Hey!
I have some dumb-smart question
Does 1D line have physical width?
My logic says that mathematically you can go smaller and smaller,but I see there being a problem with 1D having infinitly small width in physics.

If 2D object has infinitly many 1D lines that would suggest that 2D object is also infinitly long/large - for it not to be infinitly long
-it has to have infinitly many smaller infinitys(but that seems to be also flawed)-I draw a circle and started to pull lines from center to edge to visulise it and it seemed to work,but I don't see it being a good answer.
-otherwise it's infinitly large number that is actually a number and isn't infinity atall.
English isn't my first language ,sorry :)

Hey Tarantula! Welcome to PF! :smile:

There is no width in 1D …

so a 1D line has length but no width.

(btw, you need to use the word "a" more often :wink:)

Sorry, I don't understand. :redface:
