Yes, in a vacuum or empty space, light can travel indefinitely without hitting anything. Light is an electromagnetic wave that doesn't require a medium to propagate through, unlike sound waves that require a material medium like air, water, or solids. In the absence of any obstacles or particles to interact with, light can continue to travel in a straight line, essentially indefinitely.
This is why we can observe distant stars and galaxies from Earth. The light emitted by those celestial objects travels across vast distances of empty space, reaching us without being obstructed by any intervening matter. It allows us to see objects that are billions of light-years away.
However, it's important to note that light can be affected by other phenomena in space, such as gravitational fields or the expansion of the universe. These effects can cause light to bend or redshift, altering its path or wavelength. But in the absence of such external influences, light can travel through empty space without hindrance.
