Why don't we see vibrations when we hear music or people talking?

• The vibrations are too large.

• The vibrations are going too fast.

• The vibrations are too small for us to notice.

Why can't you hear sound in outer space?

• There is too much oxygen in outer space so the air is too thick to vibrate.

• There is no air in outer space so there is nothing for sound to vibrate.

• The air is filled with too many space particles so it can't vibrate like here on Earth.
