force-field
Invisible protective bubble
A force-field is a barrier of energy, typically invisible, that protects or contains something.
The concept originates in science fiction, where force-fields deflect weapons, seal airlocks, or imprison characters.
In physics, force field (usually unhyphenated) refers to a region where a force like gravity or electromagnetism acts on objects.
Figuratively, someone might seem to have a force-field around them if they appear emotionally impenetrable or unapproachable: She had a force-field up that kept everyone at a distance.
