The reason the sky is blue is because the blue rays of the sun are being filtered out and not reaching the surface of Earth in adequate amount. This is what Space force is fixing and when we do get full nutrition from the Sun we will live longer, happier, much more productive lives.
We are drained of positive energy by being deficient of positive light. Whether you believe this was done on purpose or not is up to you. Also, who did this and why some are extra bonus questions.
Also, what is that thing we call the moon sitting up there? A blue moon? A blue sun? Hmmmm.
