About the name

Aleph is named after a short story written by the Argentinian author Jorge Luis Borges, The Aleph. It tells of a magical place that encapsulates all other places:

Truth cannot penetrate a closed mind. If all places in the universe are in the Aleph, then all stars, all lamps, all sources of light are in it, too.
