1. Let's clarify the problem: You want to understand how gravitational influence works over large distances, such as from the center of our galaxy to Earth, or from Earth to a very distant place in the universe. 2. Gravitational influence is described by Newton's law of universal gravitation, which states that the force $F$ between two masses $m_1$ and $m_2$ separated by a distance $r$ is given by: $$F = G \frac{m_1 m_2}{r^2}$$ where $G$ is the gravitational constant. 3. This formula shows that gravitational force decreases with the square of the distance. So, the farther away two objects are, the weaker the gravitational force between them. 4. Therefore, the gravitational influence from the center of the galaxy on Earth is much stronger than the influence Earth would have on a place billions of miles away, because the distance $r$ is much smaller for the galaxy center to Earth than Earth to that distant place. 5. If Earth were alone in the universe, it would still exert gravitational influence on distant objects, but this influence would be extremely weak due to the large distance. 6. So, the gravitational influence is not the same everywhere; it decreases with distance squared, meaning it is stronger closer to the mass and weaker farther away. Final answer: Gravitational influence is not uniform across the galaxy or universe; it decreases with the square of the distance between objects, so it is stronger near the mass and weaker far away.
