  • Question of the Day (29/11)

    :: If the speed of light is 299 792 458 m/s, what is the speed of dark?

  • #2
    Darkness does not exist, it is merely a human term given to absence of light. This is in the same vein as cold, cold itself does not exist, it just refers to the absence of heat to an extent.

      the speed of dark is the same as light. in other words if your in a room without any light source except a litebulb and you turn that lightbulb off, who fast does it get dark? the absence of light travels at 186,000 miles per secound. unless your watching a sunset! and like a refridgerator, cold is the absence of heat. your refrigerator doesnt make the milk cold. it extracts the heat from the milk.

        There must be some reaction time between the light turning off and the darkness "filling" the room, as light and dark do not coexist, or?

          where does the light go? :shock: oh my brain hurts! :x

            The light bursts on the scene in a blaze of glory, but retreats slowly.

            The reverse is true of the dark: it vanishes like a thief in the night, but creeps up on you gradually.

              But is it arriving as particles (photons) or as waves (setting up interference patterns)?

              Is its speed the Universal Speed Limit? I read Hawking one time (until my brain froze up - then I got out my 'Calvin & Hobbes' collection (excellent Xmas gift - the collected set, retail $150, but I've seen it for $99) and thawed my brain), and learned the following [caution - Brain Freeze Zone]:

              If you have a molecule of Oxygen (or Hydrogen or any two-of-the-atom molecules) - O2 - the atoms spin in opposite directions (up or down). But the direction they spin is totally dependent on the observation, i.e., one time it's spinning up, the next instant it's down (feeling frosty yet?).

              BUT . . . (insulate brain immediately), if you separate the two atoms and move them to opposite sides of the universe (roughly 35-40 billion light-years apart, I seem to remember), and observe the spin of one of the atoms, its twin will always be the opposite, SO . . . (owww) if you observe one up, the other will instantly be down. How is this 'communicated'?

              Now build yourself a quantum computer, the one that uses the quantum levels of atoms as its 1s and 0s, and use the spins as your binary data, and your computer can transmit information across the universe INSTANTLY (OWWW!). How's that for busting the Speed Limit? ["How fast was I going, Officer?" . . . "Uh, infinity."]

                i like totally get it dude. and infinity.....nothin. the last 100m of an all out 800. dont tell me al einstein didnt go to the track.

                  YOU probably do! I'm too left-brained to get it. You right-brained people grasp the inconceivable a lot easier. 8)

                    the only thing i havent figured out yet is as follows-

                    we can go to the moon but we cant make instant mashed potatoes taste better.

                      I have a degree in physics and I work for a major food company, so maybe I can answer this.....

                        oh my goodness, mcgato, you may be my only hope. and if you are, i will finally know everything. :P

                            I bet Steven Wright never said that the speed of light was 299,792,458 m/s in his life. :wink:

                              My favorite Steven Wright joke:

                              I was walking along the street the other day and all of a sudden I couldn't see a thing... the prescription for my glasses had expired.
