All matter in the universe is interconnected, therefore, it’s all entangled.
One particle in any part of the universe is at all times, interacting with any other particle in any other part of the universe, and all particles in the universe are all interacting. There is no particle in the universe which does not ‘know’ about every other particle.
We all (people and everything) did come from the one single first particle that started the whole universe. If everything is derived from the one single particle that comprises the whole universe, then of course, all things in the universe are entangled.
Are you sure?
