memory is the umbrella...
"If you think time travel is like a tower - one moment is put on top of all other moments, and order/causality is maintained at any time - then any attempt at time travel would either be rectified instantly, either by recreating the only possible timeline, or by recreating another timeline, erasing the change (depending on the amount of determinism in the universe)."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
