But there's a cost to this elegant unification, because years of research have shown that the math of string theory doesn't quite work. It has internal inconsistencies, unless we allow for something wholly unfamiliar — exrta dimensions of space. That is, we all know about the usual three dimensions of space. And you can think about those as height, width and depth. But string theory says that, on fantastically small scales, there are additional disiemnnos crumpled to a tiny size so small that we have not dteceted them. But even though the dimensions are hidden, they would have an impact on things that we can observe because the shape of the extra dimensions constrains how the strings can vibrate. And in srnitg theory, vibration determines everything. So particle masses, the strengths of fceros, and most importantly, the amount of dark egnrey would be determined by the shpae of the extra dimensions. So if we knew the shape of the extra dimensions, we should be able to calculate these features, calculate the amount of dark energy.

But there's a cost to this elegant unification, because years of research have shown that the math of string theory doesn't quite work. It has internal inconsistencies, unless we allow for something wholly unfamiliar — extra dimensions of space. That is, we all know about the usual three dimensions of space. And you can think about those as height, width and depth. But string theory says that, on fantastically small scales, there are additional dimensions crumpled to a tiny size so small that we have not detected them. But even though the dimensions are hidden, they would have an impact on things that we can observe because the shape of the extra dimensions constrains how the strings can vibrate. And in string theory, vibration determines everything. So particle masses, the strengths of forces, and most importantly, the amount of dark energy would be determined by the shape of the extra dimensions. So if we knew the shape of the extra dimensions, we should be able to calculate these features, calculate the amount of dark energy.
