No. If you read the quote
| Imagine the strangest inhabited universe you can conceive of, places where gravity operates linearly and electromagnetism by the inverse cubed rule and topology has 13 basic dimensions instead of 17. |
That sentence means that, in the ordinary universe that the events of Transformers happen, there are 17 dimensions and to imagine a universe in which the number of dimensions were instead 13. And he
also mentions that this universe has gravity, as well as electromagnetism, that functions differently than the main Transformers universe.
In this sentence he is giving a hypothetical universe in which the laws of physics are different than the normal Transformers universe. And the examples given for the different laws of physics are gravity, electromagnetism
and dimensions. The dimensions were just one example out of 3 that he mentioned on how this universe is different.
He then proceeds to say
| How alien it must be. Then ponder the wildest universes those beings could articulate. |
Here he says that the creatures inhabiting this universe would have a different understanding of the world than us, and that
their hypothetical universe would be so incredibly different than anything we could ever come up with.
And finally
| Then realize that even these musings fail to capture the uncountable infinities that exist in the Omniverse. |
He finishes up with saying that even these hypothetical universes that these creatures could come up with, that are so alien and incredible that we could never imagine, are nothing but a grain of sand, so to say, in the greater uncountable infinities in the Omniverse.
He is saying that there are so much abundance of universes that
anything you can imagine, and more, is possible within this "Omniverse".
It makes little to no sense, grammatically, to say that he was referring to spatial dimensions when he made this statement.
