The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
Entropy
Entropy Is Always Generated at Any Space and Time Scales and Cannot Be Destroyed by Any Means. Entropy is generated everywhere and always (and thus overall increased), at any scale without exception (including life processes, open systems, micro-fluctuations, gravity, or entanglement). nostr:note18kreyzv2cc6km04e0tll570snluug9mqlhrjw43h9u637nnj3fxqvyf9mk
