新浪科技讯 北京时间1月9日消息,据国外媒体报道,2015年9月14日,美国中部标准时间凌晨3点50分,一丝微小的振动传递到了美国路易斯安那州利文斯顿的一台大型机器的4公里长臂上。极短的时间之后,同样的振动出现在了华盛顿州汉福德另一台同类机器的长臂上。最终,物理学家证实了这两个振动信号的本质:经过一个世纪的努力工作,科学家终于见到了引力波。他们发现,这些微小的振动来源于15亿年前两个黑洞的相互碰撞。
就在两个月之后,激光干涉引力波天文台(LIGO)就第二次探测到了引力波。然后,在2017年,物理学家又第三次、第四次、第五次和第六次探测到了引力波。利用这些探测结果,他们解决了物理学中一个长期悬而未决的谜题,证实了引力遵循着爱因斯坦的广义相对论。2017年10月,3位引力波研究的先驱者――巴里・巴里什(Barry Barish)、基普・索恩(Kip…

Particles Accelerated Due to Radiation Belt Around Earth
Particle accelerators are one example of the extreme engineering that we are capable of. However, rarely do we see something in nature that can accomplish the same goals as these marvels of modern science. The latest example of something like this being discovered comes from probes studying the Earth’s magnetic field. The probes have found electrons traveling close to the speed of light. This…

Filters are designed to get accurate experimental results by removing impurities and unwanted particles. PVDF syringe filters (polyvinyl fluorocarbons) or other non-toxic polyfluid acid filters (PVDF) are needed to remove particles with a diameter of 0-45um larger than particles with a diameter of 1.5-5 mm.
