If the moon has grown to twice its size while still remaining in the same place, the main factor that would impact the gravity between the Earth and the moon is the distance between them.
Gravity is directly proportional to the mass of the objects and inversely proportional to the square of the distance between them. In this scenario, if the moon has indeed grown to twice its size, its mass would have increased too.
Assuming that the distance between the Earth and the moon remains constant, the increased mass of the moon would result in a stronger gravitational pull between the two bodies. This would cause an increase in the gravitational force exerted by the moon on the Earth and vice versa.
Consequently, with a larger moon, the tides on Earth may be more pronounced due to the increased gravitational force pulling on the oceans. Similarly, the Earth's gravitational pull on the moon would also be stronger, potentially affecting any geological or astronomical phenomenon associated with the moon's orbit or rotation.
However, it's important to note that this scenario contradicts our current understanding of celestial bodies and their growth patterns. The moon is not known to increase in size while remaining stationary in its orbit. This answer assumes a hypothetical situation based on the provided information.
