Can the wave function collapse before being measured?

[least_action]

N.B. I am not trying to send information back in time or generate infinite free energy (also I couldn't find how to delete the other thread but could a moderator please delete it for me)

If you could send classical information signals faster than light, then according to relativity you could communicate backwards in time.

The wave collapse for quantum entanglement travels faster than light. So can wave collapse happen to a quantum state caused by a future measurement or did I make a mistake? If it is true what does it imply?

This is your 3rd question about collapse...
Your next question will be about collapse before the very first measurement device was formed.
Just forget about the collapse...
It is completely misleading and obsolete concept

Too true.

Least Action... you're asking practical question about an abstract concept that is only useful as a mechanism in the formalism of QM... it probably has no physical reality. I can't tell if you're trying to understand retrocausality as in DCQE experiments, or if you're futzing around with time travel.
