comment Is a suit that hides a soldier's heat signature fundamentally possible?
Yes these would need power, but with enough energy could be done.

Evaporation of water can keep the suits surface at ambient temperature, just as we keep cool when it gets hotter outside than our body temperature.

comment Do objects launched from Earth retain the Earth's lateral inertia (67,000mph)
The voyager was helped by this, otherwise it would have fallen into or near the sun and gotten incinerated. Orbital mechanics are more complex when you consider the influence of the suns gravity, but it still starts out with the 67k boost.

comment Resource cost and noise effects in quantum teleportation of multible (entangled) qbits
I guess its not obvious it will work because you have to observe each qubit you get, and observing a qubit will destroy entanglement with other qubits. But somehow it does not.

comment Why are crystals so useful for quantum isolation?
So crystal periodicity is conducive wave function coherence, it seems.

That answer is exactly what I was looking for. Do you have references?

comment What's the escape velocity of Naked Singularities?
Imaginary escape velocity simply means that particles placed there will shoot outward to infinity (an another universe, perhaps?). The RN singularity is REPULSIVE. That being said, anything within the inner horizon isn't thought to be RN geometry, as "mass inflation" results.
