There are an infinite number of things that make the universe magical.  Here are some that I think are important.

- It exists.  The Universe is something from nothing.  The Big Bang just happened.  It may have been caused an event in a larger dimensional arena, but that must have come from something, and so on.  Matter, Energy, and Spacetime all just is.  

- It’s organized.  Instead of being violently chaotic or monotonously uniform, the universe (or at least the part we inhabit) is structured in a way that spontaneously self-organizes into structures, cycles, and patterns.  Atoms, Molecules, Life, Planets, Stars, and Galaxies all arise from the the interactions of their components.  The universe has symmetry.  The laws of nature are the same in this part as in every other part, and so the structures that arise are similar, but each one is unique.

-It’s Big.  Soooooooo Big.  Gigantic.   Incomprehensibly huge.  So big that everything that can exist, does. Infinite.  

-The universe is self aware. On many scales the universe observes itself.  You are it observing itself right now, which means;

- You are the universe.  Even though you experience a small part of the universe called your body, that part is influenced by and influences all other parts.  So you are inseparable, unified with the entire cosmos.
