Turns out the key to making things lighter than air is…light! California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel ...

Researchers at the California Institute of Technology (Caltech) say they’ve found a way to levitate and propel objects using only light — though, for the time being, the work remains theoretical. They ...

Instead of copying incandescents, GE Lighting’s Light + Form bulbs explore new shapes and "filament" designs only LEDs can ...

Specially designed materials enable objects of different sizes to be levitated and manipulated with light, thanks to new research. Researchers at Caltech have designed a way to levitate and propel ...

A new 3D printer uses light to transform gooey liquids into complex solid objects in only a matter of minutes. The printer can create objects that are smoother, more flexible and more complex than ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, first made over 60 years ago. When an object approaches the speed of light ...
