A scientistclaims to haveperfected a technique in which he can spontaneously convert an electroncompletely into energy in the laboratory without any other material required. What is the conclusion about this claim from our current understanding of physics ?

Answer»

This is possible because Einstein's equation says that mass and energy are equivalent....it is just very difficult to achieve with electrons
This is possible and it is DONE all the time in the high-energy physics labs.
The scientist is almost CORRECT... Except that in convertingthe electron to energy, an electron's anti-particle is produced in the PROCESS as well
This is not possible because charge conservation WOULD be violated.

Solution :Charge is conserved. In ORDER to fully convert an electron into energy, a positron (the electron's antiparticle must be involved). That is, electron + position `- gt` energy, NOT electron `- gt` positron + energy.
