How do particles become entangled?

Click For Summary
Particles become entangled through interactions, often described as a "bump," which can occur during collisions or other forms of interaction. The process involves a transformation of their quantum states, where the initial separate states combine into a superposition of entangled states. For example, in a collision, the conservation of momentum leads to correlations between the particles, resulting in entanglement. The specifics of how this occurs depend on the nature of the interaction and the particles involved, but it is fundamentally tied to quantum mechanics principles. Understanding this mechanism is crucial for exploring concepts like decoherence and the measurement problem in quantum physics.

MWI.
Actually I think using a “Ball” is an ok analogy as long as it isn’t performing any impossible tests on itself, like trying to decide if it’s really dead or not! Better than “Schrodinger's cat” anyway.

Looked in other parts of thread but couldn’t find MWI defined. What is MWI-like?
EDIT: Think I found it --- from MWT to "Immortality"
Not so we'd ever know.
