In science fiction, stasis or stasis field is a confined area of space where time has been stopped or the contents have been rendered motionless. ==Overview== A stasis field is a region where a stasis process is in effect. Stasis fields in fictional settings often have several common characteristics. These include infinite or near-infinite rigidity, making them "unbreakable objects", and a perfect or nearly-perfect reflective surface. Most science fiction plots rely on a physical device to establish this region. When the device is deactivated, the stasis field collapses; that is, the stasis effect ends. Time is often suspended in stasis fields. Such fields will thus have the additional property of protecting non-living materials from deterioration. This time dilation can be, from an in-universe perspective, absolute, so that something thrown into the field, has the field triggered, and after any length of time reactivated, would fly out as if nothing had happened. Storylines using such fields often have materials as well as living beings surviving thousands or millions of years beyond their normal lifetimes. This property also allows for such plot devices as booby traps, containing, for instance, a nuclear bomb. Once out of the stasis field the trap is sprung. In such a situation, it wouldn't do to let the protagonist see what is in the field, so in stories like this, the story line will not allow normal beings to see something protected by a stasis field. One use of stasis fields is as a form of suspended animation: to let passengers and cargoes (normally of spacecraft or sleeper ships) avoid having to experience extremely long periods of time by "skipping over" large sections of it. They may also be used (such as in The Night's Dawn Trilogy) as protection against the effects of extreme acceleration. There are real phenomena that cause time dilation similar to a stasis field's. Velocity near light speed or a powerful gravitational field will cause time to progress more slowly. However, there is no known theoretical way to cause such time dilation independent of these conditions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stasis (fiction)」の詳細全文を読む スポンサード リンク
