The universe extends so far in every direction that no matter where you look, you get objects receding from you at the speed of light.
Just to be clear, the highest redshift object is galaxy IOK-1 with a redshift of z = 6.96, which is nowhere near high enough for the object to be moving away from us at nearly the speed of light.
If your boss demands a password, you have to give it, by law. If he demands you give it to another person, or 20 other people, you have to give it, by law.
What insane country do you live in where not obeying what your boss is a crime? In the US private sector, employees enter a contract with their employers. Not doing what your boss says is probably a violation of that contract (which will likely get you fired), but it won't get you prosecuted for a crime.
I qualified the above with "in the US private sector", because this doesn't apply to certain public sector jobs (i.e., elected/appointed officials), public safety jobs, and, of course, the military.
The Executive, Legislature, and Court are supposed to balance each other.
The Legislature in no way has complete primacy in the US form of representative democracy.
True. If anything, the Executive branch has evolved to have primacy over the others (cf. http://en.wikipedia.org/wiki/Imperial_presidency).

Are you seriously suggesting a government should be able to force a private company to stop working on its own product and work on some other organization's product? That's a slippery slope that leads to a world I don't want to live in.
And has that ever happened in the history of antitrust litigation?
If Bill or Amy flip a coin, then instantly the other one KNOWS the other person flipped a coin at that point in time.
Nobody has said that. How can Bill's measurement force Amy to make her measurement at the same time? That's not possible. Especially since "at the same time" has no meaning for spacelike-separated events (cf. the Relativity of Simultaneity).
This is what happens: Bill measures a random value. Amy measures a random value. The two values are both random, but 100% correlated with each other. Bill knows what value Amy measures and vice versa, but no information has been transmitted, because the values are random.
I don't think you can tell when a particle is measured without measuring it which then collapses the waveform anyway.
Sort of. Neither side can tell when the wavefunction collapses due to the other side performing a measurement. Both sides see completly random (but correlated) results from their measurements. It is that randomness that prevents superluminal signaling.
So does this mean it is possible to send information using entangled particles, but we just have no idea how to do it?
No. Superluminal signaling leads to reverse causality (future events affecting past events), and that's widely considered impossible.
We shall entangle two particles and you shall have one and I shall have one. You will "collapse the waveform" or whatever these Star Trek raised modern physicists want to call it on an even second to send a "1" and on an odd second to send a "0". Since I will instantly see the change on my magic fairy dust atom we shall be able to send information by measuring the time of the change. Sure, our bandwidth won't be real hot, but it's a good experiment, no?
No. You will not "instantly see the change" to your entangled particle/atom. You must perform a measurement that _always_ gives a random result. The only thing QM promises (and it's quite a promise) is that your random measurement result will always be perfectly correlated to the random measurement result at the other end. This happens even if the two measurement events are so far apart there is not enough time for a signal to move at lightspeed between them.
Weird, huh?
He can't. He's basically saying that his measurements will impose a pattern on the series of particles one one side, and a correlated pattern on the series of particles on the other side. The _problem_ is that the patterns are random on both sides.
Seriously, FTL signaling enables reverse causality (i.e., future events affecting past events). And that just isn't going to happen.
The states aren't genuinely undetermined, it's jus that we don't know what it is. However, it's also the wrong explanation - because of http://en.wikipedia.org/wiki/Bell's_theorem. A brilliant bit of work that showed you could in fact test and measure whether there were such local hidden variables. There aren't. Quantum weirdness won the battle.
This is true, but to be clear, Bell's Theorem shows that the correlation between spatially-separated measurements predicted by local-hidden-variables theories is less than the correlation predicted by QM (i.e., QM predicts the measurements are _more_ correlated than local hidden variables can make them). Now that the experiments have been performed, QM is generally considered the winner.
