This assume string theory is true. As of now, there are no proof that string theory is true or even to disprove it. In fact entire "theory" is not even provable making it label as "theory" very questionable. String theory at this stage is like Madoff Securities in 90s. Everyone assume it was legit. As long as it kept churning out dividend payout, it is good. But underlying they never ever have to be audited. They never even have to invest anything. As long as "string scientists" keep writing some fanfic things like this parallel world, it is good and legit. The math is so convoluted they kept inventing new particles called supersymmetries. As of today NOT A SINGLE of those particles found after decades. And we got Higgs proven already via the Std Model. At this point many it is as good as treating "string theory" as "alternative science" and fovus on more provable physics stuff so as a whole of humanity we able to better use our resources to advance our understanding of the universe instead of keeping the tenure job of these stringists in their respective physics department. Dont make it as a bitcoin energy sucking in physics world.
