"If you were in a Dyson Sphere..."

Hello, John and Doves,
If you were in a Dyson Sphere, "up" would be toward the Sun.
We are not in a Dyson Sphere, but for the purposes of this discussion, "up" can still be taken as meaning, "towards the Sun."
If the Moon is at the "top of its phase," then that could mean the Moon is new.  The Moon is directly between the Earth and the Sun, so it is as far "up" as it will ever be during any Jewish month.
