In a pair-instability supernova, the pairproduction effect causes a sudden pressure drop in the star's core, leading to a rapid partial collapse.

This equivalence is exemplified in a large number of physical processes including pairproduction, nuclear fusion, and the gravitational bending of light. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There are five different methods for pairproduction by lasers. One can easily distinguish the different mechanisms, the one with the lowest threshold being electromagnetic pairproduction. The effect is often described as resulting from virtual pairproduction on the horizon of a black hole. Relativistic oscillation of charged particles in laser fields and pairproduction. Laser intensities are needed for pairproduction in a vacuum. Here we discuss the conditions of different pairproduction models for lasers in view of the present day laser irradiation with focused petawatt and much higher next generation laser pulses. Laser generated pairproduction and hawking-unruh radiation. Neutral particles with internal quantum numbers can mix with each other through virtual pairproduction.

The equations may also need modifications to account for pairproduction of electron-positron pairs (or other particles at the highest temperatures).

The reverse process, pairproduction, is the dominant mechanism by which high-energy photons such as gamma rays lose energy while passing through matter.

Positrons may be generated by positron emission radioactive decay (through weak interactions), or by pairproduction from a sufficiently energetic photon.
