The premise is made up. The physics behind it is real: why toast lands butter-side down, the odds of a perfect shuffle, the second law of thermodynamics as statistics, how a fridge dumps heat, quantum tunneling in your phone's memory and in the Sun, particles as clouds of probability, black hole entropy, and how small Earth would be as a black hole.

Earth as a black hole: Schwarzschild radius 2GM/c² ≈ 8.9 mm (about 1.8 cm across); Earth's mass ≈ 5.97 × 10^24 kg, about 6 sextillion tonnes
NASA: the International Space Station orbits Earth about every 90 minutes, about 16 sunrises a day
The Moon's orbit depends only on Earth's mass, not its size
