I have enjoyed looking at photographs of the wonders of space. Since my childhood, I have been fascinated by colorful nebulas, the countless lights of stars spreading against the endless expanses of darkness, and the mysteries of black holes. I used to imagine what the end of our universe might look like. Humanity has made successful flights to the moon, sent rovers to Mars, and studied asteroids but it feels as if no matter how much we learn, we have only scratched the surface of understanding our universe and it will always be beyond the reach of human intellect.
