Straight line on the earth.

That could happen. But it cant be done alone, needs to cooperate to make it happen. And i think most people dont want to do it, because some of them are still concerned with personal interests. So what can we do. the answer could be done, but it will be very very difficult.

I do not know and I think it is impossible because the earth is round it will be hard to do such.

Since the earth is a spheroid, there is theoretically no way of connecting two points on its surface with a straight line drawn on the surface. As the surface is, in fact, irregular, it would be quite possible to find some area of it on which it would be possible to draw a straight line.

hi how in the world can anyone in his right mind thing you could draw a straight line on a curved surface, as it c annot be done. the world is curved so you will have to draw a curved line and that is self explanatory as it cannot be done. You can draw a straight line on a flat surface or a piece of paper but the world is curved.We can draw straight lines on the land but not on the curve on thed earth. that esplains itsself.

Why not? On theory, we can do that such as we draw a equatorial.

Even if the earth were an exact sphere, which it is not, a circle still has a series of very tiny straight lines that make up the circle. So, if you mean any length of a line, yes, it's possible, even if the earth were spherical. Now, if you mean a line around the world, it would only be straight in that it didn't curve a certain way, and only curved around the world. So, it would still be planar, but not "straight" like a pencil. Now, because the world isn't round, it does have flat surfaces, so it would be possible to draw a straight line on that flat surface.
