Zero-point energy (ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. Richard Feynman and John Wheeler calculated the zero-point radiation of the vacuum was so powerful that even a small cup of it would be enough to set all of Earth’s oceans to a boil.

What would a ZPE look like? Here's one possibility.
