      • MAKE YOUR OWN WHITE HOLE Simulating the event horizon of a white hole—an inside-out black hole that permits no light to enter—is as simple as letting water from the tap pour onto a flat surface, as shown here... iStockPhoto
      • HAWKING RADIATION Hawking Radiation is the faint glow theorized by physicist Stephen Hawking to stream from a black hole due to pair creation, the simultaneous birth of twin particles of light, near the event horizon... Image courtesy of Ulf Leonhardt
      • "FERRARI LASER" To have any hope of detecting faint radiation emanating from an analog of a black hole event horizon in a new laser-based method, researchers will have to create short, high-intensity laser pulses shaped like a shark fin... Image courtesy of Ulf Leonhardt
      • PRISM The supercontinuum output of the microstructured fiber dispersed by the prism (right) onto the screen (left). The prism separates the colors of light. Image courtesy of Chris Kuklewicz

      • OVER THE HORIZON Experimental setup for measuring the shortening, or blue-shifting, of an infrared beam's wavelength at an event horizon in a spool of optical fiber (blue circle added for clarity). Colored lines show the paths of incoming laser pulses (red), the infrared probe light (green) and a beam for probing the mixture of the two (magenta)... Image courtesy of Chris Kuklewicz
      • SUPERCONTINUUM SPECTRUM Detail of the broad spectrum, or supercontinuum, light output from a microstructured fiber used to create an analog of a black hole's event horizon. Dispersed by a prism and projected onto the screen, the light contains the full rainbow... Image courtesy of Chris Kuklewicz
      • EVENT HORIZON Researchers have reproduced an event horizon similar in principle to ones found around black holes by shining laser pulses down a microstructured, or microscopically patterned, optical fiber, shown here... Image courtesy of Chris Kuklewicz
