Many people ask: why is it always dark in space, even though the Sun is closer there than on Earth, and nothing interferes with the spread of light?
This information is reported by Ukr.media, quoted by URA-Inform.
The answer lies in understanding the nature of light. Although light can be thought of as a wave, it is more convenient to think of it as a stream of particles, like a cloud of flying balls. We only see objects because light is reflected off them. If light is absorbed, as is the case with a black body, the object becomes invisible.
In space, darkness is due to the lack of matter for light particles to “bounce off”. This leads to the simple fact that there is nothing in space. There are no objects that can reflect light back to our eyes, so everything appears to be immersed in darkness. Although there is some matter in the vacuum of space, it is not enough to fully reflect light. However, planets and spaceships are visible because they reflect light well enough.
An interesting question is why the earth's atmosphere appears illuminated. The fact is that it is illuminated due to the reflection of light from the surface of the planet. Although air itself is not a dense source of reflection, it contains particles of dust, water vapor and other elements that contribute to the scattering of light. This complex of factors creates the feeling of atmospheric illumination.
