Getty ImagesMark Garlick/Science Photo Library Gravity is a bit of an enigma. We know how it works, but not really what causes it. In 1915, Einstein’s famous Theory of Relativity demonstrated that gravitational attraction is due to the warping of space: Large masses like stars and planets actually curve the space around them, pulling other objects in. Advertisement - Continue Reading Below But exactly how space gets curved is still an open question. One possibility is that the force of gravity is carried by a particle, like how electricity is carried by the electron or how light is carried by the photon. This hypothetical particle has been dubbed the graviton, but there’s no guarantee that the graviton exists at all.If it does, however, finding it could help solve one of the biggest problems in physics and unify gravity with quantum mechanics. The two biggest discoveries of the 20th century have resisted all attempts by physicists to combine them into one grand … [Read more...] about Scientists Propose an Experiment to Detect the Shadow of a Graviton
This random Legendary drop is a great rocket launcher that’s easy to miss. It deals heavy damage to a big area, making it great for crowds and boss enemies alike. In rocket launchers, blast radius and projectile velocity are the most important stats, and Curtain Call is strong on both fronts. It also reloads pretty fast, allowing you to get you firing as quickly as possible.The big benefit of Curtain Call, however, is that, along with its big explosions and fast rockets, it launches cluster bombs upon impact, which fly out from the shell and explode around it. This wreaks havoc on large areas, and is almost like adding a second rocket to your shot. Curtain Call is great for taking down scores of enemies or making an entire team of Guardians very sad in the Crucible, especially in game modes like Control where teams tend to bunch up.If you like lightning, you’ll love Riskrunner, which comes from random Exotic drops. The submachine gun fires fast and is great against … [Read more...] about The 20 best weapons in ‘Destiny 2,’ and where to find them
After weeks of teasing, Blizzard has finally announced its 24th Overwatch hero, Orisa. As the sixth tank, she is specifically designed to act as the central anchor of her team.According to her background, Orisa is a four-legged robot that was designed by an incredibly smart 11-year-old engineer named Efi Oladel. Her main function is to keep peace in Numbani, a task to which she is immensely dedicated. In both real life and Overwatch lore, Orisa is the newest hero. What she lacks in experience, she makes up for in power.Orisa’s main weapon is the Fusion Driver, a a rapid-fire automatic gun with high range and accuracy. To keep her balanced, her movement is slowed down while she is firing. As an alternative firing option, Orisa can use “Halt!” In this technique, a graviton charge is launched across the map, slowing nearby enemies in its trail, then pulling them toward its detonation point.Defensively, Orisa can also use Fortify to reduce the damage … [Read more...] about Holding out for a hero?

Data Analysis World on a StringToward experimental support for string theoryBill Weaver, Ph.D.Download / Listen to an Audio Intro from Bill Weaver.A while back, learned philosophers plied their trade by mixing various combinations of the four primary elements of Earth, Air, Fire and Water. Around the same A Toroidal LHC Apparatus (ATLAS) is one of six particle detector experiments currently being assembled in the Large Hadron Collider at CERN. time, healers knew that discomfort was brought about by bad vapors that were inhaled in the company of the sick or the morally unfit. In the 1600s, some malcontents suggested the existence of minuscule particles that came in many more flavors than the four basic elements and also dreamed up the heretical notion that discomfort and disease may be caused by tiny seed-like particles called “germs.” These wild speculations were broadly ridiculed while, at the same time, contritely praised for offering explanations based on invisible … [Read more...] about World on a String.
