We investigate shock-wave solutions of the Einstein equations in the case when the speed of propagation is equal to the speed of light. The work extends the shock matching theory of Smoller and Temple to the lightlike case. After a brief introduction to general relativity, we in…

The collision of cosmic projectiles with a terrestrial planet’s surface forms topographic depressions, known as impact craters. Since planetary surfaces are continuously bombarded, these features can be observed on nearly all solid bodies in the Solar System. On airless bodies w…
