Return to the Heisenberg uncertainty principle to see how quantum uncertainty also extends to energy and time. This has a startling implication for energy conservation, suggesting that short-lived “virtual” particles can pop into existence out of nothing (as long as they don’t stay around for long). Consider evidence for this phenomenon in the Lamb shift and Casimir effect.
