speed of light
"The speed of light is like a semi-permeable barrier that only self-awareness is able to make the squirt gun thru. It is like a self protecting membrane which says, since stars and biology most both metabolize gravity into charge - only the worthy should succeed."
"The speed of light is like a barrier. You cannot cross it, but you can be already on the other side, where the neutrinos might be.
Photons are exactly on the wall : they cannot go any slower or faster."
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.
