I try to keep my self appraised of the current news in the field.
I can not say I fully understand it, and thus the questions I am about to ask. Question #1  If you have 21 entangled atoms, and one was separated for x distance and then used for data transference, would the data transferred to the other 20 atoms affect or apply to them equally (if any)? and if so, in what ways and forms and types could this energy be transferred or altered into? for it would seem to me that if one affects 20, then the same would hold true for 1 for 1000. for even though they them selves have the same energy as the one and could only transfer the same, the others by shear numbers would affectively generate much more energy. a single ant may not be able to move a large leaf, but many of them together can. New forms of abundant energy, and if possible, negating the need for copper wire or electric lines, or perhaps even car batteries, with direct wireless transference. Just a thought.  Question #2 At some point in the history of the universe, it seems to me the conditions for entanglement would have been naturally achieved. and if so then therefore it would seem to me that we would or could find naturally entangled atoms and the like, perhaps out in space or flying through the universe. if such could be found then wouldn't it seem plausible to use what's found to spy on what's happening in the other parts of our universe? perhaps as seen through a type of entanglement degeneration?

#1 NO, multiple particle entanglement does not work this way. There are perhaps thousands/millions of permutations. Even 3 is complicated. The 2 case is more straightforward.
#2 We don't know if we are entangled or not. However, decoherence theory suggests that residual effects would be minimal after a relatively short time on a planet (interacting with other matter).

Quantum Entanglement: Questions
can antimatter be entangled?
 In the regions of where we suspect darkmatter resides (coldspace), could a lasting entanglement occur?

What do you mean by "entangled" here? As long as you can keep antimatter far enough away from matter (which is not an easy task in our matterdominated environment), it behaves pretty much like matter (thanks to the CPT theorem). So you can, in principle, produce entangled states with antiparticles as with particles.
