Constellations

It’s probably too early in the day for this, but here’s Tim Carmody on constellations:

After the Coper­ni­can rev­o­lu­tion, a con­stel­la­tion isn’t even a con­stel­la­tion. Instead, it’s a two-dimensional flat­ten­ing of a three-dimensional real­ity. Actu­ally, we should prob­a­bly say a FOUR-dimensional real­ity. The light from stars at vary­ing dis­tances, leav­ing their sources at var­i­ous times in the dis­tant past, gets mis­taken, from our earth­bound point-of-view, as a simul­ta­ne­ous two-dimensional pattern.
