在 Doctor Who Season 5 故事情節期間，宇宙中的裂縫吸收了生物數量，從時間上完全刪除它們：
Amy Pond的母親和父親。 軍事神職人員Phillip，Crispin，Pedro和Marco參與“肉體與石頭” 哭泣的天使。 com/wiki/FleshandStone“rel =”nofollow noreferrer“>”Flesh and Stone“。 Rory在“冷血”中的屍體。 另外，顯然，鴨塘中的鴨子。 ;）
Amy Pond, who had a crack in her room for years but never got absorbed by it, even though her parents did. The Doctor, who reached into a crack to pull out a piece of the exploding TARDIS in "Cold Blood". Prisoner Zero, who was able to escape prison by fleeing into Amy's house through the crack in her wall. An Atraxi, who was peering at the Doctor and Amy through the crack in her wall in "The Eleventh Hour". The Saturnynians, who fled their damaged world for Earth through a crack in "The Vampires of Venice".
The answer from abcooper makes a very good point that didn't dawn on me: that the cracks can separately exhibit spatial or temporal properties. It then reminded me of something Angel Bob said in the episode "Flesh and Stone":
Being an exceedingly complicated space/time event (and a Lord of Time) makes the Doctor able to get near an "active" temporal rift for at least a short period of time without being absorbed by it, allowing him to reach into one in "Cold Blood", suffering some pain in the process. However, he is absorbed and erased from time when he ultimately plunges himself directly into the time explosion in "The Big Bang". When the crack first appeared in Amy's home, it absorbed her parents (and maybe other things) then went "dormant", transitioning to a spatial rift. This allowed Amy to remain near it without being erased from time, although small amounts of residual time energy may have been leaking through that affected her. Later, Prisoner Zero was able to escape through the crack, and the Doctor was able to force it open to communicate with the Atraxi on the other side. The crack that appears in the Byzantium seems much more powerful, requiring that it absorb more "complicated space/time events" to close it. After absorbing some soldiers and all of the Weeping Angels it transitions to a dormant state.
In "The Vampires of Venice", the Saturnynian Rosanna Calvierri says:
There were cracks. Some were tiny... some were as big as the sky. Through some we saw worlds and people and through others we saw silence... and the end of all things. We fled to an ocean like ours and the crack snapped shut behind us... and Saturnyne was lost.
The cracks that appeared presumably absorbed and destroyed much of the planet, transitioning to spatial rifts which allowed a small group to flee through them to Earth.
