"When I looked at the galaxy that night, I knew the faintest twinkle of starlight was a real connection between my comprehending eye along a narrow beam of light to the surface of another sun. The photons my eyes detect (the light I see, the energy with which my nerves interact) came from that star. I thought I could never touch it, yet something from it crosses the void and touches me. I might never have known. My eyes saw only a tiny point of light, but my mind saw so much more.
I see the invisible bursts of gamma radiation from giant stars converting into pure energy by their own mass. The flashes that flashed from the far side of the universe long before Earth had even formed. I can see the invisible microwave glow of the background radiation leftover from the Big Bang. I see stars drifting aimlessly at hundreds of kilometers per second, and the space-time curving around them. I can even see millions of years into the future."
