Basically, we know that superpositions exist because we can perform experiments in which, if a particle were always in one state or the other, the results would be different. See: double-slit experiment. If photons didn't exist in a superposition of states, then the distribution of light you'd get with the double slit would be the distribution you get from having one slit covered plus the one you'd get from covering the other one. But you don't--the distribution is completely different, which means that a single photon somehow travel though *both* slits and "interferes with itself." It's more than a little batshit.
I realize you were making a joke based on a perception common in popular culture, but the truth is that the Schrodinger's Cat paradox has a simple resolution: the cat *cannot* be both alive and dead because the detector (which detects whether the decay has occurred and which triggers the release of the poison if the decay occurred) collapses the wave function of the particle. There's no such thing as a passive detector. So while a subatomic particle could indeed exist in a superposition of "decayed" vs. "not decayed," the second you go about asking the particle whether it's decayed (that is, when you set up the detector), the wave function collapses, and no superposition is possible.
So this isn't really my field, but as I understand it (lol at their definition of "non-technical") the idea is that you have two "entangled" particles, separated by some arbitrary distance. If you change something about the first particle, and then send a signal to the second particle (this signal being composed of "classical" information, basically 1s and 0s), then you can make it so that the second particle is an exact copy of the first. Right now they're just at the "qubit" level, but presumably if this scales, you could take a large physical object (a person) and copy them on a quantum level to a distant location by sending a signal of "classical" data. I'm not sure how you go about creating the "entangled you," though.
Quantum teleportation isn't "simultaneous." It appears to require the transmission of classical "bits" of information, which is limited to the speed of light. No causality- or Eisenstein-breaking paradoxes here.
Well sure, but in many-worlds, it's also alive because you never put it in the box*, and it's also a dog, and it also passed straight through the walls of the box and into the Earth's molten core.
*Not to say that conscious decisions are directly quantum events, but quantum mechanics causes thermal fluctuations, and the brain is likely chaotic enough that the right fluctuation at the right time could create a different decision. The odds of all this happening are infinitesimal, but according to many-worlds, as long as it was nonzero, it must have still happened in some universe.
The truth is, relativity doesn't have to be as confusing as it's usually made out to be. The most accessible explanation I've found for time dilation came from Brian Greene's The Elegant Universe:
Suppose you have a race car that can only go 100 m/s, no faster, no slower. Suppose it's racing down a very wide track that's 1km in length . Depending on the angle at which the car travels, it may cross the finish line in 10 seconds, 20, 50 or however long, just no less than 10 seconds. So similarly, we can think of our journey through the universe as happening along a "time" direction as well as three "space" directions: the faster we travel through space, necessarily the slower we travel through time, but no matter what, we're travelling at c.
The math even works out, in terms of c=sqrt(v_x^2+v_t^2) where "v_t" (your velocity through time) is c*dtau/dt.
This analogy obviously only gets you so far, and the real "wow" of relativity comes from the concepts of simultaneity (I wish more SF authors realized that FTL and time travel are the same friggin' thing), but especially for non-majors this is a great way to get one's foot in the door and begin to understand what is a pretty alien concept.
The photons themselves are still traveling at c. What's "slowing them down" is that they're being absorbed and re-emitted by the atoms in the medium. The speed of light is absolute.

That still counts as "on-the-internet" (unless you somehow have a dedicate line going from the POS to the server), so you're plenty vulnerable to spoofing and man-in-the-middle attacks.
First off, Ricardo Montalban wasn't exactly Othello material for "Space Seed." Secondly, I can't think of a *better* casting decision for an arrogant egomaniacal superhuman than Bandersnatch Cummerbund.
We're getting some common carrier stuff, ISPs can't prioritize the traffic from their parent/subsidiary companies... and it sounds like high priority non-controversial "fast lanes" (I don't mind my internet running a little slower so someone can get their MRI transmitted faster) are the only ones getting the green light. So did we win? Or am I missing something?

The information being transmitted isn't binary 1s and 0s but full quantum states. See: qubit.
The key is that it's not classical data, as in 1s and 0s, it's "quantum" data, as in, the very fuzzy states of physical particles.

Exactly my point. The light in Cherenkov radiation isn't travelling faster than c, it's just going faster than the "c" for that medium.

I frankly can't understand how any business that does anything remotely technical can get away with not using the word "critical."
For using all 69 words. No exceptions, right?

What if you attached an IFF system to the mine?

I wonder how long it will be until Google, Microsoft, and Apple are also all producing TV shows.
Microsoft produces (or, at the very least, distributes) The Guild .
