Letter: The idea of classical reality has long been upended

From Dave Rowsell, Gowerton, Swansea, UK

I agree with Daniele Oriti that “we have to embrace the fact that we make reality”, and note readers’ responses. We need to keep in mind that relativity and quantum physics have comprehensively undermined our classical, or Newtonian, view of reality (12 October, p 40, and Letters, 2 November).

For instance, we seem to be increasingly understanding space-time as emergent, rather than some given backdrop to the “things” around us, including you and me. Maybe, too, we should examine what we mean by “objectivity”.

Could it be that each of us is, in some sense, the entire universe aware of itself, and that we are all (animals and possibly plants as well) in some kind of quantum superposition with one another? Answers on a postcard please.
