What energy value overcomes Earth's gravitational binding energy for a planet the size of Earth?
$2.24 \times 10^{32}$ Joules
The energy required to completely disassemble a planet the size of Earth, making it disperse into space, is defined by its gravitational binding energy. This specific physical calculation yields a requirement of approximately $2.24 \times 10^{32}$ Joules. This figure is astronomical; for context, it represents the total energy output of global human civilization for well over 370,000 years based on 2020 consumption rates. This immense energy must be generated and focused instantaneously by the superlaser. The energy source capable of theoretically approaching this density is matter-antimatter annihilation, where nearly 100% of mass is converted to energy according to $E=mc^2$.
