nice article at new scientist noting a few of the things we just don’t understand, titled: 13 things that do not make sense. i’m sure this list could have just as easily been called 13,000,000 things that do not make sense, but that would have been a long article indeed. the 13 things they choose to highlight are as follows: 1 the placebo effect. 2 the horizon problem. 3 ultra-energetic cosmic rays. 4 belfast homeopathy results. 5 dark matter. 6 viking’s methane. 7 tetraneutrons. 8 the pioneer anomaly. 9 dark energy. 10 the kuiper cliff. 11 the wow signal. 12 not-so-constant constants. and 13 cold fusion.
