That light you see from stars has been traveling for far longer than that. From the sun, light takes about 8 minutes to get to earth, next closest stars are about 4 light years away, many of the stars we see have died out long ago and we're just seeing light that was emitted millions or billions of years ago.

Bad idea about the red light. Cannabis photosensitivity is highest to red and far red. Get the red out and go with complete darkness.
