Beyond Einstein and E = mc2

The book critically analyzes Einstein's 1905 paper on E = mc2, suggesting that while the equation has been understood qualitatively since Newton, a deeper examination reveals contradictions. It posits that when light energy is emitted, the mass of a luminous body must increase, challenging the concept of perpetual energy. The author argues that Einstein's derivation of the light energy-mass interconversion equation is valid only under specific conditions, highlighting the limitations in understanding energy and mass relationships.
