Well done Virtuosity98, you got it on your last attempt.
Sound Wave!
The only place it can't exist is in a vacuum, but to even test this, we'd have to make a special machine within a vacuum chamber (man-made) and without the aid of this machine we are unable to be in the vacuum to try to create one and hear nothing, which we can't do without creating a separate environment to sustain our life in which has to be air and so, sound waves exist there. We can capture a sound wave on magnetic tape, Compact Disks and many more devices via a pick up or microphone, We can see it on an oscilloscope as well as see it with our own eyes when passing through / acting on small loose minerals / soft substances, hear it with our ears, feel it with our touch senses, the pinball wizard (deaf dumb & blind kid) could even feel it. It shrinks or stretches into a lower frequency as it travels across molecules and eventually runs out of energy and dies, everything can produce it and if we were able to stop turbine and combustion engines from losing energy via sound waves & heat, they'd be 75% more efficient. We can mix sound waves in harmonic patterns to be very soothing and comforting to humans and animals, we can also use them as a weapon by focusing them like a laser & high energy sound waves from things like explosions can really damage our ear drum receivers, so quite dangerous, we can also use them as Ultra Sound and this can be kept at a safe intensity to produce remote images & can also be made to cause such intense vibration as to break apart what ever it is focused on and so acting like a remote knife / hammer. They last longer and travel further at some frequencies that humans are not capable of receiving, but they are still there nonetheless. You can find a sound wave anywhere that there are molecules, its vehicle.
