A physics extravaganza

For today's post: exciting goings-on from the wide world of physics. We'll begin with "Latest search for dark matter draws a blank."

If only the hunt were this simpleDark matter, you'll recall, is hypothesized stuff that (a) exhibits its presence through its gravitational effects on familiar/normal matter, for example on the rotational characteristics of galaxies and (b) doesn't interact with electromagnetic radiation, of which ordinary light is an example (hence the "dark" part of the name)....
