Is it possible to ever have a straight line while the Earth is in the shape of a circle?

This is a good question and has made me think.

If the line was at 90 degrees to the tangent of the earth (that means vertical) then the curvature of the Earth would make no difference.

If the line were not perpendicular I still do not think it would make any difference.  A line is not a solid, it has no substance and hence it not affected by gravity. So in theory at least the line could just go in any direction and not be effected by the the planet on which it originates.

Others may have a different view.  I will include this question in my next wrap.
