The aim of /v/Physics is to build a subverse frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
At this early stage /v/physics is open to any physics related question or comment. Including physics homework problems, physics GRE problems or questions, or questions about jobs in physics.

It's just an interesting trick. Nothing was given negative mass. Part of a larger system was given a negative effective mass, with the unusual behavior powered by lasers.
