“When the sunlight shines through the blackness of space it’s black, but I was in sunlight and I was able to look at this blackness! And what are you looking at? Call it the universe, but it’s the infinity of space and the infinity of time. I’m looking at something called space that had no end and at time that has no meaning. You can really focus on it because you’ve got this planet out there, this star called Earth, which itself is in this blackness, but it is lit up because the sunlight strikes on an object, strikes on something called Earth. And it’s not a hostile blackness. Maybe it’s not hostile because of the beauty of the Earth that sort of gives it light.” — an Apollo astronaut.
