why do I have fireflies in my mayonaise jar and not dark matter?

if dark matter makes up 80% of our universe shouldn't I be filling my mayonnaise jar with it instead of fireflies by now?

  • Aug 9 2012: To the best of my knowledge, "dark matter" is a code word for something physicists know almost nothing about.

    Given how little we know about dark matter, your mayonnaise jar could be chuck full of the stuff and you would have no way of knowing.

    Isn't it interesting that for all these years the particle physics folks have been pretty much mystified by gravity. Now just when they are, maybe, getting the Higgs boson in their sites, along comes the complete mystery of dark matter. Sounds like a good time to start a career in theoretical physics.
    • Aug 10 2012: there are SO many mysteries, and it seems like solving one just creates five more!
