In space, light and darkness are relative terms that depend on the presence or absence of light sources. In the vast expanse of the universe, there are areas where light is scarce, such as deep interstellar space, and regions where light is abundant, such as near stars or galaxies.
If we consider traveling through space without any external sources of light, such as stars or distant galaxies, the surroundings would appear dark or pitch black. However, even in such areas, there are usually faint background emissions of light, such as cosmic microwave background radiation, which is a remnant of the Big Bang.
It's worth noting that spacecraft and other equipment used for space travel often have their own artificial light sources to illuminate the interior for various purposes, such as conducting experiments, navigation, or simply providing visibility for the astronauts or cosmonauts on board.
Therefore, while the concept of traveling through space without any light or darkness may not be achievable in the strictest sense, it is possible to experience environments that are predominantly dark or devoid of discernible light sources.
