There is a key rule of thumb (or heuristic) in science known as the Copernican Principle. It essentially says: “We’re not special.” (The “we” in question being the human race.) It’s named after Nicolaus Copernicus, who, in 1543, forever banished the Earth and its thin film of humanity from the center of the universe.
Ever since, the science view of humanity is that it’s just part of the landscape, nothing particularly special, a mere consequence of energy+time creating increasing organization in systems. We may be complex, perhaps even a little surprisingly so, but we’re still nothing special.
Yet it seems to me that, at least in some ways, we really are.

Among those who study the human mind and consciousness, there is what is termed “The Hard Problem.” It is in contrast to, and qualitatively different from, problems that are merely hard. (Simply put, The Hard Problem is the question of how subjective experience arises from the physical mechanism of the brain.)
This post isn’t about that at all. It’s not even about the human mind (or about politics). This post is about good old fundamental physics. That is to say, basic reality. Some time ago, a friend asked me what was missing from our picture of physics. This is, in part, my answer.
There is quite a bit, as it turns out, and it’s something I like to remind myself of from time to time, so I made a list.

To the dismay of physics geeks everywhere, theoretical particle physics struck out at the plate this year. Three swings, three misses. (Well, maybe one wasn’t really a swing. More a taken ball the umpire called a strike.) It was a crushing disappointment for those of us hoping for a rule-change to the game.
On the other hand, cosmology geeks got three recent home runs, so there was victory (with more coming!) for those who peer at the big and distant. On the other other hand, none of those were game-changers either. (They were just, you know, awesome.)
Since I follow both physics and cosmology, win some, lose some.
