    Explain.

    Well how would you do vector addition for time?

    My point is that if vector is scalar then how does it move in a direction which is from present to the future.

    I also heard that spacetime is a vector quantity.

    Time is a scalar quantity... time is not defined by having a direction. it is a bit hard to explain, but if you study Einstein's theory of special relativity detailed you can might give a better explanation than me.

    What about the argument have written above that it should have a direction ?

    Well you kinda say it your self... it always goes from present to the future... if the vectors of time always have the same direction, then it would be useless to talk about a vector.

    @Frostbite So you agree it goes in a certain direction from present to past ? Maybe time travel maybe possible soon you cannot say anything :/

    Well time travel you can argue easy against because if you can time travel you violate the law of conservation of energy.

    @Frostbite Well,I asked my teacher : Is time a vector quantity and he was like:stop asking me such stupid questions lol :P Well,As soon as we are progressing most of the things are being proved wrong. The latest research says that we can go in the future i guess but not go in the past.

    Moreover,If time is a scalar quantity how do we talk about present,past and future ? But we are actually travelling forward in time over a certain rate.

    @naveenbabbar What is your idea on this matter?

    If we talk about Einstein's theory of special relativity then according to that space time is a vector.

    Will you call current a vector ? It has both direction and magnitude. hmmm??

    I would more say as a contravariant of vectors...

    Ofcorse not, reason being current does not follow vector laws of addition and subtraction! A vector is quantity having both direction and magnitude + follows vector laws of addition and subtraction. Hence time is not vector.

    But times move in a certain direction ?

    CURRENT ALSO MOVES , why dont you compare with that ?

    But,Vector is defined as something which has a certain direction and magnitude.

    AND FOLLOWS VECTOR LAWS OF ADDITION..that is very important! ->current is not a vector since it does not follow that addition law<-

    So a vector should follow the laws of addition ?

    Otherwise,It is not a vector.

    Becuase you think of it as dimension... how ever it is wrong... space time is not a vector quantity either.
