What experimental evidence do physicists have for the direct transformation of energy into matter?
A) increase in the force upon a body when it is accelerated upward (e.g., in an elevator)
B) conversion of gamma-ray photons into electrons and antielectrons (i.e., positrons)
C) blueshift of light because of the motion of its source
D) relativistic increase in mass of an object when it is moving very rapidly

Question

Quizplus · Accepted Answer

The conversion of gamma-ray photons into electron-positron pairs is a direct demonstration of the transformation of energy into matter, as described by the equation E=mc^2. This process, known as pair production, is a clear experimental evidence supporting the theory that energy and matter can be converted into each other.
