To pin down relativistic frame dragging, researchers included data on Earth's uneven gravity field, shown in this map by NASA's GRACE satellite. Fluctuations owe to mountains, trenches, and unseen subsurface density differences. Red indicates high gravity; blue areas have low gravity. 어휘연구 pin down ~에게 자세한 설명을 요구하다, 사실 등을 밝히다, 분명히 설명하다 frame 틀, 뼈대, 구조, 구성, 체제 uneven 평탄하지 않은, 고르지 못한, 울퉁불퉁한 Fluctuation 변동, 오르내림, 파동 trenches 참호, 도랑, 해자, 해구, 협곡 상대적인 틀의 잡아당김(중력)을 보여주기 위하여, 과학자들은 나사의 그레이스 인공위성에 위한 이 지도에서 보여준 지구의 일정하지 않은 중력장에 대한 자료를 포함시켰다. 색의 변화들은 다른 밀도를 가진 산맥들, 협곡들 그리고 보이지 않는 표면에 의한 것이다. 붉은 색은 높은 중력을 나타내고 푸른 지역들은 낮은 중력을 갖고 있다.

It is a modification to the simpler aspects of gravity set out by Newton. Working from Einstein's relativity theory, Austrian physicists Joseph Lense and Hans Thirring predicted frame dragging in 1918. (It is also known as the Lense-Thirring effect.) 어휘연구 Frame dragging 판을 잡아당김 modification 수정, 변경 set out 세우다, 설립하다 Here's how it works: Any object with mass warps the space-time around it, in much the same way as a heavy object deforms a stretched elastic sheet, explained study leader Ignazio Ciufolini of the Università di Lecce in Italy. 어휘연구 mass 질량 deform 변형시키다, 불구로 만들다 elastic 탄력성의, 탄력적인 If the object spins, another distortion is introduced, "in the same way as the elastic sheet would be twisted by a spinning heavy wheel on it." 어휘연구 distortion 찌그러짐, 뒤틀림, 만곡 wheel 바퀴, 수레바퀴 If the space around Earth is being frame-dragged, then satellites ought to be caught up in the deformation, scientists reasoned. Imagine how a second object on the elastic sheet would be moved by the scrunching motion created as the sheet is deformed. 어휘연구 satellite 인공위성 deformation 변형, 뒤틀림, 왜곡 scrunching 헝클어진 scrunch 헝클어 보이도록하다
