It's always straight - as far as the light is concerned.
If space is curved then the light follows the curve.
Yes, light can travel forever in the universe unless it is absorbed or scattered by objects in its path.
Light waves travel in straight lines unless they encounter a medium density change or are reflected or refracted by a surface. This results in bending or scattering of the light waves along their path.
Light travels in a straight line, moving in a straight path known as a ray.
Light rays travel in straight lines due to the principle of the shortest path, known as Fermat's principle. Light travels along the path that minimizes the time it takes to travel from one point to another. This results in light rays following straight lines in a uniform medium.
Yes, light rays travel in a straight line in a homogeneous medium. This is known as rectilinear propagation of light. If the medium is not uniform, such as in the presence of a lens or when light undergoes refraction, the path of light may bend.
The way light travels depends on what is in it's path.
From rectilinear propagation of light.

mode means path, the way in which light travel, in the fiber means angle in multi mode fiber light can travel in more then one angle so it is called multi mode fiber. but in single mode fiber there is dedicated path or single path through which light beam/source can travel.

Light will almost always travel from one place to another along a path that takes the least amount of time. This does not imply that it will take the path involves the least distance all the time.
Yes, light rays travel in a straight line in a homogeneous medium. This is known as rectilinear propagation of light. If the medium is not uniform, such as in the presence of a lens or when light undergoes refraction, the path of light may bend.
If there is an unobstructed path, it can continue traveling practically forever.
Yes, optical fibers use total internal reflection to guide light along their length, allowing the light beam to travel in a curved or twisted path within the fiber. This property enables the efficient transmission of light signals over long distances with minimal loss.
