You can MEASURE the spin or charge of an entangled pair, but altering it to a spesific outcome means you break the entanglement. The FTL communication is properly impossible.

It may have uses in quantum computing or cryptography, but communication it is not.

I knew about methane, but only just learning about ethanol now, and found a 2011 paper about interstellar ethanol. But what I can’t find is the astrochemical model for how this ethanol is thought to originate from non-biotic processes??? Is there an abiotic process for the genesis of ethanol? Here on earth you’re pretty well restricted to bacteria or yeast options to ferment glucose.

Sorry to piggy back your comment, but do you happen to know of the process or can you point me to a good source about this topic since you had a pre-existing familiarity with it?

Almost positive this has already been done. Only saying "almost" because I wasn't in the (well documented) room.

Entangle two particles, whatever happens to the first happens to the second...regardless of distance separating them.

If a person were to say, alter the spin or charge of a quantum entangled pair of particles, the same alteration happens to the entangled pair....in real time. No delay, regardless of distance.

The Chinese have already used quantum entangled particles to demonstrate FTL communication between their terrestrial comms and their space station. Old news.

This is not a question of whether?...it's a question of what's next?

Entangled particles can transport information instantly and can well be used for transmission of information, used eg in quantum cyrptography. It will probably depend on the definition of "faster of tje speed of light" as you would have to separate two entangled particles (or more btw) and transport one portion with the (current known) restriction of the relativity theory to another place - probably far below the speed of light. I'd believe that the use of entangled particles would probably be rather a "secret" communication tool as it probably will not become cheap and has some restrictions like limited amount of information. However it does not need any direct line of communication.
