• Strange noise in sky?

    A few days ago I was outside waiting for the bus and I heard what sounded like a truck passing by in the distance, until that sound evolved into an echoing noise that would be similar to the sound of flopping sheet metal. It rippled a few times and I never heard it again. Any ideas of what this might be?

  • DO YOU KNOW ABOUT MIRRORS?

    I'm currently writing a film about mirrors where reflections come out of mirrors... but I need help coming up with a scientific reason that reflections can come out. Can you come up with a way that can sound kind of believable and allows reflections to exit the mirror.

  • How can the speed of light be squared in Einstein's E=MC2 formula if nothing exceeds light speed?

    And I have heard it be told that the math does not suggest that is actually faster than light, but help me out, I'm slow - C squared is double the speed of light (I know it doesn not have to be light). Anyway, therefore, my natural inclination is to interperet that if something traveled twice as fast as light,... show more
    And I have heard it be told that the math does not suggest that is actually faster than light, but help me out, I'm slow - C squared is double the speed of light (I know it doesn not have to be light). Anyway, therefore, my natural inclination is to interperet that if something traveled twice as fast as light, it becomes mass. That's what this suggests to me. If people are saying the math does not mean you need to have light travel twice as fast in order to create matter, what's the purpose of the mathematical phraseology?
