An exotic particle is a kind of theoretical particle said to exist by some areas of modern physics, and whose alleged properties are extremely unusual. The best-known example is probably the tachyon, a hypothetical particle that always travels faster than light.〔 〕〔 〕 Another example of this is supersymmetry, a theoretical set of significantly heavier versions of known particles (this is also one of the proposed candidates for dark matter). 〔 〕 Exotic particles are frequently featured in science fiction, either those with real-world academic backing, or entirely fictional. ==References== 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「exotic particle」の詳細全文を読む スポンサード リンク
