"past. present. future. and the gravity between them" follows the internal journey and reflections of a young boy, left behind as a baby by his parents when conflict between humans and robots erupted on the close-orbit space colony they called home. Found by a collective of robots that remained on the colony after all humans had relocated to Earth, he was raised as if he was their own.

Years have passed now, and as he has gotten older he has begun to ask questions. Who were his real parents? Are they still alive? Why did they leave him behind? Is Earth really as broken and dangerous as all the stories have made it seem? His community of robots does not have the answers he seeks, and any answer they do give him doesn't seem to temper his insatiable curiosity.

He's now faced with the struggle of how to figure out who he really is and what type of life lies ahead of him. He knows that if he wishes to find the answers to his questions, he himself must be the one to take action and accomplish his goals, even if that means leaving behind the life he has known until now.
