    Re: vector

    I don't think of time as a vector quantity, neither do I think of it as being directed anywhere. Good question though.

    Another way to think of it is that time is always in one direction, so there is no need to mention a direction for it. Or you could look at it mathematically, for time to be a vector it should hold under vector addition, but when your adding time "vectors" its really just the addition of individual times. So its just scalar addition and hence a scalar quantity.
