I have refuted Einstein's concept of space-time continuum. I feel the need of a clarification on this issue. Space is a created entity, very subtle and super-elastic. It itself is matter. It is not a vacuum or a void. It is full rather than empty. Being the subtlest state of matter, it holds all material bodies that are reletively grosser than it. Being subjected to gravitational force of other material bodies, it is curved in different directions. Space is not relative. The three dimensions of space, that is, length, breadth, depth or height, are relative with reference to different observers moving at different speeds.The time-dimension is also relative. All the four dimensions, mentioned here, are mental constructs and relative. But time itself is a non-entity. Time is a mental construct with the occurrence of two or more events. There is no time in an imaginary eventless universe. I may give two other examples of mental constructs with phenomenal meanings.. Darkness is not a real entity. The absence of light is darkness. The blue sky is not a real entity. Still darkness and the blue sky are not nonsensical with regard to our mental perceptions. When we speak of velocity, necessarily involving dynamics, we cannot escape from the occurrences of events. And so is the inseparable association of the three spetial dimensions and the one temporal dimension. Otherwise, space which is a real entity cannot be continuous with time which is a non-entity.
