:: Einstein proved right on gravity

"The speed of gravity has been measured for the first time, revealing that it does indeed travel at the speed of light."BBC News - Einstein proved right on gravity

Something quite exciting about this measurement, perhaps an echo of the excitement felt when Einstein's first thoughts on the subject were presented early in the last century. While there are countless parallels in math and physics between the mechanical and electrical worlds, it is the mundane mechanical aspects of our physicality that in the end thwart much of the potential hinted by electronics. The uses of light, of electronics, cannot exist without the mechanical material to transport it. The failure of your computer is almost always a bad solder joint, a flexure failure, material fatigue, something mechanical. The electrons themselves rarely fail! It is gravity that underpins our mechanical world, much like the speed of light is a foundation for all things electrical. The major implications of this relationship are in the large distances and massive objects of space. Nevertheless, this startling concept, linking gravity and light, is truly profound. Perhaps in ways that in the end will be far more mundane than its current focus fixed in grandeur of the cosmos. Fruition of the search to "prove" it has taken nearly a century since Einstein's proposal in 1915 and is but a baby step to where the General Theory of Relativity will lead. Bravo!
