Time is used in the constructors of both Space and Universe.
Space uses Time in its constructor to validate the amount of dimensions across them, but don't keep Time as attribute.
Universe, however, only keeps Time as attribute.
The instance of Time informed in the constructors of both Space and Universe must be the exact same, therefore, a validation must take place to match them somehow.
