Re: Why are there 3 dimensions?
Ok, I'll bite...
General Relativity states there are three spacial dimensions, plus a fourth: time.
String theory posits there are at least 10 spacial dimensions, plus time.
Bosonic string theory suggests there could be as many as 26.
Three is only magical in the bedroom, but it must be cautioned that under such conditions the uncertainty principle can be seen working at macroscopic levels. ;)
