Circle Universe

In summary, the 1D universe could be a circle if a 1D being did determine the shape of his universe by marking a position and seeing if he came back upon himself. However, this is not necessary and a 1D universe could exist without shape.

I just want to ask - this is true only for cylindrical geometry, not for sphere, right?

Yes. In a sphere you will know your space is curved *intrinsically*, so again you don't have to talk about any space outside of the sphere, that's the point of intrinsic geometry.

FAQ: How can a 1-dimensional being prove they live on a circle?

What is a 1 dimensional being?

A 1 dimensional being is a hypothetical creature that exists in a world with only one spatial dimension. This means that it can only move in one direction, either forward or backward.

What is a 1 dimensional Universe?

A 1 dimensional Universe is a theoretical universe that only has one spatial dimension. This means that it has no width or depth, and all objects in this universe would only exist as a line or a point.

What does it mean to be a circle in a 1 dimensional Universe?

In a 1 dimensional Universe, a circle would appear as a single point. This is because a circle is a 2 dimensional shape, and in a 1 dimensional world, it would only have one dimension to exist in.

How would a 1 dimensional being perceive its surroundings?

A 1 dimensional being would only be able to perceive objects that exist in its one-dimensional world. It would not be able to see or understand objects that have width or depth, as these dimensions do not exist in its universe.

Is it possible for a 1 dimensional being to exist?

It is currently not possible for a 1 dimensional being to exist in our universe. Our universe has three spatial dimensions (length, width, and depth), and it is impossible for a being to exist with only one of these dimensions. However, in a theoretical 1 dimensional universe, it is possible for a 1 dimensional being to exist.
