Here's why:

* Time is a fundamental aspect of the universe: Time is not something that can be manipulated by celestial events. It's a dimension in spacetime, and its flow is consistent throughout the universe.

* Gravity affects time, but not in the way you're thinking: Einstein's theory of relativity tells us that strong gravitational fields can cause time dilation (time moving slower in a strong gravitational field), but the moon's gravity is not strong enough to have any noticeable effect on time.

* New moons are just a phase: A new moon is a phase of the moon where it's not visible from Earth because it's positioned between the Earth and the Sun. It doesn't have any special gravitational or energetic properties that could affect time.

Time warps are a concept from science fiction. They are not based on any real-world scientific understanding. While the concepts of time dilation and wormholes are real in physics, they are not related to the moon's phases or the occurrence of a new moon.
