Ask the Dreadlocked Science Geek

OK, I lied dreadgeek. I do have a query.
Sound waves travel through matter. Is there a formula for how sound waves penetrate matter? Are there densitiies that they cannot go through? When sound passes through the human body, will certain frequencies pass quicker than others? Is there a scientific reason for why the heart beat will tune to the drum line of music, such as certain molecular structures being more absorbant/or resistant to sound waves? And what is the difference between a wave and a vibration?

Dear Dreaded Science Geek,

Why do bugs die on their backs? Or maybe more accurately, why do I always find dead bugs on their back, legs in the air, and never belly down, like maybe they're just taking a little nap?

Confused in Atlanta

Dear Dreadgeek,
This is SO cool! I have done a little bit of self study in Astronomy, probably just enough to confuse myself...I've learned that in order for a theory to be viable it has to be able to make a prediction. From the little that I've learned, the estimate of the temperature at the time the universe was created, the idea that the universe will keep expanding, the fact that the universe started out as a place of extreme density...I tend to think we are actually inside a black a hole in a larger universe. The temperature and density inside a black hole seem quite similar to the start of our universe. Mathematically, black holes have the same (I believe) properties to the edge of our universe. What I think really sells me on the idea is the dark matter and dark energy. Inside a black hole, the universe that the black hole resides in would not be able to detect what is going on inside the black hole, but inside the black hole, I would imagine the universe outside of it would be detectable. This dark matter, could it be a universe outside of our universe? I get frustrated because I hear scientist are interested in the topic, but I haven't found much on scientist really exploring the topic. I guess, in my mind, a point of infinite density doesn't seem possible. Mathematically, that is what happens, but it doesn't seem logical...It seems like something would give. Like the matter would convert into energy or it would invert itself and start expanding infinitely apart. Hope this made sense.
Anyway, just curious of your thoughts...
