1. The grand unified theory of particle physics is applied to the supermassive stars, whose energy scale is large enough to take an infinitely collapsing process. A new model is proposed that after nucleon-decays, a supermassive star will convert nearly all its mass into energy, and become a lepton star that might possibly be substable or unstable.
在超重质量星无限塌缩的过程中，其能量标度达到足够大时，此时就可以应用粒子物理中的大统一理论，并提出一个新的模型：核子衰变后一个超重质量星将把它的几乎所有质量转化为能量，从而变为可能是亚稳定或不稳定的轻子星。
2. Conventional theory suggests that it must have formed like a star, from a collapsing cloud of interstellar gas.
传统的理论认为它一定像一颗恒星那样是有一团星际气体形成的压缩星云组成的。
3. A black hole is a massive star, which is collapsing inward at the speed of light.
黑洞是一个巨大的恒星，它以光的速度向内部塌陷。
4. The variation of the angle magnetic and rotation axes in a collapsing star cherishing time
晚期恒星坍缩时磁轴的变化规律
5. In some cases, the collapsing of a star produces a black hole.
有些情况下，恒星的塌缩会产生一个黑洞。

6. Actress Brittany Murphy, star of Hollywood films such as Clueless and8 Mile, has died at age32 after collapsing at home in Los Angeles.
好莱坞电影《独领风骚》和《8里公路》的主演，女演员布兰妮·墨菲猝死于洛杉矶家中，享年32岁。
