What do you think about telepresence robots. Operated from earth, anywhere in the galaxy, instantly.

“In our lifetimes”..huh. People during their lifetimes in the first half of 20th century thought too that heavier then air flight is impossible..quite a few of them lived long enough to see man landing on the Moon. Your point?

Faster Than Light is theoretical. But, it may exist, we just won’t know in our lifetimes.

If an electron can emit a photon, and the characteristics of the electron can be deduced based on the characteristics of a photon, then they are in a sense entangled. I believe that is how we should be perceiving this technology in its current state.

but I though that information could n be sent faster than light?
If it shows to be possible, then off course the theory or at least that part is wrong. But I imagine it (if possible) as a old fashion telegraph. Beep Beep Bepbepbep Beeep

This will be a great way to control the drones that watch what Iran is doing, just as long as you have a fiber-optics cable stretching all the way to where the UAV is based.

Now take this some way into the future. Imagine storing entangled electrons in storage rings, placing half of a pair in a ring on a space station, the other half in a ring on a star ship. Then, years later, when the ship is light years away, it can tap out a coded message by changing the spin. By spooky action at a distance, the electron back at the space station will change its spin at the same time, giving you faster-than-light communications.
