- Can Ring Galaxies Form by Gravitational Collapse? 引力坍缩能形成环星系吗?
- All black holes are formed from the gravitational collapse of a star,usually having a great,massive core. 所有的黑洞都是因为恒星的引力坍缩而形成,这种恒星通常有一颗巨大而厚重的核心。
- BE A supernovais a massive star that undergoes a gravitational collapse, then a gigantic explosion, blasting away the outer layers into space. 是一种巨大的恒星,它不断进行着引力的收缩,然后就会发生巨大的爆炸,而它的外层会随着爆炸产生的巨大气流被吹向外太空。
- If it had been slightly more dense, it might have undergone gravitational collapse, just like the matter falling into a black hole. 假如它的密度比临界密度再高一些,将会导致重力塌缩,就像掉入黑洞的物质一样。
- If the singularities that formed in the gravitational collapse of a massive star are visible to external observers, they could provide a laboratory to study quantum-gravitational effects. 假如在大质量恒星重力坍塌时形成了外界可见的奇异点,它们可用来做为研究量子重力效应的实验室。
- Both mechanisms reduce an entire star to a shell of gaseous debris, and gravitational collapse events also leave behind a hyperdense neutron star or, in extreme cases, a black hole. 这两类机制都把整个恒星缩减成气壳状的碎片,而且重力塌缩事件会遗留下密度超高的中子星,在一些比较极端的状况下,甚至会留下黑洞。
