What is the next major breakthrough after gravitational waves are discovered 如果再回到从前原唱

What is the next major breakthrough after gravitational waves are discovered? What is the next major breakthrough in human science after the discovery of gravitational waves? Some scientists and the media began to focus their attention on another mystery: dark matter. British astronomer Carlos Frenk believes that compared to the gravitational waves, that dark matter will be more important". Dark matter is compared to "dark clouds in the sky of physics in twenty-first Century", and many countries around the world are doing relevant research at present, while the successful detection of gravitational waves has encouraged the dark matter hunters. [] searched to no avail now see human bodies, such as the sun or light, or reflective, like the moon. According to the official website of the European Organization for nuclear research, dark matter is a kind of invisible material that is widespread in the universe. It does not work with electromagnetic force, in other words, does not absorb or reflect light, nor does it emit light. By gravitational effect, scientists estimate that 27% of the universe is made up of dark matter, 5 times more than the total mass of all visible stars and galaxies. For dark matter, physicists looking for many years, but always hard to find. Physicist Alex Murphy and his team are working on the big underground xenon experiment (LUX), about 14 miles below the site of an abandoned gold mine in South Dakota, the Guardian newspaper reported. This team has the most sensitive dark matter detector in the world. Physicists cooled a container filled with 1/3 tons of liquid xenon to about 101 degrees Celsius below zero. If the xenon atoms collide with the dark matter particles, the faint light produced will be captured by the detector. However, the probability of collision is minimal. Alex Murphy said, "it hasn’t happened yet."". The reason physicists believe in dark matter is that astronomers can detect the gravitational pull of dark matter on stars and galaxies. They think that dark matter is made up of weakly interacting massive particles, which are created in the big bang, passing through ordinary matter without leaving any trace, except gravity. Or will it break through? In the next few years, the large underground xenon experiment (LUX) will be upgraded completely, renamed LUX-Zeplin, and 10 tons of liquid xenon will be obtained. Alex Murphy said, "controlling 10 tons of liquid xenon in a mile underground is not a problem, because it’s very expensive, and it’s dangerous to freeze it at low temperatures."." Murphy believes that the technical difficulties mean that it may not wait until 2018 to produce results. In fact, the large underground xenon experiment (LUX) is not the only hunter to capture dark matter". In Australia, another team has placed the world’s most advanced dark matter detector in an underground gold mine. In outer space, the international space station is installing detectors, trying to capture dark matter signs in outer space. On 2015 12, China’s dark matter particle exploration satellite "Wukong" launched, the satellite successfully entered the scheduled transfer orbit. "Wukong" is the current observation in the world

发现引力波后 人类下一个重大突破是什么?   发现引力波之后,人类科学研究下一个重大突破会是什么?   一些科学家和媒体开始将目光瞄准了另一个待解谜团:暗物质。英国宇宙学家卡洛斯・弗伦克认为,“比起引力波,发现暗物质将更为重要”。   暗物质被比作“笼罩在21世纪物理学天空中的乌云”,当前世界多国都在进行相关研究,而引力波的成功探测更是让暗物质“猎手们”倍受鼓舞。   【苦寻无果】   现在人类所看到的天体,要么发光,如太阳;要么反光,如月亮。   根据欧洲核子研究组织官网介绍,暗物质是一种宇宙中广泛存在的不可见物质。它与电磁力不发生作用,换句话说,不吸收、不反射光,本身也不发光。   通过引力效应,科学家估计宇宙的27%是由暗物质组成,是所有可见星球、星系总和质量的5倍多。   对于暗物质,物理学家苦寻多年,却始终难觅踪迹。   英国《卫报》14日报道,物理学家亚历克斯・墨菲和他的团队正在进行“大型地下氙实验(LUX)”,地点位于美国南达科他州一座废弃金矿地下约一英里处。   这一实验团队拥有世界上最灵敏的暗物质探测器。物理学家将充满三分之一吨液态氙的容器冷却到约零下101摄氏度。如果氙原子同暗物质粒子发生碰撞,产生出的微光将会被探测器捕捉到。   然而,发生碰撞的几率微乎其微。亚历克斯・墨菲说,“至今还没有出现过”。   物理学家之所以如此相信暗物质的存在,是因为天文学家能够探测到暗物质作用在星球和星系上的引力。   他们认为暗物质由弱相互作用大质量粒子构成,它在大爆炸中被创造出来,在普通物质中穿行,没有留下任何痕迹,除了引力。   【或将突破?】   今后几年,大型地下氙实验(LUX)将全面升级,更名为LUX-Zeplin,并获得10吨液态氙。   亚历克斯・墨菲说,“在一英里的地下控制好10吨液态氙,不容有失,因为(它)非常昂贵,而且低温冷冻的气体会十分危险。”   墨菲认为,技术难点意味着可能要等到2018年才有望出结果。   实际上,大型地下氙实验(LUX)并不是唯一一个捕捉暗物质的“猎手”。   在澳大利亚,另一支团队也在一座地下金矿安置了世界最先进的暗物质探测器。   在外太空,国际空间站正在安装探测器,试图在外太空捕捉到暗物质迹象。   2015年12日,中国暗物质粒子探测卫星“悟空”发射升空,卫星顺利进入预定转移轨道。“悟空”是目前世界上观测能段范围最宽、能量分辨率最优的暗物质粒子探测卫星,超过国际上所有同类探测器。它将在太空中开展高能电子及高能伽马射线探测任务,探寻暗物质存在的证据,研究暗物质特性与空间分布规律。   《卫报》认为,人类对宇宙的探索永无止尽,许多待解之谜需要人类破解。亚历克斯・墨菲也认为,比起找到暗物质,更大的探索还在后面。   “暗物质像一把钥匙,能够打开物理学更深层次理论的大门。而这将是漫长的探索。”(陈丹)(新华社专特稿)相关的主题文章:
