“ Piece of evidence of the existence, influence or action of someone. Something or some event “
This piece has this meaning for me, is the evidence of my time here, in this space, in this universo; and also is related with the mistery of the Universe and what we really know about it.
Einstein used to say that the most powerfull experience we could have is mistery, without it, we are dead.
Everything we know about the reality of the Universe is uncertain, what today is given by valid, tomorrow it will be discard by new discoveries by advances in science and technology. So, we only have some traces of where we came from or where we are going.
This is life, uncertainty and mystery, but also a challenge.
