this blows my mind

"A few billion years after that, you'll be standing on a hill looking up on a clear night, and the sky will be close to pitch black, no Milky Way, no constellations, just blackness, because the stars we see today are speeding away from us, leaving a faint, infrared light. It will be very lonely. (Unless you're a telescope-wielding butterfly. Butterflies can see infrared. Distant retreating stars will be visible to them. To us, those stars will be invisible.)"
