- Why Bother Looking for Gravitational Waves? 为什么要寻找引力波?
- The ripples are gravitational waves. 这些波动就是重力场波。
- They are likely sources of gravitational waves. 它们很有可能就是引力波源。
- When weather changes, baric meeting occurrence wave motion, affect the gravitational wave in atmosphere thereby. 当天气变化时,气压会出现波动,从而影响大气中的重力波。
- For a gravitational wave to be unambiguously identified, it must be detected by more than one instrument. 鉴于重力波显而易见的研究地位,必须投入更多的仪器来进行研究。
- Unfortunately, a passing gravitational wave will make only a tiny change in the distance the laser beams have to travel. 不幸的是,在激光束所经过的路程过程中,行经的重力波只会稍微地对干涉波波长稍微改变一点点。
- This is a systematic search of the sky, one location at a time, for any periodic gravitational wave coming from that location. 这是对天空的一次系统的搜索,目标是从某方向来的周期性的引力波,每次只分析一个方向。
- That is why gravitational waves are so difficult to detect! 这就是为什么引力波的探测如此困难的原因。
- These spacetime distortions travel as gravitational waves. 这些时空的改变以引力波的形式传递。
- GEO 600 is a gravitational wave observatory in Hanover, Germany built by an international collaboration of scientists from the UK and Germany. GEO 600是位于德国汉诺威的一个引力波观测站,由来自英德两国的科学家们合作建设而成。
- Then there are plans to examine the gravitational wave background, which would show what the universe looked like a fraction of a second after the Big Bang. 接下来的计划是检查引力波背景,这可以显示大爆炸后瞬间宇宙的样子。
- Most of the new gravitational wave detection projects are using laser interferometers instead of resonant mass detectors because they are more sensitive. 大多数引力波探测项目都是使用更为灵敏的激光干涉计探测仪而不是共振质量探测仪。
- A series of problems, gravitational wave, hypervelocity of light and others, concerned with physics in the study of astronomy actively in the past few years are also explored. 还探讨了近年来在天文学的研究中比较活跃的与物理有关的科题,如引力波,超光速等问题。
- The usual version of this common question goes something like: "Yesterday you said that LIGO has 4km arms and that a gravitational wave makes the arm length change a little because space is distorted. 这个问题的常见版本类似于:“昨天你们说LIGO的臂长为4公里,然后在引力波扭曲了空间后这个长度改变了一丁点。
- Ben Owen is an Assistant Professor of Physics at Penn State University. Much of his research involves gravitational wave physics. He is hoping to test his predictions with LIGO data. 欧文博士是宾州州立大学的助理教授。他的研究领域主要为引力波。他希望能够用LIGO的数据对他的预测进行检验。
- LIGO started collecting data in 2003. The observatory is the largest, most sensitive gravitational wave detector ever built. A planned series of upgrades will increase LIGO's sensitivity even more. LIGO从2003年开始收集数据。它是目前全世界最大的、灵敏度最高的引力波探测所。一系列的升级计划将更进一步提高其灵敏度。
- Supernovae remnants can leave behind pulsars or spinning neutron stars that may produce gravitational waves. 超新星遗迹中可能还存留有脉冲星或自旋中子星,而这些都会产生引力波。
- The GEO600 gravitational wave detector in Hanover, Germany, has not yet detected any gravitational waves. As a consolation prize, it may instead have uncovered the ultimate nature of reality. 在德国汉诺威的GEO600重力波探测器至今还没有检测到任何的重力波。庆幸的是,它却反而揭露了客观现实的终极属性。
- Binary systems that emit gravitational waves can be made of stars, black holes, or a combination of the two. 双星系统中的星体可以是恒星、黑洞或两者的组合。
- Weber claims recently to have observed gravitational waves coming from the centre of the galaxy. 最近,韦伯声称已观察到来自银河系中心的引力波。
