Einstein’s Bubble Paradox of 1909. The faster than light Thought Experiment explained as a process of energy exchange

                                       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
