The electroweak η_W meson" by Gia Dvali, Archil Kobakhidze, Otari Sakhelashvili (2024) The recent follow-up and other responses are "η_W-meson from topological properties of the electroweak vacuum" by Dvali et al "Hiding in Plain Sight, the electroweak η_W" by Giacomo Cacciapaglia, Francesco Sannino, Jessica Turner "Astrophysical...
https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...
