“Everything in Life is Vibration” Albert Einstein
Quantum physics shows us that nothing is actually solid, atoms are made up of vortices of energy that are constantly vibrating, on a sub-atomic level we do not find matter only energy.
Anything you See (ophthalmoception), Hear (audioception), Taste (gustaoception), Smell (olfacoception), Touch (tactioception); in fact everything we are aware of is made up of energy and it vibrates; even the “stuff” we are not aware of vibrates.
Sight humans can see a spectrum of colours from red to violet, many animals, such as bees, fish, reptiles and amphibians can see ultraviolet wavelengths invisible to humans.
Hearing range for humans is between 20 to 20,000Hz, animals can hear at frequencies much higher than this, like bats at around 100KHz that’s 100,000Hz.
So even though we can’t see or hear certain frequencies (vibrations), doesn’t mean they don’t exist!!
