[no_leaf_clover]

From an article (oddly dated March 19th?) from New Scientist. Here are their 13 things that don't make sense:

1. The placebo effect
2. The horizon problem
3. Ultra-energetic cosmic rays
4. Belfast homeopathy results
5. Dark matter
6. Viking's methane on Mars
7. Tetraneutrons
8. The Pioneer anomaly
9. Dark energy
10. The Kuiper cliff (10th planet?)
11. The 'Wow' signal
12. Not-so-constant constants
13. Cold fusion

They provide further info on each in the original article.

Thanks for posting this. I didn't knew that there are scientific proofs for existence of a 10th planet...

Yeah, there's been kinds of circumstantial evidence ever since the outer planets were discovered with unexplainable orbits. No one can seem to find the body that's causing it, though.

It could be taking a highly elipical orbit off of the normal plane that most of the planets take. It'd take a while to find one like that.
