Abstract
One of the oldest and most controversial unsolved problems in physics comes from electrodynamics. For over a century it has been known that an accelerated charged particle creates a radiation field and this field acts back on the particle that created it. Some theories that describe this self force have been formulated over the years but are often plagued with unphysical predictions, such as runaway solutions or violation of causality, while others are only valid if the self force is small. Theoretical arguments have been raging for years because no experiment has been devised that can test the putative solutions. However, with ultrahigh intensity lasers an experiment might be at hand that can shed light on this pesky issue, and might even determine the correct theory, ending a century old debate.
