What is Miller–Urey experiment?
The '''Miller–Urey experiment''' (or '''Urey–Miller experiment''') was an [[experiment]] that made [[organic compound]]s out of [[Inorganic compound]]s by applying a form of [[energy]].<ref name=Hill>{{cite journal |author=Hill H.G. & Nuth J.A. |title=The catalytic potential of cosmic dust: implications for prebiotic chemistry in the solar nebula and other protoplanetary systems |journal=Astrobiology |volume=3 |issue=2 |pages=291–304 |year=2003 |pmid=14577878 |doi=10.1089/153110703769016389|bibcode=2003AsBio...3..291H }}</ref><ref>{{cite journal | title=The analysis of comet mass spectrometric data | author=Balm S.P; Hare J.P. & Kroto H.W.| journal=Space Science Reviews| year=1991| volume=56| issue=1–2| pages=185–9 |doi=10.1007/BF00178408| bibcode=1991SSRv...56..185B| s2cid=123124418}}</ref> The idea was to simulate [[Hypothesis|hypothetical]] conditions thought to be present on the early [[Earth]] ([[Hadean]] or early [[Archaean]]). It was a test of [[abiogenesis| the chemical origins of life]]. Specifically, the experiment tested [[Alexander Oparin]]'s and [[J.B.S. Haldane]]'s hypothesis that conditions on the primitive Earth favored [[chemical reaction]]s that [[Synthesis|synthesize]]d organic compounds from inorganic precursors. Considered to be the classic experiment on the [[Abiogenesis|origin of life]], it was conducted in 1952 and published in 1953 by [[Stanley Miller]] and [[Harold Urey]] at the [[University of Chicago]].<ref>{{cite journal |last=Miller |first=Stanley L. |url=http://www.abenteuer-universum.de/pdf/miller_1953.pdf |title=Production of amino acids under possible primitive Earth conditions|journal=Science |year=1953 |volume=117 |pages=528–529 |doi=10.1126/science.117.3046.528 |pmid=13056598 |issue=3046|bibcode=1953Sci...117..528M }}</ref><ref>{{cite journal |title=Organic ccompound synthesis on the primitive Earth |url=https://archive.org/details/sim_science_1959-07-31_130_3370/page/n3 |journal=Science |year=1959 |volume=130 |pages=245–251 |doi=10.1126/science.130.3370.245 |pmid=13668555 |i
