Broken Laws and Invisibility!

One of the major sci-fi dreams of science is to be able to shield things from view, or make things invisible. just recently, scientists have made this feat possible, by creating a "meta-material" which bends light around the material; showing only what is behind it (invisibility). However, these materials only worked on very small objects.

Stanford researchers, however, have discovered a way to make magnetic fields manipulate light. Previously, light was not affected by those fields, but by forcing them to bend and reverse, we are breaking a key law of physics: the Time-Reversal Symmetry of Light. By sending photons backwards, their properties could change, and we would essentially be sending them backwards in time. Breaking such a "set-in-stone" law also goes to show that others can be broken, which theoretically would allow us to do all the fun things which were deemed impossible. Things like time travel, FTL (faster than light) travel, teleportation, infinite power generators, and much more. The very definition of a nerd-gasm.
