Question

how can an electron have infinite energy?​

Answer 1

Answer:

Infininite Energy

Explanation:

Since a particle and its antiparticle can annihilate each other and their fields, it follows that such annihilation of point particles should produce photons of infinite energy. ... Therefore electrons and positrons cannot be point particles

Answer 2

Answer:

Since a particle and its antiparticle can annihilate each other and their fields, it follows that such annihilation of point particles should produce photons of infinite energy. The mutual annihilation of an electron and a positron produces gamma ray(s) of finite energy.
