Four-Vector Concept

The Definition

Four-vector space is known as ‘Minkowski space’ i.e. space + time.

Need of Four-vector

To treat space and time on equal footing and enlarge our 3D Euclidean space to 4D space-time manifold, four vector concept is introduced.

In a four vector, we have 4 components (3 for space and 1 for time), instead of 3.
