Physicists led by [[David Kaiser (physicist)|David Kaiser]] of the [[Massachusetts Institute of Technology]] and Anton Zeilinger of the [[Institute for Quantum Optics and Quantum Information]] and [[University of Vienna]] performed an experiment that "produced results consistent with nonlocality" by measuring starlight that had taken 600 years to travel to Earth.<ref>{{Cite journal|title=Synopsis: Cosmic Test of Quantum Mechanics |journal=Physical Review Letters |volume=118 |issue=6 |pages = 060401|date=2017-02-07 |doi=10.1103/PhysRevLett.118.060401 |pmid=28234500 |last1=Handsteiner |first1=Johannes |last2=Friedman |first2=Andrew S |last3=Rauch |first3=Dominik |last4=Gallicchio |first4=Jason |last5=Liu |first5=Bo |last6=Hosp |first6=Hannes |last7=Kofler |first7=Johannes |last8=Bricher |first8=David |last9=Fink |first9=Matthias |last10=Leung |first10=Calvin |last11=Mark |first11=Anthony |last12=Nguyen |first12=Hien T |last13=Sanders |first13=Isabella |last14=Steinlechner |first14=Fabian |last15=Ursin |first15=Rupert |last16=Wengerowsky |first16=Sören |last17=Guth |first17=Alan H |last18=Kaiser |first18=David I |last19=Scheidl |first19=Thomas |last20=Zeilinger |first20=Anton |arxiv=1611.06985 |bibcode=2017PhRvL.118f0401H |s2cid=4607466 }}</ref> The experiment “represents the first experiment to dramatically limit the space-time region in which hidden variables could be relevant.”<ref>{{Cite journal|last=Handsteiner|first=Johannes|date=2017-01-01|title=Cosmic Bell Test: Measurement Settings from Milky Way Stars|journal=Physical Review Letters|volume=118|issue=6|pages=060401|doi=10.1103/PhysRevLett.118.060401|pmid=28234500|bibcode=2017PhRvL.118f0401H|arxiv = 1611.06985 |s2cid=4607466 }}</ref><ref>{{Cite web|url=https://www.quantamagazine.org/20170207-bell-test-quantum-loophole/|title=Experiment Reaffirms Quantum Weirdness |work=[[Quanta Magazine]] |last=Wolchover|first=Natalie |author-link=Natalie Wolchover |language=en-US |access-date=2020-02-08 |date=2017-02-07}}</ref><ref>{{Cite journal|title=Cosmic experiment is closing another Bell test loophole |language=en|doi=10.1063/pt.5.2051|journal=Physics Today|year=2016}}</ref>
