So, distant planets, stars, nebulae, and galaxies provide us with wondrous appearances for which we have some explanations, but still some questions. We know we will never reach the distant objects that intrigue us; the distances are too far for travel at the speeds we can generate in our rockets. We take a passive journey instead. We let the light, neutrinos, and radio signals of the distant objects bathe our instruments, and then we stare at the images, counts, and graphs they produce. Wonders. Some understood, but still wondrous.; some mysterious and very wondrous.
We have closer wonders: The Grand Canyon, Mt. Everest, the Great Barrier Reef. These we can explore and understand, but their majesty is still wondrous, and some parts of what they are still remain a bit undiscovered. They are, however, places that humans can visit, explore, sample.
Among the wonders there are none so mysterious as you. Move a muscle. Wonder! Read this. Wonder! Communicate with another. Wonder! Love. Wonder!
The mysterious wonders of the universe are less complex than you. You have what they all have, from the subatomic to the atomic, to the interacting forces within. You have all the physical wonder that the universe anywhere at any time has. But you have more. Somehow in processes as yet not completely understood, you can wonder. No wonder beyond you can wonder. Your wondering is the greatest wonder.
