Hey, I'm a BIG lover of science, but it seems so amazing to me that physicists would be so worried about why all the other known forces of nature are 30 orders of magnitude stronger than gravity that they'd be willing to explain it by postulating the existence of an extra dimension that is 70 orders of magnitude smaller than any of the other known dimensions.
I mean, by all means, explain gravity. Very worthy goal. But you leave us laymen scratching our heads when you say we must explain it because it's 30 orders of magnitude weaker than the other known forces, then blithely try to explain it by introducing a new dimension that is 70 or so orders of magnitude smaller than any other known dimension. If gravity is so darned discrepant as a force, you've just introduced a dimension that is 40 orders of magnitude more discrepant than gravity was to begin with. With all due respect, and believe me, I have about a hundred orders of magnitude more respect for what science does than for what almost any other person in our society does.
Yes, remarkable, eh? By trying to explain away 30 orders of magnitude, they introduce a total discrepancy of 100 orders of magnitude in two different realms.
