The article discusses the concept of chirality in relation to life forms and elementary particles, emphasizing its implications in science. It highlights the caution advised by scientists regarding the creation of mirror-image life due to potential immune evasion. Historically, chirality was connected to light behavior, with Fresnel's discoveries leading to modern understandings of chirality as an essential property of all particles. The article details how massive particles have complex chirality behaviors influenced by speed and quantum properties, illustrating the intricate relationship between particle physics and the concept of handedness.
Kitty couldn't have digested looking-glass milk. Worse, if it had contained any bacteria with the opposite handedness, her immune system and antibiotics would have been ill suited to put up a fight. A group of prominent scientists recently cautioned against the synthesis of mirror-image lifeforms for this reason-if any were to escape the lab, they could evade regular lifeforms' defense mechanisms.
Nowadays, physicists consider chirality a fundamental property of all elementary particles, just like charge or mass. The particles that don't have mass are always traveling at the speed of light, and they also all carry an intrinsic angular momentum as though they're spinning like a top.
