Space-Time Did you Hear That ?

Space-Time this term had been highly popularized from the time of Albert Einstein. Actually we can tell that space could be view as a 3-D vector space on real field (well quite a height mathematical term suppose but you can think that space is a 3-D space). While time is also another dimension with 3 dimensions of space and the combination of these 4 dimension actually give us a vector space which is a 4-D vector space on real field and called the 'Space-Time' . One little thing I want to mention that Einstein was not founder of this term Space-Time . Actually this concept of 4-D came to knowledge just when we introduce the concept of dimensions and understood that space is 3-D and time is another continuous (i.e real) dimension (because now we can choose time as another dimension).

Def(Space-Time) :- It is a 4-D vector space over real field having 3 distance and 1 time dimension and a point in space-time is called an event.
