速逃星 的英文怎麼說
中文拼音 [sùtáoxīng]
速逃星
英文
runaway star-
Because of gravitational attraction, the escape velocity at the surface of a star, say, will be higher if the star is smaller in size or heavier
恆星質量越大，體積越小，引力的羈絆便越大，所需逃逸速度亦越高。On the other hand, einstein discovered that the maximum velocity of any object is the speed of light. therefore, if the escape velocity on the surface of an object is greater than the speed of light, then nothing, including light, can escape from it
另一方面，愛恩斯坦的相對論斷言宇宙中最高的速度便是光速，所以如所需的逃逸速度大於光速，那麼宇宙中包括光在內的一切都不可能逃離引力的魔掌，這顆恆星便成為Data from existing x - ray satellites that show images of gas whizzing about black holes at close to the speed of light hint that time slows as the gas plunges into the zone from which escape is impossible
從現有的x射線衛星傳回的數據顯示，氣體以接近光速的速度呼嘯著被吸入黑洞，這暗示當氣體進入這個不可逃逸的空間時，時間慢了下來。Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole
黑洞是一種星體，密度非常之大，就連光也逃離不了它的重力吸引，既然沒什麼東西比光速更快，所以在黑洞中沒有物質能從它裏面逃逸出來。分享友人
