Theory 31: Nothing in the Universe Is Ever Truly Destroyed
1. The conservation of matter
Matter cannot be completely destroyed or created from nothing. In chemical reactions, atoms are only rearranged to form new compounds, but the total number of atoms and the overall mass of the system remain constant. When wood burns, for example, it turns into ash, carbon dioxide, and water, but the total mass of the substances involved does not change.
2. The conservation of energy
Energy likewise cannot be destroyed or created from nothing; it is only converted from one form to another, as when chemical energy becomes heat or kinetic energy. In an internal combustion engine, the chemical energy of fuel converts into kinetic energy.
3. Einstein's theory of relativity
Einstein showed that matter and energy can convert into one another, as expressed in the famous equation E = mc². This means matter can become energy and energy can become matter, but the total amount of matter and energy in the universe remains constant.
4. Exceptions and special cases
At the quantum scale, particles can appear to arise from nothing or vanish, as in particle-antiparticle pair production, but these processes still obey the laws of conservation of energy and electric charge. In black holes, matter and energy appear to disappear, but according to newer theories such as Hawking radiation, information and energy are in fact preserved at the black hole's event horizon.
In conclusion, nothing in the universe is ever completely erased or destroyed; only its form changes. This principle is one of the essential foundations of physics and chemistry.
