Why is outer space black when almost all areas of the sky is covered by stars? Like the Hubble Space Telescope has proven us, everywhere in the sky there is stars
That's an insightful question. The blackness of outer space is actually due to the way light interacts with the matter and elements present. Even though stars are scattered throughout space, the vast majority of space is essentially empty vacuum. The light from stars can only travel in straight lines, so the tiny particles of gas and dust in space can block the light from reaching our eyes, giving the appearance of darkness. Also, space is so incredibly huge that the stars appear very far apart from our perspective, so their light does not overlap to brighten space. Finally, dark matter and energy, which are invisible but have mass, permeate space and also do not emit light. So when we look out at the cosmos, all of these factors combined lead to the deep blackness surrounding the stars and galaxies. Does that help explain the phenomenon? Let me know if you have any other questions!
