The Entanglement

[Ignat]

Another interesting thing in quantum physics is entanglement, which is as fabulous as superposition.
The Entanglement in quantum physics is a phenomenon in which the quantum states of two or more particles become so closely related that the state of one particle cannot be fully described independently of the state of the other, even if the particles are located at a great distance from each other. A key aspect of entanglement is non-locality: a change in the state of one entangled particle instantly affects the state of another, regardless of the distance between them. This violates the classical concepts of locality and causality.Quantum entanglement states that particles can be instantly connected to each other, regardless of distance. This contradicts the classical notion of locality, according to which interactions between objects occur through intermediaries, such as fields or particles, and depend on the speed of light.
The statement that particles can be connected and influence each other is not objectionable. Indeed, in any system, its constituent parts can interact. However, they can only influence each other within the system. So interaction at a distance exceeding the boundaries of the system is closer to a fairy tale than to science.

if i had to distill this to one point, it appears to be the 'instantaneous' part that is the issue? meaning once two objects are further apart than the speed of light they shouldn't be able to interact 'instantaneously', which would require communicating faster than the speed of light. am i correctly summing that up?

I've noticed that not many bring up heat when discussing entanglement. Entanglement is tenuous, as something as basic as heat will disrupt the entanglement. What other forces disrupt it? Entanglement is sometimes portrayed as some kind of super power, but isn't it really a rare and special state that is easily altered?

how can it be proven that particles exist in multiple states simultaneously? any measurement proves otherwise. It's more likely that when it's said that one particle "instantly affects the state of another" the truth of the matter is that we instantly measure the state its been in since entanglement.
