Einstein’s Bubble Paradox of 1909

Einstein formulated this thought experiment or bubble paradox in 1909 to argue that atoms emit light as discrete particle or photons rather than continuous waves. In classical electromagnetic theory, an atom should emit radiation as a wave in a radiating sphere 4π spreading out in every direction, like an inflating soap bubble. When the wave hits another atom, it would pop and the energy spread around the circumference would be focused in that one place, while ceasing to exist elsewhere. That would be a nonlocal process or what Einstein called spooky action at a distance. In other words how would the distant parts of the bubble know that they should cease propagating outwards? Later Einstein extended the bubble paradox from light waves to the quantum wave particle function of quantum mechanics. Mainstream Physics has no explanation for such an event. If light is a wave that acts as a particle when it is absorbed and emitted by an atom the bubble would expand at the speed of light, so any communication between opposite sides would have to occur faster than light. The great thing about the bubble paradox is that it is easy to visualize and comprehend, and in many ways the complex paradoxes of Quantum Mechanics like Nonlocality, Quantum Entanglement, Superposition and the Measurement Problem are all base on this simple little bubble paradox.
