Q: do you think about D A R K  M A T T E R sometimes?
A: i had to think about it a lot in the early stages of writing "history of the entire world, i guess" and i've basically concluded that 'dark matter' means 'we don't know.' the term 'dark matter' seems to be a temporary nominal place holder for whatever doesn't currently add up about the universe, particularly relating to gravity and the over all 'expansion' of the universe. i don't think anyone understands it well enough to actually say that it's 'matter' or 'energy'...... you might as well just call it space monsters for now
