what's more worrisome is that 是对的
意思是 "更令人担忧的是"
what's = that which is = the thing that is
they pay attention to the physical appearance rather than他们重视外表而不是
the soul force of the stars这个短语可能有错, it doesn't make sense.
原句的 physic 应该是 physical那若what‘s改为what是对的吗不对，按语法 what 后面要加动词 iswhat is 在原句里被简写为 what's 。
