Interrelationship between space and time

Space is an entity, an elastic matter, very subtle. Time is a non-entity. Time is a mental construct when more than one events occur. Space has three dimensions - length, breadth and depth or height. The three dimensions are non-entities, mental constructs. The three dimensions of space and the one dimension of time are relative. When two items move in space with different velocities, motion is associated with the time-dimension. Thus space and time are inter-related. However, there does not seem to be anything like space-time continuum. Imagine an event -less, motionless universe. Then only will the clarity of the concept be clear. This concept is a deviation from the Special Theory of Relativity of Albert Einstein.
