Comparing the wavefunction of single and entangled particle

[lucas_]

Your reasoning escapes me.

The ignorance ensemble applies to QM and QFT. Quantum gravity, as the link I gave explains, is a perfectly good theory up to a cut-off. What's beyond the cut-off - who knows. It may necessitate a revision of the other stuff - but as of now there is no issue.

QM and QFT are just effective field theory.. their spacetime are fixed. In general relativistic quantum field theory, the fields interacts with geometry. So before wavefunction collapse or even EPR particle entanglements, won't the geometry be able to track the fields or particles while still in pure states?

Don't know that one - have you a paper?

And if you don't can we stick to conventional physics?

Thanks
