An interesting 'dimensional' variety.
The 1st dimension is a line
The 2nd dimension is a plane or two lines connected at all points
The 3rd dimension is a solid object or two planes connected at all points
The 4th dimension we are unable to produce but researchers know from the formation of the other dimensions that it is two solid objects that are connected at all points. It is the belief of researchers that this 4th dimension is time and if we are able to 'physically' produce a copy of the 4th dimension we will be able to 'time travel'........very intriguing
