In summary, the conversation discusses the concept of a geometric line as a one dimensional mathematical object that is not a physical object. The use of coordinates to describe physical objects and the usefulness of lines and points in this description is also mentioned.

Then why do we describe physical objects with coordinates (i.e. points)?

Basically because it is an extremely good way of describing objects and the positions of objects that let's us make useful, accurate predictions.

For heaven's sake, don't tell the string theorists.jedishrfu said:A geometric line is a one dimensional mathematical object. It's an abstract idea. It's not a physical object that you might see, touch or run into.

A line in space is a one-dimensional geometric figure that extends infinitely in both directions. It has no width or thickness and is often represented by a straight, continuous curve.

A line in space exists in three-dimensional space, whereas a line on a flat surface exists in two-dimensional space. This means that a line in space can extend in all directions, while a line on a flat surface is confined to only two directions.

No, a line in space is infinite and has no definite beginning or end. It can be extended infinitely in both directions.

A line in space can be represented by a straight, continuous curve, similar to how it is represented in two-dimensional space. It can also be visualized using mathematical equations or vector diagrams.

Lines in space play a crucial role in various fields of science, such as mathematics, geometry, physics, and astronomy. They help us understand the concepts of distance, direction, and movement in three-dimensional space and are used in various scientific calculations and models.
