Space related topics have been a passion since my father gave me a technical book on the subject when I was only 6 years old. Physics has also been very high on my list since high-school, in particular, the nexus of information and the mattter (It from Bit x Bit from It) : In a more mundane sense, that is what the modern mining industry is all about. :-)
Information In, Ore Out. (IO)^2.

"It from bit symbolizes the idea that every item of the physical world has at bottom — at a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the resistering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe"- John Archibald Wheeler
