I'm new to physics. And I have curiously wondering about the relationship between matter and energy. From what I understand, one can create the other, but is it truly creating or just aiding in the process?
Matter can definitely be created without violating conservation of energy. All massive particles (e.g electrons, quarks, etc) have a minimum energy called their rest energy, which is given by $E=mc^2$. This energy is stored as the mass of the particle. A particle can be created as long as there is energy at least equal to its rest energy, so that energy is conserved, and all other conservation laws are obeyed (e.g momentum, charge, lepton number, etc). Matter can also be destroyed to release energy. The rest energy of the particles is released and photons are produced when a particle meets its antiparticle. The energy of the photons is equal to the combined rest energy and kinetic energy of the particle and antiparticle, so energy is conserved.
