As they explain in their study, local realism consists of both realism – the view that reality exists with definite properties even when not being observed – and locality – the view that an object can only be influenced by its immediate surroundings.

An interesting article about quantum mechanics and realism:

Physicists close two loopholes while violating local realism

An interesting quote from the article:


So if local realism can be violated, this means reality is only probability, and becomes real as we understand it only when observed?
