Mirror life (also called mirror-image life) is a hypothetical form of life with mirror-reflected molecular building blocks.[1][2][3][4][5] The possibility of mirror life was first discussed by Louis Pasteur.[6] Although this alternative life form has not been discovered in nature, efforts to build a mirror-image version of biology's molecular machinery are already underway.[7]
