The concept that particles can interact with each other despite time and distance in so cool…a particle across the universe knows what direction the other particle is spinning.. A way to bridge and create instant communications in the future. I think…

Unfortunately not.

The thing is, it’s not quite right to say that “when one changes spin the other also changes despite distance and time”…

It’s more that both are uncertain until you measure one, and in doing so you provide a certainty to both. You can’t actually communicate instantaneously, but you can get together later and check that your results are more correlated than they would otherwise be.

It’s pretty complicated, but it is very interesting when you start to get into it.
