"Why isn't there nothingness? Nothingness would have been decidedly elegant. In the Ultimate Multiverse, a universe consisting of nothing does exist. As far as we can tell, nothingness is a perfectly logical possibility and so must be included in a multiverse that embraces all universes."
Some people suggest it's arbitrary to stop at ten dimensions. Did we run out of fingers so we decided there couldn't be any more? Indeed, if you're not assigning any meaning to the individual dimensions, then the point-line-plane postulate allows you to keep adding as many dimensions as you want. People also ask Aren't There Really 11 Dimensions? In my book and my blog I've insisted that ten is really all you need to consider all aspects of reality, and that supporters of M-Theory acknowledge that there are ways in which the 11 dimensions they are talking about are functionally equivalent to the ten dimensions string theory is talking about. The graphic at right comes from New Scientist magazine, in a recent special feature called "Instant Expert: Theory of Everything", please do follow the link to read the whole article.
Another way of showing this equivalence is to say that M-Theory proposes ten spatial dimensions plus time. With my project, I say that time isn't a dimension, it's a way of describing change from state to state within any dimension: so the tenth dimension with no time is the Ultimate Ensemble that Max Tegmark spoke of in his discussion of the different kinds of multiverse, or the timelessness that Gevin Giorbran spoke of in Everything Forever, or the Ultimate Multiverse that Brian Greene refers to in the quote with which we started this entry. As I said in my original animation, if there were no superstrings vibrating in the tenth dimension, there would be no reality precipitated in the dimensions below: no time means no vibrations, no change. And because every one of the spatial dimensions we're looking at with this project are mutually perpendicular to the others, change in the tenth dimension automatically affects the entire system in various ways.
