- Solar Sails Are Already Old Tech- Get Ready For Solar Wings
We know that light has mass and that beaming enough light at something can push it away- solar sails that will move a craft through the cosmos are based on this idea and NASA tested that concept earlier today when it launched NanoSail-D, a nanosatellite (c ...

- Airy Beams- Light Rays Moving Without Diffraction In A Curved Arc In Free Space
One of the earliest lessons science students learn is that a beam of light travels in a straight line and fan out, or diffract, as they travel. Recently it was discovered that light rays can travel without diffraction in a curved arc in free space. These r ...
