    No.

    A straight line is obtained by joining two distinct 'points'.

    on this line there lies infinite 'points' between the given end-points.

    So, a strsaight line is actually a set of POINTS.

    Theoretically, a straight line is one with a constant, unchanging slope. Perfectly plausible in theory.

    In reality, however, the natural curvature of the Earth (and Universe) makes what is very slightly curved seem straight (since it is so small compared to the Earth (or Universe)).

    So in theory: Yes.

    In reality: No, although you could argue that the existence of the theory of a straight line makes it a reality. In other words, since the theory exists, it is plausible.

    If you made a line that appeared to have a certain curve, it would in fact be straight and only appear curved because of the curve of Time-Space. So the key is trying NOT to draw a straight line.

    The relative curvature of a line, a one dimensional object, in a three dimensional space would depend on the location and speed of the observer. A line could appear to be straight, but that does not mean that it would be "really" straight. So, it all depends on how you look at it.

    no not in physical world. a straight line is required to be of zero width..... a thin wire is only an approximation of straight line due to the fact that its width is very small compared to its length and within certain context can be approximated to zero.

    shortest distance between two points. Except on the surface of the earth where the shortest distance is a curved line.

    no, because the line is made up of individual points that are so close together that it just looks like they are one connected line

    no, there isn't anything that is very straight. the real straight line only exist in theory world.

  • In theory, yes! But not in the real world; the geometry of the universe is non-euclidian.

    It is according to what prespective you are looking at, at the time you see the line.
