(1.)

**Are uncertainty and entanglement linked together**? Are the eigenstates of an observable entangled since a measurement of one of them collapses the wavefunction to a single eigenstate, making all the coefficients of the other eigenstates 0?

(2.) Consider a very sensitive measuring tool that measures the spin of one of two spin-entangled electrons (their total momentum is 0).

**Is the entanglement of one of the electrons then transferred to the measuring device**(now the measuring device is entangled with the other electron) assuming the wavefunction does not collapse yet?

(3.)

**In general, is the entanglement transferred until the wavefunction collapses?**Does the wavefunction collapsing transform/transfer any uncertainty?

(4.) Is it possible to create a device that can measure states of a particle based on gravitational interactions? Assuming all particles make a measurement when they interact,

**what keeps massive particles from continuously collapsing from continuously interacting with other massive particles**, also assuming gravity is continuous? With other forces assuming they're continuously interacting?

__My thoughts:__Interactions do not necessarily cause wavefunction collapse. In the case that they do not, there is some form of entanglement transfer.

Thanks!
