Two math models combine to solve an age-old problem.
Decades-old mathematics might finally explain some features of the 'oddballs' of matter: granular materials that sometimes behave like a solid, and at other times flow like a liquid.
Strange patterns in the orbits of small objects in the outer solar system could be explained by gaps in our understanding of gravity rather than an as-yet-unseen new world
A team of physicists have penned a study suggesting the mysterious Planet Nine, or Planet X, may not even be a planet at all but something entirely.
Planet Nine is proving difficult to pin down.
