i mean when you think about it everything thing in life has thinkness...ok if you drew a line on a piece of paper would you call it 1 dimensional and y...it has a some thickness in it.(or whatever you call it i forgot lol im kinda dumb and 12)

kat your answer didnt make sense

Yes, it exists. While, these objects are tecnically in 3 dimensions, electrons in them will behave as though they were 1 dimensional. They are called quantum wires. They are so thin in x and y but so long in z that they are considered 1 dimension objects. Carbon nanotubes for instance can be nanowires. Another example of 1-dimensional object that comes to mind is the study of waves on a string.
quantum dots are considered to be 0 dimension. They are used to dope transport and optical properties, in lasers for instance. I heard about some uses in biology too but i don't know so much about them.
Also, you can have problems solvable in 1 dimension, like a train on its rails without the object being really 1-dimensional.
So, the short answers is no, 1 dimensional objects don't exist, but 3-dimensional objects can behave as though they had only one dimension.

Your question gets at the thingyness of thinghood.
For instance, time is one dimensional, but is time a thing?
We talk about it as if it were sometimes, but we can't really experience it like we do an apple.
If you want your thing to be normally thingie, then no, because we usually experience things in 3 dimensions.
If you are willing to accept a one dimensional thing as only having the thingness available in one dimension then you have things like time and a rotating black hole as was mentioned earlier.
Dimension is a root concept we cannot abstract well and retain it's commonsense meaning. That is why in physics dimension is treated more like a mathematical construct.

The number of dimensions is a result of what is significant. So if I ask you to draw a map of the floor plan in a house, you would be making a two-dimensional drawing where width and length are the dimensions that are to be considered. If I also wanted to know the height of the walls and other objects on the floor plan, then I would be seeking a third dimension.

If something had a non-zero mass and did not have 3 dimensions, then its density would be infinite (because its volume would be zero).
The closest type of object that I can think of, is a rotating black hole. In a "normal" black hole, all the mass collapses towards a single point (zero dimension). In a rapidly rotating black hole, the singularity is mathematically represented as a circle (the one dimension line closed on itself), not as a point.
PS: From (1)
"The singularity inside a rotating black hole is expected to be a ring, rather than a point, though the interior geometry of a rotating black hole is currently not well understood."

Not in reality.
In mathematical terms, a "line" is one dimensional - but that is an imaginary necessity of euclidean geometry - same as a "point" or "plane."

yes, but in theory. nothing tangable will be one demensional, or two for that matter.
