The clever boffins have finally managed to break the speed of light. A light pulse was so fast that it "exited a specially-prepared chamber before it even finished entering it." picked by TheStep 1 year ago

As soon as you are born, you are influencing light. From the day of your birth, you can see how many stars that light has reached. Works only on stars up to 50 light years away. picked by Moe 5 months ago

It was supposed to be the one speed limit you cannot break. But scientists claim to have demonstrated there is the possibility of travel faster than the speed of light. picked by AutumnLotus 1 year ago

Science knows you can move a solid with the heat generated from a light source. This discovery shows that light actually exerts a physical pressure capable of moving solid matter. picked by BrownTrout 1 year ago

Most seem very cheap and easy, no real tech expertise (unless you don't know how to use duct tape). picked by dollyllama 2 years ago

Scientists at the University of St Andrews have used lasers to simulate a black hole in their laboratory. Professor Ulf Leonhardt and Dr Friedrich König used intense light pulses to create an artificial `event horizon' - the defining feature of a black hole known as `the point of no return'. The development may allow researchers to test Professor Stephen Hawking's theory that black holes are... read full post picked by AutumnLotus 6 months ago
