One of the really fascinating things about the Internet and modern science is that it has allowed the lay person (to steal a religious term) to share in the excitement of new discoveries. Like this:
In a series of coordinated announcements at several US laboratories, researchers said they believed they had captured dark matter in a defunct iron ore mine half a mile underground. The claim, if confirmed next year, will rank as one the most spectacular discoveries in physics in the past century.
I remember hearing recently about an alternative theory that didn’t require the existence of dark matter. It’s mentioned briefly at the bottom of the article, but extra points to anyone who can send me a better summary of it.
Also, for extra mind-blowingness:
Some dark matter particles could explain why ordinary matter is not radioactive, while others may help scientists understand why time – so far as we know – always runs forward.
