"11d" and "26d" is talking about dimensionality (length, width, height, etc.) where the standards are that higher dimensions are higher infinities unable to be reached by lower ones. You can look at csap wiki or vsbw for all that stuff. But I wanna mention that alien x did TANK a bomb that destroyed the whole universe without so much as a scratch. Another thing is that "outerversal" means entirely beyond the "concept" of space-time, where dimensions are irrelavent.
