    Questions:

    Did the Big Bang make any noise?

    I find this answer totally unsatisfying.

    If a tree falls in the forest and nobody is there to hear it, it does not make a sound.

    Absolutely not. First, there was no viable medium for the propagation of sound waves - there would have been only plasma (I guess, depending on where you are in time); no atomic particles, no air or water or solids through which sound would normally propagate, and more importantly there would be no ears to receive the sound waves even it there were a mechanism to propagate them. No ears, no sound, to ronmac's point. You already know I'm sure that the term "Big Bang" was a pejorative one coined by the astronomer Fred Hoyle who had contempt for the theory.

    P.S. I know it was a rhetorical question in levity but being a smart ass, I couldn't resist.

    It was rhetorical, but also serious. Sound requires a medium to propagate through, and during the Big Bang it is debatable (see the link above from Professor Cramer) whether any such medium existed.

    It's also a mental exercise. How can there be a Bang without any sound? If the universe itself was expanding, what would such waves travel through? If the universe was expanding at the speed of light (or maybe faster, according to recent speculation?) how fast would "sound" waves have to travel?

    As I said, it's a simple question with some rather weighty issues that make it considerably harder to answer than a simple yes or no.

    This is one of the fallacies of sci-fi movies like Star Wars. How can one "hear" the Death Star exploding in the vacuum of space?

    There was no vacuum in the instants after the Big Bang; no matter as such either. All was highly compressed energy. Can sound propagate in pure energy? Yes: energy vibrates. But the "volume" of energy is equivalent to temperature. That initial bang is still echoing across the universe ever more faintly (that is, at ever lower temperatures: it's currently about 2.75 Kelvin), and shall do so till the Heat Death or the Grand Gnab, whichever comes first.

    Exactly! It makes a wave which remains a wave until it is received by an ear to convert it to a sound. The sound is inside the head only.

    If they managed to make a recording of it, people would immediately start complaining about how it was brickwalled or how it sounded better on vinyl.

    Excellent point. Totally missed that. Anywho, thanks for the thought provoking question. Now we can get back to analyzing Jon Anderson lyrics.

    Dave, I think you got closer to the truth than any of us!

    You've probably heard the other take on this:

    If a man speaks and there is no woman to hear him, is he still wrong?

    We are still waiting for the sound wave to arrive.
