They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射，發現其中兩組數據顯示，輻射脈沖的周期隨時間縮短，而其強度則隨時間衰減至消失，這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉，放出的輻射因為重力紅移而衰減的情況相符。
