Resonance, waveforms and what I thoughtfor a second was a wormhole.

"The basic building blocks of the universe seem to be either waves or vibrating strings, and most of the things they make up move in bigger waves and vibrations. If we hope to understand much about the physical workings of the universe, then we need to have some idea about the way that waves and vibrations work. The details of wave motion vary, but many of the principles are universal."
