Please explain to me quantum entanglement.. and can we “ hypothetically “ build a quantum entangled cameras or some sort of optical device one we can observe on and them put this device in a space shuttle or smt then we can observe events in time ?
Let’s just say this device is 1 light years away but it’s entangled with a device here on earth so events will reach us 1 in 1 year or just in time?

From my limited understanding in an ELI5 way entanglement is particles that have mutually exclusive but related states.
Classic analogy is like a pair of gloves (or shoes). The pair is related in that there’s always a right and a left one.
if you split up the pair into 2 boxes you know one box has a left glove the other a right. If you open up one box you know what the other contains.
the second half of the “spooky action” is the superposition that their state in the boxes is undetermined and “collapses” to a known state. “Hidden variables” or the idea that one box definitely always has a left and one box definitely always has a right has been disproved through some fancy statistical analysis.
So the reality is more, you close your eyes, split up the gloves into boxes then suddenly both boxes contain one glove that is simultaneously a left and a right glove at the same time. The original mutual exclusivity is the same. if you open up one box the other definitely contains the other pair but the glove you get is actually completely undecided until you look and there’s no way to coerce a given box to reveal a given glove so you can’t transmit any data since you can’t manipulate the final state. also you can’t look at the box and “know” that the state has now been set since the only way to know is to look in the box and that would count as well looking and thus determine the state anyway.
long and the short of it is that even though we know something is happening across distances for all intents and purposes it works just like if you split your gloves into boxes randomly and they were always there the whole time and there was never a superposition.
