Researchers create portable black hole

Posted by in categories: cosmology, physics, transportation

Essentially from a disposal device to even warp drive hoverboards to even like gravity field control to even like hovering spaceships.


Physicists have created a black hole for light that can fit in your coat pocket. Their device, which measures just 22 centimetres across, can suck up microwave light and convert it into heat.

The hole is the latest clever device to use ‘metamaterials’, specially engineered materials that can bend light in unusual ways. Previously, scientists have used such metamaterials to build ‘invisibility carpets’ and super-clear lenses. This latest black hole was made by Qiang Chen and Tie Jun Cui of Southeast University in Nanjing, China, and is described in a paper on the preprint server ArXiv1.

Black holes are normally too massive to be carried around. The black hole at the centre of the Milky Way, for example, has a mass around 3.6 million times that of the Sun and warps the very space around it. Light that travels too close to it can become trapped forever.
