Our world really is tiny, compared to what’s out there. I can’t help but think, wow. One of my favorite comments on this subject is from the movie Contact, when a child asks Jodie Foster’s character if there is life on other planets. She responds “If it’s just us, it seems like an awful waste of space.” The images in the link make that seem so, so true.
