Entanglement of particles, the "spooky action" Einstein talked about and was deflected from pursuing can do amazing things. Though Einstein was pulled away toward creating nuclear bombs for WWII, his initial studies on particle entanglement are the legacy that could change humanity for the better.

How wonderful that particle entanglement could help us see actions in living tiny cells and other small particles. RD has often said that smashing things together in particle accelerators is no way to understand particles. All that is left are remnants and pieces. "Atom" means indivisible, but of course, we know there are many smaller things than atoms like quarks. Perhaps our knowledge of particles will expand exponentially with entanglement!

Understanding entanglement is how we will learn to communicate across vast distances in real time. It is how we will learn to overwrite a fish or another life-form on another world by looking through the eyes of one here. These things both require entanglement, something our alien overlords use constantly to explore and communicate.

Aliens also use particle entanglement against us to overwrite those whose bodies they wear like clothing. This we must find a way to interrupt!

Of course, they will try to sabotage our efforts. Be strong physicists! Carry on!
