TWSB: The Sound of a Solar Re (and a Do, a Mi, a Fa, a So, a La, a Ti, and More Do)

The authors of the Ask a Mathematician/Ask a Physicist blog received and answered this question not too long ago: If you could hear through space as though it were filled with air, what would you hear?

The answer is as follows: the sun.

Yes, our big showy center of the universe is also the loudest thing around, at least to us. The Physicist explains: both the loudness and brightness of an object is exactly proportional to how big it is. The sun’s brightness, therefore, is a function of its temperature and size. If a small ball of the same temperature as the sun were to be held up so that it appeared to be the same size as the sun, it would feel exactly as warm and seem exactly as bright as the sun.
Taking this comparison of a small bright ball = distant, huge sun with respect to the amount of heat omitted, The Physicist states that the sun, if we could hear it, “would be exactly as loud as any other large-marble-sized nuclear explosion held at arm’s length.”

So we’d pretty much be deaf. Or dead.

30-Day Meme – Day 19: A talent of yours.
Rewriting song lyrics. I swear this is my single talent in life. Like I said in my “100 Things” list, I credit my mom playing a lot of Weird Al when I was a kid. It comes very naturally to me. Here are a few examples:

• Justin Timberlake’s Sexy Back rewritten as Easy Mac.
• Boston’s Peace of Mind rewritten as Piece of Pi.
• MC Hammer’s U Can’t Touch This rewritten as U Can’t Prove This (it’s about logic class and how long it took  me to wrap my head around proofs).

1. “Solar Re,” not bad, not bad. I would have gone with “Sol-fège” myself.
