Some creatures are so quiet, they appear to make no sound at all.

"There are at least 200,000 species out there singing in ways that are silent to us, and that's way more songs than if you add up all of the birds and the fish and the whales and the frogs out there," says Rex Cocroft, a biologist at the University of Missouri who is fascinated by creatures that only use vibrations to communicate.  

Cocroft recently managed to record the sound of a treehopper. The treehopper shakes their abdomen 100 times a second to produce a low sound that vibrates through the stem of the plant they are standing on. While that sound is audible to other treehoppers, it’s outside the frequency that humans can hear. Cocroft had to use a specialized piece of equipment, a vibrometer, which uses a laser to detect minute vibrations on the surface of an object. Using this, he was able to record the sound and allow us to hear treehoppers in conversation. 

There was a new animated Disney movie that came out last year that did not perform too well at the box office. Named Wish, the film included a song that tried to explain all of the deep mysteries of the universe. Questions such as - Where did we come from? Why are we here?

The answer - according to the song - is for us to realize that we all came from the stars.

From the song, I’m a Star:

Have you ever wondered why you look up at the sky for answers?

Or why flowers in the wind are effortless and eloquent dancers?

What forms the rings in the trees? Turns a pine from a seed?

What's passed down generationally, to you? (And to me?)

And why our eyes all look like microscopic galaxies?

Have you ever wondered why you look up at the sky for answers?

If you really wanna know just who you are

You're a star (yes!)

The song packed a very surprising punch that the music was careful to build up to:

Here's a little fun allegory

That gets me excitatory

This might sink in in the morning

We are our own origin story

A recent FB post makes these "astronomical" oberservations:

Want me to tell you something that will blow your mind or make you lose sleep?

Well, look at this picture.

Each of those dots you see is a GALAXY ...

And each GALAXY has roughly 100 BILLION STARS.

Also, each STAR has at least 1 PLANET.

Now how many galaxies do you think there can be in that picture?

And this is just a photograph of a very little parcel of the universe. — Astro Physics
