In straight lines (well, "geodesic" might be a better term), and at the speed of light in the medium they're in.
Light rays travel in straight lines called rays or beams. They propagate by transferring energy and momentum through particles or fields, such as photons in a vacuum or electromagnetic waves in a medium. Light rays can be reflected, refracted, or absorbed when interacting with different materials.
Light rays can travel through air, vacuum, and transparent materials such as glass or water. These materials allow the propagation of light by allowing the rays to pass through with little to no absorption or reflection.
Light rays travel in a straight line unless they are refracted or reflected by a medium. This straight path is known as rectilinear propagation. Light rays can also be bent when passing through different mediums with varying optical densities.
The material through which light travels can affect the speed and direction of the light rays. This is due to properties such as the density and composition of the material, which can cause refraction, reflection, absorption, or scattering of the light rays.
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.
Gamma rays travel at the speed of light because both light and gamma rays are variants of the same thing: electromagnetic radiation.
Radio waves, like light, is a form of electromagnetic radiation. Other types of electromagnetic radiation include X-rays, infrared radiation, and gamma rays. All electromagnetic radiation travel at the speed of light.
It changes the speed of the rays
If light rays did not travel through space there would be no way for them to reach Earth.

Yes, they travel some fast!
