There’s a famous play, Equus, about a troubled boy with a blinding love of horses. The boy sees a psychiatrist named Martin Dysart, who tries to understand him by trying to understand his love. Dysart is confounded by it:

A child is born into a world of phenomena all equal in their power to enslave. It sniffs—it sucks—it strokes its eyes over the whole uncountable range. Suddenly one strikes. Why? Moments snap together like magnets, forging a chain of shackles. Why? I can trace them. I can even, with time, pull them apart again. But why at the start they were ever magnetized at all—just those particular moments of experience and no others—I don’t know. 

I can trace my love, too. Why stars instead of horses, or boys, or hockey? I don’t know. I don’t know. Maybe it’s because the stars are the antithesis of darkness, of abusive stepfathers and imperiled little sisters. Stars are light. Stars are possibility. They are the places where science and magic meet, windows to worlds greater than my own. Stars gave me the hope that I might one day find the right answers.

But there’s more to my love than that. When I think of the stars I feel an almost physical pull. I don’t just want to look at them. I want to know them, every last one of them, a star for every grain of sand on Earth. I want to bask in the hundreds of millions of suns that shine in the thousands of billions of skies in our galaxy alone. Stars represent more than possibility to me; they are probability. On Earth the odds could seem stacked against me—but where you are changes everything. Each star was, and still is, another chance for me to find myself somewhere else. Somewhere new.
