This isn&#x27;t really more &quot;macroscopically quantum&quot; than spectroscopy or the stability of matter.  (Neither of those would be possible in a normal classical universe either.)  You&#x27;re just noticing indirect quantum effects on large scales, but there is no macroscopic coherence.<p>On the other hand, the interferometery experiments like MAQRO discussed in the article do actually exhibit long-range coherence of large amounts of matter.
