Just stumbled across this on the Web, and thought others might find it as interesting as I...

    All I get is a "We couldn't find that page."

    Works for me with Firefox. The video is also here... http://all-that-is-interesting.com/important-image-captured-by-hubble

    Watched it last night, saw it just fine using IE10 on Win8. Amazing what they found with their "potentially wasted telescope time" looking at a "dark hole in the sky".

    The commentary stated that some of those distant galaxies are racing away from us "faster than the speed of light"...Even though it was in the early sixties when I studied Relativity I am under the impression that C is still an absolute.

    Space can move faster than the speed of light (the big bang and inflation theory).

    Some speculate that eventually everything out there will be moving faster than the speed of light from us, and the universe will be dark (or perhaps ripped). Of course that won't happen in my lifetime.

    Hal Albach,

    Well the deal is that if things are moving away from us they start to look more red. The faster they are going away the more red they become. Think of it as a Doppler shift. Like the change in pitch of a jet aeroplane
    flying by.

    Now, as we observe galaxies out there sure enough they get to look more red as they running away from us.

    Worse still we see that the further away they are the redder they get. That is to say the further away things are the faster they are running away from us.

    Conclusion is that at some point things are far enough away that they are running away from us faster that the speed of light. At that point we can no longer see them.

    What's that about?
    They are traveling away fast enough that the light emitted can never get here?
    Or, they are traveling away fast enough that the red shift is so severe that the frequency has dropped to zero. At which point we can't measure what speed it travels at.

    Anyway, never mind, space and time, and hence the speed of light are just an illusion. Enter the "amplituhedron”:

    For such an insignificant speck in the humongous entity that is the universe we sure make a lot of noise!
