I want to know the answer to the following question:
What states that the conservation of energy is a consequence of the fact that the laws of physics do not change over time?
All the background I'm provided with is that "Thus, since 1918, theorists have understood that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time.". Is that enough to answer the question?
Answer: no
