Gravitational Radiation

Just as the classical theory of electricity and magnetism predicts that accelerating charges will give off electromagnetic radiation, general relativity predicts that certain types of systems should give off gravitational radiation.

It is more complex, causing a brief distortion of space-time geometry when a gravity wave passes. Systems like closely orbiting objects or collapsing bodies are expected to produce gravitational radiation. Direct detection attempts using large detectors have not succeeded, but a laser interferometer program aims to improve sensitivity. The most compelling evidence comes indirectly from studying a binary pulsar system, where observed orbital energy loss aligns with predictions for gravitational radiation.
