  3. There is a positive observational and theoretical basis for believing that neutron stars and black holes follow as a result of supernovae.

  4. All black holes are formed from the gravitational collapse of a star, usually having a great, massive, core

    所有的黑洞都是因為恆星的引力坍縮而形成，這種恆星通常有一顆巨大而厚重的核心。
  5. General relativity ( as well as most other metric theories of gravity ) not only says that black holes can exist, but in fact predicts that they will be formed in nature whenever a sufficient amount of mass gets packed in a given region of space, through a process called gravitational collapse

    廣義相對論（以及很多其它的米制引力理論）不只是說黑洞可以存在，而是事實上預言了它們將會自然形成只要在給出的空間區域質量聚集到足夠大，雖然過程稱做引力坍塌。
  6. However, it is impossible for astronomers to see the even horizon directly due to the current technical limitation. therefore what scientists discovered so far is only an indirect evidence of the gravitational redshift or similar phenomenon caused by black holes. but those results undoubtedly become an important bridge for linking black hole theory with actual observation

    雖然目前的觀測技術尚未允許我們直接看到黑洞的視界，所以有關黑洞產生的重力紅移或者類似的觀測結果都不是決定性的，但這些結果無疑會成為連系黑洞理論和實際觀測的重要橋梁。
  7. Black holes can be seen via the death throes of the matter being sucked in

    經由正被吸引物質死亡陣痛能看見黑洞。
  8. The position of the second order phase transition points for the stationary black holes has been argued by many authors recently

    穩態黑洞在什麼條件下出現二級相變，近年來在引力學界存在著爭論。
  9. Some speculation exists that quasars are actually white holes instead of supermassive black holes

    一些人推測存在的類星體實際上是白洞而不是超大質量的黑洞。
  10. Other speculations include the hypothesis that quasars are actually white holes instead of supermassive black holes

    其它的推測包括類星體實際上是白洞而不是超大質量黑洞的假設。
  11. Do white holes exist ? if so, how are they formed ? does time exist in white holes, since they are inverse black holes

    白洞存在嗎？如果存在的話它們都怎麼形成的？時間在白洞裏面是否仍然有效，既然它們和黑洞是相反的？
  12. The existence of black holes in the universe is well supported by astronomical observation, particularly from studying supernovae and x - ray emissions from active galactic nuclei

    天文學觀察很好地支持了宇宙中黑洞存在，特別從研究來自活躍的銀河核心超新星和x光輻射。

  14. Since black holes do not classically emit radiation, the thermodynamic viewpoint was simply an analogy

    既然黑洞不是經典地發出輻射，熵的觀點只是一個類推。
  15. Black holes are some of the most mysterious objects of the universe. a mere mention of the name invokes a sense of enormous cosmic power at work

    黑洞是宇宙中最神秘的物體之一，只要提及黑洞這個名稱，便會使人聯想到宇宙中強大的力量，難怪它成為科幻電影常常描寫的對象。
  16. Astronomers are almost sure that the dark companions of many x - ray binaries are black holes and not neutron stars. v404 cygni is one of the most well - known examples

    天文學家已經幾乎可以肯定很多x射線雙星所包含的黑暗天體是黑洞而非中子星，其中最著名的例子包括天鵝座v404等。
  17. We fhd that the energies have the following important properties : ( 1 ) the energies are positive and monoton - ically decrease to their arnowitt - deser - misner ( adm ) masses at spatial infinity ; ( 2 ) the energies have the correct newtionial limiting, and include the binding energies from the gravitation ^ electrostatic charge and dilaton charge, respectively ; ( 3 ) martinez ' s conjecture is valid for such black holes

    結果表明該能量具有如下幾個重要特徵： （ 1 ）該能量是正定的，且隨徑向坐標單調遞減，在無窮遠處為黑洞的adm質量； （ 2 ）該能量具有正確的牛頓極限，並包含有分別來自於引力、靜電荷和伸縮子荷的束縛能； （ 3 ） martinez猜測對這些黑洞依舊成立。

    另一種有星系質量大小的黑洞常發現存在於活躍的星系核心（ agn ） 。
  20. Candidates for more massive black holes were first provided by the active galactic nuclei and quasars, discovered by radioastronomers in the 1960s

    活躍的銀河核和類星體首先提供了更多質量龐大的黑洞候選者，在1960年無線天文學家發現了它們。
