Albert Einstein called it “Spooky action at a distance.” Modern physics calls it “quantum entanglement.” Simply put, it means that if any part of a single system is removed from that system to a different location, any action performed on the part will also be instantaneously performed on the parent system, and vice versa. Spooky got his name from Einstein’s famous saying.
The “2” isn’t a software version number – it stands for “squared”. 2 is the classical physical formula E = mc², which tells energy interrelationship.
This is why we name spooky2.
