The Vacuum Catastrophe
Quantum Feidl Theory posits that every infinitesimal is imbued with a bit of energy, actually a great deal of energy, called the zero point energy. That is ok since its the difference in energy that matters, but not to General Relativty. Now the discovery of dark energy provides a measure of the zero point energy and the the quantum prediction is spectacularly wrong.

Zero-Point Energy Demystified
It's time for Matthew to do some debunking. According to Quantum Field Theory empty space is loaded with a tremendous amount of energy which has become a popular power source for all manner of exotic spacecraft engines. Sorry. They won't work.
