Zero-point energy

Zero-point energy is derived from the quantum field theory that underpins the vacuum state: the vacuum, while seemingly empty, is filled with virtual particles constantly popping in and out of existence. These fluctuations contribute to the zero-point energy, which is ubiquitous throughout all of space-time. This intrinsic energy manifests as the baseline level of energy present in the fabric of spacetime and can be harvested, resulting in nigh-limitless energy availability.

As the literal "background residual energy" of space-time, zero-point energy is indeed available everywhere, all the time. However, its nature raises several challenges:

• it is not an intense form of energy
• it seems to somehow be disrupted by the presence of nullspace fields
