In this movie, Dr Quantum explains the difference between matter and waves. We all know that there's a connection between mass and waves through Einstein's famous formula. (E = mc2; energy = mass times the speed of light (3,00 x 100.000.000 meter per second) squared, and that mass and energy are directly related. That means simply that every element in the universe, every planet, every piece of life, every plant, every animal, and so also mankind exists solely out of energy. Einstein already showed that mass is a slowed form of energy, like a traffic jam on a high way.
If energy in its turn exists exclusively out of waves, we deal with a permanent change. With as a consequence that our human body is far from static, but the result of a group of waves that chances constantly and is entwined for 80 years like a coil of many strands of ropes. Strands that come out of our body and continuously make invisible contact with others. Then the waves unbraid, carry on and a human disappears like there never was anything at all.
