When light reflecting off and being emitted from people leaves Earth and travels through outer space, it generally behaves in a manner similar to any other form of light. However, the appearance of light from people in space depends on various factors such as the intensity of the light source, the distance from the observer, and the surrounding environment.
In the vacuum of space, where there is no atmosphere to scatter or absorb light, the light would travel in a straight line until it encounters an object or is absorbed by another medium. If a person in space were illuminated by sunlight or artificial light sources, their body would reflect and emit light in different wavelengths, primarily in the visible spectrum.
From a distance, the light reflecting off a person's body would appear as a small point of light, similar to a distant star or planet, assuming the observer is far enough away. If the observer were closer, they would be able to perceive more details, such as the shape and features of the person.
The color of the light emitted and reflected by people depends on various factors such as the lighting conditions and the person's skin tone, clothing, or any other objects they may be carrying. Sunlight is composed of a spectrum of colors, and objects reflect or absorb certain wavelengths, giving them their distinctive colors.
It's worth noting that in the vastness of space, where light can travel for great distances without significant obstacles, the intensity of light from an individual person would diminish as it spreads out over a larger area. This means that the light emitted from people would become fainter the farther it travels from its source.
Overall, the appearance of light from people in outer space would depend on the specific circumstances and the observer's distance, but it would generally manifest as small points of light with potential variations in color and intensity.
