With respect to life, the origin of homochirality on Earth has been the greatest mystery because life cannot exist without molecular asymmetry. Many scientists have proposed several possible hypotheses to answer this long-standing L-D question. Previously, Martin Gardner raised the question about mirror symmetry and broken mirror symmetry in terms of the homochirality question in his monographs (1964 and 1990). Possible scenarios for the L-D issue can be categorized into (i) Earth and exoterrestrial origins, (ii) by-chance and necessity mechanisms, and (iii) mirror-symmetrical and non-mirror-symmetrical forces as physical and chemical origins. These scenarios should involve further great amplification mechanisms, enabling a pure L- or D-world. 610 $asupramolecular assembly 610 $aweak neutral current 610 $ahomochiral and heterochiral aggregates 610 $avortex 610 $aneutrinos 610 $aSoai reaction 610 $aViedma ripening effect 610 $anucleus?molecular coupling 610 $aabsolute asymmetric synthesis 610 $acircular dichroism 610 $aenantiomer self-disproportionation 610 $amagmatic flow 610 $ametal-organic framework 610 $aZ0 boson 610 $ahidden chirality 610 $agravitation 610 $aSDE 610 $aetch figures 610 $areplicators 610 $asupramolecular chirality 610 $aderacemization 610 $aassemblies 610 $aspin polarized electrons 610 $asuper-high-velocity impact 610 $ahomochirality 610 $achirogenesis 610 $aheat capacity 610 $atunneling 610 $aprebiotic 610 $aSalam hypothesis 610 $atilt-chirality 610 $aself-assembly 610 $aracemic field 610 $atriethylenediamine (DABCO) molecules 610 $aenvironmental chirality 610 $abioorganic homochirality 610 $apolymer 610 $aenantioselective reaction 610 $atwo-fold helix 610 $aorigin of life 610 $abiological homochirality 610 $aparity violation in the weak interaction 610 $aamino acids 610 $amulti-point approximation 610 $amagnetism 610 $aC1- and C2-symmetric catalysts 610 $aspin-polarized lepton 610 $alipid 610 $achiral field (memory) 610 $aWallach?s rule 610 $aasymmetric autocatalysis 610 $aplasma reactor 610 $acircularly polarized photon 610 $aasymmetric reaction 610 $aracemate 610 $aenantiomorphism 610 $asymmetry breaking 610 $a?-strand 610 $achirality 610 $acircularly polarized light 610 $acircularly polarized luminescence 610 $aautocatalysis 610 $aamino acid handedness 610 $aasymmetric synthesis 610 $aprecision measurement 610 $anepheline 610 $achiral separation 610 $aparity violation 610 $aachiral stationary phase 610 $agenesis of life chirality 610 $ahigh dimensional chirality 700 $aFujiki$b Michiya$4auth$01324888 906 $aBOOK 912 $a9910367746203321 996 $aPossible Scenarios for Homochirality on Earth$93036443 997 $aUNINA
