How can we check whether or not gravity is quantum?

Although physicists have competing concepts of what quantum gravity could possibly be like, they’ve but to definitively decide whether or not the gravity that we expertise is quantum in any respect. A brand new proposal lays out a solution to dispute or affirm this by observing whether or not a quantum object’s state is affected when its gravity is measured.
Physicists have repeatedly proven that tiny objects are topic to quantum results, however for giant objects whose behaviour is very affected by gravity – with black holes being essentially the most excessive instance – the identical…
