  • Dark Matter: Still Existing (One in a Continuing Series)

    Updated: 2012-05-23 18:46:08
    Last month we mentioned a paper on the arxiv that made a provocative claim: evidence from the dynamics of stars above the galactic disk indicates that there is essentially no dark matter in the vicinity of the Sun. I am not an expert on galactic dynamics, but nevertheless I and others were immediately skeptical, especially [...]

    On local TV last night, I somehow got reporter Dave Malkoff to take a stab at explaining quantum field theory: the world is made of fields, but we only notice the ripples within them, which we see as particles. Something about Angelina Jolie in there at the end as well.

  • Dark Matter vs. Modified Gravity: A Trialogue

    Updated: 2012-05-09 17:44:40
    It’s well known that all of our evidence for dark matter (and dark energy too, but that’s not the subject here) at the present time is indirect: it comes from observing the gravitational influence of the hypothetical stuff, not from detecting it “directly” (i.e., using some interaction other than gravitational). So it’s natural to ask [...]

    Updated: 2012-05-07 17:03:10
    “Atheism” is a fine word, and I’m happy to describe myself as an atheist.

But given a choice I would always describe myself first as a “naturalist” — [...]
