    Nice, much better than my current sex life although if you would be kind enough to lend me one of your sex robots it might not be.

    Slowing down at other star systems why was I born in the twentieth century.

    It's late. But without overly optimistic attitudes there's only entropy.

    Cherenkov Radiation : Particles Faster Than the Speed of Light?

    Cherenkov radiation occurs because the particles ++are++ going faster than light....in the propagation medium.

    The limit is the speed of light when there is no medium.

    A random neuron fired and occasioned the musing: can the speed of entanglement be slowed?

    I don't think there is a "speed of entanglement". Particles are created in an entangled state and remain so until the state decays, wherever they happen to be.

    It's like painting two things the same colour. Would you talk about "the speed of green" as they separate?

    Depends.
  20.  
    Typical usage of the phrase "speed of entanglement" refers to how fast the correlation is established following a measurement of one of the components. Currently the lower bound is on order 104 c, IIRC.

    Of course, most believe that the actual answer is "infinitely fast".
