Our view of black holes has been limited to the electromagnetic radiation that the material falling into the black hole gives off. But this emitted light will have to travel on curved paths in order to reach our telescopes. As a result, our views of structures near black holes will be warped.
New observations by the The Event Horizon Telescope will be able to see distortions of space caused by black holes strong gravity.
Visible light is not the only form of electromagnetic radiation. In order to understand black holes, we have had to observe them using X-ray, ultraviolet, and radio telescopes.
Similarly, electromagnetic radiation is not the only type of radiation. When masses such as black holes move rapidly, gravitational radiation is emitted.
Modern technological advances allow scientists to see with a new kind of eyes. Once they don't see light but see the stretching and squeezing of space-time itself.
현대의 과학기술의 발전은 새로운 눈을 제공했는데, 빛을 보는것이 니라 시공간이 줄었다 늘었다 하는 모습을 관측할 수 있게 해준다.
By using gravity to probe into the heart of black holes, we can determine details that would otherwise be hidden behind the dust and gas of an accretion disk.
Gravitational waves predicted by Einstein have recently become the hot new tool to generate scientific data on the behaviors of black holes and compact objects in extreme orbits.
아인슈타인에 의해 예측되었던 중력파는 블랙홀에 관한 과학 정보를 수집하는 중요한 도구가 되었다. [중력파를 관측하여 블랙홀의 중요한 자료를 수집할 수 있게 되었다.] 아주 멀리 떨어진 곳에서 중력파를 검출 하게 됐다.
--------------------------------------------
In order to see a gravitational wave, there are a couple options: we can measure the influence of a passing wave on laser beams, or we could precisely time how the pulses of fast rotating pulsars change when a gravitational wave passes by.
중력파를 검출 하기 위한 몇가지 방법이 있는데, 중력파가 레이져 광선을 통과할 때 일으키는 미세한 변화를 검출하는 방법과 중력파가 빠르게 회전하는 펄서를 지날 때 일으키는 변화를 측정하는 방법이다.
Let's start with the simplest way the black hole's gravity effects are observations. Gravitational lensing.
