New Scientist Features : 19 March 2005, by Michael Brooks

For those of you who think our understanding of the physical world is complete. I should be asleep, but I had to read this first.

Yes, that's right. 13 things that don't scientifically make sense. And yet, there they are. Here's the list:

1) the Placebo Effect. The example given is mind blowing.
2) the Horizon Problem. Space is too uniform.
3) Ultra Energetic Cosmic Rays. They shouldn't be here.
4) Belfast Homeopathy study. Debunker is stumped.
5) Dark Matter. Why is such a ridiculous idea necessary?
6) Life on Mars. Methane carbon-14 test came out postitive.
7) Tetraneutrons. Four bound neutrons. Impossible.
8) Pioneer anomaly. The two spacecraft are off track.
9) Dark Energy. Crazier than Dark matter.
10) the Kuiper Cliff. Why matter beyond the solar system abrubtly decreases to near nothing.
11) The Wow Signal. A 37 second signal from space in 1977.
12 the Fine Constant. I can't tell you what it is, but it may not be constant.
13) Cold Fusion. You thought it was faked. Apparently it's not.
