Following in the footsteps of French mathematician Urbain Le Verrier, who predicted the existence of Neptune by analyzing small deviations in Uranus' orbit around 150 years ago, a team of astronomers has recently been able to infer the existence of a second exoplanet in a system where only one was visible.

According to a paper published in the online journal arXiv, it would appear that dark matter interacts with the human body more often than scientists first calculated. The new results suggest that the elusive stuff interacts with atoms in our bodies around 100,000 times per year.
Dark matter is a quantity that was ... |
