What do you mean "nobody has any idea what is in the center of the earth"? Scientists have a very good idea about what is at the center and the middle of the earth for that matter based on extensive, albeit indirect evidence from a great many disciplines. It's solid metal and liquid metal respectively, not solid rock or magma like someone else in the thread suggested.
Furthermore, a theory when used by a serious scientist is not some willy nilly half-assed guess, but an educated hypothesis based on a lot of evidence. So don't dismiss it that quickly unless you have something better to offer in it's place.
