How is matter and energy conserved in the universe
Answer (1)
Conservation of Energy: The total amount of energy in a closed system remains constant. Energy can change forms (e.g., from kinetic to potential, or into heat), but it cannot be created or destroyed.Conservation of Matter: In a closed system, the total mass remains constant over time. While matter can change forms (e.g., through chemical reactions), the total amount remains the same.In the broader context of the universe, these principles are upheld by the conservation of energy-momentum. Matter and energy can transform into each other (as described by Einstein's equation E=mc²), but the total amount of energy and matter (or mass-energy) in the universe remains constant.
