Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
The search for and development of efficient terahertz (THz) sources is one of the major scientific goals of the 21st century. The THz region of the electromagnetic spectrum is composed of light frequencies in between the ...
