Another poem that goes so well with the photograph behind. So many of us think we live in the real world, that it's more real than the one at large. But science and discovery is beginning to tell us we are all wrong, so let's enjoy the journey. :-)
I really like both the literal and metaphorical juxtaposition of tide pools in the poem. Also that the tide pools will be reflecting the stars that we may one day visit.
As a child, I spent many hours poking around in rock pools and it's so true, they are miniature worlds dictated by the ebb and flow of the tide. And I suspect that they are the real world, because if something happens to their ecosystem, it's a warning to us. Whenever we upturned a stone, for example, an eel would flip and swim off to hide. Now there are none on my childhood beach. :(
