![]() “We’re exploring, excitedly, the possibility that the photon ring is the thing that you have to understand to unlock the secrets of Kerr black holes,” he said, referring to the kind of spinning black holes created when stars die and gravitationally collapse. Now Strominger is making his own U-turn and trying to convince other theorists to join him. “And I thought of the photon ring as some sort of technical, complicated thing which didn’t have any deep significance.” “I had taken the view that the event horizon was what we needed to understand,” said Andrew Strominger, a leading black hole and quantum gravity theorist at Harvard University. Quantum gravity theorists seeking a truer, quantum description of gravity have therefore looked to the horizon for answers. But space-time warps so much inside black holes that general relativity breaks down there. Throughout most of the cosmos, gravity tracks with curves in space and time as described by Albert Einstein’s general theory of relativity. It makes sense that researchers have been preoccupied with the event horizon, since it marks the edge of their knowledge about the universe. If you detect the photons, “you’re going to see every object in the universe infinitely many times,” said Sam Gralla, a physicist at the University of Arizona.īut unlike the iconic event horizon of a black hole - the boundary within which gravity is so strong that nothing can escape - the photon ring, which orbits the hole farther away, has never received much attention from theorists. Some of these photons keep circling the black hole practically forever.ĭescribed by astrophysicists as a “cosmic movie camera” and an “infinite light trap,” the resulting ring of orbiting photons is among the weirdest phenomena in nature. ![]() A rare few, however, skirt the hole, making a series of abrupt U-turns. Once you are done, you can play around with an array of 3D, screen resolution, and tiling options available, and choose one that befits you.When photons hurtle toward a black hole, most are sucked into its depths, never to return, or gently deflected away.

You can do this by following a simple process: 1. All you need to do is to know how to save images as wallpapers, and there you go! You will have a wallpaper that suits your needs and preferences. Can I design desktop wallpapers? Yes, you can! You do not need to be a graphic designer for you to do this. That said, desktop wallpapers cannot be ignored, they mean different things to different people. Adding a quote will act as a reminder of what inspires you in your day-to-day life. Interesting, huh? You can add an image that shows how you feel or one that means something to you. Sometimes, people display their feelings through the use of desktop wallpapers. They add glamor to your computer and make it look aesthetically appealing and highly presentable. However, this element comes with a sense of beauty. In fact, you can decide to use a dark colour, and life will move on as usual. What is the use of a desktop wallpaper? Well, adding a wallpaper to your desktop is not mandatory. What you need to know is that these images that you add will neither increase nor decrease the speed of your computer. A desktop wallpaper is highly customizable, and you can give yours a personal touch by adding your images (including your photos from a camera) or download beautiful pictures from the internet. The background of this screen can be a single colour, multiple colours, or some other graphical representations. ![]() What is a desktop wallpaper? When you boot your computer, there is an initial screen that comes up, in which your folders, documents, and software shortcuts are placed. ![]()
