India Plans Robotic Military

The armed forces of the world, as ever, are dead set on using technology to gain an edge on the battlefield. Hence the Indian Prime Minister’s announcement that his country is starting a program to develop “cutting edge technology weapons in sensors, robotics, propulsion systems, stealth and fighting wars through use of remote technology”. I guess anything that means less people have to die is OK by me.

Light Travels Backwards

Is there anything these science types can’t do? Not content with being able to alter the speed at which it travels, now they’ve found a way to make light travel backwards. To add weirdness to confusion, these backward travelling pulses move faster than lightspeed as well. Apparently it’s not as much of a causality violation as it may sound, but I’m going to simply take their word for that.
