Why Earth's Sky is Blue, Space Black: The Science
•The sky appears blue due to Rayleigh scattering, where Earth's atmospheric gas particles scatter blue light more effectively due to its shorter wavelength.
•Space appears black because it is a near-perfect vacuum with no particles or gases to scatter sunlight, causing light to travel in a straight line and remain unseen unless it hits an object.
•Astronauts experience Space Adaptation Syndrome (SAS) in microgravity, requiring time for their bodies to adjust to the environment.
Why It Matters: This explains the science behind Earth's blue sky and space's blackness.
