In this short report we speculate the spacetime dimension in our universe , by using both the Kasner solutions to the Einstein field equations and the Kaluza-Klein concept of the extra dimension. Surprisingly around the past Big-Bang, the space- time dimension may have been two dimensional (1+1) , and in the future the spacetime dimension may tend to three dimensional one (2+1) , though our observable space-time is four dimensions at the moment. This is a toy model.
